Traditional sash and case windows can often be repaired without replacing the original frames. This Edinburgh-focused guide explains the faults that commonly affect period windows, the repair options usually considered, and the information needed for an initial assessment.

Common sash window repairs
- Broken or worn sash cords — the sash drops, feels unusually heavy or will not stay open.
- Sticking or painted-shut sashes — paint build-up, swollen timber or damaged beads restrict movement.
- Rattles and draughts — gaps around the sashes allow cold air, dust and external noise into the room.
- Localised timber decay — moisture commonly affects sills, lower rails, joints and glazing bars.
- Failed putty or loose glass — deteriorated glazing details can allow water into the timber.
- Worn pulleys, weights and ironmongery — mechanical faults stop the window balancing and moving correctly.
How a repair enquiry works
1. Describe the symptoms
Explain how many windows are affected, what each window is doing, the Edinburgh area or postcode, and whether the property is listed or within a conservation area. Photographs of the whole window and any visible damage are useful.
2. Assess the condition
A proper assessment should distinguish routine mechanical faults from moisture-related timber damage. It should also establish whether localised repairs can retain the existing window.
3. Agree the appropriate scope
The recommended work may include cord and weight repairs, easing and adjustment, replacement beads, glazing repairs, timber splicing or draught proofing. The quotation should explain what is included before work begins.
Repair or replace?
Replacement is not automatically necessary when a sash window sticks, rattles or has a damaged section. Many faults are limited to cords, beads, putty, ironmongery or localised timber. The right decision depends on the condition of the individual window, the extent of decay and any planning restrictions affecting the property.
Listed buildings and homes in conservation areas require particular care. Read our listed-building sash window guide before considering alterations or replacement.
