How we research companies in Fairfield

Our crawlers read what real customers already wrote in public, then apply one identical formula to every company. No surveys, no self-reported data, no paid placement.

We scan up to 8 public review sources

Google, Yelp, Facebook, BBB, Houzz, Angi, HomeAdvisor, Thumbtack, Nextdoor, HomeStars and industry-specific sites - not one platform's opinion.

Every company gets the same 0-100 score

Rating quality (30), review volume (20), source breadth (15), recency (12), consistency between sources (10), owner responsiveness (8) and data completeness (5).

Nobody can buy a position

There is no paid placement in this ranking. Companies can claim their profile to keep data current, but claiming never moves them up.

Rankings refresh continuously

Our crawlers re-scan businesses on a rolling schedule, so a company that starts collecting bad reviews drops - usually within days.
