Water stain on the ceiling? Musty smell you can’t place? A water bill that suddenly jumped? A hidden leak is already doing damage behind your walls, under your floors, or above your ceiling. The longer it runs, the bigger the repair. ASAP Water Damage Restoration Los Angeles finds the source fast, without tearing your home apart, and stops the damage before it spreads.

Call (323) 677-2811 24/7 for leak detection anywhere in Los Angeles.

Signs You Have a Hidden Water Leak

  • Brown or yellow stains on ceilings or walls
  • Paint that bubbles, peels, or feels soft
  • Warped, cupped, or lifting floors
  • A musty or earthy odor that won’t go away
  • Mold spots in corners, closets, or behind furniture
  • A higher water bill with no change in use
  • The sound of running water when every fixture is off
  • Warm spots on the floor (a common slab leak sign)

If you notice even one of these, schedule an inspection. Small leaks rarely fix themselves.

How We Find Leaks Without Demolition

Our IICRC-certified technicians use non-invasive tools to trace moisture to its source:

  • Thermal imaging: infrared cameras reveal temperature differences caused by wet materials behind drywall, under flooring, and inside ceilings.
  • Moisture meters: pin and pinless meters measure exactly how wet each surface is, so we can map the full spread of the water.
  • Hygrometers: humidity readings show whether moisture is trapped in a room or wall cavity.
  • Visual inspection: we check supply lines, drains, water heaters, appliances, roof penetrations, and windows for the most common failure points.

You get a clear answer on where the water is coming from and how far it has traveled, with photos and readings you can share with your insurance company.

What Happens After We Find the Leak

Finding the leak is step one. Stopping the damage is what protects your property:

  1. Stop the source. We help shut off the water and make the area safe.
  2. Document everything. Photos, moisture maps, and notes for your claim.
  3. Remove standing water. Fast water extraction if water has pooled.
  4. Dry the structure. Commercial air movers and dehumidifiers for structural drying, monitored daily until materials reach dry standards.
  5. Prevent mold. Antimicrobial treatment, and mold remediation if growth has already started.
  6. Restore. Repair drywall, ceilings and walls, and flooring so your home looks like nothing happened.

Frequently Asked Questions

Do you have to cut into my walls to find a leak?

Usually not. Thermal imaging and moisture meters let us locate most leaks from the surface. If an opening is needed, we keep it as small as possible and explain why first.

Can you fix the pipe itself?

Pipe repair is plumbing work. We pinpoint the leak, stop the water damage, and dry and restore your property. We can work alongside your plumber so the repair and the restoration happen in the right order.

How fast can you get here?

Our crews are available 24/7, and we respond quickly to most Los Angeles neighborhoods. Call (323) 677-2811 and we will give you an arrival time on the phone.

Is a slow leak covered by insurance?

It depends on your policy. Sudden leaks are commonly covered, while long-term leaks may not be. Our documentation helps your adjuster see exactly what happened.
