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.
Once fitted, the blind should be checked for the intended travel and clearances without forcing its mechanism. An incorrectly sized product or supplier fault may need a replacement. Fitting work does not include repairing every internal blind mechanism.
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.
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.
