Work should not require removal of glass, glazing beads or seals. Show how close the defect is to those components. Glass replacement, seal work and specialist glazing repairs are excluded rather than treated as incidental parts of a small frame job.
A stiff handle or difficult opening may concern hinges, catches or other hardware rather than the frame finish. Describe how the window operates. Suitable hardware work belongs to its own service, and a cosmetic frame patch will not correct that mechanism.
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.
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.
