At Rotten Window Repair, we focus on window repair and window restoration instead of installing new windows (we do it only as a last resort). Our team is skilled in repairing everything from rotten wood to broken glass, saving you money and keeping your residential windows in great shape. We work with old wooden windows, no matter if they are single‑hung, double‑hung, or casement. We work not only with wood, but also with vinyl and aluminum frames.
Instead of an expensive full replacement, we fix only damaged parts. After a free window inspection, we can suggest replacing rotten wood with new wood, sash repair, window sill repair, or installing a new window in case of fatal breakage. Our goal is to offer cost‑effective window repair so you don’t have to replace the entire unit if it’s not necessary.
Based in Plainfield, IL, Rotten Window Repair provides residential window repair and restoration in Chicago and surrounding suburbs, including Naperville, Aurora, Joliet, Bolingbrook and Downers Grove. We offer free window inspections to assess wood damage, glass problems and operating issues. View our service areas or contact us to check availability at your address.

Looking for Top-Notch Window Restoration Services?
At Rotten Window Repair, we believe that replacing the window is not always necessary! If it’s possible, we repair or restore your windows, and help you save money on replacements. Whether you have a cracked window, foggy glass, damaged sash, or rotten sill, our technicians can usually repair just the affected parts.
Older windows are worth inspecting, but age alone does not mean they need restoration or replacement. Peeling paint, soft or deteriorating wood, drafts and difficulty opening or closing are more useful signs that repairs may be needed. When the remaining structure is sound, targeted restoration can preserve the character of original wooden windows while addressing damaged components.
We work with bay windows, bow windows, casement windows, sliding windows and doors, garden windows, picture windows, single‑hung, and double‑hung windows.

Why Hire Rotten Window Repair?
Cost-Effective Solutions
Our restoration services target only the damaged parts, saving you money compared to a full window replacement. Often we can repair a cracked window glass, rotten sash, or damaged sill without touching the rest of the frame, which keeps your window repair cost under control.
Longevity
We are fixing the issue, not covering up the problem. Instead of using filler or epoxy, we replace rotten wood with new wood. This approach extends the life of old wooden windows and original wood sills, preserving both function and appearance.
Sustainability
We help extend the life of your wooden windows, which can last from 20 to 50 years, or more with proper care. Repairing instead of replacing reduces waste and is better for the environment, especially when restoring historic wooden windows.

Worried about your damaged windows?
We provide a wide list of services, so we can improve window breakage of any complexity. Here are our services:
How Much Does Window Repair Cost?
Most residential window repairs cost $150–$1,500, including labor. The final price depends on the damaged component, window size, materials and whether custom glass or parts are required.
Minor adjustments are usually near the lower end. Hardware, sill, sash and standard glass repairs cost more, while specialty glass or extensive wood damage may reach the upper end.
These prices are general estimates, not fixed quotes. We inspect the window, identify what can be repaired and provide a clear project-specific estimate before work begins.
Types of Windows we work with
Repaired windows and doors can greatly improve your home’s appearance, energy efficiency, and security. We work with:
Awning windows
Awning windows are hinged at the top and open outward, forming a protective “awning” when open. They are perfect for areas that need ventilation even during light rain and are a great option if you need reliable window repair or replacement in compact spaces.
Bay windows
Bay windows consist of three or more panels arranged at angles, extending outward to create additional interior space. They bring in more natural light and provide a panoramic view of the outdoors – we repair and restore bay window frames, glass, and seals to improve comfort and energy efficiency.
Bow windows
Bow windows are made up of four or more panels that curve outward, creating a rounded appearance. They enhance the sense of space and offer a wider view of the surrounding landscape; our team works with bow window repair, including sash, hardware, and glass replacement.
Casement windows
Casement windows are hinged on the side and open outward, making them ideal for tall, narrow spaces. They provide excellent ventilation and a sleek, modern look.
We service casement window hardware, sashes, and seals to restore smooth operation and prevent drafts.
Sliding Windows,
Patio Doors
& French Doors
Sliding windows and patio doors move horizontally along tracks, while hinged French doors swing open. We repair sliding systems with worn rollers, damaged tracks or closing problems, and address hardware, alignment and glass issues in French doors. The recommended repair depends on the door or window design and the condition of its components.
Double-hung windows
Double-hung windows are constructed of two sashes. Both the top and bottom sashes can slide up and down within the frame, offering improved ventilation. You can open the bottom sash to bring in air from below and the top sash to allow air to escape from above. This style is popular in both classic and modern homes, and we specialize in double hung window repairs, sash repair, and balance replacement.
Garden windows
Garden windows extend outward from the home, creating a small, enclosed space perfect for growing plants or displaying decor. They allow for maximum sunlight and add charm to kitchens or other living spaces. We offer garden window glass replacement, frame repair, and sealing to prevent leaks and drafts.
Picture windows
Picture windows are large, fixed windows designed to frame the outdoor view like a picture. They do not open but provide ample natural light and a clear, unobstructed view. Our services include picture window glass repair, foggy glass replacement, and frame restoration.
Single-hung windows
Single-hung windows have a fixed upper sash and a lower sash that slides vertically to open. They are a cost-effective and space-saving option for any home. We repair single hung window sashes, balances, and hardware to extend the life of your existing windows.
Our Window Repair & Restoration Projects.
Why Us?
Rotten Window Repair works with all types of windows, offering repairs and replacements for wooden, vinyl, and aluminum frames. We use precision tools designed for detailed tasks, such as repairing window frames, sashes, sills, window sash balances and hardware, and replacing window panes and glass units without damaging surrounding structures.
Whether you’re dealing with a rotten window, cracked or broken glass, foggy double glazing, or broken mechanisms, our experienced team provides targeted solutions to restore full functionality and extend the life of your windows. We tailor our services to your specific window needs and provide an honest recommendation: window repair, sash repair, or full window replacement only when absolutely necessary.
Windows that stick, will not stay open or no longer close securely may need repairs to the hardware, balances or sash. Drafts, deteriorating wood and moisture between glass panes require different solutions. We identify the cause and explain which components need attention, so you can make an informed decision about repairing your existing windows.

How to Check Your Windows for Repair Needs
1. Look for visible wood and frame damage
From a safe, accessible position, look for peeling paint, visible rot, cracks or gaps around the sash, sill and frame. Note which windows show damage without removing any parts.
2. Check the glass
Look for cracks and moisture or cloudiness between the panes. Note whether the problem affects the glass surface or appears inside the sealed glass unit. Do not touch or press on damaged glass.
3. Check how the window operates
If the glass and frame appear intact, gently check whether the window opens, closes and locks normally. Do not force a stuck window or continue testing a sash that will not stay open.
4. Record the problems and request an inspection
Write down the affected windows and the symptoms you noticed. Contact Rotten Window Repair for an inspection to determine whether the glass, wood, sash or hardware can be repaired separately.
