blind installation can be appropriate when a visible maintenance item is worn, loose, damaged or no longer works as expected. The measured product, mounting style, substrate and complete operating-safety system must be suitable before installation proceeds.
Signs: a practical repair list needs the affected item and its condition identified or a visible maintenance item is worn, loose, damaged or no longer works as expected. Causes: conditions that need direct review before a repair option is chosen or loose compatible components or incomplete prior work.
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 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.
