The Department of Health Services (DHS) does not endorse the companies on these lists. Some companies qualify to offer lead services but have chosen not to be listed publicly. We recommend that consumers do the following when choosing a company:

  • Check the certification status of the company and its employees or subcontractors. Both company and individual certifications are required in Wisconsin.
  • Seek bids from multiple companies when possible.
  • Conduct reference checks.
  • Have a written contract for services before engaging any company.

Types of Certified Lead Companies

Lead-Safe Renovation

A lead-safe renovation company is qualified to work lead-safe when performing renovation, repair, painting, or remodeling work that disturbs paint in residential and child-occupied facilities built before 1978. Window replacement, siding removal, and interior remodeling are just a few examples of work a that may only be conducted by a certified lead-safe renovation company. 

A certified lead-safe renovator must be assigned to the job, and all individuals involved must have received on-the-job training in lead-safe work practices.

Lead Investigation

These companies are qualified to conduct some or all of these activities: inspect for lead-based paint, identify lead hazards through a risk assessment, conduct hazard screens to determine whether a risk assessment is warranted, or conduct post-abatement or renovation clearance. They may also conduct lead-free and lead-safe property inspections.

Depending on the nature of the investigation, individuals performing this type of work must be certified as a lead risk assessor, hazard investigator, inspector, or sampling technician.

Lead Abatement

A certified lead abatement company is qualified to control and eliminate lead-based paint hazards identified through a risk assessment, and every abatement job must pass a third-party clearance before it is considered complete.

Lead abatement companies may work on properties under orders, or properties receiving federal or state funding, to reduce or eliminate lead hazards.

There must be at least one certified lead abatement supervisor on site while abatement work is ongoing, and all individuals involved must be, at a minimum, certified as lead abatement workers.
