Common questions

Answers before you book.

When should I test for mold?
If you see visible growth, smell musty odors, or know there's been a water event. Also a good idea before closing on an older home with a basement or crawlspace.
How does the test work?
We collect air samples (and surface samples if visible growth exists) and send them to a certified lab. Results in 3-5 business days with species ID and counts.
Do you do remediation?
No — testing only, to stay unbiased. We refer trusted remediation contractors if needed.
