  1. The Super Plumber - Ottawa

    urgent drain, sewer and water heater work at any hour in Ottawa4.9(478 Google reviews)1181 Parisien St Unit B, Ottawa, ON K1B 4W4, CanadaBest for urgent drain, sewer and water heater work at any hour in Ottawa    Rank01

    Why we picked them

    A 4.9 average across 478 Google reviews is the kind of number that is hard to fake and harder to maintain, and it is the strongest thing on this profile. The branch model brings real advantages, overnight dispatch and camera diagnostics among them, though it also brings advertised offers with conditions, so pin down the scope in writing before work starts. Good first call for drains, sewers and water heaters; get a second quote if the job turns into a full sewer replacement.

    What we like

    • 4.9 stars from 478 reviews on its Google Business Profile, read September 26, 2026
    • Published hours list open 24 hours, seven days a week
    • Deep drain and sewer capability, including hydro jetting, camera inspection and trenchless repair
    • Covers water treatment as well as plumbing, useful for hard water and rural wells
    • Trading since 2006 per its own website, with branches in several Canadian cities

    Things to consider

    • Advertised fixed-price offers carry conditions, so confirm what is excluded before work starts
    • Part of a multi-city operation rather than a single local owner-operator, which suits some buyers more than others
    • After-hours and emergency work typically costs more than a scheduled weekday visit
    • Licensing, insurance and warranty terms are not detailed in this profile and should be confirmed directly

    Services

    • Emergency plumbing
    • Drain cleaning
    • Repiping
    • Sewer line repair

  2. Environmental Plumbing

    drain and sewer work in older Ottawa and west end homes4.8(491 Google reviews)Best for drain and sewer work in older Ottawa and west end homes    Rank02

    Why we picked them

    The service list here is one of the most detailed we have read for an Ottawa plumber, and the specificity is a good sign: naming polybutylene, lead and cast iron separately is the kind of thing a company does when it actually performs that work. A 4.8 average across 491 Google reviews is a meaningful sample. Get the call-out and after-hours pricing in plain terms up front, since the site leads with an emergency number and a booking discount rather than rates.

    What we like

    • 4.8 from 491 reviews on its Google Business Profile as of September 27, 2026
    • Dedicated drain capability including hydrojetting and tree root removal
    • Lists polybutylene, lead and cast iron pipe replacement, relevant to older Ottawa housing
    • Covers basement water risk with backwater valves, backup sump pumps and waterproofing
    • Takes small work such as appliance and water line hookups alongside major replacements
    • Company says it was founded by a plumber with over 35 years of local experience

    Things to consider

    • No pricing, licence or insurance details published in the material reviewed, so confirm directly
    • West end base means east end callers should check response times
    • Site reads as residential throughout, with no described commercial contracting

  3. B&W Plumbing

    recurring drain and sewer trouble in older Ottawa homes, plus renovation rough-ins5.0(219 Google reviews)50 Cleopatra Dr, Ottawa, ON K2G 0B3, CanadaBest for recurring drain and sewer trouble in older Ottawa homes, plus renovation rough-ins    Rank03

    Why we picked them

    A 5.0 average across 219 Google reviews is the kind of record that is hard to manufacture, and it lines up with a small, owner-involved shop that handles a lot of repeat drain and repair work. The breadth is genuine without being overstated, covering the drain and sewer side properly while still taking renovation rough-ins. Confirm the after-hours rate and the licence details at booking, as you would with any 24/7 operation, and this is a straightforward shortlist candidate.

    What we like

    • 5.0 rating from 219 reviews on its Google Business Profile, read September 27, 2026
    • Drain and sewer depth, including camera inspection and pipe descaling
    • 24/7 scheduling published, with hours listed as open every day
    • Covers both emergency repair and planned renovation rough-in work
    • Backwater valve and backflow prevention work, relevant to Ottawa basements
    • Long list of served neighbourhoods across the city and rural edges

    Things to consider

    • Round-the-clock phone coverage is not the same as guaranteed overnight attendance; confirm the after-hours rate
    • No forced-air heating or gas work listed, only hydronic heating
    • Large commercial or multi-storey mechanical projects fall outside the advertised scope
    • Advertised seasonal discounts are time-limited, so verify what applies when you book

  4. Offset Plumbing

    overnight plumbing emergencies and older-home repairs in central Ottawa4.9(103 Google reviews)164 First Ave, Ottawa, ON K1S 2G4, CanadaBest for overnight plumbing emergencies and older-home repairs in central Ottawa    Rank04

    Why we picked them

    The combination of genuine 24/7 hours, a 4.9 rating across 103 Google reviews, and a service list that stretches from frozen pipes to septic systems and boilers gives this one unusual reach for an independent. We would go in with questions about after-hours rates and permit handling, since neither is published. The Glebe base and the emphasis on Ontario Building Code knowledge both suit Ottawa's older housing stock well.

    What we like

    • 4.9 rating from 103 reviews on its Google Business Profile, read September 27, 2026
    • Published hours show the line open 24 hours a day, every day, matching its emergency positioning
    • Unusually wide service list for a small shop, including boilers, well systems and septic systems
    • Takes both service calls and full kitchen and bathroom renovations
    • Central Glebe address, close to Ottawa's older brick housing stock
    • States its plumbers are licensed in both plumbing and gas

    Things to consider

    • No pricing, call-out fee or warranty terms are published, so ask before booking
    • Licensing and gas qualifications are the company's own claim on its website and worth confirming directly
    • A smaller independent may have less capacity than a franchise on a busy storm or freeze day

  5. Canada Plumbing

    after-hours drain and hot water emergencies in Ottawa, plus cast iron stack repairs in older homes5.0(176 Google reviews)5330 Canotek Rd Unit 22, Ottawa, ON K1J 9C1, CanadaBest for after-hours drain and hot water emergencies in Ottawa, plus cast iron stack repairs in older homes    Rank05

    Why we picked them

    A 5 rating from 176 reviews is the kind of number that deserves a second look, and in this case it sits alongside a service list with real depth on drains, cast iron and water treatment rather than a generic catch-all page. The 24/7 availability and the 30-minute commercial response are the company's own claims, so pin down after-hours rates and call-out fees on the phone before you agree to anything. For emergency drain and hot water work in Ottawa, this is a credible call.

    What we like

    • A 5 rating from 176 reviews on its Google Business Profile, read on September 27, 2026
    • Published hours show 24 hours a day, every day, including holidays
    • Named specialisms in drain cleaning and cast iron drain pipe repair, relevant to Ottawa's older housing stock
    • Water treatment work including softeners, reverse osmosis and replacement cartridges
    • Covers residential, commercial and condominium clients, with an east-end base close to Orleans

    Things to consider

    • The 30-minute response time and 24/7 availability are the company's own claims and are not independently verified
    • Two phone numbers appear on the website, so confirm which one reaches dispatch
    • No pricing, call-out fee or warranty terms are published, so ask before booking

  6. DH Plumbing & Heating

    24/7 emergency plumbing and water heater work across Ottawa's west end4.9(115 Google reviews)275 Stroget Private, Ottawa, ON K2E 0A9, CanadaBest for 24/7 emergency plumbing and water heater work across Ottawa's west end    Rank06

    Why we picked them

    A 4.9 average across 115 Google reviews is the kind of number that is hard to fake at that volume, and the service list is genuinely broad for an operation of this size, taking in boilers, gas lines and backflow testing alongside the usual drain and water heater work. The claims about licensing, insurance and upfront pricing come from the company's own site, so treat them as claims and verify them in the first call. For a mid-sized Ottawa household needing both emergency response and planned replacement, it is a sensible shortlist entry.

    What we like

    • 4.9 rating from 115 reviews on its Google Business Profile, read September 27, 2026
    • Published hours show 24 hours a day, seven days a week
    • Service range spans plumbing and heating, including boilers and gas lines
    • Backflow prevention testing offered, useful for commercial and multi-unit compliance
    • Online service request form as well as phone booking
    • Trading since 2015, per its own website

    Things to consider

    • Licensing, insurance and upfront pricing are the company's own claims and worth verifying before booking
    • After-hours and weekend call-out rates are not published, so ask for the premium up front
    • No detail published on large scale commercial mechanical work or trenchless sewer replacement

    Services

    • Emergency plumbing

  7. Its Plumbing

    well pump and water treatment work plus 24-hour emergency plumbing around Ottawa4.9(84 Google reviews)1680 Woodward Dr Unit 206, Ottawa, ON K2C 2B5, CanadaBest for well pump and water treatment work plus 24-hour emergency plumbing around Ottawa    Rank07

    Why we picked them

    The well water focus is the genuinely useful differentiator here, and paired with round-the-clock hours and a 4.9 average from 84 Google reviews it makes a reasonable shortlist candidate for anyone outside the serviced core. We would want the warranty terms, the licence numbers and the flat-rate promise written onto the estimate before signing, mostly because the website leaves those points general. The placeholder text still sitting in the site's testimonials section is a small thing, but it is the kind of detail that makes a reader wonder what else has not been finished.

    What we like

    • 4.9 average from 84 Google reviews, read on September 27, 2026
    • Well pumps, pressure tanks, water testing and treatment handled alongside standard plumbing
    • Published hours show 24 hours a day, seven days a week
    • Plumbing, heating and cooling all listed, so one contractor can cover several systems
    • Stated service area reaches Arnprior, Carleton Place, Kemptville and Rockland
    • Company states work is done by a licensed plumber and gas fitter, with flat-rate emergency pricing

    Things to consider

    • Warranty and satisfaction guarantee are advertised but the terms and duration are not published
    • The website still shows placeholder text in its testimonials section
    • The postal code on the site differs from the one on the Google listing, so confirm the address if visiting
    • No evidence in the brief of large-scale commercial or new-build mechanical work

  8. John The Plumber & Drain Cleaning

    recurring drain and sewer backups in older Ottawa homes4.9(421 Google reviews)2688 Conn St, Ottawa, ON K2B 7C7, CanadaBest for recurring drain and sewer backups in older Ottawa homes    Rank08

    Why we picked them

    The drainage-first positioning is genuine rather than cosmetic, and the willingness to say hydro jetting is not right for every pipe is the sort of caveat you rarely see on a plumbing site. A 4.9 average across 421 Google reviews is solid evidence of consistent residential work. We would still get the price in writing before the equipment comes off the truck, and read the monthly payment program closely before signing.

    What we like

    • 4.9 rating from 421 Google reviews as read on September 27, 2026
    • Published hours show 24 hours a day, seven days a week
    • Genuine drain and sewer specialism, including camera inspections and root removal
    • Backwater valve inspection, service and installation, relevant to Ottawa's flood-prone basements
    • Trading in Ottawa since 2006 per its own website
    • Covers the west end plus Kanata, Barrhaven, Nepean, Orleans and downtown

    Things to consider

    • Pricing is not published, so get the quote in writing before work begins
    • After-hours call-out costs are not stated despite the 24-hour listing
    • Positioned around drains and sewers rather than large commercial or new-build projects
    • The monthly payment program's coverage and cancellation terms need checking before you sign

This list was assembled from Google Maps results for the trade and city, then each company was written up from its own public profile. Positions follow Google's order and are not an editorial judgement until an editor reviews them.

How to choose a plumber in Ottawa

  • Verify insurance and credentials

    Ask for a current certificate of insurance and confirm registration or licensing with the authority that issues it, not with the company.

  • Ask for a written estimate

    Scope, materials, removal, disposal and who pulls the permit should all be named on the page rather than agreed on the doorstep.

  • Compare multiple quotes

    Two or three bids on the same scope. A number far below the others usually means something has been left out of it.

  • Understand the warranty

    Separate the manufacturer's warranty on materials from the company's own warranty on the work, and get both in writing.

  • Ask who performs the work

    Find out whether the crew are employees or subcontractors, and who supervises them on the day.

  • Check recent local projects

    Ask for addresses or photographs of comparable jobs finished nearby in the last year or two.

  • Avoid high-pressure sales

    A discount that expires today, or a knock on the door after a storm, is a reason to slow down rather than sign.

  • Get everything in writing

    Change orders, timeline and payment schedule included, before the first payment changes hands.

Questions to ask before hiring

  • Are you insured, and can you send the certificate?
  • How long have you worked in this area?
  • Will you provide a written estimate with materials listed?
  • What warranty do you offer on the work itself?
  • Do you use subcontractors for this job?
  • Who handles permits and inspection?
  • What would you recommend here, and why?
  • How are unexpected costs handled once work starts?
  • What is the estimated timeline from start to finish?
  • Can you provide recent local references?

Red flags

  • No verifiable local business address or registration
  • Pressure to sign on the first visit
  • A demand for full payment up front
  • An offer to cover or waive your insurance deductible
  • Refusal to put warranty terms in writing
  • A quote that will not itemize scope
