"Highly recommend. Exceptional and professional service from their contractors and most especially by Nolan Walker (Performance Consultant). Nolan showed photos taken of my home's ductwork and insulation and provided a list of options and the cost of each project so that I could make a well informed choice of which projects to pursue. He took his time and was honest and understanding - not aggressive like other companies I have dealt with. His test-out and follow-up appointment was just as thorough. It was a pleasure working with him."

"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."

"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"I would just like to thank this company for the work they did in my home! Iâ m very late writing my review but I wanted to see how different my home felt since having this service. Complete Home Solutions serviced my house on November 20, 2020, The crew consisted of Brad, Jason, Aaron and John B. There was another individual who did my drywall work, but I didnâ t get his name. There are no words to describe how much I appreciate your professionalism, knowledge, experience, cleanliness, kindness...etc. You guys did such a wonderful job! Since getting insulation put in my sonâ s room, I can feel the difference, a huge difference!! Also, I would like to thank Noah for the first initial visit and explaining to me in detail about the difference in the products. If youâ re looking for a company to provide service to your home, thereâ s no need to look any further! Iâ m looking forward to hiring them again, for my crawl space."
