Older supply-line joints seep behind sinks and basement ceilings
Why it happens here
Historic homes may have several generations of pipe and fittings joined together. Vibration, corrosion, or a worn seal can cause a slow leak that travels along a pipe before reaching a cabinet or ceiling. Older shutoffs can also fail to close fully.
Our approach
We trace moisture back to the source, isolate the line, and identify the material before removing a fitting. We replace the failed connection with a compatible part, inspect nearby joints, and test under pressure. That helps prevent a new drip just beyond the repair.
