Sash Cords and Pulleys Maintenance Specialists in Bristol

Sash cords and pulleys are a crucial part of how traditional sash windows function, and when they fail, the window can become heavy, jammed, or unsafe. Over time, cords fray or snap and pulleys seize, making it difficult to operate your windows properly.

At Bristol Sash Window Services, we provide professional sash cords and pulleys repair services across Bristol, restoring smooth, balanced, and safe operation to traditional sash windows. Whether you have Victorian timber sashes or 1930s joinery, we’ll get them working like new again without changing their appearance or character.

Why Sash Cords and Pulleys Fail

Sash windows rely on a simple but effective counterweight system. Each sash is attached to a cord, which passes over a pulley and connects to a hidden weight inside the window box. When cords fray, break, or detach (or if pulleys seize) the sash becomes unbalanced, heavy, or unsafe to use.

Common signs your cords or pulleys need attention include:

  • Windows dropping shut suddenly
  • Sashes that are too heavy to lift
  • Frames that won’t stay open or closed
  • Windows rattling or jamming in place

If you notice any of these problems, timely repair will prevent further damage and extend the life of your windows.

Our Sash Cord Replacement Process

We use time-tested techniques to replace cords and service pulleys while preserving the original joinery. Here’s how it works:

  1. Assessment and disassembly – We remove the sashes carefully and inspect the internal weight system.
  2. Cord replacement – Worn or broken cords are replaced with new, high-strength sash cords matched to your window size and weight.
  3. Pulley inspection and lubrication – Pulleys are checked, cleaned, lubricated, and replaced if necessary to ensure smooth operation.
  4. Counterweight rebalancing – We ensure weights are properly balanced so sashes stay in place at any height.
  5. Reassembly and finishing – Sashes are refitted, adjusted, and tested for smooth, safe operation.
