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.

About neighbourhoods and postcode matching
August 2026 ONS postcode data identifies boroughs sharing an outward district. Named centres use London Plan references; neighbourhood postcode examples use local address sources. Neither defines an exact neighbourhood boundary. Even a full postcode entered here is matched only by its first part.
Where a dedicated local service guide is available, we link to it. Other places lead to the relevant borough guide with your selected area carried into the enquiry. Your full repair address is needed when arranging attendance.

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.
How much does sash window repairs cost?
Access, timber condition and the repair extent determine the quote. Specialist restoration and decoration are separate unless included. We provide a quote including VAT for the agreed work.
