Plumbers in Durham Region

Plumbing pricing splits into two models: a flat rate per job, or a service call fee plus hourly. Flat rate is usually better for you on straightforward work because the risk of a slow day sits with the contractor. Ask which model you are being quoted under before comparing two numbers.

Job	Typical range
Service call / diagnostic visitOften credited against the repair if you proceed. Ask whether it is.	$90 – $180
Hourly rate (after the call-out)Higher end for emergency, evening and weekend work.	$95 – $175 / hour
Clear a blocked drainSnaking a simple clog sits at the low end; hydro-jetting or a camera inspection pushes it up.	$150 – $450
Replace a toiletIncludes a mid-range fixture and removal of the old one.	$350 – $800
Water heater replacement (tank, gas)Installed and vented. Rental buyouts are separate - check who owns your current tank.	$1,800 – $3,200
Tankless water heater conversionHigher because it usually needs new venting and a gas line upsize.	$4,000 – $7,000
Sump pump supply and installBattery backup adds roughly $600 to $1,200.	$700 – $1,800
Repipe a typical house in PEXDepends heavily on how much drywall has to come out and go back.	$6,000 – $15,000

Questions to ask before you hire

Is the person doing the work certified in 306A, or an apprentice being supervised? Both are fine. You just want to know.

Is this quote flat rate or time and materials? If hourly, what is the estimated range and what happens if it runs over?

Does the job touch a gas line, and if so who holds the TSSA certificate?

Does this need a municipal plumbing permit, and are you pulling it?

What is the warranty on labour, separately from the manufacturer warranty on parts?

If you open a wall to reach the pipe, is patching and painting included or is that on me?

Warning signs

A quote given over the phone for work nobody has looked at, on anything more involved than a fixture swap.

Reluctance to give a certificate number when asked directly. Certified plumbers are used to this question.

Pressure to decide immediately because of a "crew in the area today".

Cash-only pricing framed as a discount. You lose your warranty, your paper trail, and your recourse.
