Slab leaks in pre-1960s apartment buildings
Why it happens here
The older buildings across 91601 and 91602 were built with galvanized supply lines and original slabs. Decades of soil movement and water hardness wear those lines down. A slab leak can run for weeks before it surfaces as a warm spot on the floor or a jump in the water bill.
Our approach
We run a hydrostatic pressure test kit and an inspection camera to confirm the leak location before we open anything. That keeps us from cutting into a slab in the wrong place, and it gives the building owner a clear record for the repair.
