"These guys are the definition of professional. Always on time, always communicating, always respectful. We did a 1,000SQF composite deck with a screened in section, heaters, lighting, cable railing...the works and it all came out awesome. The attention to detail was incredible. You'll never hear a curse word or see a cigarette butt in your yard. We had the pleasure of having Anthony and Ernest as the primary foremen, but the whole team is incredible. I was honestly sad to see them go because it was such a pleasure to watch their progress! Strongest recommendation of any company I've worked with over the years on home projects!"

- Trevor DiMarco

"I've never dealt with a contractor that was so responsive, and stuck to their timeline. They came every morning and told us the schedule and stuck to it. They went above and beyond, and answered all our questions through the process and revised the project when we asked. We highly recommend Keystone for any outdoor projects."

- Kyle and Agatha Edkin

"They came highly recommended, but we still couldn't be more pleased with our experience with Keystone Custom Decks. From design, to planning, execution, and clean up, the team exceeded any expectations. All team members were kind, hard-working, courteous, and professional and they do amazing work! We are thoroughly enjoying our new backyard and felt really great about working with this superb business that made it all happen."

- Holly Hindman
