What Happens When You Call
- Inspect first. A visual inspection with moisture readings decides where sampling is worth doing.
- Sample. Air samples run 5-10 minutes against a same-day outdoor baseline; surface samples identify species.

Pricing
What It Costs
Air testing runs $350 to $500 for one outdoor and two indoor samples; remediation is priced separately. See what mold removal costs.
Insurance
Insurance and Your Claim
Testing is usually paid privately. After a covered water loss, the lab report goes into the claim file with the rest of our documentation.
When Testing Is Worth It
- Buying an older Toronto house with flooding history or a musty basement.
- Symptoms at home but no visible mold.
- Someone with asthma, COPD or diagnosed mold sensitivity.
- Clearance after a large mold removal job, or a landlord-tenant or seller-buyer dispute.
If mold is already visible and the moisture source is known, testing rarely changes the plan.
