Swimming Pool Contractor & Builder in York 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!!”

- Tina

We recently had the pleasure of working with Keystone Custom Decks to build a back covered patio for our home, and I couldn't be happier with the results. From start to finish, the experience was nothing short of exceptional. I work from home and was able to see how much care and patience went into placing each piece. Honestly it feels like we got a great deal! Not to mention the level of professionalism they had each day is hard to find these days. They were so kind and thoughtful of all our questions and concerns. Overall, I wholeheartedly recommend Keystone to anyone in need of outdoor construction services. Thank you, Keystone, for creating the perfect outdoor space for our home!

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! 

The time it takes to install a pool can vary depending the complexity of the project. However, most fiberglass pools take 3-4 weeks to install while concrete pools take 2-3 months to install. 

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.

Though first home to the Susquehannocks and the Lenape Natives American tribes, York County became home to German and Scots-Irish settlers in the early 1700s. The county played a vital role in the American Revolution. The largest town in the county, York, temporarily became the United States Capital in 1777. York was also where the Articles of Confederation (the first US constitution) was written. 

Like maybe surrounding counties, York experienced increased growth and industrialization with the development of railroads and canal systems during the 19th century. Home to many Quakers and other abolitionists, the county also served a vital function in the Underground Railroad.
