"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."

"I had some insulation issues in my home over the early winter months. I reached out to a few companies; some who never got back to me. Brian at Koala reached out, made an appointment soon after contact, and provided a very knowledgeable evaluation of my issues. His team came out and did great work and even cleaned up after. Great communication. And even went the extra mile to stay on me about getting the necessary documents to make sure I took advantage of rebates that I qualified for. A++ from me."

"I had my attic insulated by EcoFoam and I?m honestly really happy with how it came out. The crew was on time, clean, and explained everything before they started. The attic looks great now and the house already feels warmer with no drafts. Sevi was easy to work with and kept me updated the whole time. Overall the job was done right and I?d definitely recommend them to anyone who needs insulation."
