mold on bottom corner grout?

hi, ive searched and read thru some other threads about mold on grout. i didnt think it was really that serious but after reading some replys, im kinda worried. i have some black mold on the grout connecting the side and bottom tile of my shower stall. i used the kerdi shower kit. i plan on taking out the black grout. how would i know if its a more serious problem like being wet behind the tiles? should i take out the tiles around it too? thxs

That shower would be a little more than a year old now, right, Tony? The mold a new problem, or has it been there for a while?

A good photo of the area would certainly help.

You don't wanna be removing tiles from a Kerdi shower unless it's absolutely necessary. Gonna cause a whole lotta work if you do.

My opinion; worth price charged.

I believe it's just a maintenace issue,i would use a stone cleaner,for soap scum, and nylon scrub brush, and clean it let, it dry and reseal it.

It looks like it could be harboring water, but still, if there's soap scum it could be trapping it.Clean it well and see if it stops it.

Hi Tony

I'm with Dave. Get the tile & grout cleaned first. You may also need some fresh caulk at the perimeter corners. RTV silicone works the best. Most of the acrylic silicones tend to peel away after a short period of time. This allow the soap to enter the crevices and give the mold/mildew something to feed on.
