Design Windows & Doors, Inc. is rated 4.9 out of 5 by 91.
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 4 out of 5 by from New Front Door I was looking for someone to switch out my front door for two months. I wanted to make sure I went with someone reliable, honest, and would do quality work. I’m glad I went with design windows and doors. They had my door installed in one day and it looks beautiful. The quality of the material is A grade. It’s given my house the face lift I wanted. My family has given me so many compliments. The only reason it’s not a five star review from me is the technical issues I’ve been having. The Yale app included with my keyless entry has not been working since install. It was one of the main features I looked forward to when choosing the hardware for the door. However the customer service has been amazing. After setting up the lock and noticing it wasn’t working I called Leon at design windows and doors and he tried to help me trouble shoot the problem over the phone. It didn’t fix the problem, but Leon was able to schedule for replacement hardware to be sent out within a reasonable time. I plan on working with design windows and doors again to replace all the windows in my house. Their customer service is that good.

Rated 5 out of 5 by from Beautiful Custom Sliding Door I selected Design Window and Doors because they are a qualified Milgard Representative. On September 30, 2021 my custom order was delivered. The team was excellent, extremely professional and polite and respected my historical home. The installation was upstairs directly leading out to my balcony. When the installation was completed they cleaned up beautifully. It was a good experience and I am enjoying my beautiful custom sliding door. Great job fellas!!

Rated 1 out of 5 by from Disappointing Professionalism and Service Began the process with Design Windows & Doors Inc on 3/31/2021. Salesman told us the door would take 5 months to build, all doors are custom and we agreed. They wanted 50% of the money up front.We signed the contract and handed over the check that was quickly cashed. Be very aware of what they have you sign and initial. No dates or delivery on their side has been completed as promised, and as of today, the “one day” installation was a door being installed with no door handle. The door lock was broken and we were told after already having a 4 1/2 week delay, ( including 2 appointments canceled by the company) that they would be back no later than the following week to complete work. They last day of there promised return came and went without even a phone call. After reaching out to 4 different contacts we had with the company someone did finally respond to tell us the door handle should be in sometime next week. This is a front door, not a side door we can just avoid using until the job is finished. They were prompt to demand payment for the door and receive their funds, as I sit with an unusable front door that I have paid over $10,000.00 for, this is money in their hands, they will refer you to their contract that I did regrettably signed that if I did not pay the balance for the materials at delivery they would charge me $500.00 to reschedule. I did do my research before going with this company and after such great reviews I thought they were a reputable company and the price was worth great customer service and great workmanship. As of date I have none of that. I have a door with no weather stripping, no front door lock or handle, screens that fall out of the frame when the glass panels are open, and the threshold into the house is missing and have not once been visited by any representative of Design Windows & Doors.

Rated 5 out of 5 by from Love our new Front Door! First let me say we love our new Front Door! everything went pretty smooth and I was in constant communication with the project manager Arthur. The installers were professional and did great work. I would recommend them to my family and friends.
