Fix the moisture source
Mold remediation is unlikely to succeed long-term unless the leak, humidity or water intrusion causing growth is corrected. Ask how the company will identify affected materials and prevent spores or debris from spreading during work.
Testing and remediation are different roles
For larger or disputed projects, independent assessment and post-remediation verification may help define the scope and evaluate completion. Ask what local rules and professional standards apply to your situation.
