Greg Walters:

“The Keystone team performed at every level. From prompt and courteous sales, into design/quote, build prep, demo, construction, masonry, and final fit-out. We had four to five teams on-site fit out at various or the same times. At every level, the process was explained, checked, executed, and checked again. I liked the company but loved the crews who day in and day out worked very hard to give us what we hoped for and more. Top-notch service and execution.”

Tom P:

“From the beginning to the end of our project, everything was handled very well. From meeting with Joe to the artist renderings to obtaining our permits, everything was handled very professionally. It was our pleasure meeting Daniel and his crew Arlan and Ivan and watching them create our dream outdoor space. Daniel patiently listened to our ideas and implemented them where he could. I would also like to thank the Masonry crew, Stonework crew and the landscaping crew that reseeded our yard. Keystone Custom Decks exceeded our expectations.

“This past spring we had Keystone construct an addtion to our patio that included new roofing, pillars, and serving counter space. The crew led by John Fisher did an outstanding job of installation, communication, and attention to details. They also constucted a new entrace Roof area to our home. This has dramatically changed the overall look to our home. I suggest that before you make any decision to construct a new outdoor space, visit the showroom of Keystone. Let them create the drone overview that we were able to see and visualize what our home would look like post install. They hit it out of the park and we are greatful for the care and time they took to deliver an above average project.

“Thank you, Keystone, Daniel, Elvin, Wayne, and teams, for the wonderful job you did on our backyard project! Our patio, porch, and sunroom are all amazing and add such great living spaces to our home that will bring our family joy! You've truly made our dreams a reality! We appreciate you and your craftsmanship!

- Therese Brooks

I couldn't recommend Keystone enough. They built my deck in 2020 and now a new walkway and portico this year. The work is high quality and both construction teams have been stellar in their work and character. Skilled, kind, and respectful. Arlen was great on this project as was Ray who handled the masonry. The whole team is great and the office always responds promptly.

History of Harford County

Harford County, established on March 22, 1774, was formed from the eastern part of Baltimore County. It was named after Henry Harford, the last Proprietary Governor of Maryland and the illegitimate son of Frederick Calvert, 6th Baron Baltimore. The county played a significant role during the American Revolution, hosting the signers of the Bush Declaration in 1775, which called for independence from British rule. Havre de Grace, a city within the county, was once considered as a potential capital of the United States due to its strategic location at the top of the Chesapeake Bay​ (Wikipedia)​​ (Harford County MD)​.
