8 Questions to Ask a Contractor Before You Hire in New Jersey
Hiring a contractor is one of the biggest decisions a homeowner makes. Done right, a renovation transforms your home. Done wrong — with the wrong contractor — it can cost you tens of thousands of dollars, months of your life, and leave you with a property that has unpermitted work or structural problems that show up at the worst possible time: when you’re trying to sell.
In Morris and Union County, NJ, there’s no shortage of contractors. But quality varies enormously. Here’s what to ask before you sign anything — and what the answers should sound like.
1. Are You Licensed in New Jersey?
New Jersey requires home improvement contractors to register with the state Division of Consumer Affairs under the Home Improvement Contractor (HIC) registration program. It’s not optional. Ask for their registration number and verify it at njconsumeraffairs.gov. Anyone who gives you a vague answer or gets defensive about this question is a red flag.
2. Do You Carry Liability Insurance and Workers’ Comp?
A legitimate contractor carries general liability insurance (to cover property damage) and workers’ compensation (to cover their crew if someone gets hurt on your property). Ask for a certificate of insurance — not just a yes. Call the insurance company to confirm it’s current. If a worker gets injured on your property and the contractor doesn’t have workers’ comp, you could be liable.
3. Will You Pull the Permits?
Any contractor who suggests skipping permits is doing you a disservice — or worse, setting you up for real problems. In towns like Chatham, Westfield, Madison, and Millburn, unpermitted work can delay or kill a home sale, require you to tear out and redo finished work, and may not meet current code. A good contractor handles the permit process as part of the job. That’s what it means to do the work right.
4. How Long Have You Been Working in This Area?
Local experience matters more than people realize. A contractor who’s been working in Morris and Union County understands local building departments, knows the inspectors, is familiar with the older home stock in towns like Summit, Short Hills, and Mendham, and has a track record you can actually verify. Ask for references from nearby towns — not just a general portfolio.
5. Who Will Be On-Site Daily?
Some contractors sell the job and then disappear, leaving a crew of subcontractors you’ve never met to do the actual work. Ask specifically: Will you (the owner or project manager) be on-site regularly? Who is my day-to-day contact? How do I reach someone if there’s an issue? Clear answers here are a good sign. Vague answers are not.
6. What Does Your Contract Include?
A real contract spells out the scope of work in detail, the payment schedule, the timeline, what’s included, what’s excluded, how change orders are handled, and what happens if something goes wrong. In NJ, contracts over $500 for home improvement work are required by law to be in writing. If someone offers to do your renovation on a handshake, walk away.
7. What’s Your Payment Schedule?
Be cautious of any contractor who asks for more than 10–15% upfront, or who asks for a large lump sum before work begins. A reasonable payment schedule ties payments to project milestones — materials ordered, rough work completed, final inspection passed. Paying too much upfront removes your leverage if problems arise. It’s also a common pattern in contractor scams targeting homeowners in Basking Ridge, Warren, Livingston, and throughout the region.
8. Can You Provide References from Similar Projects?
Ask for 2–3 references from projects similar in scope and location to yours. Then actually call them. Ask whether the project came in on budget, whether the timeline was accurate, how issues were handled, and whether they’d hire this contractor again. Most homeowners skip this step. Most homeowners who end up with contractor problems also skipped this step.
Red Flags to Watch For
Beyond these questions, here are patterns that should give you pause: pressure to decide immediately or lose the price; cash-only payment requirements; no physical business address; a quote that’s dramatically lower than everyone else (it usually means something is being left out or cut); and anyone who discourages you from getting a second opinion.
