Swimming Pool Contractor & Builder in Delaware County, 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!!”

Wonderful experience with Keystone. Ron Yoder took his time to sit with us and help plan out the exact outdoor space we wanted. John Ervin and his crew’s craftsmanship was excellent and they kept an exceptionally clean work place. Pricing was fair and we were not surprised with any change orders. Just an overall fantastic experience. We cannot recommend Keystone enough we use our space almost every day! Thank you so much!

An average size for a home swimming pool is 16x35 or 560-600 square feet. Depth varies from pool to pool and depends primarily on the owner's preference. 

Yes, a swimming pool can easily be incorporated into a deck or patio. If you'd like help with envisioning this or brainstorming, our design team is happy to help!

Anyone that ones a swimming pool and has young children should be careful to protect their children. You also need to know that there is a risk assumed with having a swimming pool. 

However, there are several things you can do to make a swimming pool more safe for children: 

1. Put a fence around your swimming pool

2. Add a safety cover if possible

3. Alarms that sound when a person or animal enters the pool.

4. Self-locking gates

5. Gradual slope from the shallow to deep end of the pool. 

Pools are fun no matter what shape they are in. And sometimes, people prefer specific shapes for certain reasons. 

However, rectangular pools are usually considered the most versatile and are the easiest to add pool accessories like water nets.

Read Reviews From Customers In Delaware County, PA:

Joanne A:  "Keystone Custom Decks is top notch! After meeting with Ron Yoder, there was no doubt that they could make our project come to life. Thank you Ron, for everything. We are so incredibly happy with our experience with this fine company and highly recommend them to everyone who is considering a backyard transformation. Their attention to every single detail and their superior workmanship is by far the very BEST! Our site manager, Steven, and his team of Jay and Willy were a pleasure to have here every day. They arrived at the same time every single morning and worked continuously all day, and cleaned up after each day. Thank you Steven, Jay and Willy for your outstanding workmanship and top notch professionalism! Thank you to everyone else behind the scenes at Keystone who helped to transform our backyard into more than we ever dreamed of!"

Hayler O:  "We had a pergola installed over a portion of our deck yesterday. The crew arrived right on time. They installed the pergola in a timely professional manner. It looks beautiful and really enhances the appearance of our home. And the price was significantly less than other estimates. The crew cleaned up afterwards. Nice group of men. If I need any deck work, this is the company I will call."

Ryan D:  "We put up a pavilion in the back yard and did a flagstone front walkway. Levi, Steve, Amos, and Eric were in and out in about 8 working days. The guys show up early and stay late. Left a very clean site every day, and worked with us on changes. All of the little details were taken care of and they did 100% of the job in a timely fashion....something that is unfortunately rare when hiring contractors. I would recommend to anyone and hire them again for any project."
