How this is built
Locations come from Overture Maps (open data), filtered to plumbing companies in the US and cleaned: duplicates merged, dead entries dropped, phone numbers normalized. Websites, opening hours and amenities are checked against each business's own site. We keep monthly snapshots, so the counts above are a point in time, not a running total — ask if you need an earlier one.
