“It was a great experience working with Keystone from start to finish. From conceptualizing the project, figuring out the design and then the actual project construction. We love our new deck/screened porch. We loved working with Ron Yoder, who patiently helped us figure out what we wanted and how it would all work out. Our construction crew, Dan, Merv and Gerald were meticulous, professional and polite. We looked forward to seeing them each morning. They were extremely detail-oriented, worked with perfection, and were fun to have around. Their breaks were short and they always put away stuff and left things in good order at the end of the day. We recommend Keystone wholeheartedly.”

– Gunita Grover

“We are so happy with our new deck and patio. The crew at Keystone were professional, friendly and showed up in the snow, rain and cold weather, whenever feasible. We never had any doubt about their attention to detail or the quality of work. Both are excellent! The team also made some suggestions that we hadn’t considered ahead of the project beginning, but have made such a positive difference to the finished product. Communication was great too. We were always kept in the loop and aware of current and next steps. We couldn’t give a stronger recommendation for using Keystone Custom Decks!”

– Kathryn Wallace

“We had the best experience with Keystone Custom Decks which began with our salesman, Ron and the incredible design created for our home. Daniel, Merv and Jerald were our crew. A huge shout out to them! They provided amazing craftsmanship and attention to detail. From the first day to the last day, the project went smoothly. Daniel was the utmost professional in managing everything and keeping us abreast of the timing to build the deck, complete electrical work and masonry. If you want an extraordinarily beautiful deck to enjoy, I highly recommend Keystone Custom Decks.”

– Fran Collins

“Keystone did a wonderful job designing and constructing an outdoor space that our family will enjoy for years to come. The construction team, led by Jeremy, was very professional and always responsive to our requests and questions. We are so happy with the final product and would highly recommend Keystone for any outdoor project.”

– Stephanie Montag

“We had Keystone Custom Decks install a porch over our deck with a fireplace. I cannot tell you how happy and pleased we were with their workmanship, timeframe, and communication. After trying to secure local contractors and not receiving call backs, we called Keystone after noticing one of their trucks in our area. They called back within a day and had us scheduled for a meeting at our home. After the meeting, they invited us down to their showroom to present a rendering of what our deck would look like complete. Wow – this was extremely helpful. They scheduled the construction and stuck by their estimated date! Everyone from their scheduler to the mason workers to each and every crew member – kind, considerate and professional! I highly recommend for any patio, porch and now pool projects! You will not be disappointed!!”

Dauphin County is a beautiful place, and there are plenty of good reasons to make it your home. After all, there are plenty of local attractions in Dauphin County:

Hershey’s Chocolate World
Pennsylvania State Capitol Building
The National Civil War Museum
Wildwood Park
Pennsylvania Fire Museum
The State Museum of Pennsylvania
Hersheypark
Hershey Gardens
Pennsylvania Farm Show Complex and Expo Center

And plenty more. Encompassing the state capitol, Hershey, and lots of beautiful countryside, Dauphin County is a great place to explore! You can also find lots of great outdoor adventures in the area, including hiking, swimming, fishing, biking, and boating on the beautiful Susquehanna River.

Located in Central PA, Dauphin County is a part of the Harrisburg-Carlisle Metropolitan area. It formed from part of Lancaster County in 1785 and was named after the Dauphin of France.

Today, the county covers 558 square miles of land and water and is home to almost 300,000 people.

Besides the state capitol and Hershey chocolate world, the county is also home to Three Mile Island Nuclear Generating Station, the site of the ominous 1979 nuclear core meltdown. The plant is now closed.

Dauphin County, on the other hand, is very much alive! Dauphincounty.org describes it like this:

This capital county’s 525 square miles and 40 municipalities each have their own local flavor. Situated within a short driving distance of Philadelphia, Pittsburgh, Baltimore, Washington, D.C. and New York City, the region contains the best of both worlds-both cosmopolitan chic and down-home country.

Like the glistening, mile-wide Susquehanna River at its western border, Dauphin County is a dazzling place to live, work and play. It is paradise for history-lovers, nature enthusiasts, nightlife-lovers, sports fans, high-tech companies, families and anyone who appreciates the county’s signature “clean-and green” lifestyle.

We hope the area continues to grow and thrive for generations to come!
