How this list is ordered

Verification first: Clinical Grade companies, then Advanced Verified, then Verified Pro. Clinical Grade companies with stronger Google reviews come first; Verified Pro companies are in alphabetical order. The sort menu changes only what you see.

Hire one company to test and a different one to remediate.

A company that tests your home and then quotes the cleanup earns more when it finds more mold. Listings marked “Testing and remediation” do both, so if you hire one of them to test, get the cleanup from someone else.
