Asbestos: Check Asbestos Company Certification
Where to start
We recommend using your favorite internet search tool 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.
When you've found a company
It’s a good idea to have a written contract for services. Before you sign it or pay any money, make sure any companies named in the contract are on our current certified company list.
The list is a Microsoft Excel spreadsheet. Email us at DHSAsbestosLead@dhs.wisconsin.gov to request a different file format (for example, PDF).

We update the list monthly.
There are two kinds of company certification.
Asbestos company
For companies that perform, direct, or advertise asbestos work, including:
- Asbestos abatement, removal, or disturbance;
- Air sampling, inspection and bulk sampling, and asbestos management.
Exterior asbestos company
For companies that only work outside of buildings or structures on materials with asbestos that don’t crumble (non-friable) and stay that way during the project
When the work starts
Companies need to use workers with the right kind of training and certification for the job. Anybody who is certified must have proof of certification available while doing work that requires it, so you can ask to see this.
Removal, abatement, or disturbance – interior or exterior, friable or non-friable
People doing this work must have asbestos worker or asbestos supervisor certification. At least one abatement supervisor must be on site to oversee the project.
Removal, abatement or disturbance – exterior only, non-friable only
People doing this work must have exterior worker or exterior supervisor certification. At least one exterior supervisor must be on site to oversee the project.
Inspection, bulk sampling, and asbestos management
People doing asbestos inspection and sampling work must have asbestos inspector certification. Note: Exterior asbestos supervisors may sample non-friable materials on the exterior of buildings.
Only certified asbestos management planners may create asbestos management plans. Only certified asbestos project designers may write plans for and design asbestos projects.
Air sampling
A person who samples air for asbestos must have asbestos supervisor certification.
