How to choose window Companies in Pittsburgh

  • Ask for the contractor's Pennsylvania Home Improvement Contractor (HIC) registration number. It's required for most home improvement work over $500 and must appear on contracts and ads.
  • Get at least three written estimates that list materials, labor, timeline and cleanup.
  • Ask for proof of liability insurance and, if they have employees, workers' compensation coverage.
  • Check whether the job needs a permit in Pittsburgh and who will pull it. A good contractor handles this for you.
  • Never pay the full price up front. A reasonable deposit followed by payments tied to progress protects you.
