Chapter 37 Key Takeaways: Finding and Vetting Contractors

The Core Insight

A contractor's license is a floor, not a ceiling. It tells you they've cleared the minimum bar; the vetting process tells you whether they're actually good. Most contractor disasters follow skipped vetting steps.

Know Who You're Hiring

  • General contractors manage overall projects and hire subcontractors. Specialty contractors perform a specific trade (electrical, plumbing, HVAC, roofing).
  • Match the license to the trade: An HVAC license doesn't cover plumbing. A general contractor license doesn't cover electrical work in many states.
  • Verify every license yourself through your state's online database. This takes two minutes and reveals active status, license type, and disciplinary history.

Finding Qualified Candidates

  • Personal referrals from trusted people remain the most reliable source. Ask for specific experiences, not just names.
  • Supplier referrals (from plumbing supply houses, electrical supply, tile showrooms) often produce excellent recommendations — suppliers know which contractors pay their bills and do quality work.
  • Professional association directories (NARI, NRCA, PHCC, ACCA) provide a baseline of professionalism.
  • Get three bids for any project over $2,000. The goal is information, not just price comparison.

Insurance: This Is Your Problem

  • General liability insurance covers damage to your property and injuries to third parties caused by the contractor's work. Minimum acceptable: $500,000-$1,000,000 per occurrence for residential work.
  • Workers' compensation insurance protects you: if an uninsured worker is injured on your property, you may be liable for their medical expenses and lost wages.
  • Verify insurance directly with the insurer — not just from the contractor's certificate. Certificates can be forged; policies can lapse.
  • Sole proprietors may be exempt from workers' comp requirements. Ask how they handle this exposure and verify their answer.
  • Ask to be added as additional insured on the general liability policy.

The Interview

  • Conduct interviews in person, at your home, with the work scope visible.
  • Ask about: similar project experience, who will be on-site, permit process, subcontractor relationships, payment structure, warranty, and local references.
  • Call every reference. Ask the final question — "Would you hire them again without hesitation?" — and listen for the pause.

Red Flags: Recognize Them Early

  • Door-knockers after storms: get competitive bids from established local contractors before committing to anyone
  • Cash-only demands: no legitimate business reason; creates no paper trail
  • Large upfront deposits (over 30-50%): indicates financial problems or deposit-and-disappear risk
  • Reluctance to pull permits: creates legal, insurance, and resale problems
  • The "homeowner permit" suggestion: puts you on the legal hook for the work meeting code
  • No local references: concerning regardless of other factors
  • Price dramatically below competitors: ask why, specifically
  • Pressure tactics, artificial urgency: a professional contractor will wait while you make a thoughtful decision

Specialty Contractors

  • Electricians: Licensed electrician required for all circuit and panel work. Non-negotiable.
  • Plumbers: Licensed for all significant residential work. Permits and inspections matter.
  • HVAC: EPA Section 608 certification required for any work involving refrigerants. Watch for upselling — get a second opinion on any major system diagnosis.

Building Long-Term Relationships

  • Pay promptly. Be a prepared client. Communicate clearly and in writing. Give honest referrals.
  • Fair treatment of contractors produces better pricing, priority scheduling, and faster emergency response over time.
  • The contractor network you build over years is one of the most valuable assets of homeownership.
