When you have water leaking behind a wall in Waterloo, the damp spot on the paint is only where the water finally surfaced. Behind the drywall, moisture has been soaking studs, insulation, and wiring, and mould can start within days. The source is usually a failing supply line, a corroded fitting, or a joint in a pipe run you cannot reach without opening the wall. Flowline Plumbers tracks the leak to the exact pipe and repairs it before the damage spreads through the whole cavity.
A wall leak hides its origin because water runs downhill and along framing before it shows on the surface. We use leak detection to locate the exact pipe or fitting behind the wall, then open only what we need to reach it. After the repair, we confirm the leak is fully stopped and leave you with a clear picture of any drywall work still required.
