How the points work
- Experience25
Years licensed or years registered with the state, whichever is longer.
- Insured25
Insurance on file with the state board that hasn't lapsed.
- Recent work25
City permits pulled in the last 12 months.
- Rating25
Public ratings, pulled toward the average when there are few. Shown only as “Highly rated”, and only where the rating matches the company by its phone or its own city.
- Points100
Numbers are compared with the other companies on this list, so the biggest firm can't run away with a signal. A company the data doesn't cover gets the list's middle score for that signal, not zero. A signal measured for fewer than 3 companies on the list is left out of its points.
