Keystone did a phenomenal job building my new deck. They took 100% responsibility for every aspect of the job from beginning to end - always keeping me informed. The crew who worked on deck was great - always on time, professional, considerate, hard working, and always cleaned up job site every day. The finished product is better than I imagined - structurally sound and absolutely beautiful! I love it!

- Michele

We could not say enough good things about this company and it's employees from the office workers to the field crew. Excellent work and very professional. We could not find another company to give us what we wanted. We were giving up hope until we found them at a Home Show. They kept us informed along the way as to their timing of each step of the job and ended up getting the work done earlier in the month, since they had an opening. They handled all the permits and all we did was have to pick out our choices of materials. They were all very attentive making it a very easy process. We had our deck boards replaced with Trek and a new aluminum railing system installed with lighting. We also had a Pergola built with a retractable awning. It has worked out so well we now are enjoying sitting out on our deck again and considering it a new room added on to our house. We would totally recommend this company and would use them again. Thank you.
