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.

Excellent customer service and craftsmanship Approximately one year ago I contacted DP Doors for our windows and front door replacement project. I knew I wanted to work with a local company and many friends and neighbors had recommended DP doors. Shirley (office manager) was amazing and soooo patient with me !! I knew nothing about windows and front doors and after many visits to their showroom and lengthy conversations I knew they were the ones I wanted to work with !! We scheduled the project in March to be performed in late June. The installers were incredible !! They knew exactly what to do and in 4 days they successfully installed 26 windows, 2 sliders, a set of french doors, and a new set french front doors. The work was impeccable...very professional and clean !! It's been 7 months since the project was finished and after some of rain and winds we have had this winter I cannot begin to say how happy we are with the new windows and doors. Thank you DP Doors for an excellent experience !! January 23, 2015
Has help for Mobile Home Owners of cheaper and older homes in area. My 1978 Mobile HOME HAS A WEATHERIZATION problem and too much cold in the winter. So the Low-e thermal upper lower's was to place in the rear bath. Here is were the cold air collects. We may do a side door and a dual regular glass slider and replace with a French Glass Door, thermal and dual pane with privacy glass as of side carport and laundry area. Not recomended we use gas window types. December 11, 2014
Excellent company This is the 2nd time we have used DP door for our window needs ... they are very professional, clean and prompt. They deliver what they promise. Terry , the estimator did a fantastic job setting us up on replacing our sub standard existing windows and keeping our homeowner association off our backs. December 11, 2014
What a pleasure to do business with D.P. Door Co. All around great experience with D.O. Door Co. The customer service is exceptional and the quality and professionalism of their sales and install team are top notch. I am a happy customer and recommend D.P. Doors very highly. December 9, 2014
Product is great; installers flawless Installing the windows has greatly improved the appearance of my home. In addition, the windows keep the noise and the heat/cold out. D.P Door installers were excellent and very professional. I recommend them highly. October 23, 2014
Best installers; best customer service We were looking for a sliding glass door to replace an aging French door. First tried a big box store, and what a nightmare to just get a quote for what we wanted. When we went to D.P. Door, we were greeted and shown high quality products, at a VERY reasonable price. In less than a half hour we purchased what we wanted. The installation was seamless. Experienced installers, backed by D.P.Door, (not a subcontractor that a big box store is not responsible for) completed the project in reasonable time. They weren't even bothered by our "nosey" dogs!! I wish we had known about them before we replaced our windows!! I will go to them for any other door/window project that we may have. Quality of installation makes the difference. October 18, 2014
Very profesional and understanding of our needs We would diffentely recomend DP Door Company. They have replaced all our doors in our house. The new 10 foot double sliding door from Milgard they recently put in really upgraded the apperance of the house and the backyard. It is unbelievable how much more quiet it is having thisnew door.
