How we rank
Each plumber gets a review-weighted rating: businesses with few reviews are pulled toward the Portland average of 4.8 stars, so a perfect score from a handful of reviews can't outrank a strong score from hundreds. No business pays for its position. Full method.
Questions

About every 30 days. This version uses data collected on October 20, 2026.
Why isn't a plumber I know listed?
