How much does it cost to replace attic insulation professionally?

Attic insulation replacement cost varies by attic size, access, existing material, and needed ductwork fixes. We confirm a firm price after an in-home inspection. In Depew homes, if ducts run through the attic, start by sealing leaks with mastic or metal tape and insulating accessible runs. Never use duct tape. A well-designed and properly sealed duct system can make your home more comfortable, energy-efficient, and safer. Leaky ducts can reduce heating and cooling system efficiency by as much as 20 percent.
