Licensing in Delaware

Asbestos licensing in Delaware

Delaware requires asbestos abatement contractors, whether Class A or Class B, and professional service firms to hold a license, renewed each year, from the state Asbestos Office within the Division of Facilities Management. Supervisors, workers and project monitors need state certification after training from an approved provider. The state publishes a Certified Asbestos Vendors list on its open data portal where you can look up the license on record. Check the Asbestos Office's site for current requirements and which projects are covered.

Lead licensing in Delaware

Delaware requires individuals and firms that do lead-based paint work to be certified by the Division of Public Health. That includes contractors who disturb painted surfaces in homes, child care facilities and schools built before 1978, who must also follow lead-safe work practices. We did not find a public roster of certified firms, so ask for the certification on record. Check the division's site for current requirements.

Radon licensing in Delaware

Delaware does not have a state license or certification requirement for radon testing or mitigation. Delaware's Division of Public Health publishes only a voluntary list of local radon companies and says the state does not certify radon contractors. Many radon companies hold voluntary national credentials from NRPP or NRSB, so ask for proof of certification, and ask about any contractor licenses that apply to the work, such as electrical work. Check DPH's site for current information.
