What drives the price
- Attic only or walls too. Fixr's average fills wall cavities and the attic. An attic alone costs much less.
- Fiberglass or cellulose. Both are common and close in price.
- Walls. Bob Vila notes wet-spray cellulose is used in existing walls, drilled and patched from outside.
Extra costs to plan for
| Item | Price | Source |
|---|---|---|
