About our insulation services
Most of the heat a Spokane home loses goes straight out the attic, and most attics around here were insulated to a code that expired decades ago. Firefly adds and replaces insulation in attics, walls, and crawlspaces — blown-in fiberglass and cellulose, batt where it belongs, and the air sealing that makes any of it work. We measure what is there before quoting, because topping up a shallow attic and gutting a wet one are different jobs at very different prices. Ice dams, cold floors over a crawlspace, and rooms that never quite keep up with the furnace are the problems this fixes.

FAQs
Frequently asked
How do I know if my insulation needs replacing?
Cold rooms the furnace cannot keep up with, ice dams along the eaves in winter, and floors that stay cold over a crawlspace are the usual signs. If you can see the tops of the ceiling joists in your attic, there is not enough up there.
Will new insulation actually lower my heating bill?
In an under-insulated Spokane attic it is one of the few upgrades that reliably pays for itself, because it works every hour of every winter rather than only when something is running. We tell you honestly if your attic is already adequate.
