Hidden water leaks are a silent threat to Fresno homes and businesses. Whether it's a pinhole leak in a copper supply line, a slow drip behind a bathroom wall, or a slab leak running beneath a concrete foundation, undetected leaks drive up water bills, promote mold growth, and cause structural damage over time. 1st Fresno Plumbing uses pressure testing and acoustic listening equipment to pinpoint leak locations with minimal guesswork and minimal destruction to your property.
Once the leak is located, our technicians perform durable repairs using code-compliant materials and proper fittings — not just temporary patches. We handle everything from simple compression fitting replacements on exposed supply lines to re-routing sections of copper or PEX pipe to bypass a corroded or repeatedly failing segment. All repair work is done with the goal of preventing the same issue from recurring.
Fresno's aging housing stock and mineral-rich water supply make pipe corrosion and joint failures more common than many homeowners realize. If your water bill has unexpectedly climbed or you notice warm spots on your floor, staining on walls, or the sound of running water when fixtures are off, call 1st Fresno Plumbing at (559) 744-0700 right away for same-week diagnostic service.
