Hi, I just bought a 3 family home in Mass.One of the bathrooms has 4x4 tile in the shower/tub.In the corner the vertical joint has mildew,wich the tennat says she can't remove?Its in the grout. I may need to remove and replace this grout.Can you give me steps for removing the old grout,and how to replace the new grout.I have never done grout work before?Thanks:cool:

I am in the middle of a massive whole house remodle and have run into a snag. I am having issues with the bathroom floor. The house was built in the 50's so you know it's built like a brick. The whole bathroom was done in pink tile, from wall to floor. (eeew) The walls have been taken down to the studs. The subfloor has major water damage where the tub was so I have to replace it. The floor is 1"x1" tiles with about 1" of mortar under it (let's not forget the wire mesh). I can't use a sledge, I'm not sure how sound the joists are. A hammer isn't powerful enough. I've also tried a pick ax which is working a little. But it's taking forever... I've subed out the plumbing and they are due to start next week. At the pace I'm going there's no way I'll be done by then. Any sugestions would be greatly appreciated... :rolleyes:
