Spray Foam Insulation License Requirements in Delaware
No exam-based contractor license; all construction contractors register with the state before starting work.
License Requirement
Licensing body: Delaware Department of Labor, Office of Contractor Registration
Delaware has no insulation-specific or general contractor exam license. Instead, all construction-services contractors — insulation installers included — must register with the Department of Labor's Office of Contractor Registration and obtain a business license from the Division of Revenue before beginning work.
SPFA Certification Relevance
SPFA (Spray Polyurethane Foam Alliance) certification is not a legal requirement here — no state licensing board makes it a condition of licensure. It remains a voluntary industry credential that some manufacturers require for warranty coverage and that SPFA's Professional Certification Program (PCP) references in federal Unified Facilities Guide Specifications (UFGS) for government contracts.
Bonding & Insurance Facts
Out-of-state (non-resident) contractors must post bonding or security — a surety bond, cash bond, or irrevocable letter of credit — with a simplified letter option available for contracts under $20,000. Delaware-resident contractors are not bond-required by the state registration itself.
