New House in NE Ohio, Mold Worries


Hi all, Love this forum, very informative!

I recently bought a house built in 1955. Its a cape code style home with an upstairs bathroom. When the previous owner re-did the upstairs bathroom he did a drop ceiling. (dont worry I plan on redoing it ) My Worries though. When I take a shower all the moisture has to go right up into the attic.
My Attic has 5 vents, a mushroom vent right above my bathroom, two box vents, and two gable vents.

Nobody in the house is sick, but Im afraid I have a mold problem up there. I had a mold test done (on the first floor), and it came back with this: Cladosporium, but from what I understand that is just a common type of household mold. Is it anything I need to worry about?

Thank you.

Why would the bath air go into the attic? The post lacks details.
Is the drop ceiling the only ceiling?
Is there a bathroom exhaust fan?
If not, put one in. Now!
Did you check the attic for moisture issues?
If you haven't, do it now!
I don't understand the reasoning here. You know moisture can create mold and you think the attic is full of moisture.
What's keeping you from investigating this seemingly obvious problem?
I understand a person who has seen the problem and wants to rectify it.
I don't understand this.

Hey Ron,

I apologize for the bad post, did it quickly without a proof read. Yes the drop Ceiling is the only ceiling, goes right up into the attic. And yes Ive looked up in the attic and dont see anything major, but I'm really not sure what to look for. (black marks on the ceiling?, im not sure) And with a drop ceiling how do I install a vent van, there is a "mushroom" vent nearby so I can go to that, and I can get power, I just dont know how to insert a vent van into a drop ceiling. Do I just need to replace it with greenboard, and go from there? Thank you for your reply!

Lose the drop ceiling. Install a bathroom vent fan exhausted to the exterior. Install a vapor barrier, insulation and a water resistant or mold resistant sheetrock.
The setup you currently have sounds like a major heat losshole.

Thank you.
Cladosporia come in a couple of different varieties. None of them are particularly associated with wet buildings. If the test didn't show any above average levels of Stachybotrys then you likely have no problem. You need to know this. Practically all mold test kits from the hardware store will show positive results. They have to. Molds are literally everywhere. Without a normal background test to compare to, you have no idea whether the levels are high, low or normal. With a home made mold sample test you don't have an average for comparison. More people suffer from worry induced by media hype about mold rather than any real mold exposure.

If this is of any help, we were in a similar situation when we lived in a house built in the early 1900’s. Installing a fan would have destroyed the ornate ceiling and we needed something because the bathroom was long, with the window at the far end from the tub / shower. Both my son and I had some challenges with allergies, so we worried about mold. A contractor friend suggested we be proactive and leave the window open for half an hour after bathing.
We both use quality air purifiers so that we do not need to worry about breathing problems or weakening our immune systems. After checking out way too many lousy air cleaners, we created a website that features the ones we thought the best. There is a lot of information on . It may be of use to you.
