Galvanized supply lines failing inside walls
Why it happens here
Homes built before 1960 in North Winnetka still have galvanized steel pipes. They corrode from the inside out and eventually pinhole or burst, usually inside a wall where you can't see the leak until damage spreads.
Our approach
We use thermal imaging to find the leak without tearing out the whole wall. Then we repair the line, extract water from the cavity, and dry the plaster and framing. We also flag other sections of the same pipe that are likely to fail.
