A window above stairs or behind fixed furniture can require a different access plan. Show the surrounding room as well as the blind. Suitability is assessed before scheduling, and inaccessible or unsupported work is not assumed to be covered.
A blind ordered for a recess needs more than a rough outside width. Provide the supplier dimensions and opening measurements, including depth where relevant. Installation should not rely on cutting or adapting an unsuitable product after it arrives.
A narrow trim or existing hole does not automatically provide adequate support. Wall construction, bracket loading and safe drilling locations need consideration. Explain known services and restrictions, and avoid removing finishes merely to provide a quotation photograph.
The agreed service covers measured product/bracket compatibility, supported fixing, operation and mandatory cord safety. Exclusions: Electrical motors/wiring, specialist custom manufacture, unsafe/incomplete cord systems, inaccessible work.
