Rankings can't be bought. ConcreteFinder scores each company with a Bayesian-adjusted Google rating, which weighs review volume so a 5.0 on three reviews does not outrank a 4.8 on three hundred. We then add small verification boosts for an active website, a listed phone number and real project photos. Across the GTA, 86% of rated concrete slab contractors clear 4.8★, so ranking gaps are meaningful. Positions update as new review data lands. Read our full methodology.
