Groundwater & Basement Water Intrusion in West Covina, 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.

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 does a patio cover damage the main roof?
Through where it is fixed. The cover hangs off the fascia board at the roof edge, screwed into it along its whole length, and it is pitched so gently that a heavy storm backs water up at that top edge. It sits against the fascia and soaks into the rafter ends.
Why does it only happen in a big storm?
Because the fall is just enough for ordinary rain. Light rain runs off and nothing happens, and a February downpour arrives faster than the cover can shed it, so water stands along the top edge for as long as the storm lasts and finds the screw holes.
Does the cover have to come off to repair the fascia?
Usually a length of it does, which surprises people. The rafter tails and fascia behind it cannot be replaced with the cover hanging on them, so a piece of work that looks like trim repair involves taking down and refitting part of the structure.
