Spray Foam Insulation License Requirements in New Hampshire
No state general contractor license of any kind; New Hampshire licenses only a handful of specific trades, none of which is insulation.
License Requirement
Licensing body: No statewide general-contractor board
New Hampshire has no state general contractor license and no insulation-specific classification. The state licenses only a narrow set of trades — plumbers, electricians, and asbestos/lead abatement — none of which cover insulation. Regulation is local/municipal permitting, combined with mandatory business registration through the Secretary of State.
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
No statewide bonding or insurance mandate is tied to any license, since none exists for this trade. Workers' compensation is required if you have employees, but general liability insurance is not state-mandated.
