We have a problem with molds here as well. I've always had dust mite allergies. Mold is apparently a new one for me. But I'm reacting to something and this is a very old building. The basement, such as it is, floods on a regular basis and often stays full of water for some time. My other half and I have been wondering about how this is affecting both of us. We have no choice at the moment but to live here. No jobs and no other place to go for now. We're working on it though.
