How to document and escalate a contractor dispute

By Sherpa Desk Published Updated

The short answer

Create a dated file containing the contract, scope, changes, invoices, payments, permits, photos and communications. Tell the contractor in writing what is wrong, what resolution you request and when you need a response. If unresolved, use the relevant licensing authority, consumer office, insurer, lender or qualified local lawyer.

Editorial status: source-checked on 2026-08-22; not reviewed by a lawyer, licensing authority, engineer or trade professional. United States; notice, warranty, lien, arbitration and complaint rules vary. This is not legal advice.

Preserve and organize the record

Save the signed contract and attachments, bids, change orders, payment proof, permit records, warranties, product labels and messages. Photograph the whole area and details with date and location context. Keep original files and write a chronology that separates facts from opinions.

  • Chronology
  • Contract, scope and changes
  • Invoices and payment proof
  • Photos and independent reports
  • Permit and inspection records
  • Warranty notices and delivery proof

Request a remedy, then use the right channel

The FTC recommends first trying the contractor and, if calls fail, sending a certified letter with return receipt while keeping notes and copies. Quote the contract, state the evidence, request a remedy and give a response date.

Depending on the issue, options may include the licensing board, state attorney general or consumer office, building authority, insurer, lender, warranty provider, mediation or a lawyer. USA.gov maintains a state consumer-office directory. Safety issues and liens warrant prompt professional advice.
