Our Bay Window
Repair Services
We offer full-service bay window restoration tailored to the specific material and construction of your window — whether wood, vinyl, aluminum, or composite.
We replace foggy or failed insulated glass units (IGUs) while keeping the original bay window frame intact. This improves visibility, energy efficiency, and aesthetics — without the cost of a full window replacement.
Our window specialists repair or rebuild rotted, cracked, or damaged wood components, including sills, trim, and structural supports. We use high-quality materials that match your window’s original look and finish.
We fix or replace malfunctioning hardware such as cranks, hinges, handles, and locks. Whether your windows are stuck or difficult to open, our team restores smooth and secure operation.
Leak Sealing and Weatherproofing
To prevent water infiltration and drafts, we reseal joints, replace worn weatherstripping, and apply professional-grade caulking. This stops energy loss and protects your interior from moisture damage.
Frame Realignment and Reinforcement
Sagging bay windows are not only unsightly but can also compromise stability. We realign and reinforce the window structure to restore integrity and prevent future movement or separation.

Common Bay Window Problems We Fix
Bay windows face unique challenges due to their projecting design and multiple glass panels. Our specialists are trained to address all bay window issues:
Condensation between panes indicates seal failure. We replace individual insulated units to eliminate fog and restore clarity — without disturbing the rest of the window system.
Structural Sagging or Separation
Over time, bay windows can shift, causing sagging headers or pulling away from the home. We assess the cause, reinforce support, and realign the unit for proper balance and safety.
Water Leaks and Moisture Damage
Poor sealing around bay window roofs or joints can lead to costly water damage. Our technicians identify all leak sources and apply lasting waterproofing solutions.
Stuck or Hard-to-Operate Windows
If your bay window sections won’t open or close, the issue may stem from warped frames, faulty operators, or misaligned sashes. We repair these mechanisms to restore full function.
Exposure to moisture often leads to wood decay, especially in older bay windows. We replace or rebuild damaged components while preserving the window’s architectural character.
Drafts and Energy Loss
Air leaks and poor insulation lead to higher utility bills and discomfort. We improve thermal performance by sealing all gaps and reinforcing insulation to prevent heat transfer.
We clean and repair windows affected by mold, addressing both the visible growth and underlying damage. Our technicians remove mold, restore frames and seals, and improve ventilation to prevent future buildup while keeping your windows functional and safe.
Don’t Let a Small Window Issue Become
a Big, Expensive Problem!
a Big, Expensive Problem!
Even minor fogging, wood rot, or drafts in your bay window can lead to serious structural damage and high energy bills if left untreated.
Apex Window Werks offers fast, honest assessments and expert repairs — often without replacing the entire window.

Types of Bay & Bow Windows We Repair
Our repair technicians work with all styles of bay and bow windows commonly found across Chicago homes, including:
Traditional 3-Panel Bay Windows
This classic bay window design features a central fixed pane flanked by two angled side windows. Often found in older and modern homes alike, they add space and light to living rooms, dining areas, and front-facing facades.
Bow Windows with Four or More Sections
Bow windows curve gracefully outward with four or more panels, offering panoramic views and a softer architectural appearance. Due to their complexity, bow windows can develop alignment or seal issues over time.
Wood, Vinyl, Aluminum, and Fiberglass Bay Units
Each material presents unique challenges. We handle them all. From rotted wood restoration to vinyl sash replacement, from aluminum frame resealing to fiberglass hardware repair — our team is trained across all window materials commonly used in bay and bow window construction.
Single-Pane and Double-Pane Configurations
Whether your bay or bow window uses traditional single-pane glass or modern insulated double-pane units, we offer expert replacement and repair. We resolve fogging, seal failure, cracks, and thermal inefficiency — all while preserving your home’s comfort and visual appeal.

Frequently Asked
Questions
Can you repair just one section of my bay window?
Yes! We can replace individual glass panels, repair specific operating units, or address localized damage without affecting the entire bay window assembly.
How long do bay window repairs typically take?
Most repairs are completed in 4-6 hours. Complex structural work may require 1-2 days. We provide accurate time estimates during our initial assessment.
What's the difference between bow and bay windows?
Bay windows typically have three panels at sharp angles (usually 30-45 degrees), while bow windows have four or more panels creating a gentle curve. We repair both types with equal expertise.
Do you offer bay window repair near me in the Chicago suburbs?
Yes! We serve all of Chicagoland and surrounding suburbs within a 40-mile radius of our Wheeling location, including Naperville, Evanston, Schaumburg, and Oak Park.
Is it cheaper to repair or replace a bay window?
In most cases, repair is significantly more affordable — often costing 60–80% less than full replacement. We’ll inspect the damage and advise you honestly on the most cost-effective option.
Ready to Bring Your Bay Window Back to Life?
Scheduling your repair is quick, and getting it done is even easier. No upsells. No pressure. Just clear communication, skilled technicians, and results you can see and feel. Whether it’s one foggy pane or a full bay structure that needs attention — we’ll take care of it.
