Accurate Water Leak Detection in San Francisco

Heise's Plumbing offers advanced water leak detection services in San Francisco, CA, to prevent quiet water damage and lower utility bills. Using state-of-the-art acoustic equipment and thermal imaging, our licensed technicians locate hidden leaks in walls, ceilings, and under concrete slabs. We identify the precise source of the leak and complete high-quality, long-lasting copper or PEX pipe repairs with minimal disruption.

Common Problems We Resolve

• Unexplained water bill spikes suggesting hidden pipe leaks.
• Water spots, mold growth, or buckling hardwood floors.
• Slab leaks under concrete foundations causing damp spots or warmth.

How We Diagnose & Solve the Issue

Inspection & Diagnosis: We pressurize the water system, perform acoustic pipe listening tests, use thermal cameras to map temperature spikes behind drywall, and isolate the exact leak source.

Our Service Process: We locate the leak, provide repair solutions (such as spot replacement or repiping), complete clean, code-compliant line fixes, and test the entire system to ensure it is 100% dry.

Local Considerations in San Francisco

Historic San Francisco properties often have old plaster walls and subfloors. Non-destructive acoustic testing is vital to locate leaks before tearing into fine lath-and-plaster or heritage woodwork.
