SASH WINDOW COST GUIDE
The cost of replacing a timber sash window in Scotland depends on far more than the size of the opening. Timber species, glazing specification, mouldings, historic detailing, access, decoration and whether the property is listed or in a conservation area can all affect the final quotation. This guide explains the main cost drivers so owners can compare repair, refurbishment and replacement on a like-for-like basis.
Repair before replacement
Complete replacement is not always the best starting point. Traditional sash windows are designed to be repairable, and sound original frames can often be retained using targeted sash window repairs, timber splicing and sill repairs or a fuller refurbishment. We assess condition before recommending replacement.
What affects sash window replacement cost?
Important factors include overall dimensions, number of panes, glazing-bar pattern, hardwood or suitable durable softwood, single or double glazing, ironmongery, access and scaffolding, external finishing and the amount of surrounding joinery or mastic work required. Bespoke curved heads or unusual historic profiles can also add fabrication time.
Replacement and double glazing
Where new windows are appropriate, glazing specification can make a significant difference. Read our double glazed sash window cost guide and our information on heritage slimline double glazing. For traditional buildings, the visual effect of the glazing and glazing bars matters as much as headline thermal performance.
Listed buildings and conservation areas
Consent requirements can influence specification and cost. Our listed building and conservation window guide explains why retaining original fabric is often preferable and why like-for-like detailing matters.
Getting an accurate quotation
A meaningful price requires inspection of the existing windows and an agreed specification. We provide quotations for appropriate projects across Stirling, Falkirk, Fife, Perth and surrounding areas rather than publishing misleading one-size-fits-all prices.
