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 existing finish and any requested paint work need to be identified in the quote. A local patch may remain visible beside aged coatings. Hazardous paint removal is excluded, and an exact colour or texture match cannot be promised from photos.
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.
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.
