Cellulose Insulation in Alstead NH

Cellulose is our recommendation for attics. Made from recycled materials, it blows in to cover the full attic floor, filling around framing and reaching every corner. It delivers strong, consistent thermal coverage and works well in most homes.

Frequently Asked Questions

Why is spray foam recommended for basements in Alstead NH?

Spray foam creates a complete air and moisture barrier in basements and crawl spaces. It delivers strong R-value per inch and holds up over time. At Farnum, we install it cleanly and clean up fully after every job.
Efficiency Vermont and Energy Star recommend R-49 to R-60 for attics and R-15 or higher for basement walls. Many older homes in the area are well below these levels. Our team measures your actual levels during the initial walkthrough and provides a clear picture of where your home stands before making any recommendations.
We handle the Efficiency Vermont incentive process with you from start to finish. As a recognized Efficiency Vermont partner and Energy Efficiency Excellence Network contractor, we know which programs are currently available and what documentation is required. We walk you through every step so you access the maximum benefit available for your project.
Spray foam in basements and crawl spaces creates a moisture barrier that reduces water infiltration risk. While insulation is not flood protection, properly sealed basements manage moisture far better than unsealed ones. We select the right material for your specific exposure.
