DP Door Company is rated 5.0 out of 5 by 29.
Rated 5 out of 5 by from I highly recommend DP Door Company. We recently replaced eight windows in our home; quite the project. DP Door Company was wonderful to deal with from start to finish. We went to DP Doors because they had completed an emergency replacement for us a few years ago and they did an outstanding job. Again, they walked us through our options during this recent job, and were patient and helpful. I was skeptical that they would be able to complete the job in one day - eight windows (two large sliding doors), as they told me; however, to my happy surprise they were able to get it done. Their team was extremely professional and kind. They were prompt, hard-working and careful to not make a mess. In fact when they left you would never have known they were there (except for the beautiful new windows, of course). I would highly recommend this contractor to my friends and family.

Rated 5 out of 5 by from Friendly and prompt. We have used DP Door Company many times, for our residence and for our rental. They show up when they say they are supposed to and complete the job in a timely manner. I would recommend them to anyone.

Rated 5 out of 5 by from Outstanding service and installation We had the sliding doors (2) and windows (9) on the South side of our home changed to Milgard products by DP Door Co. and am very pleased with the products and the work done by the DP Door crew. This makes the 7th home we have used Milgard windows in and cannot be happier with the results. We would highly recommend DP Door Co. and the Milgard products. Looking forward to replacing the rest of the windows in the home.
