Get matched with top insulation pros in Greenwich, CT

"the insulation they recommended saved me about 5000kw a year. the amount of money i am saving is far more the insulation payment on my Eversource bill. No money cost to me out of pocket and my electric bill dropped quite a bit. best move i ever did."

"My experience with everyone was excellent. It started with an energy assessment followed up with spray foam insulation throughout my home. Good customer service and follow-up. All was explained thoroughly throughout the process and they welcomed my questions. I highly recommend this service."

"Discount Insulation quoted a fair price, showed up on time, and did an excellent job insulating the crawl space in our new home. I already feel a difference in how warm our home feels. Stu, the owner, is wonderful to work with and is an excellent resource for all things insulation and beyond. Highly recommend hiring them for any insulation projects in your home."

"The crew worked quickly and efficiently to replace and upgrade the fiberglass batts in our basement and crawl space. I’m pleased with the outcome. (I put in even more wire supports afterwards — to secure the insulation between the joists — but that’s just my OCD.) It was a relatively small job for this company and I thought the cost was fair."

"Great job at a reasonable price. We can already feel the difference. I would recommend Foamco, and would use them again."

"I don’t know why anyone would hire anyone else. Anthony is courteous/responsive, knows insulation cold, was quick to provide estimates and service and is smart about his hires, with net results—great workmanship at a very fair price."

"Ecofoam insulated my attic with closed-cell spray foam and the results came out great. The space feels completely sealed and much more comfortable already. Sevi and the team were very professional, easy to work with, and kept me updated throughout the whole process. I would highly recommend EcoFoam for anyone looking for quality insulation work."

"We could not be more pleased with the work performed by Koala Insulation of the Sound Shore. From start to finish, the team was incredibly professional, detail-oriented, and went above and beyond our expectations. The work was done carefully and thoroughly, and everything was explained clearly along the way. Paul and Brian, in particular, were exceptionally patient and knowledgeable, taking the time to answer all of our questions and making sure we felt comfortable with every decision. The results were immediate—our home is noticeably more comfortable, and we’re already looking forward to significantly lower energy bills. If you’re considering insulation work, I highly recommend this company. Excellent craftsmanship, outstanding customer service, and a job very well done."

"Arrived on time. Spent 2 1/2 hours doing preparation to protect our home prior to start to spray foam. Quality of the insulation installation is top notch. Very professional and respectful. I could not be happier with the final project!"

"Window & roof insulation quick, easy, & affordable!"
