We had this company seal our first home and seemed to not have any problems. The owner seems like a nice guy but the techs hat came out to our brand new construction were terrible (one of them anyway), he over was kind and kept to himself and did pretty good. The main guy was condescending and rude and left a mess of drywall and whatever they used behind him in almost every room and didn't clean it up. They also damaged many door frames and ways w the ladder. For $1500 I expected consideration for my home. I would never recommend this to anyone!
