Professional and did a great job.

Best price I found and good product, knowledgeable sales person, installation crew were nice, professional and did a great job.

Great Company to Work With

I had a great experience working with Design Windows and Doors.

Very informative and personable

My first Salesman Fausto (I think that was his name) that came out was great. Very informative and personable, the second man was nice enough and well spoken, but a little grumpy, and seemed irritated when I wasn't ready to sign up with the quoted price. But he dropped the price and we signed that day. Very fast and clean. No issues upon clean up at all.

Great communication all the way through the process.

We have recommended you to several people in the community. Because of your presentation at the Board meeting we were able as a community to go back to offering retrofit. THANK YOU! Great communication all the way through the process. Very informative. Very personable and friendly. Right on time. They cleaned up in every room-left house looking great.

The door is beautiful!

The custom door fit perfectly. Martha, Fausto, and Amy were very helpful and always available for questions. Very informative and explained the process perfectly. The men are professional and did a great job installing and clean up. The door is beautiful!

Very satisfied!

Very satisfied customer. Fausto is honest and he represents the company well. That's why we decided to hire Design Windows and Doors to install our windows. Oscar and the rest of the crews are also very professional. They cleaned up all the mess.

Did a very good job.

Very professional and courteous. Did a very good job. They forgot one of their extension cords.


Excellent! Oscar and Jorge are the best!

Very satisfied!

We are so satisfied that we have asked them to install 3 sets of windows and doors. Attention to detail from order to installation was very impressive. Always available with immediate answers to my questions. After a conflict of initial meeting schedule, the owner of the company personally met with us. I can't say enough about his knowledge and professionalism. Installation was complete in one day with attention to every detail. Great crew. Amazed me how clean the inside and outside was!

Great job!

Loved the workers, so nice and helpful. Friendly and good scheduling. Not pushy. Knew the financial part of buying windows. I recommended him Bill to someone else here in Helendale already. Very clean great guys.
