The questions we hear most about attic mold.

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.
Some Sammamish 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.
