How to vet a siding contractor in New Hampshire
New Hampshire’s Insurance Department explains that contractor licensing and insurance are separate checks. General contractors are not required to hold a state license, while certain specialty trades are regulated, so insurance evidence and the exact scope deserve careful attention.
- Ask the contractor for a certificate of liability insurance sent directly from the insurer or insurance agent whenever possible.
- Confirm that the business name, policy dates, coverage types, and limits fit the proposed siding scope, and ask about workers’ compensation coverage for any employees.
- Use the Electronic Workers Compensation Coverage Verification System to check coverage by employer and date.
- For work involving regulated specialty trades, confirm the appropriate trade credential separately; do not treat a general business claim as proof of specialty authorization.
What a fair siding quote should make clear
Comparable scopeCompare written scopes rather than a single total. A useful siding proposal identifies existing-cladding removal, disposal, moisture-management details, trim, repairs, materials, installation sequence, and cleanup.
Written responsibilitiesAsk who will obtain permits when the project requires them and how changed conditions behind existing siding will be documented and priced.
Project recordKeep the insurance certificate, endorsements, scope, change orders, and payment record with the signed proposal.
Red flags before you sign
