Hello,

While removing wallpaper I loosened base molding tiles. I found some areas where there must have been some water problems in the past. There appears to be no sheetrock behind some of the base tiles. What can I do to secure the base molding tiles?

I appreciate any suggestions!

Depending on how extensive the damage is, (and hopefully it is in a dry area and not in a shower) after removing the base tiles and cleaning them, you can cut strips of 1/2" concrete backer underlayment and fasten them to the studs and reapply your base tiles. Make sure you are prepared to deal with mold behind the sheetrock, as with any water damage it will grow.

 

Providing the drywall is in a dry area [not the shower/tub encloser] you can use drywall if the damage extends beyond the tile.

 

I'll attach image showing repair a tile guy did 20 years ago to this same problem wall. I'm guessing it was shower spill-over that caused the need for repair.

I'm just wondering - since mold was mentioned and there was a water leak 8 years ago behind this wall with problem tile. How bad ($) could it get?

Much thanks,

No good way to know until you open it up, might just be minor. If it was major you'd probably have some evidence of it but you just don't know until you look.

 

Fun - This. House.

SideTile - - I removed a loose, narrow end tile and find the adhesive had let go of the sheetrock. I have no idea why there is a gap where sheetrock was not mudded together! This is the first view of this I've had. Been in the house almost 30 years. My intentions are to use Loctite Power Grab to adhere the tile to the sheetrock. Regrout and seal (silicone seal?).

BaseTile - It wasn't as bad as I thought. The sheetrock had cracked loose. It hadn't dissolved as it from water. (Not that I'm real experienced there though)
My thought was to put sheetrock behind the tile (screw it to wood) then use PowerGrab to adhere tile to sheetrock, include some extra grout to help sturdy the tile to floor and call it done.

Any other words to educate me here?

Thanks,
