Winter condensation and ice dam damage cause a different kind of attic mold than a simple ventilation gap — and they need a different diagnosis.

WQB Mold Removal's Seattle attic service pairs mold treatment with the ice dam and condensation diagnosis most cold-climate attic problems actually need.
We built this as its own specialty because attic work brings different hazards and different seasonal causes than living-space mold.
Four reasons Seattle property owners trust us with this specific job.
This diagnosis changes the fix compared to a simple summer ventilation gap. Getting the cause right the first time saves a repeat Seattle, WA visit next winter. We check insulation R-value and coverage gaps while already assessing the mold.
Our technicians move safely across roof framing without damaging insulation or ceiling drywall below. We schedule carefully around weather when working a Seattle roof in colder months. Our Seattle roof-access gear meets standard safety protocol for winter work.
Every Seattle attic job includes checking soffit intake, ridge exhaust, and insulation coverage gaps. We'll show you exactly where the gap is before proposing a fix. We check insulation R-value and coverage gaps while already assessing the mold.
We won't leave a Seattle attic under-insulated after a treatment. New insulation only goes in once the surface beneath has been fully treated. Our Seattle roof-access gear meets standard safety protocol for winter work.
Here's exactly what our Attic Mold Removal service covers in Seattle, WA.

Dark staining from winter condensation on roof sheathing gets HEPA-vacuumed and treated with a structural-wood-rated antimicrobial.
Fixing this prevents both the ice dam and the mold pattern that follows it in your Seattle attic.
Blocked or insufficient soffit vents disrupt the airflow that's supposed to keep a Seattle, WA attic cold and dry in winter.
Gaps around recessed lighting, attic hatches, and plumbing stacks let warm interior air leak into the attic, driving condensation.
Insulation touching an actively moldy roof deck gets removed rather than treated in place.
This final check is what separates a real fix from a Seattle attic that looks fine until next winter.
