The fixing arrangement can change with the mounting style. Handles and opening sections may restrict clearance. Send a wide view of the window and the bracket instructions so the intended layout can be reviewed before marking fixing positions.
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 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.
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.
