Stamford Window Replacement provides professional double-hung windows in Stamford, CT for residential and commercial properties across southwestern Fairfield County. The double-hung is the default window of this city's older stock, and Stamford's version of it is tall. A 1920s opening carrying a sash close to three feet wide and over three feet high is common, and that sash is heavy long before anyone chooses a glass package.
Weight is the whole story on this page. The original design solved it with cast-iron weights hanging in pockets beside the frame, connected by cord over a pulley. It works beautifully and it costs you the pocket, which is an uninsulated cavity in the wall next to every window in the house.
Modern replacements move that job into a balance in the jamb. There are three families worth knowing. Spiral balances are cheap and adjustable and struggle with heavy sash. Block-and-tackle balances handle real weight and are what a tall unit should have. Constant-force coil balances are compact, smooth and generally the best of the three, and they are rated by weight range like the others.
The failure we get called about most is a new window that will not stay up, or that slams. Nine times out of ten the balance class was ordered from a size chart while the glass was upgraded to triple glazing afterwards, and nobody recalculated. Adding a third lite to a large sash can add twenty pounds or more, which is enough to move it out of the range the balance was picked for.
So we weigh the proposed sash rather than guessing. Glass runs roughly one and a half pounds per square foot for every eighth-inch of thickness, and the arithmetic takes a minute at the kitchen table. The balance class then goes on the order, in writing, next to the glass package it was chosen for.
Two other things belong on a Stamford double-hung. Sill height, because tall openings in this stock often start low, and second-floor sash over a walk or a drive fall under the fall-protection rule; opening control devices to the F2090 standard cost very little and are far better bought with the window than retrofitted. And a full-frame versus insert decision, since an insert into an old jamb gives up several inches of glass in each direction.
For rooms where sash weight is genuinely awkward, we will suggest a different configuration entirely: a fixed upper lite with an operable lower sash, or a casement in the openings that need to open widely. Not every tall opening has to be a double-hung just because the original was, and elderly owners in particular are better served by a crank than by forty pounds of sash.
Repair is on the table too. Balances, sash locks, weatherstrip and tilt latches are all replaceable on most lines, and a well-made unit that is twelve years old and out of adjustment is not a candidate for replacement. We will fix that and leave the rest of the house alone.
Our licensed and insured team brings the right materials and equipment to every job — heat-strengthened lites in oversized fixed units, structural mullions between stacked glass panels, block-and-tackle balances sized to sash weight, poured-and-debridged thermal breaks in aluminum extrusions, pultruded fiberglass sections at narrow sightlines, pan-flashed sills with end dams and weep paths — and backs the work with a written workmanship warranty. We serve Stamford and nearby communities including Greenwich, Darien, New Canaan, Norwalk.

Materials, equipment and how we do double-hung windows
The difference between double-hung windows that lasts and double-hung windows that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with heat-strengthened lites in oversized fixed units, structural mullions between stacked glass panels, block-and-tackle balances sized to sash weight, poured-and-debridged thermal breaks in aluminum extrusions, 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 Stamford 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 southwestern Fairfield County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Stamford Chooses Stamford Window Replacement
- ✓Size drives our specification, not brand. Glass area, unit weight and span go on the schedule next to every line, because those three numbers decide the frame material, the balance class and the glass.
- ✓Wide fixed lites get heat-strengthened glass where a shading pattern or a tight interior blind will stress the pane. Owners are routinely sold whole new windows for what is a thermal stress crack.
- ✓We tell customers in writing that Stamford is not a windborne debris region under the state's own town-by-town table, so nobody buys missile-rated glazing here believing the code demands it.
- ✓Bedroom replacements are quoted against the state's replacement exemption and Connecticut's removable-sash allowance, so an opening rarely has to be cut larger and a header rarely has to be added.
