Yonkers Window Replacement provides professional patio & sliding glass doors in Yonkers, NY for residential and commercial properties across the lower Hudson Valley. The energy code tells you something useful about patio doors if you read two lines together. Sliding doors are held to the same 0.3 cubic feet per minute air-leakage limit as windows. Swinging doors get 0.5. The code is admitting that a hinged door leaks more.
That is worth knowing here because of where these doors end up. On a hillside house the rear elevation is the one standing above the fall, the deck is often a platform on posts rather than a patio on the ground, and the door onto it is the lowest opening on the most weather-exposed wall of the building.
Which puts it in the worst place for two separate reasons. It sits low, so in winter it is below the level where the building's pressure reverses and it is being pulled inward on hard, drawing cold air across the threshold every time the wind picks up. And it faces the open drop, so wind-driven rain arrives at the sill rather than falling past it.
So the sill is the whole job. A sliding door sill is a horizontal track that collects water by design and gets rid of it through weeps, and if those weeps are undersized, badly positioned or blocked, the track fills and the water finds the floor structure underneath. On a deck door over a drop, that structure is the part of the house you least want wet.
Every patio door we fit gets a sloped sill pan with an end dam turned up at both sides, lapped so anything getting past the track is carried out over the face of the wall rather than into it. That is not an upgrade, it is how the door should be installed. If a quotation lists a sill pan as an extra, ask what the alternative is.
Rollers and track are the maintenance story. A patio door that has become heavy is almost always running on worn rollers or a track full of grit, and the number of perfectly sound doors replaced over what is a modest repair is genuinely large. If the frame is square, the glass is intact and the lock still engages, ask about rollers before you ask about a new door.
Glass in a patio door is tempered as a matter of code, because it is a large pane at floor level that people walk into. Where the door is on a ground floor or reachable from a deck stair, we will usually put laminated in the fixed panel instead, for the same forced-entry reason that applies to ground-floor windows.
The multi-panel and lift-and-slide products are excellent and they are heavy. On a deck cantilevered off a hillside wall, the header and the deck framing both need checking before you specify one, because these doors weigh several times what the unit they replace weighed.
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 patio & sliding glass doors
The difference between patio & sliding glass doors that lasts and patio & sliding glass doors 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.
