Water & Gas Leak Detection in San Diego — Find Hidden Leaks Without the Demolition
Advanced equipment pinpoints water and gas leaks behind walls, under slabs, and underground — before they cause serious damage.
A hidden leak — water or gas — is one of the most damaging problems a homeowner can face. Water silently soaking into walls, subfloors, and foundations can cause structural damage, toxic mold growth, and catastrophically high water bills. Gas leaks are even more dangerous — undetected natural gas buildup creates explosion and carbon monoxide risks. San Diego homes — particularly those with slab foundations common in the region — are prone to slab leaks where water lines buried in or under the concrete develop pinhole leaks from corrosion. Plumbing Pro San Diego uses electronic leak detection, thermal imaging, gas sniffers, and pressure testing to find both water and gas leaks precisely before opening any walls or floors.
