cornerstone scores 24 of 45 on what its customers said, 0 of 25 on what it states about itself, and 30 of 30 on its website and record. Nothing here has been checked with a registry, an insurer or the WSIB. The middle pillar counts sentences this business wrote on its own website, which is why each one is worded as something it says rather than something anyone confirmed. The review pillar uses public Google review data republished here, and the ratings are set by reviewers, not by Countertop Installers.
