Our Lake Oswego crews treat the mold and the moisture source together — vapor barriers, drainage, and ventilation — not just the visible growth.
This service handles some of the most commonly misdiagnosed Lake Oswego, OR mold problems, since crawl space issues often show up as a mystery smell somewhere else in the house.
Four reasons Lake Oswego property owners trust us with this specific job.
Standard remediation gear doesn't always fit a crawl space — ours is built for it. We photograph crawl space conditions before and after so you have a visual record.
A properly sealed vapor barrier blocks ground moisture from evaporating up into the crawl space air. Our Lake Oswego equipment is rated for the humidity and tight clearance these spaces demand.
Standing water or poor drainage in a crawl space gets addressed alongside the mold, not ignored. We photograph crawl space conditions before and after so you have a visual record.
Some Lake Oswego clients set up a monitoring plan to catch humidity creep before it becomes mold again. Our Lake Oswego equipment is rated for the humidity and tight clearance these spaces demand.
Every Lake Oswego job gets scoped to the specific problem, not a generic checklist.
Heavy-duty polyethylene sheeting gets sealed across the entire crawl space floor and up the foundation walls.
Standing water in a crawl space needs an exit route, whether that's a new sump pump or corrected grading outside.
For chronic humidity problems, full encapsulation seals the entire space — floor, walls, and vents — into a controlled environment.
Exposed floor joists and subfloor wood get HEPA-vacuumed and treated with an antimicrobial suited for structural lumber.
We'll assess whether your crawl space should stay vented or convert to a sealed, conditioned design.
A humidity sensor left in the space can alert you before a small issue becomes a repeat mold problem.
