Groundwater & Basement Water Intrusion in Los Angeles, CA
Basement seepage, failed sumps and water through the slab are extracted and dried, and the path from the ground is found so the floor stays dry next season. The path from the ground is named first: through the wall, up through the slab, back through a drain, or from a sump that stopped. The space is extracted and dried, with the porous materials the water touched removed, and the delivery is addressed, because a dried floor only stays dry if the water stops arriving.
No obligation: the assessment comes before any scope
Often needed alongside
- Structural Drying & Dehumidification
Sealed air movers and dehumidifiers bring framing, subfloor and drywall back to a measured dry standard, with daily readings logged from inside the material.
- Emergency Water Extraction
Standing water is pumped and extracted around the clock, before it climbs the walls and soaks the subfloor. Same-day response where coverage allows.
- Mold Inspection & Testing
An independent assessor confirms whether the assembly that got wet is actually dry, whether growth started while it was not, and how far it reaches.
Frequently asked questions
How long does a slab leak under hardwood take to dry?
Longer than the rest of the job. Hardwood glued or nailed over a slab hides the leak, and by the time it cups the concrete has been wet for weeks. The contractor lifts the floor over the wet area, dries the slab with mats and a sealed run, and reads it daily; in Los Angeles's dry air the walls are done in days, but the slab can take two weeks.
The crawl space under a hillside house is wet after February rain. What is the job?
Drying from below, and finding where the water came in. The contractor removes the soaked insulation between the joists, seals the crawl, runs air and dehumidification underneath, and reads the subfloor from below. Because hillside runoff will return next winter, the scope names what has to change about the drainage as well.
Can the plaster in a 1950s house be dried in place?
Usually, yes. Plaster over lath is dense, so the surface reads dry while the lath still holds water, but in this dry air it dries faster than it would in a humid city. The contractor drills at the base to move air behind the plaster, keeps the room sealed, and reads the lath until it holds the standard before anything is patched.
