Do you tip your housekeeper?

Mrs. J
I'm talking about for your home. I plan on it, especially because we've been remodeling and it's pretty dusty, but I was curious if this was standard and if so, how much or what percentage? I've never hired anyone before but a 4 bed 2 bath, 2,700 sq ft house is something I just can't tackle right now at almost 39w.
