Groundwater & Basement Water Intrusion in Tigard, OR
Basement seepage, failed sumps, and hydrostatic pressure against the foundation are extracted and dried, and the path from the ground is identified so the loss does not repeat. Groundwater and basement seepage are extracted and dried only after the path from the soil is identified — a wall, a slab, a drain, or a failed sump. Drying the interior without stopping that path returns the same water to the same floor.
Frequently asked questions
The storm was unremarkable and the creek flooded anyway.
How wet the preceding weeks have been decides it, more than the storm itself. By midwinter the basin has no capacity left, so a perfectly ordinary system produces a rise that the same rainfall in October would not have. Looking at the month behind you predicts this far better than looking at the forecast ahead, which is why the creek catches people out with unremarkable storms.
Nothing has ever pooled under the house and the smell is getting worse.
That is vapor rather than flooding and it is the characteristic local problem. Through the wet season the ground beneath stays close to saturated and moisture moves continuously into the framing above, with nothing to pump at any point. A well-sealed ground barrier addresses it far better than ventilation, since outdoor air here dries nothing between November and March.
When is a crawl space inspection worth arranging?
Midwinter, when the ground is holding as much as it will hold all year. Looking in August shows you a crawl space in its best condition, which tells you very little about the months that cause the damage. February shows where water arrives, how far it spreads, and whether the ground barrier is intact. Scheduling it then costs nothing more than scheduling it in summer.
