Aurora IL Window Replacement provides professional egress windows in Aurora, IL for residential and commercial properties across Chicago's far western suburbs. Basements get finished in this city constantly, and this is the one window subject in Aurora where the local inspection actually decides something. The rule is geometric, it is written down, and it is easy to check before you spend anything.
The residential code requires at least one operable emergency escape and rescue opening in every basement and in every sleeping room. Where a basement contains sleeping rooms, each of those rooms needs its own. The opening has to reach a yard or court that gets to a public way. The dimensions are fixed. Net clear opening of at least 5.7 square feet, reduced to 5.0 square feet for a grade-floor or below-grade opening.
Nothing narrower than 20 inches counts, nothing shorter than 24 inches counts, and a sill sitting more than 44 inches above the floor beneath it fails whatever the area works out to. Those figures are measured with the sash in the position normal operation puts it, not with the sash removed. Basements used only to house mechanical equipment under two hundred square feet are the exception.
Below grade, the well comes with the window. A window well needs at least 9 square feet of horizontal area with a projection and width of at least 36 inches, it has to let the window open fully, and past 44 inches of depth the well itself has to carry fixed steps or a fixed ladder. Wells drain to the foundation drainage system unless the soil is a well-drained group I classification.
Now the part that saves people money. The code carries an explicit exemption for replacement windows: a replacement is exempt from the opening dimension requirements and from the well ladder requirement so long as the unit ordered is the largest stock size in that manufacturer's range which will go into the frame or rough opening you already have, and the job is not a change of occupancy.
That exemption exists because the alternative is asking homeowners to cut foundations to replace a worn-out window. Read that carefully, because it is the difference between a window order and a concrete saw. If your basement bedroom already exists and you are simply replacing a tired window in it, you do not have to enlarge that hole.
You have to buy the biggest standard unit that fits and not downgrade the opening. The exemption disappears the moment you are creating a sleeping room that was not there. Framing a new bedroom in an unfinished basement is exactly the case the rule is written for, and that job needs a proper opening, a well and, usually, a cut foundation with a header over it.
Cutting a concrete or block wall means a saw, a header, a well, a drain connection and backfill, and it is priced accordingly. So our first question is never what size window you want. It is whether this room is already a bedroom. If it is, we will often quote a straight replacement for a fraction of what an egress cut costs, and tell you to spend the difference elsewhere.
Our licensed and insured team brings the right materials and equipment to every job — warm-edge stainless spacer inside a dual-seal insulating glass unit, certified whole-window U-factor of 0.28 for climate zone 5A, block-frame insert set into a sound existing jamb and sill, full-frame tear-out carried back to the rough opening and sheathing, low-expansion polyurethane foam gunned around the perimeter shim space, sloped sill pan with end dams lapped over the water-resistive barrier — and backs the work with a written workmanship warranty. We serve Aurora and nearby communities including Naperville, Bolingbrook, Downers Grove, Wheaton.

Materials, equipment and how we do egress windows
The difference between egress windows that lasts and egress 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 inside a dual-seal insulating glass unit, certified whole-window U-factor of 0.28 for climate zone 5A, block-frame insert set into a sound existing jamb and sill, full-frame tear-out carried back to the rough opening and sheathing, 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 Aurora 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 far western suburbs means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Aurora Chooses Aurora IL Window Replacement
- ✓Every opening on our quote carries a named manufacturer, a named glass package and a certified whole-window U-factor, so two bids can be compared on the same basis instead of on adjectives.
- ✓We measure the net clear opening your existing bedroom window delivers before ordering anything, because an insert frame takes inches off a hole and that arithmetic decides whether the room still complies.
- ✓We price the cheaper fix on the same page as the replacement, whether that is a sealed unit, a set of rollers, rescreening or a storm panel over sound original sash, and we say which one we would buy.
- ✓We know which code applies to what. The energy number comes from the state and cannot be moved locally; the opening geometry comes from the residential code and is judged at inspection. Different rules, different arguments.
