Hot Water Slab Leak Detection in Kalispell
Hot water lines leak under slabs more often than cold lines because heat speeds up corrosion and causes expansion and contraction. Signs include warm spots on the floor, a water heater that runs constantly and higher gas or electric bills. Thermal imaging shows the heat pattern spreading through tile or concrete. We confirm with a pressure test and acoustic listening before flagging the spot.
Cold Water Slab Leak Detection in Kalispell, MT
Cold water slab leaks do not create warm spots, so they are more difficult to see. They often show up as a running water meter, damp carpet, a musty smell or water seeping at baseboards. We isolate the cold side and use acoustic equipment to listen for the leak through the slab. Line tracers map the pipe route so we know where to listen.
