"These guys are the pros for insulating and improving your home energy efficiency. They learned what I was trying to do, reduce second floor temp difference to reduce cold air down draft to the first floor. I had an energy audit done by a separate contractor and found the top 5 things I could do to improve the draft issue as well as improve my energy efficiency. Ecology Products came and recommended how to insulated my attic and crawl spaces to create a better insulating layer. But what I did not expect but blew me away was three things: 1. They recommended a batting backed vinyl solution vs foam board in the crawl spaces to double the R rating. 2. They removed useless batting on the roof side of the crawl space. Not only was the batting useless, it actually blocked airflow causing moisture and a small patch of black mold was found in the attic as a result. They also sprayed mold killer to resolve that issue which they said is very common. They did this at no extra cost. 3. They we extremely responsive to the inquiry, initial meeting and actual insulation work. It was all done in less than 2 weeks. If you have a home older than 20 years, you should consider doing an energy audit and improving your insulation. There was one recommendation we could not do which was insulate around joists along slanted walls on the second floor due to lack of access. I plan to addressing that the next time I redo the roofing. I also used this opportunity to caulk the soffits to reduce a bee issue we have (I live in the country). I have more work to do to better insulate and seal foundation joists in the basement, but at least I know what I can do to improve my home now."

"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."

"This company is wonderful! One of the things I think that is missing these days is customer service, general kindness and respect. When the guy came and gave me the quote he told me much of the team is family and the ones that are not feel like they are. You can see this is their customer service! They work efficiently, neat and I felt comfortable with them in my home! They were very polite while informing me of what they saw in my attic and what they were doing. I would highly recommend them. Friends of ours had them insulate their home last year and they highly recommended them as well! THANK YOU Church's team happy to give you all 5 stars!"
