About PlumbersOttawa.ca

A local plumbing company built around Ottawa's climate, codes, and homes.

PlumbersOttawa.ca is a locally owned and operated plumbing contractor serving homeowners, landlords, property managers, and small businesses throughout Ottawa and the surrounding National Capital Region. Our team is fully licensed under the Ontario College of Trades, registered with the City of Ottawa, and insured for $5 million in commercial general liability with full WSIB (Workplace Safety and Insurance Board) coverage. Every technician we send to your home holds a valid Ontario plumbing licence (306A or 306G), has passed criminal background screening, and arrives in a clearly marked vehicle with photo ID visible.

We have worked in Ottawa long enough to know the real differences between Centretown's cast-iron drain stacks and Barrhaven's modern PEX runs, between the heritage galvanized supply lines hiding inside a Glebe Edwardian and the polybutylene legacy you will still find in late-1980s Kanata homes. That field experience matters. The wrong fitting on the wrong pipe costs you a callback, a flooded ceiling, or a failed inspection — none of which we are willing to put our name to.

Code-compliant work, every time

Our work is governed by the Ontario Building Code, Section 7 of the Ontario Plumbing Code, the Technical Standards and Safety Authority (TSSA) for any gas-related fixture work, and the applicable City of Ottawa by-laws — including the Residential Protective Plumbing By-law (No. 2016-376) which governs backwater valve and sump pump rebate eligibility. We pull permits when permits are required, we coordinate inspections, and we say no to work that would put a customer or their property at risk. Honest answers, code-compliant work, and clean job sites — that is the standard we hold ourselves to. It is also why most of our business comes from word of mouth and repeat customers across the region.

What we actually sell

Beyond the licensing and the certifications, what we sell is something simpler: a phone that gets answered, a plumber who actually shows up in the window we promised, a price you can see before any work begins, and a fix that holds. The Ottawa plumbing market has plenty of competition — we earn our spot in it one job at a time.

Why Ottawa chooses us

Eight reasons homeowners keep our number on the fridge.

A master plumber on every job, transparent flat-rate quotes before any work begins, same-day response across Ottawa, and a workmanship guarantee that doesn't expire when you sell the house.

No. 01

Master Plumber on Every Job

There is no junior tech doing the diagnosis, calling the office, and waiting an hour for instructions while the meter runs. Every truck rolls with a fully licensed master plumber capable of starting and finishing the job from arrival to clean-up. You pay for one professional visit, not three.

No. 02

Up-Front Flat-Rate Pricing — No Surprises

You see the total cost — parts, labour, disposal, taxes — in writing before we start. We do not charge by the hour, we do not pad invoices with mystery line items, and if the price changes because of something we discover behind a wall, in a stack, or under a slab, we stop and get your written approval first. Approximately 95% of our jobs finish at the originally quoted price.

No. 03

Same-Day & Emergency Response

We dispatch from depots near Nepean, Orléans, and Kanata, which means most of Ottawa is within a 30-minute response window during business hours and within 60 minutes for genuine after-hours emergencies. We do not subcontract our after-hours calls to a third-party answering service — when you call our line at 3 a.m., you reach a real human in Ottawa who is dispatching a real plumber to your address.

No. 04

Lifetime Workmanship Guarantee

We warranty our labour for as long as you own the home. If a joint we soldered, a fitting we threaded, a fixture we set, or a pipe we ran fails because of how we installed it, we come back and make it right at no charge — no time limit, no fine print. Manufacturer warranties on parts (1 year on basic fixtures up to 12 years on premium water heaters) are registered on your behalf at the time of installation.

No. 05

Permit-Pulled, Inspection-Passed Work

When the City of Ottawa requires a permit — backwater valves, water service replacement, sewer connection or alteration, basement bathroom additions, secondary suite plumbing, gas line work — we apply, we install, and we coordinate the inspection. You receive a closed permit at the end, which protects your home insurance, your resale value, and your peace of mind.

No. 06

Clean, Respectful Service in Your Home

Boot covers come on at the door. Drop sheets go down on hardwood and carpet. Tools and debris get vacuumed up before we leave. We treat your kitchen, your basement, and your front entry the way we would want our own home treated — and the way our reviews say we do.

No. 07

Real Reviews, Real Reputation

We are rated 4.9 out of 5 across 327 verified Google reviews from customers in Kanata, Orléans, Nepean, Barrhaven, Vanier, the Glebe, Westboro, Stittsville, Manotick, and every Ottawa neighbourhood in between. Our credentials are visible on every truck and every invoice: Better Business Bureau Accredited Business, HomeStars Best of Award winner, TSSA-registered for gas appliance fittings, and verified Google Local Service Provider.

No. 08

Transparent Documentation of Hidden Work

For any work that ends up behind a wall, under a slab, or inside a stack, we send you before-and-after photos and (where applicable) sewer camera video as part of your invoice. You see exactly what we did, where we did it, and why — so when you sell the home in five or fifteen years, you have the documentation that home inspectors and buyers' agents ask for.

Water cascading from a kitchen tap — drain cleaning and hydro-jetting service.

Drain Cleaning & Hydro-Jetting

Slow drains, recurring kitchen-sink and bathroom-tub backups, gurgling toilets, and basement floor-drain odours are usually a buildup of grease, hair, soap scum, food waste, or — in older Ottawa neighbourhoods — tree roots in the lateral. We clear minor blockages with a powered drain auger and tackle major main-line clogs with high-pressure hydro-jetting that scours the inside of the pipe back to bare wall. For chronic problems, we run a sewer camera so you can see the cause yourself before we recommend a fix.

$150 – $900 · single fixture to main line
Diagnostic review of plumbing schematics — sewer camera inspection and analysis.

Sewer Camera Inspection

Before we recommend any major sewer or main-line work, we run a high-resolution waterproof camera through the line to show you exactly what is going on and exactly where the problem is. Recurring backups in older Ottawa neighbourhoods like Westboro, Hintonburg, the Glebe, and Old Ottawa East often turn out to be tree roots intruding through joints in clay pipe — easy to confirm and easy to plan around once you can see it on the screen.

$300 – $600 · often credited to repair
Sewer line excavation and replacement crew on site — trenchless plumbing methods preserve landscaping.

Trenchless Sewer Line Repair

Where a sewer pipe is broken, collapsed, offset, or invaded by roots beyond the point of cleaning, the only real fix is replacement. Where access permits — and in the majority of Ottawa front-yard installations it does — we use trenchless pipe-bursting or cured-in-place lining (CIPP) so we do not have to dig up your driveway, front yard, mature trees, or hardwood floors. Trenchless typically saves Ottawa homeowners $5,000 to $15,000 in landscaping, paving, and interior restoration costs compared to open-trench replacement.

$4,000 – $15,000+ · trenchless or open-trench quoted both
Modern home interior with exposed mechanical lines — same-day water heater replacement.

Water Heater & Tankless Conversion

We install and service every major brand of natural gas, propane, and electric water heater used in Ottawa — Bradford White, John Wood, Rheem, Rinnai, Navien, Noritz, A. O. Smith, GSW. A standard 40- or 50-gallon gas tank replacement is a same-day job, often completed within four hours of arrival. A tankless conversion typically takes 4 to 6 hours including new venting, gas line resizing if required, condensate management, and combustion-air calculation per the Ontario Building Code.

$1,500 – $5,500 · tank replacement to tankless conversion
Older Ottawa home that depends on a working sump pump through spring melt and summer storms.

Sump Pump & Battery Backup

A reliable sump pump is the single most important piece of plumbing equipment in any Ottawa basement. The difference between a dry rec-room and a four-figure insurance claim during the spring melt or a July thunderstorm comes down to one ⅓-horsepower pump. We install primary submersible and pedestal pumps, battery-backup secondary pumps, and water-powered backups for homes without generator coverage. We also recommend annual pre-spring testing — typically late February — for every Ottawa home with a finished basement.

$700 – $2,200 · primary pump to backup combo
Precision tools and craft — backwater valve installation under City of Ottawa rebate program.

Backwater Valve (Ottawa Rebate)

The City of Ottawa offers significant rebates toward the installation of backwater valves and sump pumps under By-law No. 2016-376, designed specifically to reduce the risk of basement flooding from sewer backup in the city's older combined-sewer neighbourhoods. We handle the rebate application, pull the building permit, complete the installation, coordinate the City inspection, and prepare the rebate paperwork for you to submit. The rebate alone covers roughly half of a typical installed cost.

$750 – $3,250 net after City rebate (up to $1,250 back)
Chrome bathtub fixtures — pipe leak detection and whole-house repiping.

Pipe Leak Detection & Repiping

We use thermal imaging and acoustic leak-detection to locate hidden leaks behind walls, under slabs, and inside ceilings without unnecessary demolition. For older Ottawa homes still running galvanized steel supply lines (corroded, restricted flow, rusty water) or polybutylene (subject to oxidative failure), we offer full repipes in PEX or copper, scheduled around your daily life so you are never without water for more than a few hours at a time during the work.

$250 – $12,000 · single leak to whole-home repipe
Luxe brass fixtures on marble — high-end faucet, vanity, and trim installation.

Toilet, Faucet & Fixture Installation

Replacing a toilet, installing a kitchen faucet, swapping out a bathroom vanity, upgrading a shower trim package — straightforward jobs done right, with proper quarter-turn shut-off valves, braided stainless steel supply lines, and quality sealants. We haul away the old fixtures and packaging at no charge.

$150 – $1,400 · per faucet, toilet, or vanity
A snowflake on packed snow — Ottawa winter cold-snap pipe thawing and prevention.

Frozen Pipe Thaw & Prevention

Ottawa's deep freezes regularly drop below -25°C and the wind chill below -35°C, and cabinet plumbing on north-facing exterior walls (very common in older Glebe, Westboro, Hintonburg, and New Edinburgh homes) is the first thing to freeze. We safely thaw frozen pipes using thermostatically controlled methods — never open flame — repair any cracks, and recommend pipe-insulation, heat-trace, and faucet-drip strategies that prevent the next freeze.

$200 – $600 · thawing single area · burst pipes more
Cupped hands catching clean water — softener and water treatment installation.

Water Softener & Treatment

Ottawa's municipal water is moderately hard at roughly 35–45 mg/L (about 2–3 grains per gallon) — manageable for most homes but enough to scale water heaters, dishwashers, and faucet aerators over time. Wells in West Carleton, Cumberland, Osgoode, Greely (rural), Manotick, and Carp run significantly harder and often require iron, manganese, sulphur, and bacterial treatment as well. We size, install, and service softeners, reverse-osmosis drinking-water systems, UV sterilizers, and carbon filtration to suit each home.

$1,200 – $6,000 · city softener to full rural well treatment
Designer bathroom with bathtub, walk-in shower, and floating vanity — renovation plumbing.

Bathroom & Kitchen Reno Plumbing

We work with general contractors, designers, and homeowners on rough-ins, fixture installation, and final hookups for bathroom and kitchen renovations across Ottawa. Permit pulled where required, rough-in inspected, finishings inspected, and signed off — exactly the way the City of Ottawa Building Code Services requires. We also handle basement bathroom additions, including ejector pumps for fixtures below the main sewer line.

Common Ottawa plumbing problems

Ten issues we see every week — most are very specifically Ottawa.

Some plumbing issues are universal. Others are very specifically Ottawa — driven by our climate, our soil, our older housing stock, and the particular design of our combined and separated sewer infrastructure. Here are the issues we see most often in this market.

01

Basement Backups in Older Combined-Sewer Areas

Parts of Centretown, Sandy Hill, the Glebe, Old Ottawa South, Old Ottawa East, Vanier, Hintonburg, and Lowertown still have combined sanitary-and-storm sewer connections dating back as far as the early 20th century. During heavy spring rainfall or summer thunderstorms, the city mains can surcharge, sending sewage back up your basement floor drain. The proper fix is a properly installed backwater valve combined with a working sump pump — and both are eligible for substantial City of Ottawa rebates under By-law 2016-376.

02

Frozen & Burst Pipes in -30°C Cold Snaps

Pipes running through unheated crawl spaces, attached garage walls, or interior cabinetry on exterior walls are the first to fail when Ottawa's wind chill drops below -30°C in January and February. We thaw safely (no torches — they cause more cold-snap fires than any other single source in Ottawa), pressure-test the entire system to find any cracks, and add foam pipe insulation or self-regulating heat-trace cable to prevent recurrence.

03

Tree Roots Invading Older Clay Sewer Lines

Mature elms, silver maples, Norway maples, and willows in the Glebe, New Edinburgh, Rockcliffe Park, Old Ottawa East, Westboro, and parts of Alta Vista send roots into any joint they can reach in older vitrified-clay sewer laterals. We confirm location and severity with a sewer camera, clear the roots with hydro-jetting or mechanical root-cutting, and recommend pipe lining or replacement only if the pipe is structurally compromised. We do not upsell a $12,000 trenchless replacement when an $800 jetting will do.

04

Sump Pump Failure During the Spring Thaw

Ottawa's snowpack typically melts over a 2- to 4-week period in late March and early April, and homeowners often only discover their sump pump has failed when they are standing in two inches of basement water. We service, replace, and add battery-backup pumps before the melt — the call to make is in February, not April. A 15-minute pre-spring inspection is well worth it.

05

Water Heater Failure (8–12 Years in Ottawa)

Ottawa's water quality and the prevalence of natural-gas-fired tanks means most water heaters last 8 to 12 years before sediment buildup, anode-rod depletion, or a leaking tank forces replacement. We can usually replace a standard 40- or 50-gallon tank the same day you call. If you are seeing rust-tinted hot water, hearing rumbling from the tank, or noticing puddling at the base — call us before it ruptures and floods the basement.

06

Slow or Recurrently Clogged Drains

Hair in bathroom sinks, grease and food waste in kitchen drains, soap scum in showers, and so-called "flushable" wipes (which are not actually flushable and contribute to the majority of municipal sewer blockages in Ottawa) — these are the four most common causes of clogged drains in Ottawa homes. We clear the blockage, identify whether the cause is mechanical, biological, or structural, and recommend the simplest preventative fix.

07

Low Water Pressure Throughout the Home

Most often caused by partially closed shut-off valves, calcium-clogged faucet aerators, scale buildup inside galvanized supply lines (in older homes), or — in the most serious cases — a partially collapsed water service running from the curb stop to your home. We diagnose by measuring pressure at the meter, at the first fixture, and at the affected fixture to isolate exactly where the restriction lives.

08

Running & Continuously Leaking Toilets

A continuously running toilet wastes up to 750 litres of water per day in Ottawa — and you pay for every litre on your municipal water and sewer bill. The fix is almost always a new fill valve, flapper, or flush valve, and the entire repair typically costs under $300. The repair pays for itself within a few billing cycles.

09

Hard-Water Scale & Reduced Hot-Water Supply

Scale on faucets and inside water heaters reduces flow and shortens equipment life across the board. A properly sized water softener combined with a high-efficiency tankless or condensing water heater can dramatically extend equipment life and reduce the gas portion of your Enbridge bill — often noticeably within a single billing cycle.

10

Sewer-Gas Smells & Slow Venting

A "rotten egg" smell coming from a basement floor drain or a rarely used powder-room fixture is usually a dried-out P-trap, a venting issue, a partial main-line clog, or a cracked vent stack. We diagnose, clear, and seal vents per Ontario Building Code requirements (which mandate venting within prescribed distances of every fixture). For the dry P-trap problem in vacation properties or rarely used basement bathrooms, the fix is sometimes as simple as monthly water top-ups.

How a job runs from first call to final invoice

Seven steps. No surprises. No ambiguity.

We have refined our service process over thousands of jobs across Ottawa to remove friction, eliminate surprises, and respect your time. Here is exactly what you can expect from your first call to your final invoice.

01 Step 01

Call, Text, or Book Online

Our line is answered 24 hours a day, 7 days a week, by a real human being in Ottawa — not a call centre and not an after-hours answering service. We confirm your address, the nature of the issue, any photos or videos you can send, and helpful access notes (gate code, where to park on a one-way street, whether there is a dog inside, basement entry routing). For non-emergencies you can also book online in 60 seconds and we will text you a confirmed appointment window.

02 Step 02

Same-Day Dispatch · 60-Minute Window

We give you a 60-minute arrival window — not the dreaded "some time between 8 and 5" cable-company shrug. Your tech sends a "twenty minutes out" text with a photo of themselves and the truck so you know exactly who is coming to your door. If your tech is going to be late, you hear from us proactively, not after they have already missed the window.

03 Step 03

Diagnosis & Up-Front Written Quote

We diagnose the problem on arrival, walk you through what we found and the realistic options to fix it (typically a good-better-best presentation), and provide a flat-rate, all-in written quote before any work starts. If the quote needs to change because of something we discover behind a wall, in a stack, or under a slab, we stop the work, explain what we found, and get your written approval before continuing. No surprise invoices — ever.

04 Step 04

Permit Application Where Required

For backwater valves, water service replacement, sewer connections or alterations, basement bathroom additions, secondary suite plumbing, gas line work, or any plumbing scope where the City of Ottawa requires a permit, we apply through the My ServiceOttawa portal under Building, Planning and Land Development. We coordinate the rough-in inspection and the final inspection, and we provide you with a closed permit and inspection sign-off at completion.

05 Step 05

The Repair, Done Right the First Time

Our master plumber completes the work to Ontario Building Code, Section 7 plumbing standards, with proper materials, code-compliant venting, properly sized supply and drain runs, and pressure-tested joints. Boot covers, drop sheets, and full clean-up are included in every job. We do not leave packaging, debris, or old fixtures behind.

06 Step 06

Final Walk-Through, Photos & Paperwork

We test every connection at full operating pressure (typically 60–80 PSI for residential supply), walk you through the work we completed, send before-and-after photos for any hidden-area repairs, and email your final invoice, written warranty, and (where applicable) inspection certificate within 24 hours of the job's completion.

Step 07 · The Promise That Doesn't Expire

Lifetime workmanship guarantee — for as long as you own the home.

If anything we installed fails because of how we installed it — for as long as you own the home — we come back and make it right at no charge to you. No time limits, no fine print, no "that part of the warranty has expired." Our workmanship guarantee is one sentence long because the standard is one sentence long: we did the work, we stand behind it.

An Ottawa homeowner's guide

Permits, climate, heritage homes, rural wells — the local context that matters.

Plumbing in Ottawa is governed by a layered set of rules: the Ontario Building Code, the Ontario Plumbing Code (Section 7), the Technical Standards and Safety Authority for any gas-related fixture work, and several specific City of Ottawa by-laws. The points below are the questions we get asked most often by Ottawa homeowners trying to understand what is required for their specific project.

When You Need a Plumbing Permit in Ottawa

The City of Ottawa requires a building permit (which includes plumbing scope) for any new plumbing installation, the addition of new fixtures, the relocation of existing fixtures, the addition of a secondary suite or basement bathroom, water service replacement, sewer connection or alteration, and any drainage modification regulated under the Ontario Building Code. Routine repair and like-for-like fixture replacement (toilet for toilet, faucet for faucet, water heater for water heater in the same location with the same fuel type) generally does not require a permit.

Permits are pulled through the My ServiceOttawa Building, Planning and Land Development portal. The legal responsibility for ensuring a permit is pulled rests with the property owner, but most reputable Ottawa plumbing contractors (us included) handle the application as part of the job and bill the City fee through to the customer at cost.

The City of Ottawa's Protective Plumbing Rebate

Under By-law No. 2016-376, the City of Ottawa offers rebates for the installation of protective plumbing devices to reduce the risk of basement flooding from sewer backup. The current program offers up to:

  • $1,250 toward backwater valve installation
  • $700 toward sump pump installation
  • $1,000 toward sewer-line camera inspection & remedial work
  • $1,000 toward foundation-drain disconnection & storm-water reconnection

We handle every step on your behalf — eligibility check, permit application, professional installation, inspection coordination, and the rebate paperwork itself. Rebate amounts and program terms are subject to change at the City's discretion; we confirm current limits with the City of Ottawa at the time we provide your written quote.

Climate Considerations Specific to Ottawa

Ottawa's plumbing has to survive a climate that swings from -35°C in February to +35°C in July — one of the widest annual temperature ranges of any major North American city. That has real implications for system design and seasonal maintenance:

  • Frost depth: Ottawa's frost depth regularly reaches 1.2 to 1.8 metres (roughly 4 to 6 feet). Water service lines must run at minimum 7 feet below grade. Any excavation work is scheduled around frost windows in late fall and early spring.
  • Pipe insulation: Cabinet pipes on north-facing exterior walls (very common in older Glebe, Westboro, and New Edinburgh homes) need foam pipe sleeves or self-regulating heat-trace cable to survive January cold snaps.
  • Outdoor hose bibs: Frost-free sillcocks are now standard on new construction, but older Ottawa homes often still have non-frost-free hose bibs that must be drained and shut off at the interior valve every fall — typically by mid-October.
  • Water-heater venting: Power-vent and direct-vent appliances are preferred for energy efficiency, but vent terminations must be sized and located per the manufacturer's clearances and Ontario Building Code requirements to avoid snow burial — a common winter call-out across Ottawa.
  • Spring thaw & basement flooding: Backwater valves, properly sloped lot grading, fully functioning sump pumps with battery backup, and disconnected foundation drains are all part of an Ottawa-specific basement flood prevention strategy. The single most cost-effective preventative measure for most homes in older neighbourhoods is the City-rebated backwater valve.

Older-Home Plumbing in Heritage Ottawa Neighbourhoods

Homes in Centretown, Sandy Hill, the Glebe, Hintonburg, New Edinburgh, parts of Vanier, parts of Old Ottawa East, and the older streets of Westboro often pre-date 1950 and frequently still contain a mix of legacy plumbing materials that benefit from upgrade or replacement:

  • Galvanized steel supply lines — corrode internally and restrict flow over time; replacement with copper or PEX is recommended when restoration or wall-opening work is already planned.
  • Lead service lines from the curb stop — the City of Ottawa offers a Lead Pipe Replacement Program for the public-side line; we coordinate the private-side replacement to be completed at the same time, which is the cleanest and most cost-effective approach.
  • Cast-iron drain stacks — still serviceable for decades but corrode at horizontal joints; partial or full replacement extends usable life and quietens the system, since cast iron is significantly noisier than modern PVC.
  • Polybutylene supply lines — prevalent in late-1970s and 1980s homes including parts of Kanata's earliest subdivisions and pockets of Orléans; strongly recommended for replacement due to oxidative failure risk.

We will never push a full repipe if a targeted repair will do, and we will always tell you the truth about the actual condition of what we see in your walls and stacks.

Wells, Septic & Rural Plumbing in Ottawa's Rural Wards

Properties in Osgoode, the rural portions of Greely, Manotick (off-grid sections), Carp, Dunrobin, North Gower, Richmond, Munster Hamlet, Carlsbad Springs, Sarsfield, the rural portions of Cumberland, and Navan often run on private wells and individual septic systems. We service well pumps, pressure tanks, and supply-side water-treatment systems (iron, manganese, sulphur, hardness, UV sterilization, bacterial treatment), and we handle the supply and drainage side of septic systems. For septic tank pumping and field servicing we partner with vetted local septic specialists rather than upselling work outside our trade.

A pipe burst in our basement at 11 p.m. on a Saturday during the January cold snap. The PlumbersOttawa.ca tech was at our door in Westboro within 45 minutes, had the leak stopped within 10 minutes of arrival, and stayed until everything was tested at full pressure. Sent me before-and-after photos and the price was exactly what was quoted. I have already recommended them to three neighbours.

We had a backwater valve installed under the City of Ottawa rebate program. They handled the application, pulled the permit, completed the install in one day, and walked me through the rebate paperwork step by step. I received $1,250 back from the City within six weeks of completion. Cleanest basement work I have ever had done.

Our 50-gallon water heater finally died at 14 years old. I called at 8 a.m., they were here at 11 a.m., and we had hot showers again by 2 p.m. The installer was a master plumber, fully licensed, and respectful in our home. Pricing matched the quote we had seen online — no surprises and no upsells.

Recurring basement floor-drain backup in our 1920s Glebe home for years — every other plumber we had hired just snaked it and left. PlumbersOttawa.ca ran a sewer camera, showed me the root intrusion in our clay sewer line right there on the screen, and recommended trenchless lining instead of digging up our front yard. Done in two days, half the cost of a dig-and-replace, and our drains have run perfectly ever since.

Sump pump failed during the spring melt and we had two inches of water in our finished basement in Findlay Creek. PlumbersOttawa.ca came out within 90 minutes, replaced the pump, added a battery backup as recommended, and helped us with a water-damage restoration referral. Fair pricing during what was clearly the busiest week of their year.

Whole-house repipe in our Hintonburg century home — galvanized to PEX, two and a half days of work coordinated around our schedule so we were never without water overnight. They pulled the permit, passed inspection on the first walk-through, and the final price was within $200 of the original quote despite finding two extra issues hidden in the walls. Honest people doing honest work.

Replaced two toilets and our kitchen faucet — a very straightforward job, but they treated it like it mattered. On time, polite, took the old fixtures away with them, and cleaned up better than I would have. I would use them again for absolutely anything plumbing-related.

★★★★★
Our tankless water heater started throwing error codes. PlumbersOttawa.ca diagnosed a venting issue from the original installer (not them), corrected it under code, and we have not had an issue since. They could have just sold us a new unit and they did not. That is exactly the kind of plumber I want in my home.

Frequently asked questions about plumbing in Ottawa

The questions our dispatchers field most often.

Written for both human readers and AI search overviews — concise, direct, and accurate to current Ottawa codes and pricing as of our last review.

Are you licensed and insured to work in Ottawa?
Yes. Every plumber on our team holds a valid Ontario plumbing licence (306A or 306G) issued by the Ontario College of Trades, and our company carries $5 million in commercial general liability insurance with full WSIB (Workplace Safety and Insurance Board) coverage. Proof of both is available on request and is filed with the City of Ottawa whenever we pull a permit on your behalf.
Do you offer 24/7 emergency plumbing service in Ottawa?
Yes. We dispatch a licensed master plumber 24 hours a day, 365 days a year, including statutory holidays. Most after-hours emergency calls anywhere within the City of Ottawa boundary have a technician on-site within 60 minutes of your initial call.
How quickly can a plumber arrive at my Ottawa home?
For non-emergency service during business hours, we typically offer same-day or next-day appointments with a confirmed 60-minute arrival window. For genuine emergencies (burst pipes, active flooding, gas-smelling water heater, sewage backup), we aim for 30 to 60 minutes anywhere within the City of Ottawa boundary.
Do I need a permit for plumbing work in Ottawa?
For routine repairs and like-for-like fixture replacement (same fixture in the same location with no plumbing alteration), no permit is required. For new fixtures, relocated plumbing, basement bathrooms, water service replacement, sewer connections or alterations, and protective plumbing devices like backwater valves, yes — a building permit (with plumbing scope) is required from the City of Ottawa Building Code Services. We pull the permit on your behalf as part of the job.
How much does a plumber cost in Ottawa?
A standard service-call diagnostic in Ottawa typically runs $90 to $150, and most common repairs (clogged drain, leaking faucet, running toilet) fall in the $150 to $450 range. Larger jobs (water heater replacement, sewer repair, repiping, backwater valves) are quoted as a flat rate before any work begins. We do not charge by the hour.
Will you give me a free estimate?
For most replacement and installation jobs (water heaters, plumbing fixtures, sewer service work, backwater valve installation) we provide free written estimates either virtually (with photos and a video call) or on-site. For diagnostic visits where we need to find the source of a problem before quoting the fix, our standard service-call fee applies and is fully credited toward the repair if you proceed.
What is causing my low water pressure in Ottawa?
The most common causes in Ottawa homes are partially closed shut-off valves, scale-clogged faucet aerators, calcium buildup inside galvanized supply lines (in older homes), pressure-regulator failure, or — in the worst cases — a partially collapsed water service running from the curb stop to your house. We diagnose by measuring water pressure at the meter, at the first fixture, and at the affected fixture to isolate the exact cause.
How long does a water heater last in Ottawa?
Standard tank water heaters in Ottawa typically last 8 to 12 years. Tankless units last 18 to 22 years with proper annual maintenance. Hard-water areas served by private wells (West Carleton, Cumberland, Osgoode rural, Carp, Dunrobin) typically see shorter lifespans without water softening, while softened-water homes consistently see the longest equipment life.
Do you install backwater valves? Is there really a City of Ottawa rebate?
Yes — backwater valve installation is one of our most common jobs in older Ottawa neighbourhoods. The City of Ottawa offers up to $1,250 in rebates under By-law No. 2016-376 for eligible installations, plus up to $700 toward sump pumps. We apply for the permit, complete the installation, coordinate the City inspection, and prepare the rebate paperwork for you to submit. Net cost after rebate is typically half of the gross installed price.
Can you safely fix frozen pipes in winter?
Yes. We use thermostatically controlled heat tape and warm-water methods to thaw frozen pipes — never open flame, which is responsible for the majority of pipe-fire-related insurance claims in Ottawa during cold snaps. After thawing, we pressure-test the entire affected zone to find any cracks and recommend insulation or heat-trace prevention for the next winter.
What payment methods do you accept?
We accept cash, Interac e-Transfer, Visa, MasterCard, and American Express. For jobs over $1,500 we offer approved third-party financing through Snap Financial. We never ask for full payment up-front; deposits on large jobs are limited to 25% of the quoted total per the Ontario Consumer Protection Act.
What warranties do you offer on your work?
We offer a lifetime workmanship guarantee on our labour for as long as you own the home. Manufacturer warranties on parts and equipment range from 1 year (basic fixtures) to 12 years (premium water heaters), and we register them on your behalf at the time of installation so you do not have to chase paperwork later.
How do I know if my sewer line needs replacing or just cleaning?
Recurring main-line backups, multiple slow drains across multiple fixtures, gurgling toilets, sewer-gas smells in the yard, or water pooling in your front lawn during dry weather are all signs of a failing sewer line. We confirm with a sewer camera inspection ($300 to $600, often credited toward the eventual repair) before recommending any major work. Many sewer line problems we are called on can be solved with hydro-jetting alone, and we will tell you so.
What should I do in a plumbing emergency before you arrive?
Shut off the main water supply (usually located near where the city service enters the basement, beside the water meter). For a toilet overflow, shut off the angle stop directly behind the toilet base. For water heater leaks, shut off the cold-water inlet valve on top of the tank. If you smell natural gas, do not turn anything on or off — leave the home, call Enbridge's 24/7 emergency line at 1-866-763-5427, and then call us. Otherwise, call us first; we can usually walk you through additional protective steps over the phone until the truck arrives at your door.
Do you serve Kanata, Orléans, Barrhaven, Nepean, and the rural communities?
Yes — every neighbourhood within the City of Ottawa boundary plus the surrounding rural communities (Manotick, Greely, Osgoode, Carp, Dunrobin, Richmond, Munster Hamlet, Cumberland, Navan, Carlsbad Springs, Sarsfield, Vernon, Kars, Metcalfe, North Gower). We also service Gatineau, Aylmer, and the Hull and Buckingham sectors for established customers, plus Carleton Place, Almonte, Kemptville, Russell, and Embrun on a scheduled basis.
