How can you get rid of mold without tearing down walls?

I am interested in buying a house that may have mold.

Is there a way to get rid of the mold if it is in the walls without taking the walls down? And is all mold dangerous?

I don’t know all the details, but, the seller should be responsible for having a possible mold issue taken care of. 1. All molds can be dangerous to people and pet’s. It depends on how much mold is in the living environment and what other health issues a person or pet has. Mold may affect people that have allergies,asthma, immune problems, etc. more than so called healthy people. 2. The seller should be required to have a mold test done by a professional to determine the level of mold spores in the home. 3. If the mold is visible, some kind of remediation needs to be done. 4. Moisture is the necessary ingredient that mold needs to live. (What’s causing the moisture problem?) 5. You don’t have to tear down the walls unless the walls have been compromised by the mold. (I don’t know what your walls are made of.) I can go on an on regarding Mold issues in peoples living environments. Since I don’t know the specifics of the possible mold infestation that your asking about, it’s hard for me to give further advise. Plus, it would help to know what state you live in. New York, for example has some of the toughest guidelines regarding mold remediation.
