The questions we hear most about attic mold.

Most attic mold in Bellevue 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 Bellevue attics only have an interior hatch, in which case we'll take care to protect flooring and furnishings along the path.
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.
