Need a plumber in Cornwall or Eastern Ontario? SOS Canada Plumbing & Heating is locally based and serves Cornwall, Long Sault, Morrisburg, Ingleside, Alexandria, and Hawkesbury. Residential repairs, renovations, drain cleaning, water heater installation, and 24/7 emergency response — all from one licensed, bilingual team.
From routine maintenance to full-scale renovations and emergency interventions, SOS Canada Plumbing & Heating provides complete plumbing services for homes and businesses throughout the Cornwall region.
Burst pipe, sewer backup, flooded basement or gas leak? Our emergency line is answered around the clock, every day of the year. We dispatch a licensed technician as quickly as possible with the tools to stop water damage in its tracks. Shutting off your main water valve while waiting for us can significantly reduce damage — it is usually located in the basement near the front wall of the house.
Much of Cornwall's residential housing was built between 1930 and 1970 with galvanized steel supply pipes that corrode from the inside, reducing water pressure and contaminating water with rust. We inspect, diagnose, and replace aging pipes with modern copper or cross-linked polyethylene (PEX) — a durable, freeze-resistant alternative that is particularly suited to Eastern Ontario winters.
Slow drains, gurgling toilets, and sewage odours are early signs of a blocked drain. We use high-pressure hydro jetting to clear grease, roots, and mineral buildup from drains without damaging the pipe. For recurring blockages, a camera inspection pinpoints the exact cause — root intrusion, pipe collapse, or offset joints — so the fix is permanent rather than temporary.
We serve homeowners and businesses in the smaller communities along the St. Lawrence: Long Sault, Morrisburg, Ingleside, Iroquois, and Williamsburg. Rural properties sometimes combine municipal water with private septic systems, which require specific expertise. Our team handles both sides of the equation — from water supply issues to septic-connected drain problems.
We supply and install all major types of water heaters in Cornwall and Eastern Ontario: electric storage tanks, natural gas units, and tankless (on-demand) systems. Tankless water heaters are increasingly popular in the region for their energy efficiency and continuous hot water supply. Emergency replacements are available 7 days a week — no cold showers longer than necessary.

Many Cornwall homes built between 1920 and 1970 have galvanized steel supply pipes with reduced flow, clay sewer drains susceptible to root intrusion, cracking cast iron drain stacks, and outdated fixtures. A camera inspection is the most efficient way to assess the real condition of your plumbing before deciding on repairs.
