Example work, explained
Repairing a sash-window mechanism
- The problem
- A sash sticks, feels unusually heavy or will not stay in position. Worn cords, fittings, paint build-up or timber damage need different repairs.
- The work involved
- The joiner checks the window and agrees a repair suited to its condition, such as replacing a cord or adjusting fittings. Timber restoration, glazing and changes to appearance are scoped separately.
- Checks and next steps
- Check movement, balance and closing, and explain any remaining timber, glazing or finishing work. The repair should suit the existing window and property requirements.

Questions about window, door & carpentry repairs
Does a broken sash cord require a new window?
Not necessarily. The operating components may be repairable if the surrounding window is sound. Its condition needs assessing first.
Can you repair windows and doors instead of replacing them?
Adjustment, hardware or seal repairs may restore operation if the frame is sound. We assess the condition and available components before explaining repair and replacement options.
