Groundwater & Basement Water Intrusion in Corvallis, OR
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
What was added to the outside of the wall?
Rigid foam board, fixed over the original sheathing with new siding nailed on through it. It was done widely in this period to improve insulation, and in most cases here the siding went on tight against the foam with nothing at all between the two.
Why does the missing gap matter so much here?
Because of the length of the wet season. Any cladding lets some water past, and a gap behind it lets that run down and out. Without one, it sits on the foam against the sheathing, and in a climate with rain from October to May it never gets a chance to leave.
What is found when the siding comes off?
Usually sheathing that has been damp for a long time, with the framing behind it sound in some places and gone in others. The pattern follows the fixings and the joints, so the useful first step is opening a small area at a lower corner rather than guessing.
