What Are Sash Cords and Pulleys?

In traditional double-hung wooden windows, sash cords and pulleys are part of a counterweight system that allows the window to glide up and down easily. Over time, cords can snap, pulleys can rust or jam, and counterweights may shift or fall.

Common Signs of Cord or Pulley Failure:

The window slams shut or won’t stay open
The sash is stuck or difficult to move
You hear loose weights rattling inside the frame
Cord is visibly frayed or broken

Our Sash Cord & Pulley Repair Process

Inspection of Interior Cavity
We open the window casing to access the weight pocket and inspect the full counterbalance system.
Cord Replacement
We remove damaged sash cords and replace them with high-strength cotton or nylon cord, rated for long-term durability.
Pulley Cleaning or Replacement
Rusted or seized pulleys are cleaned, lubricated, or replaced with historically accurate brass or steel models.
Counterweight Adjustment
We ensure the correct weights are attached to each sash for smooth and balanced operation.
Reassembly & Testing
After repair, we close the pocket, restore trim, and test the window for full functionality and ease of use.
