Balancing intake and exhaust is often the single biggest factor in whether Derwood attic mold returns.
A shockingly common Derwood culprit: bathroom exhaust fans venting directly into the attic instead of outside through the roof or wall.
Insulation touching an actively moldy roof deck gets bagged and removed rather than treated in place.
We clean the whole affected zone, not just the most visibly stained rafters.
After treatment, we verify soffit-to-ridge airflow is actually working the way it's supposed to.

The questions we hear most about attic mold.
Most attic mold in Derwood properties traces back to poor ventilation or an interior exhaust fan venting into the attic, not a roof leak.
We'll show you exactly which sections need replacement before doing any of it.
Some Derwood attics only have an interior hatch, in which case we'll take care to protect flooring and furnishings along the path.
A standard treatment typically takes half a day to a full day depending on square footage and severity.
Sealing those gaps is sometimes part of the fix alongside the mold treatment itself.
