Spiral Balance Replacement
Sash Window Spiral & Coil Balance Replacement in London.
Spiral Balance Replacement
Over time, the spiral balances in your sash windows can wear out, losing the tension needed to smoothly open and close your windows. When this happens, your window may feel heavy, refuse to stay open, or slam shut unexpectedly. These are all signs that it’s time for a spiral balance replacement.
Our expert team specialises in repairing and replacing spiral window balances for all sash window types. We use high-quality, long-lasting balances that are perfectly sized and tensioned for your frame, ensuring smooth operation for years to come. Whether your sash is tilt or non-tilt, timber or uPVC, we have the expertise to get it working like new again.
Tilt and Slide Window Repair
Tilt and slide windows are a modern, versatile option that combine ventilation with ease of cleaning, but when the balance systems, track, or locking mechanisms fail, they can become difficult or dangerous to operate.
Our repairs restore full functionality, allowing your windows to tilt inwards for cleaning and slide smoothly for ventilation. We only use quality replacement parts and precision adjustments to ensure lasting performance.
Coil Balance Replacement
If you have modern sash or tilt windows, they may be fitted with coil balances (also known as constant force balances). These clever spring mechanisms allow your windows to glide effortlessly, but like all moving parts, they can wear out or break.
A failing coil balance can cause sticking, uneven movement, or even complete window failure. Our coil balance replacement service is designed to restore your window’s performance quickly and efficiently. We source and install manufacturer-grade replacement parts, ensuring compatibility and durability.
