How to Hire a Mold Remediation Company You Can Trust
Finding mold in your home is stressful, and the last thing you need is a contractor who cuts corners. Here is how to tell a verified professional from a risky one, in plain terms.
Step 1
The three things to verify before you hire
A trustworthy mold remediation company can prove all three of these. If a company will not show you proof, treat that as your answer.
Licensed.
Confirm the company holds the mold license your state requires. Licensing rules vary by state, and some states require a separate license for assessment and for remediation.
Insured.
Ask for a current certificate of insurance, including general liability. This protects your home if something goes wrong during the work.
Rated.
Look for a real track record: recent reviews from real customers, not a handful of vague five-star posts.
Learn what the major certifications actually mean in our guide to mold certifications.
Step 2
Red flags to walk away from
Pressure to sign or pay in full before any inspection
No written scope of work or no containment plan
Cannot provide a license number or proof of insurance
Quotes a price over the phone without seeing the problem
Tells you to skip independent testing when the job is large
Step 3
Questions to ask before you commit
01
What license do you hold for mold work in this state?
02
Can you send a current certificate of insurance?
03
What does your remediation process include, step by step?
04
Do you recommend independent post-remediation testing?
05
Who handles the work, your own crew or subcontractors?

What “Verified” Means
A verified mold remediation company is one whose state license, insurance, and customer rating have each been independently confirmed, not self-reported. On Verified Remediation, professionals are ranked by verification level: licensed only, licensed and insured, or licensed, insured, and rated.
