Types of Insulation
We offer multiple insulation options to meet your specific needs and budget. Insulation is a key part of crawlspace encapsulation and basement finishing projects.

- Permanent solution - never sags or settles
Blown-In Cellulose
An eco-friendly option made from recycled materials. Perfect for attics, walls, and hard-to-reach areas.

“We had such a great experience with Nason's! The estimator came out the day after we called. We had a quote within a couple days and the project was scheduled within the week. The crew that put in the insulation was great! They were professional, great communicators and very professional.”

“I've used Nick for all of my insulation and waterproofing needs and he's never failed me. Always on time, always polite, always a good price. I have nothing but amazing things to say about him and his team. We recently got our house re-insulated and it cut more than half of our heating bill.”

“I needed to insulate my cellar and I had Nick and his crew come and. I'll definitely recommend him to others when a job that needs to be done correctly and in a professional way give him a call and ask for his help and he'll get back to you in a timely way just as soon as he can.”
Home insulation questions from Bangor-area homeowners
What type of insulation is best for my home?
Spray foam gives the highest R-value and an air seal, ideal for attics, basements and crawl spaces. Blown-in cellulose is cost-effective for attics and existing wall cavities. We recommend the right mix during your free consultation.
How much can I save on heating bills?
Most homeowners see energy savings of 20–50% after proper insulation and air sealing. Savings depend on current insulation levels, home size and heating system.
How do Efficiency Maine rebates work?
Efficiency Maine offers rebates of $4,000–$8,000 for qualifying insulation projects, with enhanced rebates for income-qualified homeowners. As a registered vendor we handle the paperwork for you.
How long does insulation installation take?
Most residential projects take one to three days. An attic can often be done in a single day; whole-home projects take longer. You get a timeline with your estimate.
Does spray foam off-gas?
Modern spray foam is safe once cured. The home is ventilated during a brief curing period, typically 24 hours, after which the foam is inert.
Do you insulate basements and crawl spaces?
Yes. Basement walls, rim joists and crawl spaces are where many Maine homes lose the most heat. We pair insulation with waterproofing or encapsulation when moisture is present.
