How the New Orleans restoration team handles slab leak water damage
Rapid local response
Dispatch runs 24/7 across New Orleans, and any active water is treated as urgent at any hour, storms and holidays included.
IICRC S500 drying standard
The drying team sizes air movers and LGR dehumidifiers to the class of loss and keeps them running until the readings say dry.
Claim-ready documentation
A moisture map, daily psychrometric logs and timestamped photos taken before demolition go into the file for the adjuster.
Humid Gulf Coast know-how
Outdoor air near the river holds a lot of moisture, so the crew dries inside closed containment instead of opening windows.

How slab leak water damage is handled in New Orleans
Map the leak
Moisture readings and the plumber's tests find where water starts.
Lift and open
Wet flooring and baseboards come up.
Dry the concrete
Dehumidifiers run, with desiccant units for dense slabs.
Verify
Final readings confirm the floor and walls match dry targets.
New Orleans is built on thousands of feet of soft sand, silt and clay that subside through consolidation, oxidation of organic soils and groundwater pumping. That movement can stress buried plumbing over time. A leak under a concrete floor, usually called a slab leak, keeps wetting flooring and the bottoms of walls until it is found, and it often shows itself late.
Signs of a leak under the floor
- A warm spot on the floor where a hot water pipe runs below
- A water meter that keeps moving with every fixture shut off
- The sound of running water when nothing is turned on
- Damp carpet, lifting laminate or cupping hardwood near the leak
- A water bill that jumps with no change in use
Tracing before tearing out
A plumber uses pressure tests and listening gear to find the failed pipe, and the restoration crew maps moisture across the floor. Doing both before demolition limits how much flooring comes up. Where the pipe sits under concrete, the break may need to be reached from above, so the extent of opened floor depends on what the plumber finds. Photographs and moisture maps record the starting condition.
Drying concrete takes patience
Concrete holds water like a sponge and releases it slowly, and humid Gulf air does not help. Wet flooring is lifted, baseboards come off, and LGR dehumidifiers and air movers run, with desiccant drying added for stubborn slabs. Readings of the slab and the walls beside it are logged daily until the numbers settle. See structural drying for the equipment used.
Sewage from a drain leak
Not every leak under a floor is clean. A broken drain can release sewage into the soil and up through the floor, which turns the job into sewage backup cleanup with containment and sanitizing. Insurance wording on slab leaks varies, so the policy and the insurer decide what is paid.

Slab Leak Water Damage questions in New Orleans, LA
Water spreading as you read?
Call and describe the warm spots or meter readings. The crew explains the plumber's role, which flooring may lift and how drying is logged.
(888) 417-5665 Slab leak questions answeredHow do I know if I have a leak under the floor?
Warm spots, a meter that keeps moving, the sound of running water and damp flooring are the usual signs. A plumber's pressure test confirms it.
Does the soft ground cause slab leaks?
It can contribute. The ground here subsides over time, which can stress buried plumbing, but a plumber must confirm the actual cause of any leak.
Will my floors have to come up?
Wet flooring usually does, because water gets under it and stays. Moisture readings show how far the damp spread, and only affected areas are lifted.
How long does concrete take to dry?
It varies with thickness, humidity and equipment. Daily readings decide when it is dry, and humid New Orleans air can make it slower than expected.
Is a leak under the floor an emergency?
Yes. It wets materials constantly, raises the bill and can lead to damp materials growing mold within 24 to 48 hours, so it should be traced and dried promptly.
Who fixes the pipe?
A plumber repairs or reroutes the pipe. The restoration crew dries the structure and documents the damage, and both jobs are scheduled so repairs do not interrupt drying.
