Find it first, then open
A high water bill, a damp patch, a stain downstairs. We locate the leak precisely so only a small area is opened.
Locating the Leak
Circuit by circuit, then the exact spot.
We check the meter and the visible fittings first, then test the hot and cold circuits separately to find the one losing water, and narrow down the position before opening.
- Meter test
- Circuit testing
- Position narrowed down
- One small opening
Repair and Retest
Fixed, pressure-tested, closed.
Once found, you get the price of the repair. After fixing it we test the circuit again so you know it holds.
