The Basement Health Association (BHA), formerly known as the National Association of Waterproofing & Structural Repair Contractors (NAWSRC), operates a nationally benchmarked certification program for Certified Egress Window Specialist®, Certified Waterproofing Specialist®, Certified Basement Air Quality Specialist®, and Certified Structural Repair Specialist®. BHA’s certification program is a comprehensive examination of work experience, textbook, and OSHA safety standards designed to qualify members of the profession as leaders of the below grade repair industry.
To qualify to become certified, contractors must be a member of the waterproofing industry for at least two years and their company must be a member of the association for at least one year.
After qualifying they are tested in various technical areas including safety and ethics. However, the certification process does not stop when they pass the written exam. To maintain their certification, they must obtain 15 hours of continuing education every two years and uphold the ethical standards of the association.
