Do you let folks you don't know into your home without a mask?

I'm in the process of gearing up for a home remodel. My spouse and I are vaccinated and we live in an area that is highly vaccinated. My spouse thinks I'm being a little over the top in insisting contractors wear a mask in my home. This wasn't an issue until today when he let one in without a mask. Up until now, all have been respectful and have come masked. I wasn't there when he first arrived but when I came in and saw him I let him know that we wouldn't be using his company and that we didn't need to waste each others time. I am older and at high risk and even though I understand that the vaccine is highly effective I still feel it's disrespectful to enter someone's home without a mask as a business person. I know that life is moving along but am I still the only one who isn't really ready to embrace letting my guard down yet.
