I was very pleased with the initial visit. Clint was very informative and fact based with his suggestions to correct my concerns with the house. I could feel the difference within one day of completing the job.The work crew were respectful and polite. I will definitely use this company again and have already referred them to help my parents.

Mike and the whole team at Green Factor Insulation were great to work with. I'm currently working on building a tiny home on wheels, and of all the various contractors and companies that I've spoken to and worked with for sourcing materials and having services completed, Mike and the team at Green Factor have hands down been the best to work with. Their costs were very competitive; their quoting process was easy, informative, and transparent; Mike had excellent communication skills; and he went above and beyond to make sure that I was going to be happy with the end product. The day of the install, Mike, Matt, and Eli showed up promptly, they were great to interact with (it's apparent that they have a great group who enjoy their jobs), they took the time to answer all of my questions, and they did a great job installing the closed-cell insulation. My home was clean and tidy when they left, and I can't be happier with the end product. I'm really glad that I went with Green Factor, and I'm happy to add mine among so many other great reviews. If you're looking for a quality installer for insulation, definitely give the folks at Green Factor a call up. I'm really happy that I did.

Great group! I was impressed with their friendly, professional attitude. They had solutions for my imperfect, incorrect DIY attic insulation efforts in an older home. They are already in my contact list for future insulation projects.

Being new to this house, I notice the attic was lacking in insulation in many areas as the original installer of the insulation cut several corners. This fact was further accented as I wanted R60. I researched SEVERAL different companies and did not let onto my knowledge and experience of being a very handy homeowner; there is not much I cannot do around the house. Green Factor was the preferred choice even though they were not the lowest price, but they were the RIGHT choice. And yes, their pricing is very competitive. After hearing and understanding my needs, concerns and expectations, they did their analysis and provided me a list of options to consider, while also weighing in on the 'value' of each option. We agreed to have a foil-board (my verbiage, heat-cold reflective board) placed onto a knee wall while spray foaming all fan-light boxes in the attic, and ensuring all soffit baffles were clear and open. Insulation was also blowin in (fiberglass-like, not cellulose) and pictures were taken as the work progressed. This was valuable as I have a hard-to-reach cathedral ceiling area Lastly, they additionally provide a pre- and post home pressure test to understand the amount of 'sealing' was accomplished; ending pressure denoted approximately 1280 (sweet spot is 1200-1300). Their attention to detail, patience and approach is nothing but stellar, and I would hire them back in a flash. I've already recommended them to several friends and neighbors. I cannot be more satisfied or happy. If you are looking for an honest, hard working and quality installation, THIS IS THE COMPANY. THANK YOU Green Factor!
