“We had our new deck and patio built by Keystone Custom Decks and they both look beautiful.  The sales team helped us design the deck and patio and connect them with a spiral stair which was a great idea.
The crew did an amazing job to build them in November.  We appreciate the professionalism, and we won't hesitate to recommend Keystone to our friends in the future."

"We recently contracted Keystone to screen in our existing deck, complete with a barrel roof.  We could not be happier with the finished product.  They delivered a first class product in a first class manner.  We are very happy!"

- Kathleen Rutherford

"Keystone built a 2000 square foot deck for us.  There was no pushy sales techniques.  We went to Keystone's showroom and made a couple of modifications.  The ending product was as presented, and we are happy with the results."

- John Bonner

"Keystone not only designed and unbelievable deck and storage room, it was actually beyond our expectations.  We will definitely be using Keystone again for some future projects that we have in mind.  It was such a pleasure to work with them, and we could not be happier with the end result."

Paul H:  "Keystone Custom Decks has been wonderful to work with during all phases of our deck project. Ron came up with some ideas based on our list of wants for a new outdoor space. We worked on those ideas and visited the showroom several times to compare materials etc. The final design was beautiful and fit our needs perfectly. All Keystone’s employees and subcontractors did a great job building the deck. The landscapers prepared the site and landscaped after the deck was complete. The concrete crew and stonemasons were excellent. The building crew, led by Reuben, was superb. Many of our friends are in construction and they all commented on the quality of work and materials. Every person from Keystone was very polite and responsive to any questions we had as the deck and patio were being built. My wife and I highly recommend Keystone Custom Decks."

Chris M:  "Overall incredible experience. From the start to the end, everything exceeded my expectations. Working with the primary point person (Dan) was incredible. He graciously listened and provided feedback on all our crazy change requests! Would highly recommend these folks to anyone. They came highly recommended from others in the neighborhood."

Keith S:  "We hired Keystone Custom Decks to build our new deck. We were replacing an existing patio. Ron did a great job of handling the process of meeting with us, understanding our needs and providing a detailed estimate. Keystone kept us up to date throughout the process and started the project on time. Ben, our project manager and his team were great to work with during the build. They showed up exactly when they said they would and finished the project before the scheduled completion date with quality that was top notch. We will definitely work with Keystone again in the future."

Stephanie B:  "We had a fantastic experience with Keystone Custom Decks! They were easy to work with and always professional. One thing we loved was how every night before heading home, they cleaned up the entire work site and stored all equipment and materials safely from the elements. Great communication through the entire process and delivered a beautiful product safely and on time!!"

Brandi D:  "Where do I start? Keystone Custom Decks provided us with an outdoor living space that changed the way our family spends time together. We've had dance parties, watched football games, listened to music and just enjoyed our morning coffee in the outdoors. We could NOT BE HAPPIER! Keystone and their crew are professional, on time, courteous, clean and perfectionists. No stone was left unturned on our project. They truly listened to our vision and what we wanted for our project and it was amazing to watch it come to life on a daily basis. Each day was like Christmas morning for me! 🙂

We are having Phase II done in the spring and I look forward to working with these amazing people again. There is no one else I would call to make my outdoor living space dreams come true. THANK YOU KEYSTONE!!!"

Amy T:  "Fast, conscientious and courteous. Beautiful deck design and expert construction. We had five estimates and their prices were reasonable (middle of the price range). The deck was beautifully crafted with high end finishes like a curved deck railing and post and stair LED lighting that really gives it custom look. I loved the CAD rendering they showed me so I could really visualize the finished product before committing to them. And they were able to build the week after I signed! Can't wait for them to build my patio next."

Alicia A:  "Words can’t describe how happy we are with our deck. After working with several contractors over the last year, Keystone was by far the best experience we have had making improvements to our home. Ron listened to our wants and needs and was able to bring it all together, giving us everything we wanted and staying well within our budget. Communication was excellent throughout and they were even able to finish our job almost a month earlier than expected. Reuben and his team were able to complete our project in record time, paying attention to even the most minor of details making sure everything was perfect. As an added bonus, every person I spoke to in the company were professional, kind, and respectful! I can’t recommend this company enough!!!"

Michael D:  "From start to finish Keystone Custom Decks have been a pleasure to work with. They are professional, courteous and do outstanding work at fair prices. The communication throughout the project (walkway, lighting and outdoor living space) was outstanding. Kevin, Danny, Matt and team were responsive and always will to offer a creative suggestion as to how to improve the overall project. I would highly recommend them to anyway looking for a deck or outdoor project!"

Jason P:  "If you are reading this, then look no further. Keystone custom decks has set the bar with how customer service should be and the quality of work that your hard earned money deserves!
Everybody was absolutely great to work with from Bradley, Ron, Dave, Kevin and of course Daniel and his crew. The attention to detail from these guys was incredible and refreshing. It's just something that is lacking in today's world. Daniel and his crew were professional, pleasant, on time, cleaned up everyday and just a nice group of guys.
They are also the hardest working guys I have dealt with-our project was built in Mid Feb to March and the conditions were cold, snowy and rainy but they got the job done. Also, any concerns I had were answered immediately from Daniel-even later in the evening via text.
Take it from me, I am very particular and want things done to perfection, and these guys made it happen! Do yourself a favor, stop reading this and call/email them NOW!
Thank you Keystone Custom Decks for building our dream patio/covered deck. We look forward to spending many quality hours with friends and family!!

Thomas G:  "I would like to start out by saying I have lived in my house for 22 years. I have had several home improvement projects from new roof, new driveway, new furnace, new bay window, etc. This year I had our deck replaced by Keystone Custom Decks. It was the most worry free and pleasant experience of any project we have had on our home. Joe, Josh and Paul who did the construction of our deck, they were amazing. From the time they came in the morning to when they left in the afternoon they were hard at work. These three men work together as a team to get the job done in a professional and high quality matter. They answered all my questions and addressed all my concerns. When the job was finished the cleaned up the area like they were never here. The finished deck was even better that what I have envisioned. This experience with a contractor was first rate! I would rate it a 10 plus!!! I would recommend Keystone Custom decks to all my friends and associates. Thanks to Joe, Josh and Paul for the wonderful experience!"

Berghuis M:  "We started our project with Ron Yoder as our sales rep. He did a great job explaining everything and provided some great ideas we had not considered. Dan and his crew were amazing! From tear down to completion of our new covered deck- our experience with this crew was top notch. They paid attention to every detail and remembered every small change or adjustment we asked for. The materials and the completed project is all high quality workmanship. The entire process from start to finish was professional and timely. Dan and the crew worked in some extreme conditions too! Ask for Ron to get started and Dan and his crew to complete the job."

Anthony W:  "I did my due diligence when shopping around for a deck builder. From the very beginning, Ron impressed me with his timely communication and dedication to working with us as we began to visualize what worked best for our house and yard. The building crew of Joe, Paul, and Josh was outstanding. They were on time, dedicated, hard working, polite, and easy to work with. They even went the extra mile and worked on a Saturday! Various neighbors on a daily basis expressed how impressed they were with their work ethic and craftsmanship. My wife and I are thankful to the Keystone team and highly recommend Keystone be a part of anyone's future projects!"

Gary F:  "I could not be more pleased with the job Keystone Custom Decks did putting a new, covered front porch on our home with new walkways as well. Keystone put a new deck on my house about five years ago that was amazing. When we were considering a new porch and walks, they were the first ones I turned to.
Everyone was exceptional to work with. Matt had very little to work with since I lack much "vision" and with a few details he designed a new covered front porch that has transformed the appearance of our house. Ray was accommodating, working to my schedule with other work being done on the house at the same time. Communication was clear timely and informative. Matt Blank and his crew were simply fantastic. I feel like they treated my house as if it were their own. They were all professional, courteous and a real pleasure to work with.
If I just had more resources and need, I'd without a doubt find another project for them to do.
I would recommend Keystone Custom Decks without hesitation!
This is a 1st class organization."

Mark B:  "From start to finish Keystone Custom Decks was professional, efficient and well organized. Everyone involved with our project knew how to get the job done and worked together in a manner that made the entire process seamless from the customer perspective. Of course the rubber meets the road in the final product and we are very pleased with the quality of the work. A special shout out to Josh G and his crew. They came to the job every day ready to get the job done, took pride in their work and listened to our questions and concerns and offered solid solutions. The sole negative was that the crew got called off for 3 days (during a 5 day job). Not the crew’s fault or a major issue but every customer wants the disruption of any construction project minimized. That said, probably one of our best home projects ever. Great company to work with and they produce a first rate product."

Jonathan V:  "Absolutely stunning! Recently completed our deck project with Keystone Custom Decks. The process from start to finish was a great experience. Overall, they were very professional, offering great ideas and solutions to our needs. They made adjustments where necessary or requested. DANIEL and his crew were great to work with. They were true craftsman -- incredible attention to detail, took pride in all aspects of their work and finished the job in less time than anticipated. They even coordinated in advance with our other contractors doing work on our house to ensure appropriate installation without duplication of effort or compromise of work done. The result was absolutely stunning with multiple compliments from our neighbors. We are looking forward to adding additional design elements to the deck through Keystone in the coming months."
