Groundwater & Basement Water Intrusion in Bothell, WA
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
Why does the roof fail at the valley rather than anywhere else?
Because that is where the water is. A valley takes everything from the two planes that drain into it, so a channel a few inches wide can be carrying the runoff from a large part of the roof. It is under far more load than the surface either side of it.
Does the long wet season change that?
It makes it continuous. With rain from autumn through spring and no dry stretch in between, a valley here is working for six months at a time rather than during a storm and then drying out. Anything marginal about it is being tested every day of that.
Where does the water show up inside?
Below and to the side, following the framing. Water getting past a valley runs on the structure before it reaches a ceiling, so the mark inside is often in a different room from the valley above. The search follows the rafters up rather than working from the stain.
