Sleepy Hollow Neutral-Plane Window & Door Replacement — Licensed & 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.

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:

• 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.
• Aluminum Window Frames — We will talk most homeowners out of aluminum, and it is worth explaining why rather than refusing. Aluminum moves heat about a thousand times faster than vinyl does.
• Double-Hung Windows — Double-hung is the default here, and for good reason. Almost every pre-war building in this city was glazed with it, the proportions assume it, and on a street of matched facades a casement among the double-hungs is a mistake you cannot undo cheaply.
