The Finger Lakes Region in New York is a beautiful place and home to the 11 lakes from which the region gets its name. These lakes are long and narrow and were formed from over-deepened glacial valleys. The lakes range significantly in size although none exceeded 3.5 miles in width. This area was once home to the Iroquois, a Native American confederacy of numerous tribes. They remained in control of the region until 1779, Sullivan Expedition. This region was the starting place for the 19th-century Christian revival, the Second Great Awakening, and important in the Underground Railroad.

Brian & Kaitlin Stone: "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. Despite the quick turnaround, the work was meticulously done.
The yard was left clean and in good shape after both days of work. All employees were respectful and hard-working.
Mahlon was very attentive to his emails and responses were very quick. He really stands by his high-quality work; when there was a small issue with the gate, he immediately sent someone to our house to replace the flawed part, no questions asked. We enjoyed the nice touch at the end too with the box. The finished product is outstanding! Thank you to everyone at Keystone Custom Decks!"
