"The mold problem in my basement was so bad that the mold accessor told me not to go in the basement anymore and to see my DR. Thats how bad it was. I interviewed 5 companys and the one thing that made me choose Home Healthy Homes is Glen was the only one who told me tape the basement door so that the bad air doesnt come in the kitchen. That made my decision. His men were prompt and courteous. On the 2nd mold assessment there was one small part that didnt pass so I called Glen and he sent the crew back to fix the problem. I then called the accessor and on the 3rd assessment he said the basement was mold free and the air quality was excellent. I was finally able to remove the tape from my basement door. Bottom line, I now have a safe basement for my children and grandchildren."

"Very professional and fixed the cracks in the garage the best that I can tell. Expensive fix but well worth going with the carbon fiber, you get a 15 year transferable warranty with it. Only deducted half star because they didn't show up on a modified scheduled date."

"I got a note on my door the night before they were going to show up saying that I needed to trim the bushes on the side of my drive way. This was never mentioned during the quotes. Then I was told that some tree limbs needed to be trim but they would take care of it. They cut them and left them on the side of my house. They also cut many sprinkler lines. I was told that they would leave them up so I could fix them. The guy put them deeper in the ground than they originally were. Not very happy with them."
