Mold question

8 Replies

I just purchased my first flip at sheriffs auction but there is extensive mold due to the radiator register pipes bursting over the winter cause no one left the heat on. I plan on gutting the whole lower level (quad level house) but it has some kind of tile installed on the concrete floor. I'm not sure if it's ceramic, porcelain or some other kind of tile but my question is whether the mold would get into the grout or the tile itself? I was hoping to salvage the tile floor. Does anyone know?

No real expertise on this, but if the tile was in good condition, and you want to save it, I don't think there would be a problem. Bleach is probably your friend.....

I would consult with a mold remediation company. They should be able to tell you what has to be done to take care of it. Since the mold spores can spread if not properly handled (a health hazard), you need to have a specialist take care of it. Mold grows and spreads on organic material - wood, drywall, etc. Since grout is porous, it might have some organic material soaked into it that the mold could feed on and it could cause stains that might be difficult to remove.

Have you ever seen mold growing on the grout in a shower? Yes, it can grow on the grout ...

@Gerald K. And @Steve Babiak are correct. The mold can certainly grow on (and in) the grout.

Ceramic or any type of hard baked tiles are considered non-porous. They can be reused provided you remove as much of the grout as possible and then clean them effectively.

If the tile is in good shape and on a concrete slab I wouldn't think it would be a problem. I'd probably just clean it well with bleach and/or baking soda.

But if this is your first go around with mold its probably a good idea to get a mold "expert" to check it out but be careful who you use because a lot of these guys are con artists that will try to scare you and sell overpriced remediations. We had one guy that rolled up in a Ghostbusters van and tried to con us into paying him $7K to use his mystical equipment to fix a fungus problem under a house. He acted like he took samples and got the results back within 24 hours (which I found out is impossible) and "our situation was much worse than he initially thought". In the end my partner and I did it ourselves for about $150 worth of fungicide we bought at a cleaning supply store.

Try to find someone that will just do the testing/consulting with you and isn't also a contractor that does the remediation, this is your best shot at getting an honest assessment of the mold problem. I found a good guy in Tampa by using Angie's list. Or have more than one company come out to assess the problem.

@Travis West ,

To make the @ work, do the following:

Hold down the shift key and type @?

Look below this Window, and you will see a list of names of people that have posted in this thread.

Click on the name of the person that you want notified via an email, that you responded to them.

If you are a Colleague with anyone that has NOT posted in the thread, and you want them to see your post, hold down the shift key, type the @ and the first 4 letters of their First or Last Name.

Then look below this Window and click on that person's name.


Get a mold expert in there to tell you what needs done. My mold expert told me bleach will discolor mold and make, but does not always kill it, especially if it is in a porous material like wood or drywall where you can't see all the mold.


Thanks for the help. That clearly explains why I can't tag anybody using my iPad. Additionally, none of the names are listed "at the bottom" as you suggest.

Since most of my posts are on the run, I will just forgo tagging names in my responses.
