Hello AT, Stupid question from someone with no handy gene whatsoever, but who do I call to get someone to regrout the tiles in my bathroom? It's great vintage, subway tile, but I'm worried the water is starting to seep through to the wall, and I have no idea who does this - a plumber? A tile guy? A general handyman? Thanks, Lisa Dear Lisa, Be bold! You can do it yourself with an off-the-shelf tube of tile caulk from your local hardware store. You can either to a patch job or really dig out the old stuff and start from scratch.
