The Leading Spray Insulation Company in Massachusetts and Rhode Island

Spray foam insulation is a highly effective material used to create an airtight barrier in walls, ceilings, and floors. Spray foam never loses its shape, making it an ideal long-term solution. There are two variations of spray foam insulation: open cell and closed cell.

Open cell foam is soft and pliable and a great option for reducing sound noise and filling awkward crevices. It won’t crack, bend, or warp.

Closed cell foam is rigid and moisture resistant, making it an ideal choice for blocking airflow, reducing noise, and in areas that might experience water intrusion. 

Our team will help determine which foam insulation is best for a property.

5C Energy Inc. is the best insulation company because of our team’s expertise and experience in the field. We provide accurate cost estimates, and our commitment to quality and customer satisfaction ensures you receive the highest level of service and the best possible results.

Insulation Solutions Reviews

5C was a great company to have working on my home. They were professional, friendly, informative and their work was impeccable. They didn't cut corners and they had to deal with some challenges due to conditions in my crawlspace. Highly recommended.

The 5C crew spent 8 hours insulating my house, (no lunch). Toby, Ryan, Eric & Rob worked on the house. All are exceptional workers, very professional, patient & kind. They all took the time to explain any question I had and to explain what & why they were doing what they were doing!! Whoever does the hiring at this company should be applauded as these are the best "workers" I have seen in a long time. I couldn't be happier with the time, effort and thoroughness of their work. (They even 'discovered' 2 of my bathroom vents that the original builders had not vented correctly and remedied that situation). My house is toasty warm!!

This was an amazing experience, having our house insulated and further weatherized this week. 5 C Energy should be very proud of its managers, Vince and Eric, and the rest of the team--they were efficient, professional, safety conscious, and so pleasant. We would rate this experience as 10 out of 10!! Vince checked with us often as the work proceeded, which we appreciated. Great communication and people skills. Glad we participated in the Mass Save program. Highly recommend this company and thanks to Rise Engineering (Matt) for coordinating.

As a participant of the Mass Save program, 5C Energy Inc was sent to our house to do insulation work. The crew, Pat, Jason and Eddie were very professional, punctual and respectful of our home. The guys took their time and answered any questions we had. Highly recommend this company and would work with them again. Very happy with work done.
