South County mold work in older Chula Vista and National City stock often involves long-running leaks that finally got noticed.
Should I get a mold test before remediation?
If you can see it, you don't need a test to confirm it's there — money is better spent on remediation. Tests make sense when (a) someone in the home has confirmed mold-related health issues, (b) you need documentation for a real estate or legal matter, or (c) you want a third-party clearance after remediation. We refer testing to independent industrial hygienists so there is no conflict of interest.
Is mold dangerous?
It depends on the species, the spore concentration, and the person. For most healthy adults, household mold is more of a nuisance than a threat. For young children, the elderly, anyone with asthma or immune compromise, or anyone with prolonged exposure to high spore counts, it can drive real respiratory symptoms. The IICRC stance is that visible mold should be remediated regardless of species.
