Sash Overhaul Services in London
Bring Your Sash Windows Back to Their Best
At London Glazing and Sash Services, we provide sash window overhaul services across London, helping restore the smooth operation and comfort of traditional timber windows. If your sash windows are sticking, rattling, letting in draughts or refusing to stay open, our team can assess the problem and recommend the appropriate repairs.
An overhaul focuses on improving your existing windows while preserving their character. From replacing worn sash cords to adjusting the opening mechanism and fitting draught seals, we tailor the work to the condition of each window.
What Does a Sash Window Overhaul Include?
Years of use, paint build-up and worn components can make sash windows difficult to operate. Our sash overhaul service addresses these everyday problems, helping your windows open, close and sit more securely within their frames.
Depending on the condition of your windows, the work may include:
- Replacing broken or worn sash cords
- Checking pulleys and adjusting sash weights for balance
- Easing and adjusting sticking sashes
- Replacing worn staff beads and parting beads where required
- Fitting suitable draught-proofing seals
- Checking catches, fasteners and window furniture
We assess each window before recommending the scope of work. Where timber decay, damaged glass or more extensive repairs are identified, we explain the options so you know what is needed.

Reduce Draughts, Rattles and Sticking Windows
Traditional sash windows should be practical to use as well as attractive. Gaps around the sashes, worn beads and an unbalanced mechanism can leave rooms feeling draughty and make opening your windows a struggle.
- Draught-proofing – helps reduce unwanted air coming through gaps around the moving sashes.
- Smoother operation – easing and adjustments help windows slide more freely.
- Improved balance – correctly balanced sashes are easier to lift and should stay in position when opened.
- Reduced rattling – improved fitting and suitable seals help limit movement within the frame.
- Preserved character – retain the appearance of your existing timber sash windows.
Our approach is to improve how your windows work while retaining serviceable original components wherever practical.
