Score is Grade A Plumber's own 0–1,000 rating, computed from review quality and volume, recent activity, owner replies and a verified Michigan licence. Google ratings and counts are shown as reported by Google and are not this site's own rating. A green ✓ means we matched the company to a current Michigan plumbing licence; “verify” means it is not in our register extract yet — check the state record. A blank is not a claim that a company is unlicensed.
