Licensed, Insured Pros Quoted Before Work Starts Emergency & Scheduled Service Serving All San Diego County

A hidden leak, water or gas, is one of the most damaging problems a homeowner can face. Water silently soaking into walls, subfloors, and foundations can cause structural damage, toxic mold growth, and catastrophically high water bills. Gas leaks are even more dangerous, undetected natural gas buildup creates explosion and carbon monoxide risks. San Diego homes, particularly those with slab foundations common in the region, are prone to slab leaks where water lines buried in or under the concrete develop pinhole leaks from corrosion. Plumbing Pro San Diego uses electronic leak detection, thermal imaging, gas sniffers, and pressure testing to find both water and gas leaks precisely before opening any walls or floors.

Frequently Asked Questions

Common questions about leak detection services in San Diego.

How do I know if I have a hidden water leak?

Signs include a water bill that's higher than usual with no change in usage, the sound of running water when all fixtures are off, warm spots on floors (indicating a hot water slab leak), wet or discolored walls or ceilings, mold or musty smells, and dropping water pressure.

What is a slab leak?

A slab leak is a leak in the water lines running through or under your concrete foundation. They're common in San Diego homes built in the older because the copper pipes from that era are now corroding. Slab leaks can cause foundation damage if left unaddressed.

How much does leak detection cost in San Diego?

Leak detection cost depends on how extensive the search is and where the suspected leak is located. If the plumbers we connect you with perform the repair, the detection cost is often applied toward the total. Finding a leak precisely costs far less than the water damage from opening the wrong wall.

Can a leak detection plumber find pool leaks?

Yes. The plumbers we connect you with use dye testing, pressure testing, and acoustic equipment to locate leaks in pool plumbing lines and shells.

How do I turn off my water if I suspect a slab leak?

Locate your main water shutoff valve, usually near the front of your home by the meter, and turn it clockwise to close. Then call us immediately. The sooner a slab leak is stopped, the less structural damage results.

Do you offer gas leak detection service?

Yes. The plumbers we connect you with use combustible gas detectors and pressure testing to locate gas leaks in supply lines, fittings, and appliance connections. Gas leak detection cost depends on how many potential leak points need to be checked. If you smell rotten eggs (mercaptan), leave the house immediately and call SDG&E at 1-800-411-7343, and we'll connect you with a plumber for the repair.

What are the signs of a gas leak in my house?

The most obvious sign is the smell of rotten eggs, natural gas has mercaptan added as a safety odorant. Other signs include a hissing sound near gas lines or appliances, dead vegetation near a gas line path, higher-than-expected gas bills, and physical symptoms like headaches, nausea, or dizziness.
