So we found out the renter in my moms place is moving out this summer, so I went downstairs to do some measurements for putting in tile and stuff before she starts looking for another renter. The bathroom clearly has a small leak in one of the pipes for the tap, and I can see mold on the wall and side of the vanity. It isn't lots of mold or anything but given where it is and the obvious drywall damage, it could have been leaking for a year or more and have had no one notice.

Any suggestions for dealing with this?

My thoughts are pull the vanity out, rip the drywall and lino out and see where it extends to and keep ripping stuff out till all the mold is gone. I understand how to protect myself and how to deal with mold in small amounts but is there any legal requirement (or self preservation requirement) that says I can't/shouldn't do it myself if there is too much?

I know we could call in a company to deal with it, but the budget right now is kinda low, especially considering the rental market in Calgary isn't booming so it might be sitting Vacant for a few months even after it is done. If there is no option, then I assume she could get it tacked onto her mortgage, but I doubt that would be pretty since when my dad died, her credit got right fataed up.
