About All Flow Plumbing in San Mateo, CA

Signs of a slab leak include unexplained increases in your water bill, the sound of running water when fixtures are off, warm spots on your floor, or cracks in walls and flooring. For copper pipe corrosion, look for discolored (blue-green) water, low water pressure, or pinprick leaks. As a local San Mateo plumber, we recommend a professional plumbing inspection at the first sign of trouble, as both issues are common here and can cause significant structural damage if left untreated.

Our slab leak repair process prioritizes minimizing disruption. First, we use electronic amplification equipment to pinpoint the exact leak location. For many San Mateo homes, we can then perform a trenchless repair by accessing the pipe through a small hole in your slab, eliminating the need for major excavation. We repair or replace the damaged section with durable, corrosion-resistant materials suited for our local soil conditions. Our goal is a permanent fix that protects your foundation and gets your water service back to normal quickly.

The best solution depends on the extent of the corrosion. During a plumbing inspection, we assess the condition of your entire system. For isolated issues, a spot repair or pipe rerouting might be sufficient. However, widespread pinhole leaks—a frequent problem with aging copper pipes in San Mateo—often indicate it's more cost-effective and reliable in the long term to replace the main supply lines. We can discuss options like copper, PEX, or CPVC, balancing upfront cost with longevity to prevent future water damage and repairs.
