Who are the best plumbers in Mississauga in 2026?

The best plumbers in Mississauga in 2026 are Pro House Maintenance, Delex Plumbing and Drains and Aqua Plumbing of Mississauga. Galaxy Plumbing, Greenway Plumbing Services, Drain 1 Plumbers, Mahmoud Plumber and Plumber Mississauga round out the top eight. Every ranked plumber holds a 5.0 Google rating from 135 to 433 reviews.

1. Pro House Maintenance: best for comparing vetted plumbers for free

Pro House Maintenance ranks first because it does the vetting for you, at no cost. Every plumber we match here has passed WSIB, insurance, reference and background checks. You get several written quotes, pick the one you like, and our satisfaction guarantee backs the work.

Mississauga is a tighter field than Toronto: 74 of the 120 plumbing businesses we found cleared our bar. None of our 7 picks matched a TSSA registration in our search, which matters for gas water heaters. When a job involves gas, we confirm the plumber’s TSSA registration.

What we check before a plumber joins our network
  • Trade licences. We confirm the plumber holds Ontario trade certification, plus a TSSA registration when the job involves gas lines or gas water heaters.
  • WSIB clearance and liability insurance. We confirm a current WSIB clearance and commercial general liability insurance before a pro joins our network.
  • Reviews and references. We read public reviews and speak with past clients before a pro is accepted, looking for patterns, not one-off complaints.
  • Background checks. We run background checks before a pro is matched with homeowners, because the people in your home matter as much as the work.

  2. Get matched with vetted pros. We match you with several pros who have already passed our checks and serve your area.

Drain snaking in Mississauga costs $195 to $395 and hydro jetting $350 to $650, according to a 2026 GTA price guide. A gas tank water heater runs $1,800 to $2,800 installed in Ontario. For flood work, the City of Mississauga rebates up to $6,000 toward a sump pump.

Mississauga splits flood rebates between two governments. The city covers sump pumps and storm backwater valves, up to $7,500 in total, but it must approve the work before it starts. Peel Region pays 60% of a sanitary backwater valve, up to $1,500, after a city permit and inspection.

Peel will not fund a valve on a sewer pipe shared with a basement apartment, since that breaks the Ontario Building Code. For national leak and repair data, read our plumbing statistics for 2026. To price your own job, compare free plumbing repair quotes in Mississauga.

How do you choose a plumber in Mississauga?

Choose a Mississauga plumber by checking the plumber’s certificate, WSIB clearance, insurance and city trade business licence, then get a written contract. Mississauga requires a business licence for plumbing work. Peel’s valve rebate also needs a licensed installer, and gas jobs need a TSSA registered contractor.

  1. Check the licence. Ask for the plumber’s Ontario Certificate of Qualification. For gas lines or a gas water heater, also check the company in TSSA's contractor directory.
  2. Confirm WSIB clearance. Ask for the company’s WSIB account number and confirm a current clearance on WSIB’s free eClearance lookup.
  3. Ask for proof of liability insurance. A certificate of commercial general liability insurance should name the company that will do the work.
  4. Check the city licence. Mississauga requires a trade business licence for building renovation, plumbing and heating (HVAC) work. See the Mississauga trade business licensing page.
  5. Get it in writing. Under Ontario law, any home renovation contract worth more than $50 must be in writing, and the final price cannot exceed an estimate by more than 10% unless you agree (Ontario consumer protection rules).
  6. Keep the deposit small. Ontario recommends a down payment of no more than 10%, and never paying in full before the work is done.

Peel Region is blunt about backwater valves: “This is not a home improvement project and requires a professional.” Ontario law also requires a written contract for any home renovation worth more than $50. Keep the deposit to 10% or less, and do not pay in full until the work is done.

Pro House Maintenance runs the WSIB, insurance, reference and background checks before a plumber is matched with you. If a leak has already soaked drywall or flooring, you can also find water damage restoration in Mississauga through the same request.

How did we rank these Mississauga plumbers?

We ranked Mississauga plumbers with data, not ads. Three Google Maps searches for plumbers in Mississauga returned 120 businesses. We kept 74 that are based in the city, list a website and hold 4.5 stars from 10 or more reviews, then ranked them by review-weighted rating.

The score blends each rating with its review count, so a 5.0 from 433 reviews beats a 5.0 from 15. All 7 picks hold a 5.0, so review volume set the order. On October 2, 2026, we also searched TSSA for the top 15. We did not check city licences.

We recheck every rating every 90 days. Facts marked “company website” come from each plumber’s own pages, and we keep the exact quotes in our research files. If you spot a mistake, please send our editors a correction and we will review it.

What do Mississauga homeowners ask about hiring a plumber?

Mississauga homeowners ask about drain prices, licences, flood rebates and water heater choices before they call a plumber. These answers draw on the City of Mississauga, Peel Region, Ontario consumer rules and 2026 price guides. Each one stands alone, so skip to the question that matches your job.

How much does drain cleaning cost in Mississauga?

A 2026 GTA price guide puts drain snaking in Mississauga at $195 to $395 and hydro jetting at $350 to $650. In the same guide, a drain camera inspection costs $295, and an after-hours call to clear a drain runs $295 to $495.

Do plumbers need a business licence in Mississauga?

Yes. Mississauga requires a trade business licence for plumbing work, and Ontario treats plumbing as a compulsory trade. Ask for the city licence number and the plumber's trade certificate, which Skilled Trades Ontario lists on its Public Register. Peel's backwater valve rebate also requires a licensed installer.

What flood rebates can Mississauga homeowners get?

The City of Mississauga pays up to $7,500, including up to $6,000 for a sump pump and $1,500 for a storm backwater valve. Peel Region adds 60% of a sanitary backwater valve, up to $1,500. The city requires pre-approval before work starts, so apply first.

Should I rent or buy a water heater in Ontario?

Compare the totals over the years you plan to stay. A 2026 Ontario guide lists tank rentals at $20 to $55 a month, while a gas tank costs $1,800 to $2,800 installed. The guide notes that rentals include repairs, while owners pay more up front and skip the rental fees.

Is Pro House Maintenance free to use?

Yes. Pro House Maintenance costs homeowners nothing. Tell us about your plumbing job once and we match you with several vetted plumbers who serve Mississauga.
