How to Handle Contractor Disputes

Documentation reduces a dispute from he-said-she-said to a paper trail. A timestamped photo of unfinished work is harder to argue than a verbal complaint. A signed bid that shows scope is harder to disagree with than a memory of what was discussed.

Start documenting at the start of the project, not when the dispute appears. Take photos at each milestone. Save every email and text. Use the project workspace timeline (or a shared folder if you do not have one) so both sides can see the same documentation.

A formal written complaint should include the date, the issue described in plain terms, the contract clause involved, the photographic evidence, and the requested resolution. Keep the tone professional. Hostile language makes resolution harder, not easier.

The goal of the written complaint is to give the contractor a chance to respond on the record. Most contractors who care about their reputation will respond constructively at this stage. Contractors who ignore a written complaint are signaling that they expect the dispute to escalate.

Bring a written agenda with three items: the issue, the supporting documentation, and your specific ask. The specific ask is the most important. Saying I want this fixed is hard to negotiate. Saying I want the entryway tile re-laid using the brand and tier specified in the bid, with no additional cost to me is something the contractor can either accept, reject, or counter.

Keep the meeting short. 30 minutes is enough. Longer meetings drift and rarely produce decisions.

Mediation makes sense when the direct conversation has stalled and both sides still want to avoid arbitration or court. A mediator is a neutral third party who facilitates conversation but does not make a binding decision. Mediation costs $200 to $500 in most areas, split between both sides.

Most mediated disputes resolve in a single 2 to 3 hour session. Mediation does not work when one side has decided to sue and is using mediation as a delay tactic. In that case, skip mediation and go to arbitration directly.

Arbitration is a binding alternative to court. Both sides present evidence to a neutral arbitrator (or a panel of three for larger disputes). The arbitrator's decision is enforceable in court but cannot be appealed on the merits. Most residential arbitrations under AAA Construction Industry Rules cost $1,500 to $5,000 in arbitrator fees plus filing costs, which is faster and cheaper than court.

Arbitration only applies if the contract has an arbitration clause. If your contract does not, the only path is small claims court (for disputes under your state's threshold, usually $5,000 to $15,000) or civil court for larger disputes.

Prevention is more effective than resolution. The three highest-leverage prevention patterns are a complete scope of work, a milestone-based payment schedule, and a written change order requirement. Together they remove about 80% of the conditions that produce disputes.

Marketplace platforms like ContractShield bake those patterns into every project: scope is captured in the work order, payments tie to milestones inside the workspace, and change orders require written approval before work continues. The result is fewer disputes overall, not better dispute handling.
