How to Choose a Remodeling Contractor in NJ (Without Getting Burned)
Verify NJ HIC registration, ask for proof of liability and workers' comp insurance directly from the agent, request three local references with photos of 3+ year-old projects, and never pay more than 1/3 as a deposit (NJ law caps it). Get a detailed written scope with allowances, payment schedule tied to milestones, and a written change-order process before signing.
Verify before you meet
Check the contractor's NJ Home Improvement Contractor (HIC) registration at njconsumeraffairs.gov. Look up Better Business Bureau, Google, and Houzz reviews for patterns (one bad review is normal; the same complaint repeated is not). Search the company name + 'lawsuit' or 'mechanic's lien'.
Insurance — the right way to verify
Ask for the Certificate of Insurance (COI) to be sent directly from the insurance agent or broker, listing you as a certificate holder. Don't accept a PDF the contractor emails — it can be edited or expired. Required: general liability ($1M minimum) and workers' compensation.
Questions to ask every contractor
1) Who is on-site daily — owner, foreman, or subs? 2) How many active projects do you run at once? 3) What's your typical timeline for a project this size? 4) How do change orders work — written, signed, priced before starting? 5) Do you handle permits and inspections? 6) What's your warranty (1 year is minimum; 2+ is excellent)? 7) Can I see a current project in progress?
Red flags to walk away from
Demands more than 1/3 deposit (illegal in NJ). Pressure to sign immediately. No physical office or vehicle signage. Cash-only or unwillingness to put things in writing. Bid more than 20% below others (missing scope or unlicensed labor). Refuses to pull permits ('I can do it without permits to save you money'). Vague timeline.
Contract must-haves
Detailed scope with brand/model for major items. Allowance amounts clearly listed (and labeled as allowances). Payment schedule tied to milestones, not calendar dates. Start and substantial completion dates. Written change-order process. Lien waivers from subs at each payment. Warranty terms.
References — what to actually ask
Did they finish on time? Did the final cost match the bid (within reason)? How were change orders handled? How was their cleanup? Would you hire them again? Can I drive by and see the work?
Frequently asked
Is a low bid usually a bad sign?
Bids more than 15–20% below competitors typically indicate missing scope, lower-grade materials, or unlicensed labor. Compare bids line-by-line, not just bottom-line totals.
How much deposit can a NJ contractor legally ask for?
NJ caps deposits at 1/3 of the contract price for home improvement work. Anything more is illegal and a major red flag.
Should I hire the cheapest contractor?
No. Hire the contractor with the most thorough written scope, verifiable references on similar projects, valid insurance, and a fair (not lowest) price. The cost of fixing bad work is always higher than the savings from a low bid.
How do I check if a NJ contractor is licensed?
Search the contractor's HIC number or company name at njconsumeraffairs.gov. The lookup shows registration status, expiration date, and any complaints.
Do I need a written contract for small jobs?
NJ law requires a written contract for any home improvement project over $500. Below that, it's still strongly recommended.
