Essential timber window maintenance is highlighted in a Fact Card from the British Woodworking Federation Timber Window Accreditation Scheme.

Coating systems and hardware get particular attention. Care of the profile coatings includes the removal of mould, algae and natural resin exudation plus the introduction of a planned cleaning and washing programme.

Checking the locking system and hinges, as well as general cleanliness of all components, is also advised.
