Get matched with top insulation pros in Waltham, MA

"We had this company come to do insulation for our whole home - attic and walls (through Mass Save). Not only did they do what was in the original contract, but they also added insulation to our garage ceiling AND to an open wall that was being worked on for an unrelated home reno project! They did 3 days of work in 1 day & stayed late to vacuum and clean up. They were very professional, extremely efficient, and I love that it's a family operated company. Ivan, their office resource who helped book the appointment, was also a pleasure to work with throughout the process. We highly recommend using this company for any insulation needs."

"Professional crew; work was done quickly, with minimal disruption and fairly good cleanup. The house is older and the crew chief took reviewed the interior carefully to insure there would be no damage to the walls in the insulation process."

"Our central air conditioning system failed during the worst heat and humidity streak in more than a decade. When our AC contractor arrived to look at replacing the system, he pointed out that none of our 3 attics were insulated. We called Coleman Spray Foam. The put a highly knowledgeable rep on-site in less than 24 hours. One day later we received and signed their proposal. Crews arrived 2 days later and worked in unbearable heat and humidity in our attics until we had R50 insulation (needed for AC/Heat Pump). I would have them back in a heartbeat and highly recommend them for anyone in need of spray foam insulation."

"Outstanding insulation work from start to finish. The crew was professional, punctual, and paid attention to every detail. The quality of the installation was excellent, and the difference was noticeable immediately. Everything was left clean and organized after the job was done. Highly recommend to anyone looking for top-quality insulation work."

"Anthony and his team did an incredible job insulating our full gut remodel in Fairfield. He took the time to put together a foam package that made the most of our budget. The crew was polite, neat and efficient. They took great care to cover finished surfaces before spraying and did a thorough clean up so we could jump right into sheet-rocking. Highly recommended for quality of work, constant communication and value!"
