The team at Window Doctor did an amazing job. Everyone was very professional and courteous. Prior to installation, the team helped problem solve a unique situation that, upon installation, turned out great. Jeremiah and his assistant did a fantastic job with the installation. They were polite and very professional. They did a great job of keeping the job swept and clean to reduce the mess. As it turned out, we had some windy days that Mother Nature threw at us on the installation days but the two worked very quickly to reduce the amount of debris getting scattered. This was not an easy job for them and we were very pleased with their work!

My husband and I had 16 windows replaced by the window doctors and they went above and beyond our expectations! The (Cole) installer crew did a phenomenal quick and clean install. Couldn't have asked for a better crew! Thank you!
The installation crew was very clean and courteous. There was an accident during the installation of my 3 light slider which damaged the frame. The warranty offered through The Window Doctor covered that and anything else for 2x the life of the house.
