A dated complaint letter is your written demand. Ask the contractor to repair defects, finish the job, or return money you already paid. It's not a lawsuit.

They promised a crew after your last call, then nobody showed up on the day they named. Have you put that promise on paper?

Keep copies, because the same letter later becomes the packet you attach to a state contractor board filing or a consumer agency complaint. It also belongs in a small-claims court case. Phone calls do not travel well.

Thing is, the Federal Trade Commission tells homeowners to follow those conversations with a letter sent by certified mail, since disputes often sit still until a deadline exists.

This is practical writing help for U.S. consumers, not legal advice. Your contract and your state's contractor rules decide what you can actually require.

Re: Written complaint for work at [property address], contract dated [date], [contract number if any]

Dear [Name]:

I am writing about the home improvement work at [property address] under our contract dated [date]. I have paid $[amount] so far.

The following problems remain unfinished or defective:

1. [Issue, room or location, and the date I first noticed it]
2. [Issue]
3. [Issue]

These items do not match the work described in our contract. I request that you correct them at no extra charge by [date, often 14 days after expected receipt], or that you refund $[amount] for the incomplete or defective portion.

Please respond in writing by [date]. If I do not hear from you, I intend to file complaints with my state contractor licensing board and other consumer agencies, and I will consider other options available under our contract and state law.

Sincerely,
[Your signature]
[Your printed name]

Enclosures: contract, photos, invoices, prior emails

Send the original by certified mail, return receipt requested, and keep a copy of the letter with the photos attached to that copy. Insults in the last paragraph make you easier to ignore.

What actually controls a contractor dispute

Reviewers reach for the signed contract before they listen to anyone's story. Work scope, materials, payment dates, and the completion date on those pages beat a handshake you cannot prove.

Your state's rules sit under that contract, and depending on where the house sits you might get a licensing board that will look at photos and issue a citation, or a thinner process, or extra rules if the salesperson spoke a language other than English, which the FTC notes may entitle you to a contract in that language depending on where you live and what you bought, and a one-page template will not capture any of that local detail.

There's no single federal refund statute for every botched kitchen, and the Better Business Bureau is not a government agency that replaces a contract or a state board. A BBB file can still matter if the company cares about its public grade.

Licensing boards can investigate licensed firms and issue citations. Unlicensed operators are a different problem. The path is usually a consumer-protection office, or the police if money was taken and no work followed.

Don't assume a multi-year implied warranty unless your paperwork or your state statute actually grants one. Lengths vary, and some jobs get treated as services, not product sales.

FTC home-improvement guidance says not to make the final payment until the work is done and you are satisfied, so the payment schedule is often the leverage you still have, and New York's consumer office also warns people not to pay the full price up front and to be wary of unsolicited door-to-door pitches.

If you already paid in full, send the letter anyway. You just have less day-to-day pressure.

How to write and send the letter

Write from the file, not from memory.

1. Gather the file first: contract, change orders, invoices, proof of payment, dated photos, videos, texts, and emails.
2. Write each defect so a stranger could find it in the house. "Kitchen sink leaks at the supply line" is usable. "Horrible job" is not.
3. Ask for a repair by a date, a refund of a stated amount, or both.
4. Put a response deadline on it. Two weeks after delivery is a common window. Same-day demands look theatrical.
5. Send it certified mail with return receipt. Write the tracking number on your copy.
6. Email a PDF only as a courtesy copy. The certified piece is the one that proves delivery.

Re: Failure to complete [project] at [property address] by [agreed completion date], contract dated [date]

Dear [Name]:

Our contract dated [date] required completion by [agreed date]. I have paid $[amount]. The following items are still unfinished: [list each item].

This delay has [concrete cost or impact if you have one, such as a temporary housing bill or a failed inspection]. I request that you complete the remaining work by [new date] or refund $[amount] for the unfinished portion.

Please confirm in writing by [date]. If I do not receive a written response, I will file with my state contractor licensing board and other consumer agencies.

Sincerely,

If they took a deposit and disappeared, say the last day anyone was on site, include the amount you paid, attach the cancelled check or card statement, and then file with the agencies instead of waiting around for a courtesy call that is not coming, because that call is not coming. Don't wait out a second polite month.

If you signed at home, check the Cooling-Off Rule

The FTC Cooling-Off Rule is a short right to cancel certain sales. A complaint letter asks someone to fix work already done.

Purchases of $25 or more made at your home can fall under it, as can sales of $130 or more at a temporary spot such as a hotel, fair, or convention center, and the seller should give you cancellation forms.

You usually have until midnight of the third business day after the contract date, and the envelope must be postmarked in that window. Certified mail is the clean way to prove it.

Turns out a lot of remodels never qualify, because sales closed at the contractor's regular office often fall outside the rule and many phone and online orders fall outside it too.

Don't count on three days if nobody sat in your house to close the deal, and if the sale happened in your living room, read the rule before you treat the contract as locked.

Sign and date a cancellation letter. Mail it even if the packet has no forms. If they ignore a cancellation that fits the rule, report it to the FTC and to your state attorney general's consumer division.

Where to send the complaint after the letter

Give the contractor the deadline first. Escalate next with the same exhibits.

Match the forum to the facts: a licensing board looks at license law, small claims looks at the money, and the FTC looks at patterns and scams.

Example: filing with California's contractor board

The Contractors State License Board in California publishes a real consumer complaint path. Other states have their own boards. Look up yours by name plus "contractor license complaint."

CSLB may ask you for more documents if the first packet is thin. Not every file gets a site visit.

Citations may include civil penalties of up to $30,000 and orders of correction that require the contractor to repair the work or pay you so you can hire someone else, and the board also runs mandatory and voluntary arbitration programs.

CSLB wants to hear the result if you later win in small claims or collect on a license bond. Check your own board before you borrow California's forms. Other states set their own dollar figures and timelines.

Documents worth attaching

To be honest, the letter is only half the file. The attachments do the real work.

• Signed contract, addenda, and change orders
• Invoices, receipts, cancelled checks, or card statements
• Dated photos and a short video of leaks, gaps, or unfinished rooms
• A log of calls with dates
• The contractor's license number, if you have it
• A copy of the certified-mail receipt once you have it

Print one set and staple it. That stack travels to every agency you contact later.

Walk it to the post office this week, clip on the three clearest photos of the worst defect, then write the deadline on your calendar the day the return receipt comes back.
