Kris Armstrong: "Our thanks to everyone at Keystone Custom Decks that made our dream deck come true. Thank you Mahlon for your design ideas at the start and continuing guidance throughout the project. The construction crew was always on time and ready to work. Always prepared at the beginning of the day and cleaned up at the end. They are all very experienced and like what they do. Thank you Anthony, Brandon Steve and Jason, you are true professionals.
Completed ahead of schedule, the project was well planned and expertly constructed.
We love our new space and highly recommend Keystone Custom Decks."

P: "My first words after seeing my finished deck were, "No one has ever built something so beautiful for me...!" My deck is absolutely stunning! From the first reach-out to Keystone Decks, to the final end waving goodbye to the builders when it was finished has been nothing short of professional, quality, hard working, thorough, swift...I could go on and on! Mahlon was awesome to work with, answering every single email timely, keeping communication always present, simple yet informative. When the builders showed up to start, they did nothing but work so hard from beginning to end (in the WORST weather, too!). They are sooo skilled, swift, hard-working, efficient, focused (Kevin, you and your crew are absolutely the best guys EVER...they do not pay you nearly enough!)....and the deck! WOW! Albeit, my deck is a simple 12x20' rectangle, it is the most beautiful thing "anyone has ever built for me..."! Next to it's stunning splendor, my favorite thing about it is how SOLID it is! No noise, no give or movement, the quality is top notch! I will love my deck for years to come.....no more staining, no more rotten boards to replace, no more high maintenance...just a beautiful deck to enjoy summers with my family and friends with a stunning view! Thank you Keystone......outstanding job! I highly recommend the Keystone team for your next build! Where is the 10 star button....???"

John Brisbois: "Keystone Custom Decks is the best contractor we have ever dealt with. From initial contact with Mahlon to project finish and cleanup, they were responsive and professional. It’s amazing how fast they completed our deck project along with the excellent workmanship. Kevin and the crew showed up early in the morning and all members stayed busy all day. Whenever a decision needed to be made in construction, they kept us in the loop. We will be recommending them to others and will contact them if we need something else that they can do."

Chuck Raniewicz: "Keystone Decks has to be the smoothest running operation I've seen. I hired them to build a deck and they did absolutely professional work from beginning to end. I've hired many contractors over the years as I am a landlord with several properties. Only Keystone Decks was as courteous and professional as I had hoped. From the early planning stages to the ending finalizing stages, they never disappointed me in any way. Each day, Kevin and company would show up on time (driving from over 1.5 hours away) and immediately get to work. There was a calmness about them I've not seen on any other crew. Each person knew their job and set out about it as soon as they showed up. There was great respect for the job they were doing and the interactions between the workers themselves were remarkable as they are absolutely courteous to each other (not to mention how courteous they were to us!). They were very easygoing about last-minute changes and simply focused on doing the best job possible, which they did. Mahlon was extremely patient and courteous and responded to each inquiry quickly. He actually did the initial measurements in 2 feet of snow and it never even appeared to bother him in the least. He relayed all my information and instructions to the crew without a flaw. I wish I could hire them for every contracting or building need. Every company should operate the way they do. I cannot recommend them enough. They even sent a small Thank You gift which is absolutely unheard of but was very thoughtful and appreciated. I see only great success in their future."

Priyanka Sen: "If I could give Keystone 10 stars I would. This was the most seamless process I have ever experienced with a contractor from start to finish. Mahlon was awesome when he came to do measurements and was super clear about all the different options we could get on the deck. He also helped us get to our target budget, but still have a beautiful deck. The only downside (no fault of Keystone!) was having to wait for the deck to be built because the permitting process was backlogged. But Mahlon was very honest about this in our initial meeting and still provided an accurate start date of late October/early November. They started the job on November 1st and finished the 2nd!! Now the crew - WOW. Early to the job. Worked non-stop. Cleaned up after themselves and were EXTREMELY kind and courteous. I was told this would take three days which was already very impressive. Kevin and his crew finished in 1.5 days. Their outstanding professionalism and absolutely stunning craft are impeccable. It’s clear they work really well together and that everyone has a clear and coordinated job to get things done so efficiently without sacrificing the construction or craft. They brought one truck that also had one small bulldozer on a trailer the first day, and then just a work truck the second day. This was actually really helpful as we live on a tight street. We had neighbors who used another company to do their deck and the company they hired was disrespectful, loud, and brought huge trailers that clogged up our street. The Keystone crew was the exact opposite - and got the job done in a quarter of the time!!! Keystone was awesome - professional, timely, and courteous. Best experience I have ever had with a contractor. I highly recommend using them!"
