Welcome to our window sash repair portfolio, where we showcase real projects completed across Chicago and the surrounding suburbs. At Window Quality Works, we specialize in restoring window sashes to full working condition — whether they’re stuck, damaged, rotted, or misaligned.
Our goal is to help homeowners keep their original windows functional, efficient, and visually appealing, all while avoiding unnecessary full replacements.
Common sash problems we repair
Over time, window sashes can become difficult to operate, damaged by moisture, or simply worn out. Below are the most common issues we fix to restore smooth, safe, and efficient window function. We deal with:
-
Stuck or painted-shut sashes
-
Broken or frayed sash cords
-
Rotted wood at the sash bottom rail or corners
-
Loose or rattling sashes
-
Sash that won’t stay open (balance failure)
-
Cracked glass within the sash
-
Misaligned or off-track sashes
-
Water infiltration through gaps
We work with both double-hung and casement windows, in wood, vinyl, and aluminum frames — including many historic and custom-built homes.
Why repair a sash?
Window sash repair is a smart and cost-effective way to extend the life of your windows without compromising their original look and function. Sash repair:
- Restores functionality and airflow.
- Prevents drafts, leaks and heat loss.
- Preserves original windows in historic homes.
- More affordable and environmentally friendly than full window replacement.
By fixing sash problems early, you improve comfort, protect your home, and avoid the expense of unnecessary replacement.
