RUN RUN far away from this company. I replaced all the windows and sliding door in my home with this about company 3 or 4yrs ago. Paid roughly 20k and there has been nothing but issues ever since. Numerous delays and cancelations on the installation, installers requesting to use my restroom. Even when I thought I was done, the windows and doors started to leak everytime it rains. Save yourself a headache and go with a reliable company. This company is a joke, but im the clown thats stuck with this disaster smh.

Workers were courteous and professional. Workmanship was done quick and efficient. Any issues or questions that I raised were answered and promptly taken care of. Definitely would recommend to anyone looking for window and door installers. The Window brand they recommended and used was Simonton. After installation there was a noticeable temp difference indoors. The team worked hard and it shows. Kent and Bernardo jr. made sure really took the time to make sure I was satisfied.

We just had Design Windows and Doors put in new sliding glass doors and two large windows next to them, and the whole process was easy fro start to finish. Our salesperson was professional and helpful without being pushy, which we really appreciated. The project manager kept us in the loop the whole time, and the installers were fantastic. They made sure to protect our stucco and the inside of our home, did a great job with the install, cleaned everything up, and hauled away all of the trash. We're really happy with the results and definitely recommend them.

We had Design Windows and Doors from Ontario, CA install a number of windows and sliding glass doors in our condo. They did a fantastic job and completed all the work just as they said they would do, and right on schedule. I would highly recommend them.

Our house has lots of windows however they were all original to the house which was built in 1988. With no sunlight or UV protection, the windows urgently needed to be replaced. After shopping around, we decided on Design Windows & Doors because of their initial consultation with the owner JR. He was attentive, listened to our goals, worked with our budget to present multiple options, and was extremely up front/transparent during the process. The final product was incredible! We had 22 windows and a patio door replaced, with the windows being Simonton products and the door being Pro-Via. Our house looks and feels like a new place! The curb appeal is beautiful, the products are terrific, and we are very happy. I would highly recommend Design Windows & Doors; in fact, we will use them again for our other doors in the house in the future.

I purchased my door at the beginning of this year and in September I noticed that near the bottom of the door the paint was lifting a little from the door. I called Design Windows and Doors to see if I could get it fixed. I sent them a picture of the door. I was willing to pay anything to get it fixed and I thought it was my fault. Luckily for me, it was a manufacturing defect so Design Windows and Doors repaired the entire door for free. I dealt with Sydney and she was just wonderful. Their customer service is stellar and I will highly recommend them to all of my friends and family. It's hard to find 5 Star companies any more with such great customer service. Yay! My door looks fabulous.
