A shockingly common Mercer Island 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.

After treatment, we verify soffit-to-ridge airflow is actually working the way it's supposed to.

Answers to what Mercer Island customers ask before booking attic mold removal.
Condensation from trapped warm, humid air is often the real culprit, especially in colder months.
Only insulation that's been contaminated and can't be cleaned gets removed and replaced — we're not looking to upsell a full attic redo.
When roof access is workable, much of the job can happen without disturbing your living space.
Jobs requiring insulation replacement can run a day or two longer.
Sealing those gaps is sometimes part of the fix alongside the mold treatment itself.
