"I hired Smart Roofing Systems to install some insulation for me. They were extremely prompt in calling me back, and working with me to get the project started. When the time came for the insulation they were very professional, and did excellent work. One of the things that really surprised me was when they were done they had vacuumed the mess on the floor, and made it look like they hadn't even been there. I would definitely hire them again, and recommend them. Thank you Smart Roofing Systems!"

"These guys will get the job done right, and they will get it done in a timely manner. From start to finish they were on top of it, spending the extra time to make sure things were done perfectly. Kirk and Max are just a hard working father/son duo who actually want to help the customer accomplish their dreams without taking advantage of their wallet. These guys are a breath of fresh air in the construction industry and will bend over backwards to help you get your job done, for a GREAT PRICE, in a TIMELY MANNER. You really wont be disappointed if you use MAXIMUM INSULATION for ANY of your insulation needs."

"We had both the spray foam and injection foam. The team that did the attic were very polite, professional, and efficient. The gentleman who repaired the hole in the hall ceiling did a wonderful job we have plastered walls. You cannot even tell where they made the opening. Ken crew #1 did the outside walls, and you would not even know that they had been here. I would encourage anyone who is looking to insulate their homes to look into this firm. RetroFoam contractors were the best contractors we’ve ever had doing work in our home. Amy at the call center was very pleasant, helped answer. Any questions we ran into before they came. Very thankful we chose RetroFoam of Michigan to do our insulation."

Injection Foam Insulation
"Everyone was so professional from the crew that came to measure up the attic space, to the installers and especially Erika, she went above and beyond her duty. Thank you, Jerry David Clarkston Community Church"
