Trade certifications
Lawn Care Service Certifications Beyond Licensing
State and local licenses tell you whether a contractor can operate in lawn care service work, but they rarely show specialty depth. These certifications highlight safety training, manufacturer authorization, code knowledge, diagnostic skill, and third-party trade credentials homeowners can ask to verify before hiring.
