Demand everything you paid, less the fair value of any work actually done. New York requires a written home improvement contract (GBL § 771) and requires advance payments to be held in escrow or covered by a bond (Lien Law § 71-a(4)), so a contractor who took a deposit and did no work is usually in breach of both. Send it to the legal entity name and registered address. One honest limit: a dispute about the quality of finished work usually needs an inspection first.
The deposit cleared, the start date slipped, the texts got shorter, and now the contractor is gone. This guide is the practical part: what to gather, how to work out the number, where to send the letter and what to do with each kind of reply. Why the law is on your side, the trust rules for deposits, the licensing rules and what you can recover beyond the refund, is set out in the attorney's guide to the law at Hochman Law PC.
The money trail is every payment with its date and method: checks, bank transfers, Zelle, Venmo, cash receipts. The promise trail is whatever shows what you were promised and when: the contract or estimate, the texts or emails about scope and start dates, and the last message where the contractor said they were coming back. Photograph the job as it stands today, room by room, before anyone else touches it.
Start with everything you paid. Subtract the fair value of any work that was actually done, judged honestly; if a second contractor will charge more than the original price to finish the job, write that figure down separately. A demand that already accounts for the work performed is much harder to wave away than one asking for every dollar back.
Letters to a nickname or a cell number get ignored. Look up the contractor's license record (in New York City, the Department of Consumer and Worker Protection's license search) and, if they operate as an LLC or corporation, the New York Department of State's business entity search. Use the legal business name and the registered address you find there, and also send a copy to the person who took your money.
The dates and amounts you paid, what was promised and when the work stopped. One line each on the law that applies: New York requires a written home improvement contract (GBL § 771) and requires advance payments to be held in escrow or covered by a bond (Lien Law § 71-a(4)). The exact refund figure from step 2, a specific deadline (ten to fourteen days is common), and what will follow if the deadline passes: a licensing complaint and a court claim.
Mail it by USPS Certified Mail with tracking to the registered address, and send the same letter by email or text if you have them. Keep the mailing receipt, the tracking printout and a copy of exactly what you sent. If the contractor later says they never got it, that receipt answers them.
A full refund or a firm payment schedule: get it in a short signed agreement before you accept, with dates and amounts. A partial offer: compare it with your number from step 2 and counter in writing. Silence after the deadline: file the licensing complaint, then a claim in court (the statute of limitations checker shows how long you have); small claims in New York City hears claims up to $10,000. One honest limit: this playbook is for money paid and work not done. A dispute about the quality of finished work usually needs an inspection first.
If you would rather have the letter drafted, signed and mailed by a New York attorney, that is the contractor demand letter, a flat fee.
To the registered address on their license record or Department of State filing, with a copy by email or text. A registered address is where legal mail is supposed to reach them.
A short, specific deadline, usually ten to fourteen days from the date they receive it. Name the date in the letter rather than writing a number of days.
It is not legally required, but it is the easiest way to prove the letter arrived. Keep the receipt and the tracking record with your copy of the letter.
Compare the offer with your own figure: what you paid minus the fair value of work done. If you accept, get the amount, the dates and a release in a short signed agreement first.
File a complaint with the licensing authority, then bring a claim in court. Your letter, the mailing receipt and the payment records are the core of that claim.
