Leak detection and repair in Los Angeles

Hidden leaks waste water and cause mold and damage long before you see them. We pinpoint the leak first, so any opening in a wall or floor is small and in the right spot.

What needs fixing?

Find it first, then fix it

A leak behind a wall or under a floor can run for months. By the time a stain shows up, the drywall, framing or flooring may already be wet.

We confirm there’s a leak, figure out which line it’s on, and narrow down the exact spot. Then we make one small, targeted opening to repair it, instead of tearing out large sections.

Warm spots on the floorA sign of a hot water leak under the slab.

How we find leaks

  • A water meter test to confirm the leak and how fast it’s running.
  • Shutting off and testing sections to tell which line is leaking.
  • Leak detection equipment to locate escaping water behind walls and under floors.
  • A written price for the repair before any opening is made.
A quick check you can do

Turn off every faucet and appliance that uses water, then look at your water meter. If the small leak indicator, often a triangle or star, is still turning, water is escaping somewhere.

What affects the price

You get a written price before any work starts. These are the things that move it.

Leak detection questions

Will you have to open my walls?

We pinpoint the leak first. If we need to open a wall or floor, it’s a small opening right at the leak.

Does insurance cover leaks?

Sudden leaks are often covered, while slow, long-term leaks often aren’t. Check your policy. We can document what we find with photos for your claim.

What causes leaks in LA homes?

Corroding galvanized and copper pipes, water pressure that’s too high, worn fittings and valves, and pipes rubbing against concrete or framing.

Can a small leak wait?

A small leak can cause mold and rot over time, and it usually gets worse. It’s cheaper to fix early.
