How is this list of waterproofing contractors ranked?
+
Every list is ranked by proven rating: a business's Google rating weighted by the reviews behind it, so a perfect score from five reviews cannot outrank a near-perfect one from five hundred. No business pays to be listed or to move up. How the ranking works.
Ratings and review counts are Google's, as listed in October 2026. Phone numbers, websites and opening hours are the ones each business lists on Google. No business pays to be listed or to move up, and none is verified or endorsed by Agentize. How the ranking works.
