No state contractor licence. The NH Attorney General's own consumer alert states plainly: "In New Hampshire, contractors do not need to be licensed, and fraudsters may represent themselves to be reputable contractors in order to take homeowners' money." The AG advises consumers to ask each contractor for proof of insurance and to always have a written contract with a detailed scope of work, materials, total price and payment schedule before any work or payment. Note that NH does separately license some trades (e.g. electricians, plumbers/gas fitters) through the Office of Professional Licensure and Certification - garage door installation is not among them.
