DP Door Company is rated 5.0 out of 5 by 31.
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 Great Service and Quality Work This is the third opportunity we have had to work with DP Door Company. They replaced the windows in a previous home and we absolutely loved the windows we selected. In our next house, we immediately replaced one slider and converted French doors to a slider. We just replaced 16 windows in the same home. We dealt with Terry on all three occasions. Terry was always helpful, engaged in the process and professional. The team that came to the house was professional, courteous and timely. They were at the house when they said they would be and finished the job on time. They kept the worksite clean. We went with DP Door because of our previous experience and they sell quality windows. I highly recommend DP Door Company to anyone who is looking to replace windows!!!
