"Gus (owner) came out to provide an estimate. He was in the attic for about a half hour looking over the space so that a complete estimate could be provided. Several weeks later Gus came out and added blown in fiberglass insulation which made the area an R-60. While Gus insulated the attic, he took pictures on his cell phone and showed me the completed work."

"A few years ago we had our attic re-insulated and this past spring we had a new roof put on our house. After the roof installation we noticed some nail pops in our ceiling (we have trusses) and as a precautionary measure I contacted AtticAir for an attic inspection to make sure that the insulation was ok as well as the proper attic ventilation was installed. Steve was prompt (appt was at 4:00 and he arrived a few minutes early), thorough and best of all said there was no work to be done. He explained everything that was up in the attic and that everything was up to spec, airflow was fine, attic fan was working and that there was no need to spend money up there!"

"Dan did a great job showing me all of the ways my home was losing heat in the winter and then fixed the issues. Really nice guy, informative, hard working. Not only did he install lots of insulation he also sealed cracks, vented bathroom fans, sealed up an old kitchen fan, etc. He showed up as promised and completed the work in a very timely manner."

"Fast work. Great communication up until trying to communicate with project manager. Was told everything would be completed within two days. The roof was done in one which was awesome, but I am still waiting on gutters a week later and won't be given a day/time for them. Just keep being told "early next week" or "tomorrow". Sales portion and inspection went great. Fantastic everything up until the install."

"George came out promptly and did a thorough inspection of the crawlspace and provided options on what can be done. The insulation work was performed by Jesus who also found and fixed two foundation cracks. Encapsulation was done by Juan's team and they all did a great job. They were able to perform all the work with a very narrow opening into the crawlspace and were also able to fit in the dehumidifier. After installation there was a minor issue with the dehumidifier and Craig came right away to fix it. Great experience and I'd definitely use their services in the future if need be."
