Answer first: to choose a kitchen and bath remodeler on Long Island, confirm the company is licensed in your county and carries insurance, verify that license yourself through the county’s consumer affairs office, favor a design-build firm with a physical showroom and a verifiable portfolio, read reviews across more than one platform, and sign only a written, line-item contract that spells out who pulls the permits and what the warranty covers. The checklist below walks through every box to tick, how to verify a license in Nassau, Suffolk, and New York City, the red flags that should end a conversation, and the exact questions to ask at your first consultation.
The kitchen and bath remodeler checklist
Use this nine-point checklist before you sign anything. A remodeler worth hiring will pass every item without hesitation.
- Licensed and insured. The company should hold a current home improvement license for your jurisdiction and carry both general liability and workers’ compensation coverage. Ask for certificates of insurance, not promises.
- Verify the license yourself. Do not take a license number on faith. Look it up through the county (steps below); it takes two minutes and it is free.
- Design-build or general contractor. Decide whether you want one accountable team handling both design and construction or a separate designer and builder. See our design-build vs. general contractor guide.
- A physical showroom. You should be able to walk in, touch cabinetry, tile, and fixtures, and meet the people who will run your project. Browse our East Northport showroom before you commit.
- A real portfolio. Ask to see completed Long Island kitchens and baths, ideally projects similar in scope to yours. Our project portfolio is a good example of what to expect.
- Reviews across platforms. Cross-check Google, the Better Business Bureau, Houzz, and NKBA membership rather than trusting a single star rating.
- A written, line-item contract. Every material, allowance, and payment milestone belongs in writing. Vague lump sums hide surprises.
- Clear permit handling. The contract should state that the contractor pulls the required permits in the company’s name.
- A written warranty. Get the labor and materials warranty terms on paper before work begins.
How to verify a contractor’s license on Long Island
Answer first: verify a remodeler’s license free of charge through the consumer affairs office for the county where the work will happen. Each office keeps a public license lookup, and if a contractor is not listed, they are not licensed to work there.
Suffolk County
Search the Suffolk County Division of Consumer Affairs license database at ca.suffolkcountyny.gov/dcasearch, or call the office at (631) 853-4600. Operating a home improvement business in Suffolk County without a license is against the law, so an unlisted contractor is a hard stop.
Nassau County
Use the Nassau County Department of Consumer Affairs “Search Business With Valid Licenses” tool at nassaucountyny.gov, or call (516) 571-2600. Home improvement licensing in Nassau is mandated by county Administrative Code Section 21-11; if a business does not appear, it is not currently licensed.
New York City (co-ops, condos, and the boroughs)
Any contractor performing more than $200 of combined labor and materials in New York City needs a Home Improvement Contractor (HIC) license from the Department of Consumer and Worker Protection (DCWP). Look it up at nyc.gov/dcwp. The HIC license is held by the contracting business entity (a sole proprietor, partnership, corporation, or LLC), and a qualifying individual from that business must pass the DCWP Home Improvement exam (NYC DCWP). New York City also maintains a Home Improvement Business Trust Fund that can reimburse consumers for certain losses caused by a licensed contractor, so confirm the license shows an active status (NYC DCWP). City remodels also carry co-op and condo requirements: certificates of insurance, alteration agreements, and elevator reservations.
Design-build vs. hiring a general contractor
Answer first: design-build means one company owns both the design and the construction, so you have a single point of accountability; the traditional route splits those roles between a designer or architect and a separate general contractor. Design-build tends to reduce finger-pointing, keep the budget and the drawings aligned, and shorten the schedule, while the split model can suit homeowners who already have their own architect. We break down the tradeoffs in our full guide to design-build vs. a general contractor on Long Island.
Red flags to avoid
- Cash only, or a large cash deposit up front. Reputable remodelers accept traceable payments and tie deposits to milestones.
- “You won’t need a permit.” Structural, electrical, and plumbing work almost always requires one.
- They ask you to pull the permit in your name. This is often a sign the contractor is not properly licensed or insured for the job. Whoever holds the permit is the party responsible if the work fails inspection, so the licensed contractor should pull it in the company’s name (NYC Department of Buildings guidance; Angi).
- No physical showroom or verifiable address. A trailer and a cell phone are not a company you can hold accountable.
- Vague pricing or a one-line quote. A legitimate Long Island kitchen ranges widely (Sweeten reports roughly $23,500 to $102,500+ for a 120-square-foot rip-and-replace), so a credible remodeler prices line by line rather than guessing.
- High-pressure “sign today” tactics. A real proposal is still valid tomorrow.
Questions to ask at the consultation
- Are you licensed in my county, and what is your license number?
- Do you carry general liability and workers’ compensation insurance?
- Will you pull all required permits in your company’s name?
- Who is my dedicated project manager, and who is on site day to day?
- Is the design done in-house or subcontracted?
- What is the line-item estimate, and how are allowances handled?
- What is a realistic timeline? (Kitchens commonly run 2 to 4 months, driven by cabinet lead times of 4 to 16 weeks; bathroom construction often runs 2 to 4 weeks once materials are on site.)
- What does the warranty cover, and for how long?

Frequently Asked Questions
How do I check if a kitchen or bath remodeler is licensed on Long Island?
Look the company up free through the consumer affairs office for the county where the work will happen: Suffolk County Division of Consumer Affairs (ca.suffolkcountyny.gov/dcasearch or (631) 853-4600), the Nassau County Department of Consumer Affairs license search (nassaucountyny.gov or (516) 571-2600), and, for New York City work, the NYC Department of Consumer and Worker Protection HIC license lookup at nyc.gov/dcwp. If a contractor is not listed, they are not licensed to work there.
Do I legally need a licensed contractor for a remodel in Nassau or Suffolk?
Yes. Operating a home improvement business without a license is against the law in both Suffolk County and Nassau County (Nassau requires it under Administrative Code Section 21-11), and in New York City any job over $200 in combined labor and materials requires a Home Improvement Contractor license from DCWP. Hiring an unlicensed contractor can leave you without recourse if the work goes wrong.
Is design-build better than hiring a general contractor?
Design-build gives you one company accountable for both the design and the construction, which usually means fewer disputes, a budget that stays aligned with the drawings, and a shorter timeline. A separate designer plus a general contractor can work well if you already have your own architect. Our design-build vs. general contractor guide compares both routes for Long Island homeowners.
Should the homeowner or the contractor pull the building permit?
The licensed contractor should pull the permit in the company’s name. Whoever holds the permit is the party responsible if the work fails inspection, so a contractor who asks you to pull it yourself is a red flag that often signals they are not properly licensed or insured for the job (per NYC Department of Buildings guidance and consumer resources like Angi).
How much does a kitchen remodel cost on Long Island?
It varies widely with scope. Sweeten reports roughly $23,500 to $102,500+ for a 120-square-foot rip-and-replace kitchen on Long Island, and cabinetry is typically the single largest line item. A credible remodeler prices the job line by line rather than offering a one-number quote.
How long does a kitchen or bathroom remodel take?
Kitchens commonly run 2 to 4 months, with cabinet lead times of 4 to 16 weeks usually driving the schedule. Bathroom construction often runs about 2 to 4 weeks once all materials are on site. Ask any remodeler for a realistic, written timeline before you sign.
What questions should I ask before hiring a remodeler?
Ask for the license number and county, proof of general liability and workers’ compensation insurance, confirmation the contractor pulls permits in their own name, the name of your dedicated project manager, whether design is in-house, a line-item estimate with clear allowances, a realistic timeline, and the written warranty terms.
