“We were the first deck project for this company in TN and we are very happy with the outcome. I would highly recommend them as they had great communication and transparency on the process and the outcome was identical to the 3D rendering which we initially fell in love with. Great crew and Great company!!!”

“The crew was so efficient! Communication on point! Worked through coldest days and got the job done exactly as planned. Decks turned out better than expected. Can’t wait for the warmer months to enjoy! Great job by Willy and crew! Will definitely use for any future projects.”

“From start to finish, Keystone was the best contractor we’ve ever worked with. It is worth the cost for the peace of mind of working with a company like this. They took care of everything and did exactly what they said they were going to do. Great accessibility and communication. But obviously the best part was the actual work itself. We love our new pavilion and living space. The crew was amazing as they are expert craftsmen, but they are even better people. It was a pleasure to have Elmer, Logan, and Roman at our house. They were always punctual and friendly. They kept us up to date on all details, did a great job keeping the construction site clean and tidy, and always held anyone else coming in to do work to their same high standards. We highly recommend Keystone!”

Have you ever dreamed of adding more usable space to your home in Dauphin County, PA?

Maybe you wish you could host amazing parties, have space for enjoying friends and family, or just have a place to relax after a long day at work.

A new deck, porch, or patio enables you to do all these things, besides adding value and beauty to your home!

At Keystone Custom Decks we want to help you make your vision a reality. Give us a call and we would be happy to help with your project!

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!
