The estimate visit is your best shot at sorting things out, and it only lasts about half an hour. A painter walks your rooms, measures, talks paint, and hands you a number. Most homeowners spend that whole visit thinking about color. We get it — color is the fun part. But the five questions below are the ones that decide whether the job goes smoothly or turns into the kind of story you tell at dinner parties for years. Ask them before you sign anything, and listen less to how polished the answer sounds than to how specific it is.
1. "Are you registered with the state — and what's your number?"
This is the first question for a reason. In New Jersey, any business selling home improvements — painting is explicitly on the list — has to register with the Division of Consumer Affairs as a Home Improvement Contractor Business. The registration number starts with 13VH, and the law requires it to show up on contracts, ads, invoices, and work vehicles. A painter who does this work every day should be able to give you that number without hunting for it.
Don't just write it down. Run it. The state's free lookup takes a couple of minutes and tells you whether the registration is active and in the same business name that will appear on your contract. We have seen quotes where the number on the card belonged to a different company entirely — a friend's business, a former employer, a company that no longer exists. The name on the search result has to match the name on your contract, letter for letter.
What does a good answer sound like? Something like: "13VH followed by the digits, here's my card with it printed on it, and you can look it up tonight." What does a bad answer sound like? A shrug, a story about paperwork being at the shop, or the claim that painters don't need to register. They do. If the number doesn't check out, the rest of the conversation doesn't matter much, because the business isn't supposed to be selling home improvement work in New Jersey at all.
2. "Can I see your certificate of insurance — and is it current?"
Registration in New Jersey already requires commercial general liability insurance of at least $500,000 per occurrence, plus proof of workers' compensation coverage, according to the state's registration rules as summarized in this New Jersey contractor insurance guide. But registration is a filing with the state. The certificate of insurance in your hand is what proves coverage for your job, on your dates, under the right business name.
Ask for the certificate and actually read it. Three things to check: the company name matches the registered name from question one, the policy dates cover your job window, and workers' compensation is on there if the crew has employees. A ladder through a second-floor window is a property claim. A painter falling off that ladder is a much bigger problem, and if the company has no workers' comp, the injured worker's claim can come looking for the deepest nearby pocket — which may be yours.
Here's a detail that trips people up: a certificate proves a policy exists, not that you are covered by it. If your building or your own situation requires you to be listed as an additional insured, that takes an endorsement on the policy, not just your name typed onto the certificate. For a condo or a co-op, ask the building what it requires — many Hudson County buildings will hand you a checklist — and get the paperwork sorted before the start date, not the morning the crew arrives.
3. "What exactly will the written contract say?"
New Jersey requires a written contract for home improvement jobs costing $500 or more, and the county consumer affairs guidance spells out what belongs in it: the contractor's legal name and business address, a start date, a completion date, a description of the work, the total price, and the registration number. Your contract also has to tell you about your right to cancel within three business days of receiving a copy — a protection described in detail in this breakdown of New Jersey home improvement agreements.
So when the painter hands you the paperwork, read it like a scope sheet, not a formality. Does it name the rooms, the surfaces, and the number of coats? Does it say who supplies the paint, which product line, and what sheen goes where? Does it spell out the prep — patching, sanding, caulking, priming bare spots — or does it just say "paint living room"? Vague scope is where most painting disputes live. "We painted the living room" means one thing to you and another to a crew in a hurry, and the contract is the only place where your version gets written down.
Two more contract questions worth asking out loud. First, how are changes handled? A change order should be in writing, priced, and signed before the extra work starts — not remembered at the final invoice. Second, what's the payment schedule? A deposit plus progress payments tied to stages of the job is normal. Full payment up front is not, and neither is a final payment due before you've walked the finished rooms with the painter.
4. "How will you handle prep — and what about lead paint?"
If your house was built before 1978, this question carries real weight. Under the EPA's Renovation, Repair and Painting Rule, any firm paid to disturb paint in pre-1978 housing must be certified, and its workers must be trained in lead-safe work practices, as the EPA's contractor guidance explains. The rule covers painters by name. Minor repairs that disturb very little paint can fall outside it — six square feet or less per room inside, twenty square feet or less outside — but a full room repaint with scraping and sanding is not a minor repair.
Ask the painter directly: is your firm EPA-certified for this work, and will you follow lead-safe practices on my job? Then listen for specifics. Containment, careful scraping instead of dry-sanding a whole wall, daily cleanup, a final cleaning verification — those are the marks of a crew that has actually done this. A blank stare or a wave of the hand is not. And note what the rule does not cover: it doesn't apply to a homeowner doing their own work, so "you could just do it yourself" is not an answer to a question you asked a hired firm.
Even in a newer home, the prep question matters just as much. Ask what happens to the walls before the first coat goes on. Nail pops get screwed and spackled, not just painted over. Water stains get a stain-blocking primer, not a second coat of the same white. Bare patches get primed so the finish doesn't flash. A good painter will walk you through this room by room, because prep is most of the job — anyone can roll color onto a wall, and the difference between a two-year paint job and a ten-year one is almost entirely what happened before the color went on.
And while you're on the subject of paint itself, ask which product line they plan to use and why. There's a real difference between a builder-grade gallon and a premium Benjamin Moore or Sherwin-Williams product in hide, washability, and how it touches up two years later. You don't need the most expensive can on the shelf in every room, but you should know what you're paying for, and the answer should reference your rooms — a hallway that takes abuse from kids and dogs is not the same call as a guest bedroom nobody enters.
5. "Who's actually doing the work — and what happens if something goes wrong?"
The person at your kitchen table with the samples is not always the person on the ladder on Tuesday. Ask who will be in your house: the company's own employees, a regular crew, or subcontractors brought in for the week? None of those answers is automatically bad, but each one changes what you should check next. If subs are involved, ask whether they carry their own insurance and registration — under New Jersey's current rules, a subcontractor can't just ride along under someone else's registration.
References fit here too, and there's a better way to ask for them than "do you have references?" Ask for the last three jobs like yours, in towns near you, and whether you can drive past one. A painter with a solid book of work in, say, Montclair colonials or Jersey City condos will have recent addresses ready. A painter who can only offer a cousin's apartment from three years ago is telling you something, even if he doesn't mean to.
Then the warranty question, asked plainly: "If a wall peels or a ceiling cracks in a year, what do you do?" Get the answer in the contract, with a length of time and a process — who to call, how fast they come back, what's covered and what isn't. Paint manufacturers warranty their product; your painter warranties the workmanship. Peeling caused by a prep failure is a workmanship problem, and a painter who won't put a warranty in writing is a painter who has already decided how that conversation will go.
The short version to take to the estimate
You don't have to memorize the statutes. You just have to ask the five questions and pay attention to whether the answers are specific, documented, and in writing. Registered with a verifiable 13VH number. Insured, with a current certificate in the right name. A written contract that names the rooms, the prep, the paint, the dates, and the price. A lead-safe plan if your home predates 1978. A named crew and a written warranty.
If a painter answers all five cleanly, the price conversation gets a lot simpler — you can compare his number against our guide to what a house paint job actually costs in New Jersey knowing you're comparing real businesses doing real work. And if a painter dodges more than one of them, you've already learned the most useful thing the estimate was going to teach you. We wrote about the signs a NJ painter is cutting corners for exactly that moment — when the job looks fine on the surface and the paperwork tells a different story.
In the Hoboken area and across Jersey City and Hudson County, you don't have to look far for painters who answer these questions without flinching. Ask them anyway. The good ones like being asked — it's the fastest way for them to show you the difference between their crew and the guy who just hopes you never check.
