Cold Water Slab Leak Repair in South San Francisco
Cold water slab leaks are harder to feel but still waste water and wet the soil. They often show up as a high water bill or a meter that moves with all fixtures off. We isolate the cold line, find the leak and repair or reroute it. Fixing cold leaks quickly helps protect your foundation.

Spot Repair Through the Slab in South San Francisco, CA
When the leak is isolated and the rest of the pipe is in good shape, a spot repair through the slab is a sensible option. We cut a small opening, excavate to the pipe and replace the damaged section. The trench is compacted and the concrete is patched. Flooring is then restored by your preferred contractor.
Advanced Leak Detection Technology in South San Francisco
Our commitment to effective slab leak repair includes investing in the latest diagnostic technology. We use equipment such as thermal imaging cameras to detect temperature changes caused by leaking hot water lines, and very sensitive acoustic sensors to listen for the sound of escaping water. This technology lets us locate leaks without guesswork, even in the diverse mix of buildings across South San Francisco.
Slab Leak Reroute in South San Francisco
Rerouting is often the best long-term choice, especially with older copper lines. We abandon the leaking line under the slab and run a new PEX line through the attic and walls. Openings are small and placed where patching is simplest. Reroutes end future leaks in that section of pipe.
Sewer Line Slab Leak Repair in South San Francisco, CA
Slab leaks aren't always about clean water pipes, since sewer lines can also leak under your foundation. These leaks pose serious health risks and can cause extensive damage.

Our methods restore proper waste removal and prevent contamination in your South San Francisco, CA property, following health and safety codes.

Frequently Asked Questions About Slab Leak Repair in South San Francisco
The cost of slab leak repair in South San Francisco can range from $500 for a simple, accessible repair to $5,000 or more for complex rerouting or extensive repiping. Factors include leak location, pipe type, repair method, and needed restoration work. We provide a detailed estimate after our initial leak detection.
Simple spot repairs often do not need a permit, but reroutes and repipes may, depending on your city. We take care of permits when required.
While not entirely preventable, regular plumbing inspections can help identify potential issues early. Using quality plumbing materials during construction or repiping, and checking any noticeable water pressure changes promptly, can help reduce the risk of slab leaks in your South San Francisco home.
Common causes include corrosion from hard water, abrasion where pipes rub against concrete or gravel, poor installation, high water pressure and soil movement. Hot water lines are especially vulnerable.
Look for unexplained spikes in your water bill, warm spots on your floor, the sound of running water when no fixtures are in use, visible water stains or mildew on baseboards or carpets, and cracks in your foundation. These are clear indicators that you might have a hidden slab leak in your South San Francisco home.
