Frequently asked questions
Is black mold more dangerous than other mold?
"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.
Do I need mold testing?
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.
Can I clean mold myself?
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.
Why is mold so common in Marin?
Coastal fog, shaded wooded lots, wet winters and older homes with crawlspaces all keep moisture high, and moisture is what mold needs.
Will insurance pay for mold removal?
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.
Do you do the remediation work?
No. We're a referral service that connects you with independent local providers. There's no cost to you to submit a request.
Can I remove mold myself?
The EPA suggests small areas under about 10 square feet can often be handled by homeowners following its guidance; larger areas or HVAC mold call for professionals.
Will bleach kill mold?
The EPA cautions against relying on biocides and emphasizes removing mold and fixing moisture; never mix bleach with ammonia.
Is black mold more dangerous?
The CDC recommends removing mold regardless of type; color doesn't identify species.
Why does mold keep coming back?
The moisture source wasn't fixed.
