Frequently Asked Questions

What types of plumbing work require a permit in Ontario?

New drain lines, water service upgrades, and rough-in work for new fixtures typically require a permit under the Ontario Building Code. Your plumber should apply for the permit - ask them to confirm requirements before work starts.

How do I know if my water heater needs replacing?

Most conventional tank water heaters last 8-12 years. Signs of failure include rust in the water, inconsistent temperatures, visible corrosion on the tank, or pooling water near the unit. A plumber can assess whether repair or replacement makes more sense for your situation.

What is backflow prevention and do I need it?

A backflow preventer stops contaminated water from flowing back into the municipal supply. Many Ontario municipalities require them on irrigation systems and in properties where chemical fertilizers are used. A plumber can assess your home's requirements during an inspection.

How much does a plumber cost in Ontario?

Most Ontario plumbers charge $100-$200 per hour plus materials during standard hours. After-hours emergency service typically runs $200-$400 per hour. For larger jobs like bathroom rough-ins or water service replacements, ask for a fixed-price quote rather than an hourly estimate.

When is the best time to address plumbing repairs in Ontario?

Plumbing repairs should be addressed as soon as a problem is noticed - leaks and drain issues worsen quickly and can cause water damage. Planned work like water heater replacements or bathroom rough-ins can be scheduled in any season. Outdoor irrigation and hose bib work is best done in spring before freeze risk.

What should I ask a plumber before hiring them in Ontario?

Ask whether they will pull the required permits, how they price the job (hourly vs. fixed), their response time for emergencies, and whether they offer a warranty on labour. For larger jobs, request a written scope of work before work begins.
