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.
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 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.
