Groundwater & Basement Water Intrusion in Santa Monica, 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

It barely rains and it is never hot. Which one sets the drying time?

The temperature, not the rain. Cool air carries much less moisture away from an open assembly than warm air does, and with July highs around 69 degrees the air here never gets the capacity that an inland summer provides. A wet assembly takes noticeably longer than the low rainfall would suggest, and that is planned for rather than discovered.

A unit upstairs flooded. How far down does it go?

As far as the framing carries it, which in a low-rise building is usually more than one floor. Water runs along joists and down inside walls and shows up in homes that were not the source. Readings are taken in each affected unit, ceilings are opened where the framing is wet, and the whole stack is dried as one assembly.

Why is the seaward wall still reading wet?

Because it sees the most moisture and the least drying. Stucco holds water in its base coat, and a wall facing steady cool damp air from the ocean gives it up slowly. That elevation is read separately, and anything fastened against it stays off until the base readings hold, rather than being closed when the interior side looks finished.
