I got foam wall insulation done in all external walls. The job was well done professionally and all in 1 day. Great cleanup as well, and I can already notice the difference in how much more quiet it is inside the house. Great job, thank you!

RetroGreen insulated my attic and did a fantastic job. From getting the estimate to finishing the job, everyone was polite, respectful and easy to work with. Nick and his crew worked efficiently without any issues and left everything clean and in place. Thank you RetroGreen. You were a pleasure to work with.

I contacted this company to evaluate my insulation in my garage and attic. After reviewing the insulation in my garage, my technician Chris, said that all I had to do was seal my firewall. I politely asked him to take a look at my attic insulation. He refused, stating that he had already found the issue. I asked him again; I had already opened the attic access and set up a ladder. He again refused.
After going into the attic myself, I found that I had 2 vent fans that had become disconnected as the cause of the initial damage and my insulation needs to be upgraded. He essentially left the job undone, despite the ease of access.
I will never go through this company again.
