Efficient, Professional Mold Testing & Sampling in Portland, OR

We send a mold inspector to your Portland property, sample suspected growth and post-remediation areas, and deliver written findings within 1 to 2 business days.

AccuGuard of Portland performs mold inspection and sampling at houses, rentals, and commercial buildings throughout Portland, OR. A technician reviews the areas you are worried about, documents the moisture conditions that can support microbial growth, collects air and surface samples where they are warranted, and submits them for professional laboratory analysis. Written results are generally available within 1 to 2 business days, with clear findings and recommended next steps.

Rain shapes most of what we find here. Nearly 90 percent of Portland’s annual rainfall arrives between mid-October and mid-May, and only about 3 percent falls in July and August, so a quiet wet-season leak can run for months. Totals also differ across the metro, with the West Hills at 60 inches a year and the airport area around 35 to 37, which is why we treat a Beaverton crawlspace, a Tigard roofline, and a Milwaukie basement as separate questions.

Restoration and remediation contractors, property managers, real estate professionals, insurance adjusters, and homeowners use our reports to decide what happens next, including post-remediation clearance testing after the work is finished. AccuGuard was founded by restoration professional Ben Doebler, and our Mobile Lab drives to job sites across the territory.
