A painted wall surface does not reveal all of the construction behind it. Share any known wall details and nearby services. Installation depends on suitable support and safe fixing locations, not simply finding a plug that fits an existing hole.
Furniture, pelmets and high or awkward positions can limit safe access. Show the room around the window and mention any staircase or obstruction below it. Unsupported high-access work is outside this service and must be identified before booking.
Long rods or tracks may require a specific support layout. Provide the manufacturer instructions and desired width. Omitting an intermediate bracket to improve the appearance is not appropriate when the product relies on it for support under normal use.
The agreed service covers non-powered rods/tracks, compatible brackets, positioning and operation checks. Exclusions: Electrical motors/wiring, unsuitable substrates, unassessed cord hazards, unsupported high access.
