"Very easy to work with. The owner himself came out to give me an estimate. Mark completed the actual insulation. He was quick and he did a great job cleaning up the area after doing the spray insulation. Highly recommend!"

"Courteous, diligent, professional and fair priced. Without reservation I would highly recommend Q-insulation. They installed rock wool insulation in all the ceilings and on the vertical attic walls in our historic brick victorian. They were prompt, on time and treated my home like it was their own. Thank you Valeria and the crew."

"I contacted six companies for estimates to remove attic insulation, air seal and sanitize the attic, and blow in new insulation to R49 specs. Air-Tight's estimate was in the middle of the pack. Justin Wolfe, owner and CEO of Air-Tight LLC, gave me an estimate over the phone, answered every one of my follow up questions, and scheduled my work within the week. He stopped by at the beginning and end of the job. The crew did exactly what he said theyâ d do and were very mindful of my property. My neighbors commented on how nice they left the area. He even sealed an area under my steps and at the back of my home where Iâ d seen chipmunks enter and had an opportunity to sell more work when I asked him to check the attic above my garage but said I didnâ t need it and stayed with his original estimate. I recommend Air-Tight LLC without hesitation and am thankful I chose them."
