Swimming Pool Contractor & Builder in Hershey, PA

"Great experience from start to finish. Our project turned out even better than we thought.”

- Dan

"John Earvin and his crew gave us a beautiful, custom deck that exceeded our expectations. John and his crew were professional, prompt and incredibly gifted at their craft. We truly have the custom deck that has the envy of the neighborhood. I highly recommend them to anyone who is looking for their own dream deck. I can't thank you enough for holding my hand through initial proposal to final inspection. They even sent my daughter a beautiful bouquet of flowers for her 6th birthday. We are so grateful to Keystone, John Earvin and his crew for making our dream deck become reality!!”

The craftsmanship of their work was impressive. We highly recommend Keystone.

We had an outdoor living space completed by Keystone Custom Decks. Elmer and his crew did a great job from start to finish. The whole crew did great work, they were very respectful and did a great job communicating during the entire project. The guys were very pleasant, hard working and nice guys. Can’t tell you all the compliments by family and friends we have received on how it looks and how comfortable the deck is. It is also so functional. We are very satisfied and would highly recommend them. Thanks so much! 

- Laurel

We were amazed at their craftsmanship and overall attention to detail. Matt answered all of our questions and kept us in the loop on everything involved with the project. We didn’t have to worry about anything including the permits, inspections or scheduling of subcontractors. Matt handled it all. The entire project took about two and a half months from start to finish. The finished product is even better than the renditions. Thank you to all of the Keystone staff for making this a wonderfully stress free experience. We will enjoy our beautiful outdoor oasis for years to come.

When you hear “Hershey,” you probably think of one thing: chocolate! And that is what Hershey is best known for. It is the home of the Hershey chocolate factory, founded by Milton Hershey in 1894. 

After he started his chocolate factory in 1894, Milton Hershey founded a town for his company’s workers. He built the homes with modern amenities like electricity, indoor plumbing, and central heating. He also built a public trolley system, a school that offered free education for his employees’ children, and even a free vocational school for underprivileged boys. 

Later, Hershey built an amusement park, community center, zoo, and sports area as well. 

Hershey’s goal for his town was to provide “a perfect American town in a bucolic natural setting, where healthy, right-living, and well-paid workers lived in safe, happy homes.” 

Today, the community still thrives and attracts countless tourists per year. says this about the town and its founder, Milton Hershey: 

The town of Hershey continues to be a special place for its residents and a popular attraction for millions of visitors annually. The Hershey Company is the nation's leading manufacturer of confectionery products and Hershey Entertainment & Resorts continues to provide attractions and accommodations in Hershey that exceed guests' expectations. Indeed, Milton Hershey's accomplishments do speak for themselves.

His deeds are his monument. His life is our inspiration.
