Window repair in Elmhurst often starts with a foggy sash on a 1920s brick home, and a new glass unit is usually enough. Apex Window Werks makes those units in its own shop and can often replace a window within 48 hours. The work carries a 5-year workmanship warranty.

Our Elmhurst Window Repair & Replacement Services
Between wind-driven spring rain and January cold, Elmhurst windows tend to fail in a handful of repeatable ways. Here is how we deal with each one.
Bring us the window that sticks, leaks, or will not lock. Our technician diagnoses the actual fault, rebuilds or replaces only that part, and runs the window through a full open-and-close cycle before leaving. Wood, vinyl, and aluminum frames are all in scope.
Sometimes the numbers favor a new unit: a frame rotted through, or repair costs closing in on the price of new. We manufacture our own insulated glass units, which is why we can often install a replacement window within 48 hours. Custom sizes and specialty glass add time, and you get the date before work begins.
Original wood windows are a big part of what makes Elmhurst's 1920s through 1950s houses appealing, particularly around Wilder Park. Stripping, repairing, and refinishing one often costs less than a custom reproduction, and the sash keeps the proportions the house was built with.
Peeling paint along the bottom of a window often points to moisture hiding behind it. We cut back to solid wood, rebuild with treated material, and seal the joint where the frame meets brick or siding.
Because we manufacture insulated glass units ourselves, fogged windows are among our quickest fixes: we take your measurements, make a matching unit, and fit it into the existing sash. The haze comes from a broken edge seal that no cleaning can reach, and the swap runs well below the price of a new window.
A hairline split in exterior caulk is easy to miss and expensive to ignore, since rain follows it behind the trim. We remove the failed bead, prep the joint, and apply a flexible sealant rated to move with seasonal expansion.
In old wood sashes, a thin bead of compound is all that holds the glass in. Once it cracks or drops out, the pane rattles and weather gets in, so we cut away what is left, re-bed the glass, apply new compound, and prime and paint it to finish.
A sash that needs a prop to stay open, or drops shut without warning, has a broken balance. We identify which type is in your window (spring, coil, or channel), source a match for the sash weight, and install it so the sash holds at any height.
A window that will not lock invites both intruders and drafts. We replace cranks, handles, locks, hinges, and operators with parts matched to the manufacturer, and child-safety locks are available for bedrooms and nurseries.

Window Types We
Service in Elmhurst
Infill construction has put brand-new windows beside ninety-year-old ones on many Elmhurst streets, so we work on nearly every style in use.
Most older brick homes in Elmhurst rely on double-hung windows. When one will not stay up, sticks in its track, or leaks at the meeting rail, we rebuild the balances, ease the sashes, renew the weatherstripping, and bring back tilt-in cleaning where the window was built with it.
Casements crank outward and press shut against a gasket. If the handle spins freely or the sash sits crooked, the operator or arm is worn, and we replace it and fit fresh seals so the sash pulls tight.
Awning windows hinge at the top and crank out at the bottom, which keeps rain out but wears the arms. We swap tired arms, replace the gasket, and re-hang the sash square.
A bay window leans out from the wall on its own support, so sagging, gaps at the seat board, and leaking corner joints are the usual complaints. We re-support the seat, reseal the seams, and repair glass and trim while keeping the original angles.
Sliding Windows
Sliders fail at the bottom, where dirty tracks and worn rollers collect. We clean and true the track, fit new rollers, and adjust the latch so the sash moves with one hand.
Double-pane units insulate until the seal fails and fog appears. We replace just the glass unit, made in our own shop, and leave the frame and trim in place.
Common Window Problems
We Solve in Elmhurst
Homeowners usually spot a problem through a symptom: a cold spot near the glass, a sash that will not budge, a damp sill. Match yours below.
- Cracked or shattered panes: Anything from hail to a stray baseball can break a pane, and a hard overnight temperature drop can crack one that was already stressed.
- Foggy glass (failed IGU seal): Moisture sealed inside the unit tells you the edge seal has broken and the insulating gap now holds humid air.
- Sticking or stuck sashes: Paint buildup, swollen wood, a clogged track, or a broken balance can each freeze a sash in place.
- Rotting sills, sashes, and frames: Soft, flaking wood at the bottom of a window means moisture has been getting in.
- Drafts from worn weatherstrip or caulk: Air leaks wherever seals have flattened or caulk has split, and you feel it as cold spots and higher heating bills.
- Broken hardware (cranks, locks, hinges, rollers): Handles spin freely, locks miss the keeper, and rollers grind, all signs that a part needs replacing.
Window Materials We
Work with in Elmhurst
Frame material changes the repair plan, and one crew covers all three.
Wood windows need intact paint and caulk to shed water. We preserve sound wood, rebuild damaged sections, and refinish the surface to restore that protection.
Aluminum frames resist rot but conduct cold, and corners and tracks can corrode. We repair those areas, replace worn parts, and fit better-insulating glass where it helps.
Vinyl never rots, so trouble tends to be a split weld, a bowed sash, or a failed glass unit. We repair what can be repaired and replace the whole unit once the frame is past repair.
Glass Replacement Services
in Elmhurst, IL
Replacement glass has to fit the frame, suit the room, and meet code. Our glass replacement work covers homes and storefronts across Elmhurst.
A broken pane needs fast action. We clear the glass, measure, and install a cut-to-size replacement without disturbing the frame. Calls get a response inside 24 hours, then a crew arrives the following day during working hours (7 a.m. to 6 p.m.). When the pane must be ordered, we board or patch the opening until it comes in.
We manufacture insulated glass units in our own shop, so sizing, spacer color, and sealing are under our control. That is the reason many fogged units can be replaced within 48 hours. Finish choices include bronze, aluminum, grey, and black.
Custom-Shaped Glass Replacement
Odd-shaped openings, whether a half-round transom, a gable triangle, or a circular accent, get a paper pattern and a precise cut, so the new pane seats without gaps.
Tempered & Laminated Glass Replacement
Building code calls for safety glass in certain spots, such as beside doors, near stairs, around tubs, and close to the floor. We source tempered or laminated glass for each of these spots, and tempered orders may need roughly seven days, which we confirm up front.
A broken storefront hurts business right away. For shops along York Street and York Road, we plan the work for slow hours and replace the glass promptly.
Patio door panels take more abuse than any other glass in the house. We replace a cracked or fogged panel and, if the door drags, tune up the rollers and track while we are there.
One Bad Pane or Several?
Book a visit, and our technician measures the opening, prices the work, and tells you whether new glass alone is enough.
Types of Glass We Replace
in Elmhurst
Different openings call for different glass. This is what we make and install.
- Insulated glass: Two or more panes bonded to a sealed spacer, which we manufacture ourselves.
- Double-pane glass: The standard in most newer Elmhurst windows, swapped out unit by unit.
- Single-pane glass: Seen in older wood windows, often with a storm window added.
- Low-E glass: Carries a low-emissivity coating that limits heat transfer in both directions.
- Tempered glass: Heat-strengthened so a break produces small, dull pieces rather than long shards.
- Annealed glass: Standard glass without added strength treatment, suited to openings with no safety requirement.
- Custom-shaped glass: Cut to fit round, arched, or angled frames.
Glass Issues
We Fix
in Elmhurst, IL
Not every glass problem is cosmetic. Below is what we repair and what typically causes it.
- Scratches: Marks from abrasive cleaners, grit on a cloth, or debris in a window well.
- Cracked or shattered panes: Impact, storm damage, or thermal stress that splits the glass.
- Fogging: Lasting cloudiness between the panes, caused by a broken edge seal.
- Condensation between panes: Droplets forming inside the unit, which means moisture is entering through the seal.
- UV and sun fading: Strong sun coming through clear glass lightens floors, rugs, and upholstery.
- Chips and stress cracks: Edge damage that grows each time temperatures swing.
- Mold and staining: Dark spots inside a leaking unit, addressed by moldy window pane repair.

FAQs About Window Repair
in Elmhurst
Can I keep my frame and replace only the glass in my Elmhurst house?
Yes, when the frame is sound, because we make a new insulated unit to fit it. A rotted or warped frame is the cue to replace the whole window.
What makes windows fog up in Elmhurst?
Repeated freeze-thaw cycles in DuPage County strain the edge seal until humid air leaks into the gap between panes. A new sealed unit set into your existing sash fixes it.
Are the original wood windows in older Elmhurst homes worth repairing?
Usually, since we can replace rotted sections, tighten joints, and refinish the wood. Replacement is the better route only when the frame itself cannot be saved.
How quickly can Apex replace a window in Elmhurst?
Many windows are replaced within 48 hours because we manufacture our own glass units. Custom sizes and tempered glass take longer, and the estimate comes with a firm date.
Will fixing leaky windows cut my Elmhurst heating bill?
It can: the U.S. Department of Energy attributes 25 to 30 percent of home heating and cooling energy use to windows. Sealing leaks or replacing failed units recovers part of that.
Do you repair basement windows in Elmhurst homes near Salt Creek?
Yes, we repair or replace basement and egress windows, apply new seals, and confirm the window well drains away from the glass.
