Floor Cleaning Service?
 

I know this topic was talked about last spring, but darned if any of my searches are successful, I am probably using the wrong key words,
I need to hire a ceramic tile cleaner -
our grout is looking dirty in several places and I want to get it cleaned and then sealed -
I bought a Hoover hard floor scrubber, and was going to do it yesterday before I drove back to NC, but of course it would not work, and the box had been hauled off that morning,
so now I have to hire someone, I can't leave it to do when we visit at Christmas, might interfere with the play time,,,

any suggestions?
Much Appreciated,
