Water Leak Repair in Ontario: Frequently Asked Questions
How do I know if I have a hidden water leak?
Check your water meter with everything off; if it still moves, you have a leak. High bills, damp smells and warm floor spots are other signs we see constantly in Ontario.

A slow leak in Ontario can ruin drywall, framing and flooring within days and feed mold growth. Fixing it early is far cheaper.
