Spray Foam & Cellulose Insulation Built for Lebanon, NH
We provide spray foam and cellulose insulation to homeowners and businesses throughout Lebanon, NH and the Upper Valley.
Insulation for Upper Valley Homes That Actually Works
Each property gets a proper look before we recommend spray foam, cellulose, or both, since they serve different purposes.
Spray Foam Insulation
Spray foam creates an airtight, moisture-resistant seal in basements, crawl spaces, and rim joists. It delivers a high R-value per inch, and installation is quick and tidy.
Cellulose Insulation
Cellulose is our pick for attics. It’s made from recycled materials, treated against fire, mold, and pests, and blown in to cover the full attic floor and fill gaps around framing and wiring.
The Farnum Insulators Process
We Take a Look
It starts with a free consultation, no obligation, so our estimator can see what your home needs.
We Build Your Insulation Plan
Your plan comes from what the visit turns up, matched to your home's construction, age, and current insulation.
We Get to Work
When we start working, we protect your home by covering flooring and furniture and clear away all debris the same day. We walk you through the finished work before we leave.
You Feel the Difference
Homes we insulate tend to feel steadier and hold heat better afterward. Most projects wrap up within a single day.

Frequently Asked Questions
How much does insulation cost for a home in Lebanon NH?
Cost depends on what the assessment reveals: the area being treated, current insulation levels, and which products are the right fit. We provide a free on-site estimate so you have a clear number before committing.
What is the difference between spray foam and cellulose insulation?
Spray foam is best for basements, crawl spaces, and rim joists, areas where air sealing and moisture resistance are the priority. Cellulose is ideal for attics, where thorough, consistent thermal coverage over a large area matters most. For many Lebanon, NH homes, we recommend one or both depending on what the on-site assessment reveals.
Does Farnum Insulators serve towns outside Lebanon, New Hampshire?
Yes. We serve Lebanon, NH and surrounding Upper Valley communities including Hanover, Enfield, Canaan, and towns across western New Hampshire and eastern Vermont. If your town isn’t on our map, reach out. We serve a wider area than what we list.
Does Farnum Insulators start with an energy assessment before recommending insulation?
Yes. Every project begins with a free on-site walkthrough of your Lebanon home. We inspect the attic, basement, crawl spaces, and rim joists, then explain what we found and what we recommend. Blower door testing, and infrared imaging when possible, are offered separately as a paid service.
