The right questions up front separate a licensed local pro from someone who will take your money and leave the moisture behind.
Choosing who removes mold from your home matters as much as the removal itself, and a few checks up front are how you find a licensed local pro rather than someone who makes the problem worse.
Fix the water first, either way
Mold grows back if the moisture source stays. Any pro worth hiring will find and address the water problem, not just clean what you can see.

What licensing and certifications to look for
Requirements vary by state. Some states license mold assessors and remediation contractors; others do not, so check your state's rules through your local health or building department. Beyond any state license, look for industry certification such as the IICRC Applied Microbial Remediation Technician credential. These licenses and certifications belong to the contractor, so ask to see current, valid credentials before work starts.
Questions to ask before you hire
- 1 Will you give me a written scope of work? A clear document beats a verbal promise every time.
- 2 How will you find and fix the moisture source, not just the visible mold?
- 3 What is your containment plan so spores do not spread to clean areas?
- 4 Will there be independent post-remediation verification or clearance testing to confirm the job worked?
- 5 Can you show proof of current liability insurance and any required state license?
- 6 Can you share recent local references for similar jobs?
Keep the inspector and the remediator separate
For larger jobs, the company that tests for mold ideally should not be the same one that gets paid to remove it. An independent assessor removes the conflict of interest and gives you an unbiased read.
Red flags to walk away from
- Promises to permanently remove every trace of mold, which no honest pro can deliver
- Fear or pressure tactics to sign on the spot
- No written scope, or a price with no detail behind it
- No interest in the moisture source
- No license or proof of insurance when you ask
- Cash only, or a large deposit before any work
Get more than one estimate
Ask two or three pros to bid on the same written scope so you are comparing like for like. The lowest number is not automatically the right one, especially if it skips clearance testing or the moisture repair. Our residential and commercial cost estimators give you honest ranges so you know whether a bid is reasonable before you sign.
Offices that can help you check
To verify a license, look up your state rules, or raise a concern, your local health department, building department, and the regional EPA office are the right contacts. The who to call directory lists them by state.
