Buyer guide

Hiring a plumber in Ottawa

What separates a great plumber from a cheap quote, and the questions worth asking before you sign.

  • Confirm the licence and insurance

    Plumbing is a licensed trade in Ontario. Ask for the licence number and confirm liability insurance before any work starts, especially for gas water heaters.

  • Ask how they price

    Some plumbers charge flat-rate per job, others by the hour plus parts. Ask which, and get any diagnostic or trip fee confirmed before they arrive.

  • Deal with a sump pump before spring

    Ottawa's spring melt tests every sump pump. Have yours checked, and ask about a battery backup so it keeps running through a power outage.

  • Know your main shutoff

    Before any emergency, have the plumber show you where the main water shutoff is. Knowing it can save your home from a burst-pipe flood.

Common questions

Plumbers in Ottawa, answered

Do Ottawa plumbers need a licence?
Yes. Plumbing in Ontario is a licensed trade. Ask for the licence number and confirm liability insurance before any work starts.
How much does a plumber cost in Ottawa?
Many Ottawa plumbers charge a service call fee plus an hourly or flat rate, with common repairs landing in the low hundreds. Emergency and after-hours calls cost more; confirm rates before they come.
How do I stop pipes from freezing in winter?
Keep the heat on, insulate pipes in unheated spaces, let a tap trickle on the coldest nights, and disconnect outdoor hoses in fall. If a pipe freezes, shut off the water and call a plumber before it thaws and bursts.
How long does a water heater last in Ottawa?
A conventional tank water heater lasts about 8 to 12 years. If yours is leaking or near that age, replace it before it fails and floods; ask about tankless as an option.
Why does my drain keep clogging?
Recurring clogs often mean grease buildup, tree roots in the line, or a venting issue rather than a one-off blockage. A plumber can camera the line to find the real cause instead of just snaking it again.
