A finish that repeatedly stains or breaks down may point to unresolved water entry. Explain the history rather than requesting another cover-up. This service does not include leak diagnosis, sash restoration or window replacement, and cosmetic work may need to wait.
A small surface chip or finish defect can be reviewed when the surrounding material is sound. Show the whole window as well as the mark. The service is deliberately limited and does not imply that any damaged window frame can be restored.
Soft, crumbling or deteriorated timber is different from a surface blemish. Explain any known water exposure and show the surrounding area. Rot remediation has a separate repair scope, while a severely deteriorated frame may require a specialist replacement assessment.
The agreed service covers small cosmetic timber/frame finish repairs after condition and access review, without disturbing glass or the glazing system. Exclusions: Frame replacement, structural joints, glass/beading removal, seals, sash restoration, rot remediation (existing separate intent), hazardous coatings.
