Routine inspection and modest maintenance can prevent small defects from developing into expensive timber repairs. This guide outlines practical checks for owners of traditional Scottish windows.
Inspect paint and putty
Look for flaking paint, cracked putty, open joints and bare timber, particularly at lower rails and sills. Water should shed away from the building rather than collect against joints.
Check operation and balance
A sash that drops, jams or needs excessive force may have a broken cord, damaged pulley, paint build-up or distortion. Do not force it: damaged glass and sudden movement can cause injury.
Keep drainage and ventilation working
Clear dirt from accessible sill areas and check for trapped moisture. Maintain adequate indoor ventilation to reduce condensation, and investigate persistent damp rather than simply repainting over it.
Plan safe specialist maintenance
Upper-storey windows, lead-based historic coatings and fragile glass can present hazards. Use competent tradespeople for work at height, glass replacement and intrusive timber repairs.
Keep a simple record
Photograph defects, note dates of repairs and record the products used. This is especially helpful for listed buildings and for comparing changes over successive winters.
