## Why it ranks here

Blue Slate Group scores 75.9 out of 100, and most of its points come from the Google rating (40.5 of 44.4 possible) and claim accuracy (22.2 of 22.2 possible). It loses the most on years in business, 11.1 of 11.1 points, because no exact founding year was found on its website, so years in business counts 0. It earns no bonus points: we did not find published prices, 24/7 service shown in its Google hours or a written workmanship warranty with a stated term on its website.
