Yonkers Window Replacement provides professional bay & bow windows in Yonkers, NY for residential and commercial properties across the lower Hudson Valley. A bay projects out of the wall, so it stops being a window and becomes a small room with five surfaces exposed to weather. On a hillside elevation where the ground drops away beneath it, that changes the job from glazing into a piece of building.
The heat does not usually leave through the glass. It leaves through the floor of the bay and the soffit underneath it, which are the two parts nobody photographs and the two parts most often built as an afterthought. A bay with an uninsulated floor is a cold platform sitting in the wind, and the window seat above it will be the coldest spot in the room regardless of what glass you specified.
So our quotes for bay and bow work always separate the glazing from the enclosure. Floor insulation, a properly detailed soffit, an air barrier that actually joins to the main wall, and a head flashing over the roof of the bay that is lapped into the wall above rather than sealed to its face. If a quotation you are comparing does not name those, it is pricing a different job.
Support is the second question and on these lots it is not academic. A cantilevered bay is carried either on extended floor joists or on knee brackets, and on a wall standing above a steep fall the load path has to be genuinely worked out rather than assumed. We open up and look before quoting, because discovering the answer during the fit is how a one-day job becomes a three-day one.
The roof of a bay is the part that fails. It is small, it is nearly flat on many of the older ones, and it sits under a wall that sheds water straight onto it. Where we are rebuilding a bay we will normally increase the pitch if the head height allows, and where it does not we detail it as a genuinely low-slope roof rather than as a shingled afterthought.
The case for a bay is real and worth stating. It brings light in from three directions rather than one, which in a deep pre-war room is transformative, and on the west-facing streets it buys a view of the river that a flat window in the same wall does not.
The case against is that a bay is the single most expensive way to buy a square foot of glass, and on a rear elevation over a drop it is also the most exposed thing on the building. Where an owner wants one purely for the room's sake and the wall faces the weather, we will often suggest a large fixed lite flanked by two operating units instead. Same light, a fraction of the cost, nothing cantilevered.
Bow windows differ only in geometry: four or five equal units in a shallow curve rather than three at sharp angles. Everything said above about floors, soffits and roofs applies identically, and the curve makes the roof detail harder rather than easier.
Our licensed and insured team brings the right materials and equipment to every job — warm-edge stainless spacer, compression bulb weatherstrip at the sash perimeter, sloped sill pan with an end dam, low-expansion foam at the perimeter shim space, polyamide thermal break in an aluminum section, argon-filled sealed glazing unit — and backs the work with a written workmanship warranty. We serve Yonkers and nearby communities including Mount Vernon, New Rochelle, White Plains, Scarsdale.

Materials, equipment and how we do bay & bow windows
The difference between bay & bow windows that lasts and bay & bow windows that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with warm-edge stainless spacer, compression bulb weatherstrip at the sash perimeter, sloped sill pan with an end dam, low-expansion foam at the perimeter shim space, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Yonkers job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in the lower Hudson Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Yonkers Chooses Yonkers Window Replacement
- ✓We price a tall building by elevation and floor, not by a unit count. The sixth floor and the first floor of the same walk-up get different air-leakage ratings because they fail in opposite directions.
- ✓We read the sash before we quote a replacement. Where the frame and jamb are sound, re-glazing an existing sash is exempt from the energy code's replacement rules and costs a fraction of a new unit.
- ✓Nobody here needs impact-rated glazing. Yonkers sits outside any wind-borne debris region. Saying that out loud costs us work every year, and we say it anyway.
- ✓Hillside lots get surveyed for grade before we talk about basement openings. Which wall a cellar window goes in matters far more here than the numbers that go on the order form.
