A Portland attic treated without fixing the airflow behind it is a job that's likely to repeat within a year or two.
Four reasons Portland property owners trust us with this specific job.

Every Portland attic job includes a ventilation assessment, not just a mold treatment. Our Portland roof-access gear meets standard safety protocol for working above living space.

When roof access allows it, much of an attic job can be done without disturbing your living space below. Our Portland roof-access gear meets standard safety protocol for working above living space.
Every Portland job gets scoped to the specific problem, not a generic checklist.

Dark staining on the underside of roof sheathing gets HEPA-vacuumed and treated with an antimicrobial rated for structural wood.
Balancing intake and exhaust is often the single biggest factor in whether Portland attic mold returns.
A shockingly common Portland culprit: bathroom exhaust fans venting directly into the attic instead of outside through the roof or wall.
New insulation goes in only after the surface beneath it has been fully treated and verified.
Every treated surface gets HEPA-vacuumed to remove loose spore material before any sealant or coating is applied.
After treatment, we verify soffit-to-ridge airflow is actually working the way it's supposed to.
