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.
Separate similar bolts using the instruction labels rather than appearance alone. A fastener that is too long can damage a desktop. Keep spare parts and packing information until the assembly is checked and any supplier shortage has been resolved.
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.
