Wet Insulation — Dry It or Replace It?

Quick answer

  • Fiberglass batts — sometimes dried if clean water and caught fast, but often replaced because they mat down.
  • Cellulose (blown-in) — usually replaced; it clumps and holds water.
  • Closed-cell spray foam — resists water but can trap it against framing.
  • Dirty water or mold — insulation is replaced.

Why wet insulation is a problem

  • It loses insulating value when compressed or clumped
  • It keeps the wall cavity wet, slowing drying
  • It feeds mold growth on the drywall paper and framing
  • Ceiling insulation can get heavy enough to sag drywall

How it’s handled

  1. Find the extent with moisture meters and thermal imaging.
  2. Remove wet insulation — often with a flood cut in walls.
  3. Dry the framing.
  4. Install new insulation once the cavity is dry.

Attic leaks are common with roof and swamp cooler problems — see mold in attic. Vault documents the damage, records daily moisture readings, scopes in Xactimate, and bills State Farm, USAA, Allstate, Farmers, and Bear River Mutual directly.
