Shower wall water infiltration: Will dehumidifier help?

Postby shababak » Sun Sep 13, 2009 6:43 pm


One of the shower stalls in the apartment/condo was inspected by the home inspector and mentioned to have "water infiltration" (measured by the moister meter) behind the wall's ceramic tiles. He mentioned that water has probably dampened the wall behind the ceramic tiles, since the grout wasn't properly sealed.

Will it be possible to fix this by putting a heavy-duty dehumidifier + fan inside the shower stall for a week or so? Then seal the grout to prevent any additional water from penetrating behind the tiles.

No the de-humidifier will have little or no effect on dampness behind the tiles. You may have more success by locating it in the room where damp was detected.

I agree with stoneyboy...I would advise for you to contact a damp specialist to take a look at it. A good place to start would be the PCA (Property Care Association). They are the governing body for all damp proofing contractors and they have a directory of approved contractors within your area.
