Services
Sash window draught proofing
Our draught-proofing service enhances energy efficiency by sealing gaps in sash windows using modern materials. This process reduces heat loss, lowers energy bills, and minimises external noise. Ideal for historic properties, it maintains aesthetic integrity while improving thermal performance.
Box frame repairs
We rebuild damaged box frames with precision, extending the lifespan of sash windows. Using durable hardwoods and traditional joinery techniques, we restore structural integrity. This service prevents further decay and ensures smooth window operation for decades.
Sash cord replacement
Replacing worn sash cords with pre-stretched nylon ensures balanced window function. This prevents sagging and improves ease of use. We match cord specifications to window weight for optimal performance and longevity.
Window sill replacement
We replace rotten external sills with hardwood equivalents, preventing water ingress. This protects window frames from moisture damage and maintains structural stability. Each sill is custom-fitted to match original designs.
Putty repairs
We repair window putty using either traditional lime-based compounds or UV-resistant polymer alternatives. This secures glass panes while preventing cracks and discolouration, preserving both function and appearance.
