Why Slab Leaks Are Common in San Antonio
San Antonio sits on expansive clay soil that shifts with moisture changes. This soil movement puts stress on the pipes running under your foundation, causing joints to separate and copper pipes to develop pinhole leaks. Combined with San Antonio's hard water, which accelerates pipe corrosion, slab leaks are one of the most common plumbing issues in the area. If you have a slab leak, a water softener can help prevent future corrosion. Homes with galvanized or copper pipes older than 30 years may benefit from whole-house repiping to PEX, which is more resistant to both corrosion and soil movement.
When Slab Leaks Cause Bigger Problems
Undetected slab leaks can cause serious water damage including warped flooring, mold growth, and foundation damage. If a slab leak has already caused damage, C.S.W. Power Solutions handles the full restoration as a licensed general contractor — including insurance claim coordination. Our leak detection services can identify hidden leaks before they become emergencies.
