Contractor Complaints: Where to Start and What to Keep
Updated 2026-10-06
A home repair or renovation can go wrong in many ways. The work may be unfinished, the quality may be poor, the price may keep rising, or the contractor may stop answering calls after taking a deposit. These problems are stressful, especially when you have already paid money or moved out of your home for a project. The good news is that most contractor disputes follow a familiar sequence of steps.
This guide explains where to begin and what records to keep. Rules for contractor licensing, deposits, and complaints vary a great deal from state to state and sometimes from city to city, so use this page as a general starting point.
Start with the written contract
Find the contract, estimate, change orders, and any written promises the contractor made. Look for the scope of the work, the payment schedule, the start and finish dates, and any warranty. If the contract is missing or vague, write down what you remember and the date of each conversation.
Then gather your payment records. Keep canceled checks, bank statements, card receipts, and any receipts for materials you paid for directly. Photos of the work before, during, and after the project can also be important.
Check the contractor's license
Many states license certain contractors, and some cities have their own registration rules. A state licensing board usually keeps a public record of licensed contractors, including the license status and any disciplinary history. Search for the contractor's name and business name, and check whether the license covers the type of work done. A missing or expired license does not automatically mean the contract is void, but it can affect your options and the complaint process.
Ask the contractor for the license number and confirm it with the board yourself. Do not rely only on what appears on a truck, a business card, or a website.
Send a written demand
Before you file a formal complaint, consider sending a written demand. Describe the problem, quote the contract terms that apply, list what has been paid, and state what you want. You might ask the contractor to finish the work, correct defects, or refund part of the payment. Give a reasonable time to respond, and say what you will do if you do not hear back.
Send the letter in a way that gives you proof of delivery and keep a copy. A clear demand letter also helps a licensing board, a consumer office, or a judge understand what happened.
File with the right agencies
Several offices may accept complaints, depending on the problem:
- State licensing board. Many boards investigate contractors who break licensing rules, abandon projects, or take deposits without doing the work.
- State consumer protection office or attorney general. These offices often accept complaints about deceptive business practices and can help with mediation.
- Local building department. If the work did not pass inspection or lacks a permit, the local office may require corrections.
The USAGov consumer complaints page explains that you should usually try to resolve a problem with the company first, and it directs people to federal and state offices for help when that does not work. Include copies of your records, not originals, and keep the complaint number if you receive one.
Consider mediation or small claims
Some disputes can be settled through mediation, where a neutral person helps both sides discuss a fair outcome. Some courts also offer small claims procedures for smaller amounts. These procedures are designed for people who represent themselves, but they still require clear evidence and attention to the court's rules. Filing fees, deadlines, and limits differ by state and county, so check with the court clerk before you file.
When you go to small claims, bring your contract, payment records, photos, and written communications. If the work is defective, a written report from an independent inspector can be important evidence.
Watch for liens and deadlines
Some states allow contractors or suppliers to file a lien against a property if they are not paid. A lien can complicate a sale or refinance. If you receive a lien notice, read it carefully and speak with a lawyer about how to respond. Lien rules and deadlines are set by state law, and missing a deadline can limit your options.
Also note the dates of the contract, the payments, and each problem you reported. Some legal claims have time limits, and the clock may start earlier than you expect.
When a lawyer may help
A lawyer can be useful when the project cost is large, when the contractor took a substantial deposit, when there is structural damage, when a lien has been filed, or when the contractor refuses to respond. A lawyer can explain whether a breach of contract claim, a consumer protection claim, or a licensing complaint fits your facts.
For background on business and contract matters, see the business practice page and our guides. Ask how the lawyer charges and what the first consultation includes. Some construction and consumer lawyers offer a free or low-cost initial review, and others charge by the hour. Ask for a clear estimate of the next steps.
Questions to ask at the first consultation
- Is the contractor licensed for this work in my state?
- Does my contract require mediation or arbitration before a lawsuit?
- Is there a lien on my property, and what must I do?
- What is the deadline for a claim in my situation?
- Which complaint offices should I contact first?
- How do you charge, and what costs could I owe?
Frequently asked questions
Can I withhold the final payment?
Sometimes, but do so carefully. Your contract, state law, and the status of the work all matter. Talk to a lawyer before you stop paying, since withholding money can create its own problems.
Does a contractor have to be licensed?
It depends on the state and the type of work. Many states require a license for certain projects above a set scope. Check your state's board for the rules that apply.
Can I file a complaint if I already fired the contractor?
Yes. Complaints can cover work completed before termination, deposits taken, and unfinished projects. Include the timeline of events.
Will a complaint get my money back?
It may help, but no agency can guarantee repayment. Some disputes are resolved through mediation, and others require a court judgment.
