Fantastic! Romeo and Efram were prompt, explained everything, and showed me exactly what they were going to do. My attic was a disaster, the insulation had been ripped to shreds, there were animal feces everywhere, if I remember correctly there was also a dead rat up there somewhere. The ducts were old and ripped and worthless as far as maintaining a consistent temperature in the house. it was absolutely disgusting. They really had to work their butts off to get it all done right. They put up plastic to contain the area so no particulate escaped into the air and contaminate the rest of the house. They showed me the insulation and explained how it was being put in. They explained why they put in disinfectant, and what type of disinfectant they use, that it was all natural and nontoxic. (I even looked online to see how well it worked - reviews were great) They cleaned all debris so thoroughly it didn't look like we had any work done. It was awesome. After a few hours, when it was done they had me go up into the space and, WOW, it looked brand new. I was floored. When we turned on the a/c and the heat it didn't feel like each room was a different temperature zone, everything worked perfectly. My husband and I were thrilled. Honestly, you couldn't find two more professional and lovely gentleman to have work in your home. I have already recommended Attic Masters to four of my neighbors because I have so much faith that the company and their employees will do a professional and thorough job. I love this company and couldn't be happier.
