Design Windows & Doors, Inc. is rated 4.9 out of 5 by 87.
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 Impeccable Work! - [ ] Design Windows & Doors did an exceptional job with replacing our 30-year old windows. We couldn't be happier! From the initial quote (completely stress free and reasonable!) to the excellent customer service and communication from our Project Manager (yes, they really do assign their customers a Project Manager!) and to the installation, the professionalism and workmanship was superior. Our installers were true professionals and their attention to detail was impeccable. Everyone involved in this process went above and beyond our expectations. A huge thank you to Design Windows & Doors! Robert & Tammy Vaughan

Rated 5 out of 5 by from A cooler, and better looking house Thankfully I was able to have these installed at the beginning of May right before summer really started in SoCal, already I've noticed a huge difference in how cool my house is and how much better it looks from the outside. Originally it was supposed to take 2 days, but they got it done in 1 day! Very kind and professional crew. So good, I've already recommended them to a friend of mine!

Rated 5 out of 5 by from Beautiful Window recently had a my kitchen garden window replaced and I must stress how HAPPY I am with my new window. It is beautiful and the installers did a superb job. They were on time, courteous and professional. I thought there would be a lot of dust but they placed a sheet of plastic to minimize dust. When done, they did a great clean-up job. Also, Martha O was a delight. She was always courteous when calling and always returned my calls in a timely manner, She is a valuable asset to Design Windows and Doors, Inc. In addition I will definitely HIGHLY RECOMMEND Design Windows & Doors, Inc.to friends and family. THANK YOU Design Windows & Doors, Inc. Family!!!

Rated 5 out of 5 by from Good job. I had my two homes done by them.  The response was very quickly to set up a presentation. The sales reps came out with samples and choices.  Working with Martha was a pleasure. She kept me updated on timelines. The crew was fast, courtesy and efficient. I highly recommend this company.
