Send photographs of the existing joints, loose parts and instructions if the desk is partly built. A cross-threaded bolt or damaged insert can prevent correct tightening. Forcing the joint may make replacement parts necessary instead of allowing a simple adjustment.
A separately purchased desktop may not share the fixing pattern or supported dimensions of the base. Provide both product specifications. Do not assume that drilling extra holes or shortening the top is included in a straightforward furniture assembly quote.
Explain whether the desk uses a manual adjustment or a powered system. The advertised service covers suitable mechanical furniture assembly. Wiring changes, power-point work and motor or controller repairs are not included simply because they are part of the same workstation.
The agreed service covers manufacturer-directed assembly of supported desk frames, tops and supplied furniture hardware. Exclusions: Electrical installation, cable relocation, custom joinery, motor/controller repair.
