“Keystone Custom Decks uses a process that is customer and quality focused, thorough, and professional. The initial meeting, the quote with the drawing(s) and 3-D renderings, and the build process were all very satisfying. Work started on my deck during the week prior to Thanksgiving 2019, as promised, and it was completed on time.”

“We had a great experience with Mahlon and his team at Keystone Custom Decks. From the initial meeting to the final touches, everything was very well executed and beautifully done. Every member of the team worked very hard and they wasted no time. They disassembled our old deck in minutes and constructed a beautiful deck, with railings, gate, and a pergola in 2 days.”

“Keystone Custom Decks recently built us a beautiful new deck. The process was so easy. Our options for materials were clearly laid out and the price was reasonable. The crews were polite, professional and SO QUICK.”

“We love our new deck! The entire experience was relaxed and professional from the initial quote process with Mahlon through to the final product with Anthony and his crew of very hard workers. The gift of wine and two etched wine glasses was a lovely finishing touch!”

– Terese Genecco

“We love our new deck!  After 18 years of living in our house with an awful brick patio, we decided to get a deck.  From the first meeting with sales, Keystone was timely and professional, and a great company to work with. The project was begun even earlier than our planned schedule.  We are awaiting warm weather to enjoy our new deck!”
