Insulation for Chesterfield NH Homes That Actually Works

We offer two core insulation services: spray foam for basements and crawl spaces, where it seals out moisture and drafts, and cellulose for attics, where it's blown in for complete coverage. We match each project to what your home actually needs.

Spray Foam Insulation

Basements and crawl spaces near the Connecticut River get an airtight, moisture-resistant seal from spray foam, along with a high R-value per inch and a clean install.

Cellulose Insulation

Throughout Chesterfield, cellulose is our recommendation for attics. Made from recycled materials, it's blown in to fill cavities and cover the attic floor wall to wall.

Frequently Asked Questions

Should my Chesterfield NH house get cellulose, spray foam, or both?
It comes down to the space. Cellulose is better for attics, while spray foam handles basements and crawl spaces where moisture control matters more. Many homes need both.
What R-value target should Chesterfield NH homeowners aim for?
Aim for R-49 to R-60 in attics and R-15 or higher on basement walls, per Energy Star guidelines. We'll take a look at your home's current insulation during your free quote visit.
Does my Chesterfield NH household need to relocate during spray foam installation?
It comes down to the areas being treated and the product involved. We keep the workspace ventilated throughout installation and go over exactly what to expect during your free quote visit.
How much can new insulation cut down my energy costs?
That varies based on your home's current insulation levels and air leaks. Sealing the right areas tends to make your home noticeably more comfortable. We'll figure out exactly where you're losing heat during your free quote visit.
