Bartlett Window Replacement provides professional custom window installation in Bartlett, IL for residential and commercial properties across Chicago's northwest suburbs along Route 59. More than a third of Bartlett's housing units went up between 1990 and 1999, against roughly six percent of Cook County's. That decade liked a half-round transom over the front door, and those are the shapes we template most often here.
The radius is what people get wrong. Factory half-rounds come in set radii. The one above your door was built to the brickmould a carpenter actually nailed on, and thirty winters have moved it since. We read the span, the rise and the spring line off the opening, never off the original invoice.
On a true curve or an ellipse that is not enough on its own, so we cut a physical template to the finished opening and send it with the order. Nothing curved should ever be ordered from a tape measurement alone, and any fabricator who accepts one is planning to blame your wall.
Gable trapezoids work the same way with a different instrument. The rake angle comes off the roof pitch, taken on site with a bevel, and it gets written onto the order sheet so a second round years later still lines up with the first.
True divided light deserves a straight answer. Real muntins mean a separate sealed unit behind every light, so the price scales with the count rather than with the window. A grille set between the panes costs a fraction and reads correctly from the street on most elevations. We will say which your front looks like.
Then the money, which is the honest spine of this page. A custom unit is manufactured for one opening and cannot be resold, so your deposit is gone the moment the order releases. Ask for the fabrication lead time in writing, and plan how the opening will be weathered if a crate arrives damaged and goes back.
The permit here is a village matter and unusually specific. Windows and doors sit in Bartlett's express permit category, filed through the Viewpoint portal by a contractor holding a village license, a ten-thousand-dollar permit bond and a liability certificate naming the Village. The bond is what the Village falls back on when a job is abandoned mid-order. A shape that changes the opening leaves the express route and goes in with drawings instead.
Because a permit is always in play, so is the state energy code, which Illinois applies to residential work a municipality requires one for. The edition behind a permit filed today is the 2024 one, adopted statewide at the end of November 2025. So ask whether the certified label will belong to your actual unit or to the rectangular series behind it, and settle that before the order releases rather than at the final.
Our recommendation. If the opening is a rectangle in an odd size, buy a standard unit and absorb the difference in an extension jamb and trim. If a 1990s half-round still has a sound frame and sound hardware and only the glass has failed, that is a sealed-unit order, not a custom window order, and it costs a small fraction of one.
Our insured team brings the right materials and equipment to every job — snap-in interior glazing bead bedded on butyl glazing tape, polyisobutylene primary seal behind a silicone secondary seal, desiccant-filled aluminum box spacer of the 1990s glass package, sash lite bonded to its frame with structural glazing silicone, coil-spring block-and-tackle balance matched to sash weight, tilt latch and pivot bar cut for a discontinued sash profile — and backs the work with a written workmanship warranty. We serve Bartlett and nearby communities including Streamwood, Hanover Park, Schaumburg, Hoffman Estates.

Materials, equipment and how we do custom window installation
The difference between custom window installation that lasts and custom window installation that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with snap-in interior glazing bead bedded on butyl glazing tape, polyisobutylene primary seal behind a silicone secondary seal, desiccant-filled aluminum box spacer of the 1990s glass package, sash lite bonded to its frame with structural glazing silicone, 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 Bartlett 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 Chicago's northwest suburbs along Route 59 means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Bartlett Chooses Bartlett Window Replacement
- ✓Every quote carries the reglaze price beside the replacement price for the same opening, because on most 1990s Bartlett sash the failed part is the glass and the frame is still square.
- ✓We take a sash apart before we bid. Whether a glazing bead snaps out or the lite is bonded into the vinyl decides the entire job, and it is a two-minute answer nobody else bothers to get.
- ✓When a balance, a roller or a crank operator is the only thing wrong, we quote that alone and hand it back. It does not get folded into a whole-house number you did not ask anyone for.
- ✓High great-room and transom glass is priced with its staging on the same line, so the reach is visible as its own cost and you can decide how much of that elevation to finish in one visit.
