Ottawa's winters are hard on pipes, and a burst line or backed-up drain rarely waits for business hours. This list rounds up ten plumbing companies that actually operate in and around Ottawa right now, pulled from their own websites, Google Business listings, and public review platforms like HomeStars, Birdeye, and the BBB.
1. John The Plumber
Area: Ottawa-wide · Rating: 4.9 on Google (800+ reviews) · Since: 2006
John The Plumber has racked up hundreds of Google reviews over the years, passing 600 and then 800 in posts on its own site, and reviewers consistently point to same-day availability and 24/7 emergency response. It covers everything from drain cleaning to water heater and furnace work, making it a solid pick for anyone who wants one company for the full range of plumbing needs.
2. Dr. Pipe Drain and Plumbing
Area: Ottawa, Nepean, Barrhaven, Kanata, Orleans, Gloucester, Vanier, Embrun · Rating: 5.0 on Google
Based in Nepean with more than 20 years in business, Dr. Pipe holds an A+ BBB rating and a certification from the Insurance Bureau of Canada on backwater valves. Customers on its own review page and third-party sites credit the company with quick response times and upfront pricing, which makes it a reasonable option for anyone who wants a quote before work starts rather than after.
3. Gentlemen Plumbing & Drain Cleaning
Area: Ottawa · Rating: 5.0 on Google
Every public Google review for Gentlemen Plumbing to date has been five stars, and the company is BBB accredited with an A rating. It's licensed, insured, and backs its work with a 2-year warranty, handling everything from drain repair to fixture installation. It suits homeowners who want a smaller, name-recognized outfit rather than a large multi-city chain.
4. Plumbing Now
Area: Ottawa-wide · Rating: 4.6 on Google (33 reviews)
Plumbing Now is a BBB accredited business with an A+ rating and has served Ottawa homeowners for more than 20 years. It's built its business around 24/7 availability and upfront pricing, and reviewers on Birdeye and its own site mention professionalism and quick response as recurring themes. It's a fair choice for anyone who wants a locally established company with a long track record.
5. The Super Plumber - Ottawa
Area: Orleans, Kanata, Nepean, Barrhaven, Manotick · Rating: 4.9 on Google (170 reviews)
The Super Plumber runs a location at 1181 Parisien St in Ottawa and covers drain cleaning, sewer repairs, and water heater installation on top of standard plumbing calls. Reviewers on Connect Ottawa and the BBB consistently mention punctuality and friendly technicians, and the company advertises round-the-clock emergency rescue for burst pipes and sewer backups.
6. Maya Plumbing
Area: Kanata, Barrhaven, Orleans, Stittsville · Rating: 5.0 (52 reviews)
Maya Plumbing is licensed and insured and focuses on 24/7 emergency service across Ottawa's western and eastern suburbs. Its site highlights toilet and faucet repair, drain cleaning, and emergency plumbing as its core offerings. It's a good fit for homeowners in Kanata or Barrhaven who want a smaller, suburb-focused operator rather than a citywide chain.
7. Francis Home Environment
Area: Ottawa-wide · Rating: 5.0 · Since: 1933
Francis has been operating in Ottawa since 1933 and holds an A+ BBB rating, combining plumbing with its longer-standing heating and cooling business. Reviews single out individual technicians by name for personable, knowledgeable service, which points to a company that keeps steady staff rather than rotating contractors. It suits homeowners who'd rather call one long-running local company for plumbing, heating, and cooling.
8. The Irish Plumber
Area: Kanata, Barrhaven, Ottawa · Rating: 4.8 (per TrustAnalytica), 94% StarScore on HomeStars
Owned and operated by Michael Harford, a Red Seal certified plumber with more than twenty years of experience, The Irish Plumber operates 24/7 out of a location on Raven Avenue. Reviews on HomeStars and Wheree describe quick response times and thorough work at reasonable pricing. It's a solid option for anyone who prefers to work directly with an owner-operator rather than a large dispatch-based company.
9. Environmental Plumbing
Area: Nepean, Barrhaven, Orleans, Gloucester, Downtown Ottawa · Rating: 4.8 (74 reviews on Connect Ottawa)
Environmental Plumbing runs three locations across Ottawa and Nepean and is BBB accredited with an A+ rating. It covers emergency plumbing, drain cleaning, water heater repair, leak detection, and sump pump service, and reviews across HomeStars, Birdeye, and TrustedPros repeatedly mention fair pricing and quick response. It's a reasonable pick for anyone in the west end who wants a company with multiple physical locations nearby.
10. Pipes Plumbing Inc
Area: Kanata, Carp, and surrounding west-end communities · Rating: 5.0 on Houzz
Pipes Plumbing operates out of Kanata and Carp, giving it an edge for homeowners in Ottawa's far west end who don't want to wait for a crew based downtown. It holds a perfect rating on Houzz, and reviewers on other platforms call out professionalism and punctuality. It's worth a call for rural and west-end properties that some downtown-based plumbers may be slower to reach.
A note on completeness: ratings and review counts vary by platform for several of these companies, sometimes significantly, since Google, HomeStars, Birdeye, and BBB each track their own separate pools of reviews. Where sources disagreed, the number shown here is the one most directly tied to a platform's own listing rather than a third-party estimate.
