Estimates are not exact (though they are usually close). if you want a quote I would need to base it on a significantly higher hourly rate to make up for surprises, I don’t know what’s going on inside of walls, or what surprises might come up and set everything back or ahead.
I do not mind at all if clients want to save by helping with clean up, having supplies ready, or giving a hand (depending on the job). Since its hourly it’s to your benefit, or I could happily do it all.
