Frequently asked questions
How much does it cost to insulate an attic?
Most 1,200 sq ft attics run $1,700 to $3,200 installed with blown fiberglass or cellulose at R-49. DIY with rented equipment usually lands between $900 and $1,500.
Does new insulation pay for itself?
Typically yes — an under-insulated attic upgrade cuts 10 to 20% off heating and cooling bills, so most jobs pay back in 3 to 7 years. Federal and utility rebates shorten that further.
