Retro Green has been the best insulation company! Oren is amazing with his attention to detail and thorough inspection. He was able to find all the issues with the insulation in my house and quoted a reasonable price. Nick and Crew came out to install the foam insulation into my slanted ceilings and fix a bath fan. They were respectful and hard working. Nick showed pictures of their work afterwards. Overall, was the best experience I have had with any contractor. I have had many! Thank you for being a trustworthy company.

I had RetroGreen do the insulation in my attic and walls. I can already feel the difference with cooling and I have less humidity.The installation crew was top notch. All so professional, kind and informative. The cleanup job they did left my attic space and stairs cleaner than when they started.I couldnt tell where they removed the siding for wall insulation. They were careful working around the garden and flower bed areas. Couldnt tell they had been there!I would recommend this company for insulation.I am looking forward to lower heat bills this winter.

Thank you Jen for sharing your experience with use finding many details that were missed by another spray foam contractor that undermined the true potential for the performance of your home. We were able pin point the exact areas that were missed creating a huge missed opportunity. we were able to cut another 30% of leakage on the home with touching up the spray foam and injecting all of your existing walls with Retrofoam in St Cloud

Had foam insulation installed in virtually all my house in April & May, 2025. My project took a little longer as we ran into a couple of glitches. House was cooler this summer and am looking forward to a warmer winter. Noises from outside has definitely been muffled (i.e. traffic noises, noises from storms) Crew was courteous and helpful. Would do work with them again if the need arises.

Very professional- and our basement is already so much warmer. They found a wall with water damage we did not know about so we were able to fix that. Highly recommend
