Choosing a concrete contractor in New Jersey starts with checking that the business is legally allowed to do home improvement work. After that, compare the detail in the written estimates.
How do I find a good concrete contractor?
To find a good concrete contractor, ask for the New Jersey registration or license number and look it up with the Division of Consumer Affairs. Then ask for addresses of driveways or patios that have been through several winters and go and look at them. Compare two or three written estimates line by line.
Does a concrete contractor need to be licensed and insured in New Jersey?
Yes. A contractor doing home improvement work in New Jersey must be registered or licensed with the state. A 2024 law created the New Jersey State Board of Home Improvement and Home Elevation Contractors, within the Division of Consumer Affairs. The state requires commercial general liability insurance of at least $500,000 per occurrence, workers' compensation where the law applies, and a compliance bond of $10,000 to $50,000 depending on the size of the contracts. The Newark Concrete Company is licensed and insured. Ask any contractor for the number and the insurance certificate.
What should I ask a concrete contractor before hiring?
- What is your New Jersey registration or license number?
- Will the concrete be air-entrained, and at what strength?
- How thick is the slab and how deep is the stone base?
- What reinforcement is used and how is it held up off the ground?
- Where do the joints go and when are they cut?
- How does the concrete reach the back yard: truck, pump or buggy?
- Who pulls the permit and who calls New Jersey One Call?
- How is the slab cured and protected if the weather turns?
That list covers what should I ask a concrete contractor in this climate. The answers show quickly who plans for frost and salt.
What should a written estimate include?
A written estimate should state the area, thickness, base, concrete strength, air entrainment, reinforcement, joints, finish, tear-out and disposal, access method, permits, cleanup and price. In New Jersey a home improvement contract of $500 or more must be in writing and include the contractor's legal name, business address and registration number, a start date, a completion date, a description of the work and the total price.
How much deposit is normal?
A deposit of part of the price to book the job and buy materials is normal, with the rest tied to progress and completion. We found no state rule that sets a fixed limit on deposits for home improvement work. The Division of Consumer Affairs tells consumers it is customary not to pay for the whole project in advance. Keep a meaningful final payment back until the work is done.
A contractor wants 50 percent up front in cash with no contract. Should I agree?
No. Asking for 50 percent in cash with nothing in writing is the pattern consumer agencies warn about. Without a contract you have no start date, no description of the work and no proof of what you paid. New Jersey law requires a written contract at this size of job. Pay by check or card to the business name.
What are the red flags?
- No New Jersey registration or license number on the estimate or the truck.
- Cash only, or a check made out to a person.
- A price that is good only if you sign today.
- No mention of base, thickness, air entrainment or joints.
- Leftover concrete from another job offered at a discount.
- No insurance certificate when asked.
- Pressure to skip the permit for apron or sidewalk work.
What warranty should I expect?
Expect any warranty to be written down, with what it covers and for how long. Workmanship terms vary between contractors. Hairline shrinkage cracks and damage from deicing salt are commonly excluded. Ask to see the wording before you sign, and ask how a claim is made.
Can I cancel after signing?
Yes, for a short time. The Division of Consumer Affairs says you may cancel a home improvement contract for any reason before midnight of the third day after you receive a copy of it. Cancel in writing and keep proof of delivery.
I paid a deposit and the contractor stopped answering. What can I do?
If the contractor has stopped answering, send a written demand by email and certified mail with a deadline to start or refund. Then file a complaint with the New Jersey Division of Consumer Affairs at 1-800-242-5846. If you paid by card, ask the card company about a dispute. Small claims court is available for smaller sums. This is general information, not legal advice.
How do I know they have done stamped work before?
Ask for addresses of stamped jobs at least two winters old and go and see them. Someone who has really done stamped work before can show the stamp mats they own, explain how they keep the pattern straight, and tell you which sealer and grip additive they use. Photos alone prove little.
What if the crew hits a hidden water line?
If a crew hits a water line that was marked, or that they should have found, the repair is normally on the contractor. Public utilities are marked through New Jersey One Call. Private lines are not, so the contract should say who carries the risk for unmarked private pipes. Tell the contractor about sprinkler lines, yard drains and old oil tank piping.
Is a written estimate binding if they hit something unexpected?
A signed contract is binding for the work it describes. An estimate alone may not be. Buried rubble, an old foundation or a hidden tank are outside the described work, and a fair contract deals with them through a written change order with a price that you approve before the extra work is done. No signature should mean no extra charge.
