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.
