Window Repair in St. Louis, MO: Sash Cords, Screens, and Drafts

Window repair in St. Louis, MO covers a wide range because the city has a wide range of windows — original wood sash in Lafayette Square and Soulard, mid-century aluminum in Affton, and newer vinyl across the County. Each fails differently, and most failures are repairable without a full window replacement. Here's what we fix, and when replacement is the better call.

The window repairs we handle

• Broken sash cords on wood double-hungs (the window won't stay up)
• Balance and spiral replacements on newer double-hungs
• Window screen re-meshing and full screen replacement
• Sash and frame repair for rotted or loose wood
• Draft sealing and weatherstripping around sashes
• Glass and pane replacement (we'll refer if it's a sealed insulated unit)

All under our doors, windows and locks service.

The sash cord fix

In older St. Louis homes with wood double-hung windows, the sash is counterbalanced by a weight on a cord inside the frame. When the cord breaks, the window crashes down and won't stay up. The fix is replacing the cord (or upgrading to a modern chain) and re-weighting. It's a precision job that saves a window that otherwise seems 'broken' and headed for replacement.

Screens: re-mesh, don't replace

A torn screen doesn't need a whole new screen frame. We re-mesh the existing frame with pet-rated or standard mesh, and we can upgrade to solar mesh for sun-facing windows. Full screen replacement when the frame is bent or broken.

Drafts and weatherstripping

A drafty window is usually a weatherstripping failure, not a window failure. Replacing the weatherstrip and sealing the gaps at the frame can cut drafts dramatically without replacing the window. We pair this with caulking the exterior frame for a full seal.

When to replace instead

A window needs replacing when the frame is rotted through, the sash is warped beyond repair, or the sealed insulated glass has fogged (a sealed-unit replacement, which we'll refer to a glass specialist). We'll tell you honestly when repair is a waste and replacement is the better spend.
