Possible Mold?

I live in a condo and I think the unit above me may have had a leak in their bathroom. The ceiling in my bathroom has bubbled out. It was wet and soft at one point, but has now dried up. However, the bubbling is still there. I'm concerned that this wet patch could possibly turn moldy over time. There is no discoloration as of yet, it's been this way for a few months.

I'm wondering if I need to have this looked at before mold sets in. Also, aside obvious discoloration, are there any other signs to look for possible mold? I'm not sure how long it takes to set in. My son and I both have asthma so this is a great concern for me.

Any help would be appreciated.

HI Sarah,

You need to find out if the water came from a one time flood or if was running over a period of time.

if was a one time flood mould would not have had enough time to form. If it has been leaking over a period of time, mould could be forming . If you are concerned because of your asma, rent a HEPA filter to clean the hair while you are having the damaged area looked into.

Good luck.

I would suggest that you check with your condo corporation by-laws and the condo corporation committee. Maybe a discussion should also happen with your lawyer to find out who would be responsible for the repairs as the leak happened in the condo above yours. There could be issues or repairs that could be undertaken through the condo corp and/or your insurance company.

We are currently renovating a condo from scratch. We had noticed that the next door Neighbor bathroom witch is a reverse from our floor plan was leaking. We have notified the neighbor witch he was not aware that is bathtub was leaking. He was tankful that we had showed him, and he will have his renovations done soon. Maybe if you would just go see your upper neighbor, it would salve the problem. If you would have any more questions, it would be a pleasure to answer you.

Quite possible this was a toilet or tub overflow, given the fact that water did come through your drywall in the ceiling there shouldn't be anymore up there, mold shouldn't grow in the ceiling since it's quite warm and dry in that area.

Good luck,

To be safe I would check it out as soon as possible. Find where the water damage came from and over time the mold could build up and cause you more damage than you think, as mold is a very dangerous substance once airborne.

Hi Sarah,

The owners of the condo units that we service locally are responsible for the ceiling of the unit below. Several of the owners have had us change out their older hot water tanks before the tanks started to leak and cause any damage to the condo below. We also placed the new tanks in trays for additional water damage protection.

I would check your contract to see who is responsible. In any case, I would have the ceiling checked out. We have done some bathroom renovations where there was no visible signs of mold on the outside of the wall but there was mold in behind. The worse that we have seen was a recent renovation that we did....mushrooms growing on the shower walls!!!

Thank you all for the replies and suggestions.

This brown patch is also in my bathroom, but not on the ceiling. (Sorry if the image isn't clear.) It's on the wall beside my medicine cabinet. It's been there for months, possibly a few years.

Could this be mold?

I would hire a contractor to remove the section of dry wall and have a full view of what lies beneath, the condo corp. should cover the cost of this repair.

This will allow you to see were the leak is coming from and see if there is any mould growing.
