Elgin Window Pros provides professional bay & bow windows in Elgin, IL for residential and commercial properties across the Fox River valley in Kane County. A bay or a bow is not a window order. It is a small piece of construction that happens to contain glass, and the permit counter here reflects that the moment the opening changes width.
Priced as a window it always comes in too cheap, and the difference shows up later. The city asks for a floor plan whenever window sizes change, showing the existing sizes, the new sizes and the dimensions of the room. Go wider than what is already there and that plan also has to carry the new header size and the additional framing. That is a drawing and a review, not a quick permit.
Budget for the drawing and the extra review time when you plan the job. The structure above the opening is why. A wider span carries more load into fewer points, and in a pre-war house the studs overhead are often one continuous balloon-framed run rather than a platform wall with a tidy header pocket. Cutting into that without a drawing is how a floor above starts to sag.
A structural check before demolition costs a fraction of what jacking a floor back into place does afterward. Then there is the projection itself. A bay hangs off the wall and needs a head board, a seat board, knee braces or cable support tied to the framing, insulation packed into the seat and the head, and its own small roof flashed back into the wall above it.
None of that appears on a window order form, which is exactly the problem with treating it as one. That roof is where bays fail in this climate. Snow sits on a low-pitched bay roof for weeks, meltwater backs up beneath the shingles, and the first evidence is a stain on the ceiling of the bay seat. We build it with a self-adhering membrane and a real counterflashing rather than a bead of sealant at the wall.
Ice damming at the wall junction is the specific failure, and it is entirely preventable with the right membrane. Because of all that, our first suggestion is usually a bow or bay set into the opening you already have. A three-unit assembly inside the existing width buys most of the view and most of the light without a header calculation, a plan submittal or a review.
It is also considerably quicker, since nothing structural is being altered and the exterior stays intact. If a room genuinely needs the projection, such as a small dining room where a seat adds usable floor, or a front room with nowhere else to sit, we will build it and we will price the framing and the roof as separate visible lines rather than folding them into a per-window figure.
That way you can see what you are actually paying for and decide whether the projection is worth it. What we will not do is quote a bay as though it were four windows in a row. Anyone doing that has not looked carefully at what happens above the opening. Ask any bidder what they intend to do above the header and how the bay roof ties into the wall, and listen carefully to the answer.
Our licensed and insured team brings the right materials and equipment to every job — pan flashing carried a full six inches up both jamb legs, hand-packed mineral wool filling an emptied sash-weight pocket, brickmould and exterior casing left undisturbed on a pocket install, an NFRC label left adhered to the glass and faced outward for final, backer rod bedded behind a tooled sealant joint at the exterior reveal, compression-seal casement hardware bearing on a continuous jamb gasket — and backs the work with a written workmanship warranty. We serve Elgin and nearby communities including South Elgin, St. Charles, Geneva, Batavia.

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 pan flashing carried a full six inches up both jamb legs, hand-packed mineral wool filling an emptied sash-weight pocket, brickmould and exterior casing left undisturbed on a pocket install, an NFRC label left adhered to the glass and faced outward for final, 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 Elgin 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 Fox River valley in Kane County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Elgin Chooses Elgin Window Pros
- ✓Every opening on our quote is marked insert or full replacement before you sign, because that one word decides the flashing, the permit route and roughly a third of the price.
- ✓Where a full replacement is going in, the pan flashing is a priced line item you can point at, not a detail buried behind trim that nobody ever checks.
- ✓We pull the permit and book the final ourselves, and we leave every label stuck to the glass and turned outward so the inspector can read it from the sidewalk.
- ✓We ask what year the house was built before we price a single window, because a boxed weight pocket and a modern jamb liner are two entirely different jobs.
