Plumbing services for Ontario homes
Everyday repairs
From everyday clogs and fixture repairs to stuck disposals, we restore kitchens and baths with drain cleaning, toilet and faucet repair, and garbage disposal service.
Water heaters
No hot water, lukewarm showers, or a leaking tank get a clear repair-versus-replace plan — tank-body leaks usually mean replace; a failed control or element on a younger unit is often worth repairing. Our water heater team diagnoses on site.
Leaks and lines
We trace hidden drips with leak detection, repair gas lines, and correct low pressure with water pressure regulator work when that is the cause.
Sewer and repiping
Stubborn lines may need camera inspection, hydro jetting, or trenchless sewer repair. Homes with aging pipes can move to whole-house repiping. See our plumbing overview for the full range.
Tell us what is going on at the house.

Estimates stay valid for 14 days. All HVAC estimates are free. The $59 HVAC repair diagnostic is waived when you approve the repair. Furnace and AC tune-ups are $99 each.
