Happy Customers & Installs

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.

We hired 5C Energy to install insulation and door-sweeps and were very impressed with their work! Manny and crew were friendly, knowledgeable, courteous, and professional. They came right on time and listened to concerns we had about our energy efficiency in the house before getting to work. We recommend 5CEnergy and couldn't be happier with Manny and crew's work!!

I never take the time to write reviews but felt I had to as 5C was one of the few bright spots in our construction project. They were an extremely professional crew , communicated well, hard working, cleaned everything up and all of this at the best price of the three bids I received. When the building inspector came he said they did an excellent job and did not have any corrective action, unlike for our electrician...

I would recommend this company to anyone needing insulation to their home or even business. They were willing to insulate under my double wide trailor that no other co. Would take on. This co. Was professional, quick but tidy. Employees were polite and more then willing to answer all my questions. Thank you for making my home warm and saving me money in my heating bill.

5C Energy installed a vapor barrier, basement insulation and attic insulation. I cannot say enough about the job they did. The communication with the crew was fantastic and the job was neat and the attention to detail was 2nd to none. I will be using them in the future for another small project. Thank you

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!!
