You want to make sure you choose a mitigation and restoration company that is certified by the IICRC. That is the certifying body in the cleaning & restoration industry, and they require technicians to take the course work and pass exams proving their proficiency in the trade.
IICRC training and certification gives us the tools to build our cleaning, inspection, or restoration business with a plan for success through quality performance.
Technicians also must maintain their certifications by taking additional course each year. That ensures they learn any new techniques or can master new equipment that become available as advancement are made in the industry!
