Swimming Pool Contractor & Builder in Havre De Grace, MD

"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!!”

A perfect screen room/deck project was completed at my home last week. The job took two short weeks, from tearing down the old deck to cleaning up the property on their last day here. Elmer Beiler and his crew (Logan, Gerald and Roman) did an incredible job. These gentlemen are talented, skilled, professional, considerate, friendly, respectful, and kind. I was in awe every single day watching them work together. If I do another project with Keystone, I will insist that Elmer and his crew manage the job.

A Storied Past on the Chesapeake

Nestled at the mouth of the Susquehanna River and the head of Chesapeake Bay, Havre De Grace boasts a rich history that dates back to the early 18th century. Its name, French for "Harbor of Grace," was bestowed by General Lafayette in the 1780s, reflecting the town’s beauty and strategic importance. Over the centuries, Havre De Grace has been a witness to American history, including a raid during the War of 1812 that left much of the town in ashes. Today, its vibrant history is preserved in numerous museums and historic sites, making it a captivating blend of past and present. The town's commitment to preserving its heritage while embracing the future makes it an ideal place for residents who value culture and history.
