Local Insulation Company in Londonderry VT
At Farnum Insulators, we insulate homes across Londonderry and surrounding areas with spray foam and cellulose. We've been doing this for over 20 years, and it shows in how comfortable your home feels.
Spray Foam & Cellulose Insulation for Londonderry, Vermont Properties
We offer both spray foam and cellulose insulation. The area we're insulating determines which one we use, so spray foam goes below grade and cellulose goes into the attic.
Spray Foam Insulation
Spray foam is our go-to for damp areas like basements and crawl spaces. It resists moisture and brings a higher R-value to the lower level of the house.
Cellulose Insulation
We blow cellulose into attics to cover the floor and seal gaps around framing and wiring. It’s made from recycled material.
