Where Treasure Valley homes leak
Housing age tells us a lot before we arrive. In the pre-1960s homes of Boise’s North End and East End, and in older Nampa and Caldwell, galvanized steel supply lines corrode from the inside until pinholes open, usually at threaded joints. In the slab-on-grade homes common on the Bench and in 1970s and 1980s subdivisions, copper lines run under the concrete and fail where they rub against the slab or where soil chemistry eats the pipe. In homes with crawl spaces, the risk is freezing: a supply line near a vent can split in a cold snap and leak unnoticed until spring.
Newer homes in Meridian, Eagle and Kuna are mostly PEX, which handles freezing better, but we still see leaks at fittings, at the manifold, and where a nail or screw found the pipe during construction and only now rusted through.
How we locate a leak
We start at the meter to confirm there is a leak and estimate its size, then isolate it to hot or cold, supply or drain. Acoustic equipment lets us hear pressurized water escaping through concrete or soil; a thermal camera shows hot-water leaks as a warm patch on the floor; tracer gas and pressure tests handle the stubborn ones. The result is a marked spot a foot or two across rather than a trench across the living room.
The repair
Most repairs are a straightforward section replacement in copper or PEX. For slab leaks we discuss reroute versus direct repair and quote both. For underground service lines we can often pull a new line through the old path with minimal digging. Every leak repair is pressure-tested before we close up, and the invoice includes photos of the failure so you know exactly what was wrong.
