Movement at a frame joint or distortion of the opening is outside cosmetic repair. Do not cover or force the affected area to improve its appearance. A suitable specialist should assess suspected structural failure before a local finish repair is considered.
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.
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.
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.
