Hiring a contractor in Rockland County is a town-by-town affair. There is no single countywide home improvement license: Clarkstown, Ramapo, Orangetown, Haverstraw and Stony Point each require contractors who work in their borders to hold a town-issued home improvement license, and each town keeps its own records, fees and complaint channels. New York State's Department of State licenses some trades and enforces rules on home improvement contracts, but the first call for a roofing or remodeling job is usually your town hall. Here is how to check a contractor out before signing anything.
1. Ask for the license number and the town it was issued in
A legitimate contractor working in Clarkstown should be able to produce a Clarkstown home improvement license number on request — and the same is true in Ramapo, Orangetown, Haverstraw town and Stony Point. If the contractor works across town lines, they may need a license in each town. Note that some villages (Nyack, Suffern, Spring Valley and others) layer their own requirements on top, so ask where the work site actually sits. Keep a copy of the license certificate with your job file — if a dispute ever reaches the town board or small claims court, the license number is how complaints get matched to a business.
2. Verify the license with the town clerk or licensing office
Call the town clerk's office or the town's building/licensing department and confirm three things: the license is current, it covers home improvement work, and the name on the license matches the name on your contract. In Clarkstown, licensing runs through the town clerk's office; Ramapo handles contractor licensing through its building department; Orangetown, Haverstraw and Stony Point have comparable offices. If a contractor says the license is "pending," treat the job as unlicensed until the town confirms otherwise.
3. Confirm insurance directly with the carrier
A town license does not prove insurance. Ask for a certificate of liability insurance and current workers' compensation coverage, then call the insurance agent listed on the certificate to confirm the policy is active. Request that your name and address be listed on a new certificate rather than accepting a photocopy — a genuine certificate issued for your job comes directly from the agent, and you should also ask to be notified if the policy lapses mid-project. Under New York workers' compensation law, most contractors with employees must carry coverage — and if an uninsured worker is hurt on your property, that exposure can land on you.
4. Check the contractor's complaint history
Rockland County's Department of Consumer Protection handles consumer complaints countywide, including disputes with home improvement contractors, per Rockland County government. Call or check the county site before hiring, and also ask the town licensing office whether complaints have been filed against the license. For larger disputes, the New York State Attorney General's consumer frauds bureau accepts complaints as well.
5. Get at least three written estimates
Comparing bids is not just about price. Three written estimates help you spot the outlier — the suspiciously low bid that often signals an unlicensed operator, a subcontractor switch, or material substitutions you didn't ask for. Make sure each estimate describes the same scope, materials and timeline.
6. Insist on a written contract — it's the law
New York's General Business Law requires home improvement contracts to be in writing and signed, with specific disclosures, per the state Department of State's consumer guidance. Your contract should list the contractor's license number, a start date and completion timeline, payment schedule, a detailed scope of work, and how change orders will be handled. Never rely on a handshake or a quote scribbled on a carbon pad.

7. Cap the deposit and stage the payments
Do not pay for the whole job up front. A common structure is a modest deposit — some town ordinances cap how much a licensed contractor may take before work begins, so ask your town's rule — followed by progress payments tied to completed milestones, with the final payment held until the work passes inspection. Pay by check or credit card rather than cash, and get a receipt for every payment. If a contractor pushes for a large cash deposit with a discount attached, walk away; the pattern shows up again and again in consumer complaints.
8. Confirm who pulls the permit
For most structural, electrical and plumbing work, the town building department requires a permit, and it should be pulled by the licensed contractor, not by you. If a contractor asks you to take out the permit as the "owner," that usually means they are unlicensed or trying to dodge town inspection. Permits protect you: they trigger the inspections that confirm the work meets code.
9. Check references from recent, local jobs
Ask for three references from jobs completed in the last year, ideally in your own town, and call them. Ask whether the job finished on time, whether the final bill matched the contract, and whether the contractor returned to fix punch-list items. Photos of finished work are nice; a phone conversation with a past customer is better. You can also search the contractor's business name in New York's Department of State corporation database to confirm the entity behind the contract actually exists and is in good standing.
10. Close the job properly
Before the final payment, walk the job with the contractor, confirm the town inspector has signed off on the permit, and collect lien waivers from the contractor and any subcontractors — documents confirming they've been paid and won't place a mechanic's lien on your home. Keep the contract, permits, receipts and warranty paperwork together; you'll want them when you sell.
If something goes wrong after the job, start with the town licensing office that issued the credential and the county Department of Consumer Protection. A complaint on the record is often what separates a contractor who fixes the problem from one who simply moves on to the next town.
