Wonderful

Sandra L.

I want take the time to appreciate all your hard work as a team. It started out with the boss Joe who gave me a reasonable estimate.Then came Michelle my project manager which she communicated the whole time with great customer service. Finally the 4 workers that came to my home showed up on scheduled days were always right on time which is a big deal for me l, they came in and got down to business, they were very professional and finished installing 5 sliding doors 8 windows in 2 days both days leaving everything absolutely clean they also took the old sliding doors and windows. I had an amazing experience thank you to all of you that were part of my project. Will definitely refer them.

The whole process was great. From Bill the salesman who advised and showed me what I was buying. and Michelle my coordinator was really great to work with.Very happy, friendly and upbeat, she updated me weekly on the status of my windows. Also the installation was done on the date promised. Michelle was wonderful.She even contacted me after the installation to make sure I was happy with everything. The most important part was the Installation crew. I haven't seen a crew more organized and efficient, thorough, and clean than this group of men. In the end I have nine beautiful new windows in my mobile home.The finished look is perfection. I couldn't be more happy. My home is much cooler. No more hot glass. Thanks to all involved in my upgrade.

Impeccable Service

Robert V.

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

A cooler, better looking home

Kevin G.

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!

BEAUTIFUL KITCHEN WINDOW

Gina V.

I 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!!!

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.

LOVE MY DOORS!

Pamela M.

This company is not only very professional they are very nice, calls are returned quickly, installers work nonstop and within Covid guidelines . The French Doors are beautiful and the quality is much more than I expected. A special thanks to Brianna Flores for getting those last minute changes done for us! A great experience working with this company.

Patio door installation

Juan P.

Design Windows & Doors did a great job. They replaced a window with a patio door and it looks amazing. Martha the project manager kept me informed since the begging of the project. The installation crew were very professional and attentive with what I wanted. I would definitely use them again for any project needs and recommend them to anyone.
