Quick Answer

Document everything first. Try direct resolution. File with state licensing board (licensed contractors). File with BBB. Leave honest reviews. Use small claims court for amounts under $5K-$10K. Consult an attorney for larger disputes.

Before Filing Complaints

  1. Document everything – photos, videos, receipts, contracts, texts, emails
  2. Try direct resolution first – put concerns in writing, give reasonable time to respond
  3. Send a formal written complaint – certified mail, return receipt
  4. Review your contract – check for dispute resolution clauses
  5. Consult your state’s contractor laws – know your rights

State Licensing Board

If the contractor is licensed, the state board is your best first step:

  • What they can do: Investigate, discipline, suspend/revoke license, order restitution
  • What they can’t do: Force payment (usually), represent you in court
  • How to file: Online form or written complaint with documentation
  • What to include: Contract, photos, correspondence, timeline of events

License Complaints Get Attention

Contractors take licensing board complaints seriously because their livelihood depends on their license. Often, filing a complaint prompts settlement offers.

Better Business Bureau (BBB)

  • How it works: BBB contacts contractor, requests response, offers mediation
  • Success rate: About 70% of complaints are resolved
  • Impact: Unresolved complaints affect BBB rating, visible to future customers
  • Cost: Free to file

Small Claims Court

For monetary damages under your state’s limit (typically $5,000-$10,000):

  1. Check your state’s limit – varies from $2,500 to $25,000
  2. File at local courthouse – usually $30-$100 filing fee
  3. Serve the contractor – they must be notified of the suit
  4. Prepare your case – organize all documentation
  5. Attend the hearing – present your evidence to judge
  6. Collect if you win – may require additional steps

What to Bring to Small Claims

  • Signed contract
  • All change orders
  • Payment receipts/canceled checks
  • Photos: before, during, after
  • All written communications
  • Estimates from other contractors to fix problems
  • Timeline of events
  • Witness statements (if applicable)

Online Reviews

Honest reviews help other homeowners and often prompt contractor response:

  • Google Business Profile – most visible to searchers
  • Yelp – popular for service businesses
  • HomeAdvisor/Angi – contractor-specific platforms
  • Facebook – if contractor has business page

Keep Reviews Factual

Stick to facts, not emotions. “Contractor was 6 weeks late and didn’t return calls” is better than “worst contractor ever.” Factual reviews are legally protected; exaggerations can expose you to defamation claims.

When to Hire an Attorney

Consider legal representation when:

  • Damages exceed small claims limits
  • Contractor threatens legal action against you
  • Contract has complex legal terms
  • Structural damage or safety issues involved
  • Insurance claims are denied
  • Contractor files mechanics lien against your property

Protect Yourself for Next Time

  • Verify license and insurance before hiring
  • Get detailed written contracts
  • Use milestone-based payments
  • Never pay more than 10% upfront
  • Document everything from day one
  • Check references and reviews
