"They did a great job. Had a small bump in the road at first, but they bent over backwards to make everything right. Matt is great and followed up every step if the way. I love my new attic storage and finally have decent insulation!!! And the guy who patched the ceiling wasn't horrible to look at, so that's always a plus!! :) They were really great about cleaning up and gave me some awesome tips for some DIY stuff I wanted to do. I tried to stay out of the way, but couldn't resist asking a couple of questions here and there so I wouldn't completely screw up my house when I got brave and decided to do something myself!! Would definitely recommend them and will call them again when I have another big project that I need done."

"These people are great. On time, extremely clean, very professional. They cleaned out the old insulation from our attic, disinfected the entire space, sealed any holes, placed covers over all recessed lights in the attic to prevent heat loss from the second floor into the attic, and weather stripped the pull down stairase into the attic to prevent heat loss there as well. We used cellulose insulation which can be very dusty. Not with these people. They cleaned everything including the driveway. They are superb."

"Sean came to my house conducted the service refrainment. He was very professionally checking each of the room temperature, he checked the compressor, and also did the attic inspection. There were some issues that need to fix, however, due to the age of the house, I decided not to waste the money, I will wait until failed and replace a new one. Thank you Sean & HVAC Florida."

"I was not impressed with the service I received from this company. The technician was not very knowledgeable and was unable to fix the problem with my air conditioning system. I ended up having to call another company to get the job done. I would not recommend this service."

"Recently discovered some missing shingles on my roof, I called Semper Fi out for an inspection. My roof is old and needed to be replaced, so they provided me with an estimate and very soon after my new roof was being installed. Job very well done. Semper Fi has my word!"

"Definitely choose Terra Insulation! Josh, Dylan, and Brandon were all fantastic to work with. They removed existing insulation in two attics that was covered in mouse droppings, sanitized both, added baffling, sealed holes, blew in cellulose insulation, and sealed all entry points. They explained all the options and pricing clearly, gladly answered my MANY questions with patience, took care of the rebates with the utility companies, which significantly reduced the total cost, were super flexible with scheduling, very clean, and professional. There were no surprises or hidden costs. I was extremely happy with Terra's workmanship and professionalism and would hire them again without question."
