Warm spot on the floor? Cracks in the tile? The sound of water running under your house? You may have a slab leak: a broken water line under your concrete foundation. Water from a slab leak spreads under flooring, wicks up into walls, and can feed mold long before you see a puddle. ASAP Water Damage Restoration Los Angeles finds the wet areas, dries your home properly, and restores what the water ruined.

Call (323) 677-2811 24/7 if you suspect a slab leak.

Slab Leak Warning Signs

  • Warm or hot spots on the floor (a hot water line leak)
  • Damp carpet, or wood floors that cup or buckle
  • Cracked tile or new cracks in the slab
  • Water pooling along baseboards with no visible source
  • Musty smells or mold near the floor line
  • A water bill that keeps rising
  • Low water pressure or a water heater that runs constantly

Why Slab Leaks Need Fast Restoration

Water under a slab has nowhere to go but out and up. It soaks padding and subfloors, climbs into drywall and baseboards, and keeps humidity high inside the home. Fixing the pipe stops new water, but it does not dry what is already wet. Without professional drying, trapped moisture can lead to mold, odors, and flooring failure months later.

Our Slab Leak Water Damage Process

  1. Moisture mapping. Thermal imaging and moisture meters show how far the water has spread across floors and walls.
  2. Work with your plumber. The slab pipe repair is plumbing work. We coordinate timing with your plumber so drying starts right after the leak is fixed.
  3. Remove what can’t be saved. Wet padding, soaked baseboards, and damaged flooring are removed carefully and documented.
  4. Extract and dry. Water extraction, then structural drying with air movers and dehumidifiers, checked daily until readings reach dry standards.
  5. Protect against mold. Antimicrobial treatment, plus mold remediation if growth is present.
  6. Restore your floors and walls. We put your home back together so it looks and feels normal again.

Does Insurance Cover Slab Leaks?

Many policies treat the pipe repair and the resulting water damage differently. The damage to your floors and walls is often covered when the leak is sudden, even if the pipe itself is not. We document every step with photos and moisture readings, and our insurance claim assistance team can talk to your adjuster for you. Always confirm the details with your own policy.

Not Sure It’s a Slab Leak?

Water on the floor can also come from a supply line, water heater, or appliance. Our leak detection service finds the true source first, so you only pay to fix the real problem. If a pipe has burst above ground, see burst pipe cleanup.

Frequently Asked Questions

Can I wait to deal with a slab leak?

Waiting usually makes the damage and the bill bigger. Water keeps spreading under flooring and into walls every day the leak runs.

Do you repair the pipe under the slab?

No. That repair is done by a licensed plumber. We handle everything the water damaged: drying, mold prevention, and restoring floors and walls.

Will you have to remove all my flooring?

Not always. We take moisture readings first and remove only what is wet beyond saving. Some flooring can be dried in place.

How long does drying take?

It depends on how much water spread and what materials got wet. We check readings every day and tell you when your home is fully dry.
