How much does attic insulation cost in Suffolk County?
“Blown-in attic insulation runs roughly $1.00 to $2.80 per square foot installed, which puts a typical 1,200 square foot Long Island attic somewhere around $1,700 to $3,400 before rebates. The spread comes from material, target depth, how much air sealing the attic needs first, and whether existing insulation has to be removed.”

“Suffolk County sits in climate zone 4, and the Department of Energy recommends R-38 to R-60 for attics here. In blown fiberglass that is roughly 13 to 20 inches of settled depth, and in cellulose roughly 10 to 16 inches.”
View in the company profileBlown-in or batts for an attic?
“Blown-in for almost every attic we see. Batts have to be cut and fitted around every joist, wire, pipe, and brace, and any gap left behind is a hole in your insulation.”
View in the company profileWill new insulation stop my ice dams?
“Usually, when it is done with air sealing. Ice dams form because heat escaping into the attic melts snow on the warm part of the roof, and that water refreezes when it hits the cold overhang.”
