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.

“Working with Ron to design everything was such a pleasure, and he really helped us to gain a vision of what our new deck and workshop space could look like. He even helped us to imagine and design a balcony nestled in the roof of our new workshop space that we could use directly from our master bedroom. This is a very unique feature that we had never seen before and it has quickly become our favorite space. Ron showed us a few different tiers of construction based on different budgets, so we were able to see exactly what we were opting for in the bigger context of what all we could choose.

“Elmer and his crew were prompt and responsive. They were prepared to tackle any issues that cropped up and kept a clean & safe work site.

- Steven Kearns

“At a time when companies complain of not having the right workers, Keystone is the exception. Throughout the project every team member was hard working and pleasant. I would like to give a special shout-out to Leroy and Gerald. Keystone could not have given me two finer young men whose skill and attention to detail made the whole project look effortless. I look at their work every day and smile knowing that many good times will be shared there with family and friends. If anyone is out there looking to do a project, I highly recommend Keystone Custom Decks.

King of Prussia is a census-designated place considered to be the edge of Philadelphia. The area was named after the King of Prussia Inn which was originally built as a cottage in 1719 by a Quaker family. It was converted into an inn in 1769 and had steady business as it was about a day's journey from Philadelphia. It was almost destroyed when the state wanted to expand US Route 202. Thankfully, the tragedy was avoided due to the advocating of preservationists.

We are happy to serve King of Prussia, zip code 19406, and the surrounding areas.
