"The initial people that I worked with were great. The installer was a different story but not by fault of his own. Despite the bumps that were ran into, everything went really smoothly. Just keep in mind that installation is messy!"

"This probably the most professional service organization I've worked with in any capacity. They did a comprehensive audit and we discussed issues that could be remediated prioritized by the biggest bang for the buck and then they did the fixes we agreed upon. I always felt like I was dealing with an expert who had my best interests at heart - work that they could have done that they advised could be deferred. Ended up increasing the insulation in the attic which I'd known for years was a problem and sealing the ducts which has made a noticeable difference. I'd happily recommend Atlas to anyone who thinks they might benefit from a home energy audit and efficiency upgrades."

"I needed a company that would blow insulation into the walls of my basement. Terra Insulation did the job for me. The technicians were expert at drilling the holes, adding the insulation and clean up. They were professional and informed me of when they were taking a break, etc. They even replaced the disks and added drywall paste to ready the walls for my painter. I highly recommend this company for its dependability and expert installation."

"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."

"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."

"The team from Atlas did an excellent job of installing spray foam in my attic, adding additional loose fill in another portion of my attic, and sealing my ducts. Would certainly hire again for other insulation projects and highly recommend them."
