About Insulation Services in Denver
Insulation services cover attic, wall, floor, and crawl space insulation using materials like fiberglass batts, blown-in cellulose, spray foam, and rigid board. Proper insulation reduces heating and cooling costs and improves comfort year-round.
Typical costs: Attic insulation runs $1,500–$4,000 for a typical home. Spray foam for a crawl space or basement is $2,000–$6,000. Whole-home insulation upgrades can be $5,000–$15,000.
Common projects include:
- Attic insulation upgrade

Simple insulation upgrades in existing walls and attics usually don't require permits. If the work involves modifying structure or electrical, permits may apply.
