We're not medical professionals, and this site doesn't give health advice. The CDC says exposure to damp, moldy environments may cause a range of health effects, or none at all. Some people get a stuffy nose, coughing, wheezing or itchy eyes, and people with asthma, mold allergies or weakened immune systems can react more strongly (CDC: About Mold). If you have health concerns, talk to your doctor.

After a roof leak, burst pipe or flooded crawlspace, how to prevent mold in your Marin home, based on CDC and EPA guidance, with a step-by-step drying plan.
The CDC doesn't recommend routine mold testing. When testing helps, when it doesn't, and how to avoid paying for tests you don't need in your Marin home.
Many older Marin homes sit over damp crawlspaces. Why crawlspace mold happens in Marin, how to spot it, and fixes from vapor barriers to drainage.
"Black mold" isn't a scientific category, and color alone doesn't tell you the species or risk. The CDC advises removing any mold you find, whatever the type, and fixing the moisture that caused it.
Not always. The CDC doesn't recommend routine testing when mold is visible: just remove it and fix the moisture. Testing can be useful for hidden mold, real estate transactions, or checking that remediation worked.
The EPA says homeowners can often clean small areas on hard surfaces. For larger areas (about 10 square feet or more) the EPA points to its remediation guidance or professional help.
Coastal fog, shaded wooded lots, wet winters and older homes with crawlspaces all keep moisture high, and moisture is what mold needs.
It depends on your policy. Mold from a sudden covered water event is sometimes covered, often with limits. Mold from long-term leaks or humidity usually isn't. Check with your insurer.
