If you need quality, well made windows in your home, contact The Window Doctor. They came out and replaced my old windows with new ones. The workers were here, very respectful of my property, removed the old windows and installed the new ones and made my house feel much better. They always do great work.
The guys did really job on our windows they were courteous and they did a good job and got it done in two and a half days The rain slowed them down a little bit but other than that it was great
Ordering the windows was a breeze, they have an "apples to apples" policy so if you find a better deal with the same quality windows before a month is up they will price match. I picked the color of the outside and inside of the window and they came out two months later ready to install. The installation crew came in and courteously removed their shoes then worked quickly and efficiently! There was a phone call to be sure we inspected the inside and outside of the window, and to be sure we knew how to work them. It was at this point that they explained my favorite feature. There is a little latch that flips out to avoid the window opening enough for a person to climb in or out. This is meant for burglars, but it functions great to keep my 5 year old from opening it and climbing out! There was also a promise to return if we call and need anything warranty wise. My windows look great, are energy efficient, and work beautifully! Thank you, Window Doctor!
All of the people from Window Doctors were very friendly and helpful. I didn't feel pressured to buy more than I needed. The installers did a great job and my new windows look great. I also appreciate the warranties knowing they will fix anything that may go wrong in the future.

The installers were on time and very professional. Install was quick and easy. The result exceeded every expectations that I had. Would highly recommend this company for all of your window needs.
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!
