Building decks in Valhalla
Valhalla is a hamlet in the Town of Mount Pleasant at the foot of the Kensico Dam, finished in 1917. Kensico Dam Plaza, the county park below the dam, is a local landmark.
Homes here range across many decades, and older decks are common. If yours was built long ago, have the ledger and posts checked before adding new boards. Lots near the reservoir and the Bronx River Parkway can be hilly, which affects deck height and stairs.

When you send a request from Valhalla, we pass it to a local deck builder who works in your area. The builder reaches out, looks at the slope, soil and access, and writes up their own estimate. You decide whether to hire them, and the request costs nothing.
Projects range from a new deck or a low-maintenance composite deck to deck repair, a full replacement, new railings and stairs or a screened porch. Footings in Westchester go below the frost line, which Trusted Local Contractors puts at 42 inches.
Most Westchester municipalities require a building permit for a new deck, and your builder should pull it. Before you hire anyone in Valhalla, confirm their Westchester County home improvement license and insurance, and get the size, materials, railing, stairs and price in writing. A photo of the back of the house sent with your request helps the builder come prepared.
