Application Information

Getting Certified to Work with Lead Based Paint​

Training and certification are required for professionals who offer or conduct regulated lead-based paint activities in pre-1978 housing and child-occupied facilities. These activities include:

• Abatement of Lead Hazards​
  
• Lead Testing, Inspection, and Risk Assessment
• Most paint-disturbing renovation work (for example, replacing windows, scraping paint prior to re-painting)
• Post renovation and post-abatement clearance (including dust wipe sampling to measure lead dust left behind)

By getting certified and working safely, you protect your own and others' health, and show professional responsibility. For more information about certification, visit the Wisconsin Department of Health Services​ website.​​
