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.
Show the full opening and explain the intended mounting position. Handles, opening windows and the depth of the recess can interfere with the curtain or fittings. The final layout should be checked against the product before any drilling is agreed.
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.
