How do I verify a contractor's license in Westchester County?

Go to the Westchester County Department of Consumer Protection website and use the contractor license lookup tool. Enter the contractor's name or license number. All valid Westchester home improvement contractors are listed there. Also verify they carry current general liability and workers' compensation insurance by requesting certificates before signing any contract.

How many quotes should I get for a home improvement project in Westchester?

Get at least three written quotes. This gives you a market-rate baseline. If two quotes are within 15% of each other and one is 40% lower, the low bid is cutting something — usually quality of materials, experience, or insurance coverage.

How to Hire a Home Improvement Contractor in Westchester, NY (2026)

Westchester has hundreds of contractors, licensed and unlicensed. The difference matters enormously — both for the quality of work and your legal protection if something goes wrong. Here's exactly how to vet a contractor before signing anything.

Step 1: Verify the License

In Westchester County, all home improvement contractors must be registered with the Department of Consumer Protection. Check at consumer.westchestergov.com — search by contractor name or license number. An unlicensed contractor has no accountability to any oversight body, and you have almost no recourse if work is defective.

Step 2: Verify Insurance

Request certificates of insurance showing:

General liability insurance — covers property damage and injury on your property
Workers' compensation — if a worker is injured on your property without this, you could be liable

The certificates should name you (the homeowner) as an additional insured for the project period.

Step 3: Get Written Contracts

New York State law requires home improvement contracts to be in writing for projects over $500. Your contract should include:

Detailed written scope of work (not vague like "bathroom renovation")
Materials specification (brand, model, or grade)
Total price and payment schedule
Start date and estimated completion date
Process for change orders
Contractor's license number

Red flag: Any contractor who asks for full payment upfront. In New York, a deposit of 10-30% is reasonable. The rest should be tied to project milestones, with the final payment (10-15%) held until after the final walkthrough.

Step 4: Check References

Ask for 2-3 references from projects completed in the last 12 months — similar in scope to yours. Call them. Ask: Did they finish on schedule? Was the price accurate? Would you hire them again? Did they get the permit, and did the work pass inspection?

What to Watch Out For

Unusually low bids (often mean unlicensed, uninsured, or planning change orders)
Pressure to sign immediately or "lose the price"
Cash-only requirements
No physical business address
Reluctance to pull permits ("it'll save you money")
