Four Decades of Custom Decks, Patios, and Outdoor Kitchens Across Upstate New York
Keuka Park, United States - September 23, 2026 / Keystone Custom Decks NY /
Keystone Custom Decks NY has operated for more than four decades in the custom outdoor living space industry, offering a full range of design and construction services to homeowners throughout the Finger Lakes region and Central and Upstate New York. Since opening its Keuka Park location, the family builder has delivered custom decks, patios, outdoor kitchens, and more while expanding its service model to include complimentary 3D renderings, full permitting management, and a lifetime workmanship warranty.
A Family Business Built on Decades of Regional Work
Keystone Custom Decks was founded in East Earl, Pennsylvania, in 1983, and has spent more than 40 years serving homeowners statewide. Roughly a decade ago, founder Amos Esh's nephew, Mahlon Esh, extended the family business into New York's Finger Lakes region, and in 2022 the company completed a dedicated showroom in Keuka Park that now anchors its client consultations there.
Rather than pursuing national scale, Keystone Custom Decks NY has kept a regional focus in each market it serves, building familiarity with local conditions in each -from Pennsylvania's permitting requirements to the climate and terrain specific to Upstate New York. That regional focus has shaped how the company approaches project scoping, material selection, and construction timelines in every market it operates.
Service Offerings Span Design Through Permitting
Keystone Custom Decks NY builds custom decks, patios, and outdoor kitchens, along with pergola structures and more, covering the full range of outdoor living installations residential clients typically request. The company also handles permitting on behalf of homeowners, managing the administrative process with local municipalities so projects can move forward without delays from incomplete applications or unfamiliarity with local codes.
As part of its design process, the company provides complimentary 3D renderings that allow clients to visualize a proposed structure before construction begins. This step gives homeowners the opportunity to review dimensions, materials, and layout details and request revisions without incurring additional cost.
Warranty Coverage and the Showroom Experience
The Keuka Park showroom allows prospective clients to see materials and finishes in person before committing to a project. This physical space has remained a consistent part of the company's business model since 1983, functioning as the starting point for consultations that lead into the 3D design and permitting phases.
The company backs its construction work with a lifetime workmanship warranty that covers installation quality rather than the materials themselves. That distinction means the warranty is tied to how a project is built - the structural connections, the framing, and the assembly process - rather than to manufacturer specifications on decking boards or composite materials, which carry their own separate coverage terms.
