From sheathing treatment to exhaust fan rerouting and ventilation correction — the full scope of attic mold remediation in Beaverton, OR.
🔍
Attic Mold Assessment & Ventilation Survey
Our Beaverton, OR attic specialists enter your attic with moisture meters, a thermal camera, and a ventilation calculation worksheet. We measure sheathing moisture content, identify the extent of fungal growth, assess soffit vent count and placement, check ridge vent condition, and look for exhaust fans terminating inside the attic. Full findings documented before any remediation scope is proposed.
🔨
Roof Deck Sheathing Mold Treatment
Loose surface mold removed by HEPA vacuuming and wire brush. EPA fungicide applied followed by penetrating borate solution. Sections with advanced degradation are flagged for sheathing replacement.
💨
Bathroom & Kitchen Exhaust Fan Rerouting
Improperly-terminated exhaust fans are corrected by extending ductwork through the attic to a gable, soffit, or roof cap termination point — properly insulated flexible duct or rigid metal, sealed at the fan housing and at the exterior cap. This is typically a same-day correction completed alongside the mold treatment in your Beaverton home.
🏔
Soffit Vent Addition & Ridge Vent Assessment
Additional soffit vents where NFA is insufficient. Eave bays cleared of insulation obstruction and baffled to maintain airflow pathway. Ridge vent assessed for blockage or inadequate design.
😵
Attic Insulation Removal Where Contaminated
Blown-in or batt insulation that has absorbed mold spores or become wet must be removed and replaced — it can't be treated in place. Our Beaverton, OR team removes contaminated insulation under HEPA containment as part of the attic remediation scope when warranted by the assessment findings.
