Do you tip cabinet installers?
In general, home service providers such as electricians, plumbers and contractors are professionals who don’t expect tips. They expect to do a job for you for the specific price they quoted. Of course, they may appreciate a tip for a job particularly well done or for which they’ve gone beyond what’s normally expected, such as completing the project early or under budget. Even better than a tip, it’s always appropriate to leave a positive review online after a good experience.
