“Our new deck is fantastic. Incredible company and crew to work with! Some of the most professional contractors I’ve encountered before. We were so pleased to meet all the people that we worked with. The crew that was here not only was professional, super efficient, and clearly masters of what they do, but also just incredibly kind people. Can’t say enough good things about them!”

Ontario County, located in western New York, has a history dating back to its founding in 1789. Originally part of a much larger region, the county played a key role in the early development of New York State. The area was historically inhabited by the Seneca Nation, one of the Six Nations of the Iroquois Confederacy, before European settlers arrived. Over time, Ontario County became a hub for agriculture, thanks to its fertile soil and proximity to the Finger Lakes. The county also contributed to the growth of transportation networks, including early roads and canals that supported trade and expansion. Today, Ontario County blends historical charm with modern development, preserving landmarks while supporting thriving communities. You can learn more through the official county website and its Wikipedia page.
