How to File a Complaint Against a Contractor

Before you file anything, build a complete record. Gather the signed contract, every invoice and proof of payment, all change orders, and a timeline of what was promised versus what happened. Take clear, dated photos of the defective or incomplete work from multiple angles. Save every text, email, and voicemail with the contractor.

Documentation is the foundation of any complaint. Licensing boards, surety companies, and courts decide based on evidence, not on which party is more frustrated. The stronger your record, the more credible your complaint and the faster it tends to resolve. If your project ran through a platform that stored the contract, change orders, and payment history in one place, that record is already assembled for you.

Most jurisdictions and most contracts expect you to give the contractor a reasonable opportunity to fix the problem before you escalate. Send a written notice, by email and ideally by certified mail, that clearly describes the defect or unfinished work, references the relevant part of the contract, and states what you want done and by when. Keep the tone factual.

This step matters for two reasons. First, many issues are resolved here, because a contractor who wants to protect their license and reputation will often return to correct legitimate problems. Second, if the dispute does escalate, showing that you gave written notice and a fair chance to cure strengthens your position with the licensing board or court. Skipping this step can weaken an otherwise valid complaint.

If written notice does not resolve the issue, the next step for licensed-trade and contractor work is usually the state contractor licensing board. Most states have an online complaint process. You submit your documentation, describe the problem, and the board reviews whether the contractor violated licensing rules or building standards. The board can investigate, mediate, order corrective action, or in serious cases discipline the license.

The licensing board is often the most effective non-court route because a contractor's license is their livelihood. A pending board complaint creates real pressure to resolve. Be precise and factual in your filing, attach your evidence, and follow the board's process. If the contractor was unlicensed, the board may have a separate process for unlicensed-activity complaints, which is itself a violation in most states.

If the contractor was bonded, you may be able to file a claim against their surety bond for losses from non-performance or contract violations. The bond details are on the contract or available through the licensing board. The surety investigates and, if the claim is valid, pays up to the bond limit, then pursues the contractor to recover.

If you paid by credit card, you may also be able to dispute the charge with your card issuer for work not performed or materially defective, within the issuer's time limits. These avenues can recover money faster than court. They work best when your documentation is clear and when you have already given written notice, since both the surety and the card issuer will look for evidence that you tried to resolve the issue directly.

If other routes do not make you whole, court is the final step. For amounts within your state's small claims limit, small claims court is designed to be navigated without a lawyer and handles many contractor disputes. For larger amounts, you may need civil court and an attorney. Either way, your documentation and your record of written notice carry the case.

Before filing, weigh the cost and time against the amount in dispute, and consider whether a settlement is achievable. Many contractors settle once a court filing is imminent. If you win a judgment, collecting it is a separate effort, which is another reason the earlier steps, especially bonding and milestone payments, matter. Limiting your exposure upfront is far easier than recovering money after the fact.

The best complaint is the one you never have to file. Most contractor disputes trace back to a few avoidable causes: paying too much upfront, hiring without verifying license and insurance, and agreeing to changes verbally. Tie payments to completed milestones, confirm credentials before signing, and put every change in writing.

A managed marketplace builds these protections into the workflow. On ContractShield, contractors are verified before they can bid, payments are structured around milestones rather than large deposits, and the contract, change orders, and communication live in one record. A public review system also gives contractors a long-term incentive to resolve issues rather than walk away. The result is fewer disputes, and when one does arise, a complete record ready to support your case.
