Design Windows & Doors, Inc. is rated 4.9 out of 5 by 57.
Rated 5 out of 5 by from Putting "service" in Customer Service I was replacing all the windows and doors in my home at one time and in having 5 different companies bid on the program, I learned that not all of them do window AND door sales and installation. Design Windows & Doors does and from the time I contacted them they were always professional, courteous, and timely with their follow-up and on-site appointments. The entire project was completed from 9 a.m. - 3 p.m. including the work area clean up and the hauling away of old materials. The installation was done well, and my home looks like a newly built house now.

Rated 5 out of 5 by from This dealer by far has the best customer service! We highly recommend them. We are throughly pleased with our window's from Design Windows & Doors, Inc. ; The worker/employee's are all are professional, yet caring and concerned. We can't believe the difference in our home since the windows were installed. Our home is brighter and appears to be more open. Great investment!!! Many company's gave us estimates not one could compare to this dealer. Yes, we highly recommend this company. You will not be sorry just overjoyed!

Rated 5 out of 5 by from Very pleased What a wonderful crew- because our house is block and the old windows had steel frames it took them 12 hours but they still cleaned up beautifully and were respectful of our space . I loved walking around and easily opening our new windows because our old crank windows were ......cranky!

Rated 5 out of 5 by from Had to get more windows!! I was only replacing the windows that needed to be replaced. After the transformation I order the rest of the windows for my house. I have a custom Log home in Big Bear Lake. All the log trim is hand carved around the windows and doors. I was very worried about the installation, but David came to my rescue!!! David installed my windows like a millwright pro!! Amazing workmanship!! It went so great I felt it time to do all the windows and David is our installer or no deal! Thank you Design Windows !! We love our New Millard windows!!
