Sash Window Spiral Balance Repair

 

Professional Sash Window Spiral Balance Repair & Spring Replacement

If your sash window is difficult to open, drops shut, will not stay open, or feels stiff and heavy, there is a good chance the spiral balance system has failed or worn over time.

At NJS Sash Windows, we specialise in sash window spiral balance repair, helping homeowners restore smooth operation without the need for full window replacement. A faulty balance spring can make even a good-quality sash window frustrating to use, but in many cases, a professional repair gets it working like new again.

What Is A Sash Window Spiral Balance?

A sash window balance spring (also known as a spiral balance) is fitted discreetly into the side recess of the sash window frame. These slim balance tubes help support the weight of the sash, allowing the window to open and close smoothly without dropping.

Unlike traditional sash cords and weights, spiral balances use a spring tension system to support both the top and bottom sash.

Over time, these systems can wear out, lose tension, snap, or fail completely.

Signs Your Spiral Balance Needs Repair

You may need a sash window spiral balance repair if:

• Your sash window drops shut unexpectedly
• The window will not stay open
• One sash feels heavier than the other
• Opening and closing feels stiff or uneven
• The sash becomes difficult to lift
• The balance spring has snapped or failed

Ignoring the issue can put additional strain on the sash and surrounding frame.
