Keep the coffee pot on and offer them soda/pop or ice tea.
I really don’t think it’s normal to tip. But it’s a good idea to be as accommodating as you can. Be there, if you can, to answer questions, but stay out of the way.
Make sure all your stuff is out of the bathroom before they arrive.
Question?
Are any of the first 4 responses contractors? (Just curious)
I am a contractor and spend alot of time in people’s homes. Customarily we are not tipped. Rarely would be a better word. Almost never would be best…
OTOH, hospitality is always appreciated. Water/soda/coffee is always appreciated and fairly common. Less common, but not totally uncommon, is a snack or even lunch. I’ve been invited to have lunch with the homeowner several times. If it’s accpetable that they use your restroom during the day, let them know that first thing in the morning.
(I would probably only offer lunch if they are particularly professional and cooperative. i.e. drop cloths, friendly attitude, sensitive to cleanliness etc)
Another contractor, here. I’ve never been tipped, nor would I expect it. I know I’ve arrived when a post-it tells me to start the coffee pot and the croissants next to it are for me. Those customers take it to the next level, in that we have a relationship beyond business. It’s worth far more than what I’m paid in dollars.
My older brother (about ten years older) has been a conractor his whole life and when I was in HS I would work for him on some weekends and during the summer for spending money.
He was never tipped nor was there ever an assumption or even expectation for one. I think a lot of that is a contractor is sort of out of the “tip sphere” as far as workers goes.
Small contractors rely largely on word of mouth recommendations. If you really want to do a contractor a favor, tell him you will pass on his name to others. That’s where the money is.
