Contractor. Contractors typically bill by the hour or job, and there is usually an agreed-upon fee, so tipping is not required or expected. I do find that the occasional breakfast and/or lunch for the crew is always appreciated and goes a long way toward encouraging timely results.
How much tip do you give a contractor?
Contractors (electricians, plumbers, etc.)
"However, if they do anything extra or spend more time than expected, a tip is always appreciated, with the minimum being $20."
Is it customary to tip handyman?
The sum most frequently mentioned as an appropriate tip for a handyman is $20. Other recommended amounts include the equivalent of one day's pay or 10-15% of the total charge (for a large job). For smaller tasks, many homeowners round up the bill, for example paying $100 for a bill of $85.
