From a toilet that will not stop running to pinhole leaks in copper under the floor, our team has the know-how and the tools to find the leak and stop it.
Leak detection and repair covers everything from the obvious, such as a dripping faucet or a toilet that will not stop running, to hidden leaks in supply pipes behind walls and under floors. Hayes Plumbing finds the source, repairs it and, when copper lines have started developing pinholes, explains when repiping makes more sense than fixing one leak after another.

Common questions about leak detection & repair in Oshawa and Durham Region.
Turn off every fixture and appliance and watch the water meter. If it keeps moving, water is escaping somewhere. Unexplained bill increases, damp drywall and the sound of running water are the other common signs.
