Water Pipe Repair
Bay Area's #1 Choice

Most failures are caused by internal corrosion (pitting), high water pressure exceeding 80 PSI, or thermal expansion. In older homes, galvanized steel pipes rust from the inside out, while copper pipes can develop pinhole leaks due to aggressive water chemistry. Ground shifting and tree root intrusion are the primary causes for underground main line breaks.

A localized repair for an accessible pipe typically ranges from $250 to $600. If the leak is behind a wall or under a slab, costs increase to $500–$1,500 due to the labor required for access and subsequent restoration. Main water line repairs involving excavation generally average around $1,000 to $2,000.

The most common sign is the appearance of small, green or blue green "crusty" deposits on the exterior of the pipe. These are called tubercles and indicate that a pinhole leak has already formed. If you see multiple green spots, the pipe wall has likely thinned systemically and may require a section replacement rather than a simple patch.

System-wide pressure loss usually indicates a breach in the main water service line or a failing Pressure Regulator Valve (PRV). If a pipe has burst underground, water is escaping before it reaches your fixtures. We test the pressure at the main entry point to determine if the issue is a mechanical valve failure or a structural pipe break.

If the leak is caused by a mechanical "nick" or a single failed joint, a patch is sufficient. However, if the leak is caused by corrosion or age, patching one spot often leads to another leak nearby because the rest of the pipe is equally thin. In these cases, replacing the entire run is the more cost-effective way to prevent recurring water damage.

Yes. We can install a new line by only digging two small access points, preserving your driveway and landscaping while providing a seamless, high-durability replacement.

Most interior pipe repairs are completed within 2 to 4 hours. Underground main line repairs usually take a full day, especially if excavation and municipal inspections are required. We prioritize restoring your water service as quickly as possible, typically within the same day of the service call.

When a system is shut down and restarted, the change in pressure can dislodge harmless mineral sediment or oxidized iron from the inside of older pipes. Running your cold water taps for a few minutes will usually clear the lines. If the discoloration persists, it may indicate systemic corrosion that requires further investigation.

Yes. Any pressure over 80 PSI puts excessive stress on pipe joints, valves, and appliance hoses. This leads to "water hammer" (banging sounds) and premature pipe failure. We install and calibrate Pressure Regulator Valves (PRV) to keep your home within the safe 50-70 PSI range.

Yes. A burst pipe can cause thousands of dollars in damage within minutes. We offer 24/7 emergency response to isolate the leak, perform the necessary repairs, and ensure your home's water system is safe and functional, regardless of the time of day.
