Sleepy Hollow Neutral-Plane Window & Door Replacement — Insured

Sleepy Hollow sits in Westchester County with a population of roughly 9,986, close enough to Yonkers that crews move between the two constantly. Local landmarks and corridors residents know well include the Sleepy Hollow Cemetery grounds, Kingsland Point Park.

Local knowledge is not a marketing line here. Sleepy Hollow properties share soil, weather, permit rules and construction eras with the rest of Westchester County, and a window contractor who works the area weekly already knows what fails locally and what holds up. That is the difference between a bid and an accurate bid.

Call (833) 996-2244 or send the form and we schedule a site visit in Sleepy Hollow, usually within a couple of days. You get a written, itemized free estimate with materials and scope spelled out — no verbal ballpark, no pressure, and no charge whether you hire us or not. Se habla español.

We also serve Pelham, NY and the rest of the lower Hudson Valley. Everything starts at the Yonkers Window Replacement homepage.

Yonkers Window Replacement covers the same range of work in Sleepy Hollow that we do in Yonkers — nothing is carved out because the address is a few miles up the road:

• Glass Repair & Insulated Glass Units — If the sash and frame are square and sound and only the sealed glass has failed, you almost certainly do not need new windows. The energy code is explicit: glass-only replacement in an existing sash and frame is exempt from the replacement fenestration requirements.
• Commercial Storefront Glass — Commercial glazing follows a different code path and the numbers are not the ones on the residential page. Commercial buildings answer to the commercial provisions of the state energy code, which set their own fenestration limits and add a window-to-wall area calculation.
• Energy-Efficient Windows — The number changed on the last day of 2025. New York's 2025 energy code took effect with no grace period, and for climate zone 4A, which covers all of Westchester, replacement windows now have to reach a 0.27 U-factor and a 0.40 solar heat gain coefficient.
• Vinyl Replacement Windows — Vinyl is the right answer for most of the housing in this city, and we will say so before you ask. On a two- or three-family frame house the arithmetic is not close: it costs a fraction of clad-wood and hits the code numbers easily.
• Fiberglass Windows — Fiberglass answers one problem better than anything else on the market here, and the problem is daylight. Replacing into an existing masonry opening with an insert means the new frame sits inside the old one, and every extra millimeter of frame section is glass you lose permanently.
• Wood & Clad-Wood Windows — Clad-wood exists for one situation, common in the north and west of this city: the interior casing is original and worth keeping, and a white plastic frame beside it would look like exactly what it is. The outside gets a metal or composite skin.
