  • ""Our experience with Keystone Custom Decks has been exceptional. From the initial design consultations, through the construction process to the follow-up questions we have had since completion, we believe that we made the best choice by contracting with Keystone Custom Decks. Their sales representatives are very knowledgeable and their construction crew was a no nonsense team that arrived on-time, worked efficiently and diligently and produced a product that is spectacular."

  • "Wow, did we hit the jackpot when you agreed to build our deck. All we originally wanted was a replacement deck for our small 12x12 deck, and what we received was a dream deck with a covered porch and beautiful stone pillars. We would first like to thank the design consultant, Ryan Glick, for a phenomenal job of designing our desk. We were just blown away when Ryan came for our first meeting. He had samples of materials, albums of pictures of desks that the company had designed and built. At our second meeting, again, we were blown away when Ryan came with a whole 3-D design of what the deck and porch would look like. He was very patient with us as explained all the different options for desk materials, rails, stairs, lighting, etc. And, we can’t say enough about the Matt and the work crew that were here tirelessly for 2 weeks in December and January. Many days, the weather conditions outside were not ideal, but the crew was here every day from 7:30 to 5:00, no matter what the weather. We were so impressed with the professionalism of these men. They were reliable, kind, courteous, neat, and really talented craftsman. Thank you again Keystone Custom Decks. We are beyond thrilled with our deck and porch. We are looking forward to the spring weather when we can start enjoying it. We have had so many compliments on the deck and have been spreading the word about your company. We wish you all the best.

Truly an asset to your company. Will definitely share your name.
