Rochester is now the third-largest city in the state of New York with a population of over 200,000 people. However, it started small in 1817 when three men purchased land along the Genesee river and planned a new settlement. It quickly became an important hub with industries such as milling, brewing, and textiles playing a key economic role. The city was also important in political and social reform with influential figures just as Fredrick Douglas, and Susan B. Stanton hailing from the area. Today the city is known, among other things, for its history and high quality of life.

Tiff O:  "I have nothing but positive things to say about Keystone Custom Decks! Mahlon was amazing to work with and so helpful with helping us with the design. Our deck was built in early March (5 months ago) and we have yet to find anything we would have liked to be done differently. It is perfect! The crew was professional, on time, clean and quick! Other than the sounds of work being done, I wouldn't have even known they were there. It was such a wonderful experience from start to finish! I have recommended them to anyone that mentions needing a deck or a patio. I will definitely be calling them again for our next project! THANK YOU Keystone Custom Decks!"

Lara R:  "Our experience with Keystone Custom decks was beyond our expectations and we can hardly express how pleased we are with our new deck and front porch railing, and with the service we received! Every single person from the small team (led by Anthony - who was so great) who worked on our deck was kind, courteous, professional, personable, clearly knowledgable, skilled, and talented in their work, paid attention to the details, did quality, solid, and consistent work, and made sure everything looked great and was done well and correctly. They took great care of our yard and the neighbors' yards adjacent to ours and left it looking just as they had when they arrived. The ease and relief of working with a company and individuals that we felt to be in really good hands with, and the end result of a deck that is exactly what we designed and hoped it would be, has been worth every penny."

Holly H: "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."

Dave Garrison - "Keystone is a top tier deck builder. They helped design and bring to life the vision my wife and I had for our new deck with three season room. They handled everything which freed us from having to hire engineers and architects. The team was prompt and cleaned up the work area each day and neatly put things away without leaving messes. The crew even moves building materials stacked on the lawn throughout the project to help prevent damage to the property. Their customer service is top notch. Real professionals. Can't say enough good things about Keystone."
