Question: We have black mold in our basement along the wall where water damage occurred 5 years ago. It has been there for some time and the basement smells terribly musty.
I have developed an allergic reaction in my eyes, and my father’s coughing has worsened.
We would like to have the black mold tested as soon as possible. Since the black mold is in the concrete wall, how would we extract samples?
Thank you for your help.
Answer: To get a sample of the black mold, please get clear scotch tape. Cut about 3 inches and stick the tape on the surface with mold. Peel the tape and stick it on a plastic bag (e.g., ziplock bag). Put the sample in an envelope and send it to us by mail or you can bring it to the lab. If the concrete surface is wet, use a cotton swab to get the sample since the mold may not stick to the tape. To use a swab, roll the tip of the swab several times on the surface with visible mold. Put the swab in a plastic bag and mail it to the lab.
If you suspect that you have a serious mold problem, I would suggest you get a professional to come and assess the extent of mold growth, determine the underlying cause(s) and then recommend the best way to remove the mold.
