If your home or property was built before 1978, renovations could disturb lead-based paint and create harmful lead dust. Wisconsin's Lead-Safe Renovation Rule protects kids from lead paint dust that can be created during renovation work. It requires contractors to be certified to safely work with lead paint.

You must hire a certified Lead-Safe Renovator if your home or property was built before 1978 and the project will:

  • Interior: Disturb more than 6 square feet of painted surface per room, or
  • Exterior: Disturb more than 20 square feet of painted surface, or
  • Involve a window replacement, or
  • Involve demolition.

These projects are regulated under Wisconsin's Lead-Safe Renovation Rule and must be done using lead-safe work practices.


  Step 2: Understand renovation vs. abatement

Not all lead-related work is the same. Here's the difference.

  Step 3: Hire the right certified contractor

Here's who you may need depending on your project:

If you need general remodeling, painting, or window replacement in pre-1978 buildings hire a Lead-Safe Renovator working for a Certified Lead Company.

If you need lead paint or soil removal or window replacement as part of a lead hazard order, hire a certified lead company with certified lead workers or lead supervisors.

Use your preferred search engine or method to find companies in your area that offer the type of work you’d like to have done. It’s always a good idea to seek bids from more than one company. Consider asking friends and neighbors who they recommend.

Make sure the person or company doing the work is:

  • Individually certified as a Lead-Safe Renovator, and
  • Employed by a certified lead company.
