Yonkers Window Replacement provides professional fiberglass windows in Yonkers, NY for residential and commercial properties across the lower Hudson Valley. 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.
That loss is not trivial in this stock. A 1920s apartment window was sized to light a room forty feet deep with nothing but daylight, and the rooms are still forty feet deep. Take three inches of visible glass off each side with a fat insert frame across a whole facade and the apartments genuinely get darker, which is the sort of thing nobody notices on a drawing and everybody notices in February.
Pultruded fiberglass carries far more load per unit of section than vinyl does, so the frame can be slimmer for the same opening and the same wind pressure. On a tall pre-war sash that difference shows up directly as retained glass area, and on a matched facade it means the replacement reads as a window rather than as a replacement.
The second thing fiberglass does is take paint properly. That matters on the estate blocks above the parkway and on any street where the elevations were designed as a set, because it lets a new unit be finished to match originals instead of being available in whatever four colors the vinyl catalogue runs. Dark finishes also behave far better in fiberglass than in vinyl on a sun-facing wall.
Structurally it is the frame we reach for on exposed hillside elevations. A house standing on the shoulder of one of the hills above the river catches wind that the sheltered street below never sees, and a stiffer frame deflects less, which keeps the weatherstrip in contact and the sash operating instead of binding.
The honest counterargument is cost. Fiberglass sits well above vinyl and often close to clad-wood, and on a rear elevation, a rental unit or an opening nobody sees, it is money spent on a benefit nobody will experience. We do not specify it everywhere, and a quote that puts fiberglass in a cellar light court is a quote written by somebody selling rather than measuring.
Where it genuinely pays is the visible front elevation of a building you intend to keep, particularly where the openings are tall, the sightlines are narrow and the wall is masonry. That describes a great many buildings in this city, which is why fiberglass features more here than the national mix would suggest.
We will usually price it against clad-wood rather than against vinyl, because that is the real decision. Clad-wood gives you a wood interior; fiberglass gives you a frame you can paint on both faces and a slimmer section outside. Which one wins depends on whether the inside casing is original and worth answering to.
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 fiberglass windows
The difference between fiberglass windows that lasts and fiberglass 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.
