A. M., Ossining
Sample
“They did the kitchen carpentry in our Ossining house. Showed up, looked at the room, gave a number, and built what they quoted.”
Sample layout

Custom deck design, construction, and repair for outdoor living that lasts Westchester weather.
Part of Construction
New decks, repairs, and rebuilds. Wood or composite, framed to code from Ossining. We look at the ledger, the footings, and the span — not just the boards on top.
Layout and structure
Footings, framing, and ledger tied into the house the right way.
Decking and rails
Boards, stairs, and rails to the plan we quoted.
Cleanup
Cut-offs hauled. You can walk it when we leave.
Wood
Pressure-treated and cedar
Lower upfront cost. Needs stain and sealing on a schedule.
Composite
Trex and PVC
Less yearly upkeep. Higher material cost. We walk that on site.
