How to Write a Demand Letter to a Contractor for Unfinished Work

Hiring a contractor to renovate your home is stressful enough, but it becomes a nightmare when they take your deposit and vanish, or leave the job half-finished.

If your contractor has ghosted you, stopped showing up, or refused to complete the work as outlined in your agreement, your first legal step is not to immediately hire an expensive attorney. Your first step is to send a formal Demand Letter.

Why a Demand Letter Works

A demand letter serves three critical purposes:

1. It creates a paper trail: If you eventually have to sue them in small claims court or file a complaint with the state licensing board, you need proof that you formally demanded completion or a refund.
2. It shows you are serious: Many contractors juggle too many jobs. A formal letter on professional letterhead signals that you understand your legal rights and will escalate the issue if ignored.
3. It sets a hard deadline: Phone calls and texts are easy to ignore. A certified letter with a strict 7-to-14 day deadline forces a response.

What to Include in Your Letter

To be legally effective, your letter must contain specific facts. Avoid getting overly emotional or insulting—keep it strictly business.

• The Original Agreement Details: State the date the contract was signed, the total agreed-upon price, and the exact scope of work.
• Money Paid to Date: Clearly list the amounts and dates of every payment you have made so far.
• The Breach of Contract: Factually state what work remains unfinished and when the contractor last showed up.
• Your Demand: Be extremely clear. Are you demanding they return to finish the work by a specific date, or are you firing them and demanding a refund of unearned money?
• The Consequence: State that if they fail to comply by your deadline, you will file a lawsuit, place a claim against their surety bond, and report them to the state contractor licensing board.

How to Send It

Always send your demand letter via USPS Certified Mail with a Return Receipt.

Contractors who are dodging you will often claim they "never got your letter." A certified mail receipt proves exactly when it was delivered and who signed for it, completely eliminating that excuse in court.
