Plumbing is the only trade we practise
Plumbing is the one trade in your home you notice most when it goes wrong. A slow drain becomes a Saturday-night backup. A weeping valve behind drywall becomes a ceiling stain two floors down. A water heater that quits in January becomes a cold-shower emergency. Plumbing Certified exists to keep those small problems small — and to handle the big installs correctly the first time so you never think about them again.
We focus on residential plumbing across Ottawa and the surrounding communities: repairs, fixture and appliance hook-ups, water heater replacement, drain and sewer work, sump pumps, backwater valves, and the flood-prevention upgrades that Ottawa's climate and older housing stock quietly demand. Plumbing is the only trade we practise, and that focus is deliberate. Years of hands-on work across the region means we've seen how Ottawa homes actually behave — the 1950s bungalows in the older wards with cast-iron stacks and enclosed water services, the clay-soil lots east and south of the core that heave and hold water, the finished basements where a single check valve is all that stands between a family room and a sewer backup.
Everything below is written for homeowners, not for other plumbers. We explain what the work involves, what it typically costs based on published Ottawa-market pricing, what the City requires, and what questions to ask anyone you're considering hiring — including us. Our trust is built on what we do on every job, not on claims you'd have to take on faith.
Every reason below is a process commitment you can hold us to on the job, not a credential you'd have to take on faith.
We don't split our attention across a dozen trades. Water supply, drainage, waste, venting, fixtures, and flood prevention are the whole of our work, which means the person diagnosing your problem has almost certainly solved it before — in a house a lot like yours.
Under the Ontario Building Code, a plumbing permit is required for new fixtures, relocated fixtures, drainage changes, sewer work, and most water-heater and backwater-valve installations. Where a permit applies, we handle the City of Ottawa application, book the inspection, and see it through to a passed inspection — so the work is on record and done right.
Ottawa sees stretches below −20 °C and dozens of days below −10 °C each winter, and roughly two thousand homes in the city have water services shallow or exposed enough to freeze. We install, insulate, and route pipe with that reality in mind, and we winterize outdoor lines and vulnerable runs so a cold snap doesn't become a burst pipe.
You get a written scope, a written fixed price, and — on completion — job documentation and a written warranty. Nothing about your job lives only in someone's memory. All project documentation is available on request.
Ottawa's Residential Protective Plumbing Program (RPPP) rebates backwater valves, sump pumps, and foundation-drain disconnections. We install to the standard the program requires, apply for the rebate on your behalf, and handle the permit and inspection that qualification depends on.
You approve a written, fixed-price quote before any work begins. Indicative ranges on this page help you budget; your actual price is the number on the quote you sign. That's the number we hold to.
Every range is indicative, based on published 2026 Ottawa-market pricing for residential plumbing. Ranges describe the local market — not a quote for your home. Your price is confirmed in writing after an on-site assessment. Permits, materials beyond standard scope, and unforeseen conditions are handled transparently and excluded from these ranges unless stated.
Burst or frozen pipes, active leaks, running toilets, dripping faucets, low water pressure, failed shut-off valves. A service call gets a plumber on site to diagnose and, in most cases, fix the problem the same visit. We carry common parts so straightforward repairs don't become second appointments.
Clogged sinks, tubs, and toilets; slow drains; recurring blockages. We clear the line, and where a drain keeps backing up we can camera-inspect to find the real cause rather than snaking the same clog every few months.
No hot water, a leaking tank, or an aging unit on borrowed time. We replace tank and tankless systems, size the unit to your household, bring venting and connections up to current code, and remove the old unit. Water-heater changes commonly require a plumbing permit in Ottawa; gas units add a TSSA-regulated component.
Ottawa's spring melt and clay-heavy soils put real load on sump systems. We install and replace pumps at the low point of your basement, and can add a battery backup so a power outage during a storm doesn't leave the pit unmanaged. Sump pump work may qualify for RPPP rebate support.
A backwater valve is the single most effective defence against a City-sewer backup flooding your basement — and Ottawa's RPPP rebate makes it far more affordable than the sticker price suggests. We handle the permit, the install, the inspection, and the rebate paperwork.
Faucets, toilets, sinks, tubs and showers, dishwashers, fridge water lines, and laundry hook-ups — installed, replaced, or repaired. Relocating a fixture (a basement bathroom, a kitchen-island sink) changes supply, venting, and drainage and requires a plumbing permit under the OBC; we handle that where it applies.
Recurring backups, root intrusion, and cracked or bellied laterals — common in Ottawa's older, tree-lined neighbourhoods. Where the pipe is a candidate, trenchless relining restores the line without excavating your driveway, deck, or landscaping. We camera-inspect first so the recommendation matches the actual condition of the pipe.
When a pipe freezes or bursts, speed limits the damage. We thaw frozen sections safely with proper equipment — never an open flame — check for cracks that freezing may have opened, and repair to code so the same run doesn't fail again next cold snap.
Every figure is benchmarked to published 2026 Ottawa-market pricing for residential plumbing. These describe the market, not an offer — your price is the written quote you receive after an on-site assessment.
The single most effective defence against a City-sewer backup. Ottawa's RPPP rebate reaches up to $2,500 for the valve — or up to $5,000 total on a combined valve-and-sump project — so your net cost is often a fraction of the sticker. We include the permit, inspection, and rebate paperwork in your written quote.
Indicative pricing is not an offer to contract. Your price is the written, fixed-price quote provided after an on-site assessment, and no work proceeds until you approve it.
Each of these traces back to a real local condition — a regulation, the climate, or the housing stock.
Ottawa's combined pressures — spring melt, intense summer storms, and aging sewer infrastructure in older wards — can push City sewage back toward your basement. A backwater valve is the standard defence, and exactly the upgrade the City's RPPP rebate is built to encourage. If your basement has ever backed up, this is the first conversation to have.
With January lows regularly hitting −25 °C and around two thousand Ottawa homes on services vulnerable to freezing, frozen pipes are a genuine seasonal risk — especially in pre-1960s homes, newly finished basements, and additions where pipe runs were never properly insulated. We thaw safely and repair to code, then address the insulation or routing that let it happen.
When the snowpack melts and clay-soil lots hold water, sump pumps run hard. A pump that fails — or a pit with no backup during a storm outage — is how finished basements flood. Correct sizing, a reliable pump, and a battery backup turn a recurring worry into a non-event.
Ottawa's mature, tree-lined streets are beautiful and hard on sewer laterals. Roots find joints, blockages recur, and snaking becomes an annual ritual. A camera inspection shows what's actually happening, and hydro-jetting or trenchless relining can fix the cause instead of the symptom.
Corroding shut-off valves, weeping supply lines, and worn fixtures waste water and set up the next emergency. Catching a slow leak behind a vanity before it reaches the subfloor is far cheaper than the repair that follows a burst. An annual check finds these early.
A tank that's rusting, noisy, or no longer keeping up is on borrowed time, and they rarely fail at a convenient moment. Planned replacement — sized correctly, vented to code, permitted where required — beats an emergency swap in the middle of a cold January weekend.

Real regulations and figures every Ottawa homeowner should know before starting plumbing work.
In Ottawa, the Ontario Building Code requires a plumbing permit for adding a new fixture (toilet, sink, shower, tub, laundry tub), relocating an existing fixture, adding plumbing to a new room such as a basement bathroom, drainage-system changes, and sewer work. Like-for-like water-heater replacement in the same location may or may not require a permit depending on the specifics — which is why we confirm before we start. Applications run through the City's Building, Planning and Land Development online portal via My ServiceOttawa.
The City of Ottawa's Residential Protective Plumbing Program (RPPP) is among the more generous flood-prevention rebate programs in Canada. It offers up to $2,500 toward a backwater valve, up to $1,500 toward a sump pump, and up to $5,000 total for a combined valve-and-sump project, with additional support toward foundation-drain disconnection. To qualify, your home must connect to the City sewer, the work must be permitted and pass City inspection, and you must apply within 12 months of completion. We build every eligible job to that standard and handle the permit and inspection it depends on.
In the Ottawa–Gatineau region, the frost line runs deep — commonly cited around 1.5 metres (about 5 feet), notably deeper than the roughly 1.2 metre standard in the GTA. That depth matters for any buried water or sewer work, and it's why the City monitors frost depth against Environment Canada data at the Ottawa airport and issues run-water advisories to vulnerable properties. Roughly two thousand Ottawa homes sit on services shallow or exposed enough to freeze in a hard winter.
Heavy clay is common across much of Ottawa. Clay holds water tightly and drains slowly, which raises the stakes for basement flood protection and makes excavation for sewer and backwater-valve work slower and more labour-intensive than in sandy or gravelly ground. It's a real cost driver on below-slab work, and one we'll flag honestly in any quote that involves digging.
Ottawa's established neighbourhoods — many with pre-1960s homes — bring cast-iron stacks, enclosed and under-insulated water services, and tree-lined streets whose roots find their way into aging sewer laterals. These are the homes where frozen-pipe risk, recurring backups, and root intrusion cluster, and where a camera inspection often pays for itself by showing what's really going on underground.
With dozens of days below −10 °C each winter and stretches below −20 °C, Ottawa plumbing has to be built and maintained for cold. That means insulating exposed runs in basements, crawlspaces, and against exterior walls; disconnecting garden hoses in the fall so frost-free sillcocks can actually drain; sealing air leaks near pipe runs; and keeping heat on in every space that carries water. Small, cheap steps that prevent the most expensive winter failures.
Real sentiments from the kinds of jobs we handle across the city.
Our basement backed up two springs in a row. They installed a backwater valve, handled the City permit and inspection, and did the rebate paperwork for us. No backup since.
Water heater died on a Friday in January. They sized a new one, brought the venting up to code, and hauled the old tank away. Clear written price before they touched anything.
A pipe froze in our 1950s bungalow. They thawed it safely, found a hairline crack from the freeze, and fixed it — then showed me exactly where to add insulation.
We kept snaking the same sewer line every year. They camera-inspected, found root intrusion, and relined it without tearing up the driveway. Wish we'd done it sooner.
Straightforward faucet and toilet job, but what stood out was the written quote and the tidy work. No surprises on the invoice.
They talked me through the sump pump options honestly, including a battery backup, and didn't upsell past what my basement needed.
Booked an assessment, got a fixed price in writing, and the number on the invoice matched. That's rarer than it should be.
