How to Check a New Jersey Contractor Before You Sign: NJHIC Registration, Insurance, and Contracts
Almost every contractor horror story has the same opening chapter: the homeowner signed first and checked later. In New Jersey you have real tools to check first — a state registration system, insurance verification and contract rules written for your protection. Here is how to use them on any contractor, including us: ask us these same questions.
Step one: verify NJHIC registration and the business itself
New Jersey home improvement contractors are required to register with the state Division of Consumer Affairs and hold a Home Improvement Contractor registration, commonly shown as an NJHIC number in a format like 13VH followed by digits. Registration is not a skills test, but it does mean the business is on record, has met the state's registration requirements including insurance declarations, and can be looked up. Ask for the number, then verify it against the state's public records rather than taking a printed card at face value.
Check that the name and address on the registration match the name and address on your quote and contract — a mismatch deserves an explanation. A quick search of the business name for reviews across more than one platform, and a look at how complaints were handled rather than only the star average, rounds out the picture. A contractor who expects these questions will answer them with documents, not adjectives.
Step two: confirm insurance in a way that counts
Ask for a current certificate of insurance showing general liability coverage, and workers compensation coverage if the company has employees — and have it sent directly from the insurer or agent if the amount of work warrants it, rather than accepting an old photocopy. A certificate with lapsed dates, or one naming a different business, is not coverage for your project no matter how it is described in conversation.
Understand what insurance does and does not do: it protects against accidents and damage during the work, and it is also a rough signal of a business operating formally rather than casually. If a contractor suggests working without permits, without a written contract or strictly in cash, weigh what that informality would mean on the one day something goes wrong on your property.
Step three: read the contract like it is the project — because it is
New Jersey's home improvement rules expect written contracts for larger jobs, and a good contract earns its pages: a full scope of work, materials specified by type, a start and completion framework, a payment schedule tied to progress, a change-order process that requires your written approval before extra work is done, and the contractor's registration number and contact details. For home improvement contracts above a modest threshold, New Jersey consumers also have a three-business-day right to cancel after signing — check the current rule and make sure the cancellation notice is in your paperwork.
On payments, be wary of any schedule that front-loads most of the cost before work exists, and never pay in full before completion and any required final inspections. Hold the conversation, politely, at the document level: if a detail matters enough to discuss, it matters enough to write into the scope. Then request an estimate meeting at your home, bring your checklist, and hire the contractor whose paperwork is as solid as their pitch.
Questions homeowners ask
Is NJHIC registration the same as a licence?
In everyday conversation people say licence, but New Jersey's system for home improvement contractors is a registration with the Division of Consumer Affairs. What matters practically is that the number is real, current and matches the business on your contract — verify it in the state's records.
A contractor's quote is much lower than the others. Is that a red flag by itself?
Not automatically — but a dramatically lower price usually means a different scope, different materials or missing line items like permits, disposal or decking and sheathing allowances. Ask the contractor to walk you through their scope line by line against the other quotes before deciding.
What deposit is normal for a home improvement project?
Practices vary by project size and whether custom materials must be ordered, but the schedule should be staged against progress and milestones, and the bulk of the money should remain unpaid until the bulk of the work exists. If a deposit structure makes you uncomfortable, discuss it before signing — a reasonable contractor expects the question.
