"From the start to the very last detail of my project the team a Keystone was very professional, detailed, responsive, and accommodating. The sales team and the install crew answered all my questions and seemed happy to take the time to explain their answer. The attention to detail was obvious and appreciated. I will be working with them again I'm sure."

"We couldn’t be happier with the outdoor living space that Keystone Custom Decks created for us. The entire process was flawless with the utmost level of professionalism. Ray Stoltzfus and his construction team were incredible, always on time and going above and beyond in communicating every step of the process. Steve Ebersole and his team of masons did amazing stone work on our fireplace, columns and outdoor kitchen. While we were excited to see our finished deck, we so enjoyed working with Ray and Steve’s team that we were sad to see the project end since it felt like they had become part of our family. Overall the quality of Keystone’s work is second to none. If you want a turnkey solution and an amazing outdoor living area, Keystone Custom Decks is the only choice."

- Michael Sisk

"We could not be happier with the entire Keystone team, process, and final product! Ron handled the initial estimate, sale, and change orders, while Ben and Jay were the lead contractors handling the installation. I've worked with many contractors and could not have been more impressed with the management, quality of craftsmanship, attention to detail, the integrity by which they operated (always courteous to all family members, human and furry), and overall professionalism. Materials and workers were onsite exactly as communicated, every day until finished. No loose ends. We installed a large screened in porch, side deck and storage unit underneath and the final product really speaks for itself - exceptional. We even had a few design changes throughout and Ben and team consulted my wife and I to talk through options. One of the very few contractors I would recommend to anyone - A+."

- Joe Kozlowski

"In doing our due diligence before we signed with Keystone, we found there were less expensive options available, but in short, we found that with Keystone, you’re guaranteed to get what you pay for. Keystone is without a doubt the best contractor we’ve worked with in multiple decades of home ownership. We’ve learned through our many years of business experience that the best materials, plus the best process, plus the best people, leads to the best outcomes. Keystone nailed it in all aspects of creating our outdoor living space. We started with a well thought out and coordinated design/plan, but were also given the flexibility to tailor different aspects as we saw it coming to life. Throughout the entire process, we were kept well informed of what was happening and what would happen next, including excellent coordination with both Keystone subcontractors and others that we had hired ourselves. The materials and craftsmanship are second to none, but what stood out even more for us was the team that we spent the better part of ten weeks with. Elmer lead the way as project manager with Jeremy and Leon making up his core team. Others were added as required. Whether it was his team, his subcontractors, or our subcontractors, Elmer treated everyone as a respected professional as he brought together their various roles/expertise in to a well orchestrated and executed plan. The entire Keystone team showed up early every day, and stayed late many days, working diligently all day, striking an impressive balance between productivity and quality. It was clear that Keystone would not consider our project complete until every last detail was attended to, and we were 100 percent satisfied. We absolutely love our outdoor living space and would not hesitate to use Keystone for any and all future projects."

- Steve Nudd

"The Keystone team did an incredible job making our outdoor living dream come true! Ron Yoder provided insightful design ideas, and Johnny Lapp and the entire crew built a beautiful outdoor space that we will enjoy for years!"

- Daniel Condrasky

"We used Keystone Custom Decks for our deck and patio replacement and expansion project. Unlike some other companies we contacted for estimates, they came prepared with ideas and suggestions for how to create the outdoor space we were thinking of, including things we never would have thought of. When it was time for construction John and his team were great - polite, pleasant, and always available to answer questions and keep us in touch with progress and timelines. The whole experience was professional and of high quality and we are very happy with the results. We would recommend Keystone to anyone."

- Joe Kerkering

The Cumberland area was originally settled by Scots-Irish immigrants in the 1730s. The early settlers were mainly farmers. Much of the area is still comprised of rich farmland today. 

In 1750 Cumberland County was officially created from Lancaster County and named for Cumberland, England. Carlisle and Shippensburg are the oldest towns in the county, each with a unique history all its own. Another notable historic site in Cumberland County is the Middle Spring Presbyterian Church, located near Shippensburg. It was built by original settlers in 1738 and still stands today, as one of the oldest houses of worship in central PA. 

Today, Cumberland County covers 550 square miles and is home to some 255,000 people. It is also home to several colleges, including the U.S. Army War College. 

Cumberland has two military operation facilities as well: the Carlisle Barracks/U.S. Army War College and the Naval Support Station in Mechanicsburg. 

The Cumberland County homepage describes the county like this: 

Named for Cumberland, England and founded on January 27, 1750, Cumberland County is located in South Central Pennsylvania. The County landscape is comprised of urban communities and rich farmland. It spans 555 square miles, with more than 250,000 residents living in its 33 municipalities. Within a two hour drive or less of Philadelphia, Baltimore and Washington and within a ten hour drive of over 50% of the population of the U.S., the County is home to six colleges and universities including the US Army War College, Shippensburg University, Dickinson College, Penn State Dickinson School of Law, Central Pennsylvania College and Messiah College
