Slab leaks in 1970s and 1980s homes
Why it happens here
The copper supply lines under West Haven slabs have been under pressure for decades. The soil in this area can be slightly acidic, which slowly corrodes the pipe from the outside. Pinhole leaks form, and water starts pooling under the slab. You may not see it until the floor is warm or the bill spikes.
Our approach
We use acoustic listening and thermal imaging to find the leak without breaking up the whole floor. Then we cut out the damaged section and replace it with new copper or PEX. We pressure-test the repair and check the rest of the line for weak spots.
