The plumber market
Plumbing runs on the same small-crew, owner-operated model as electrical work, with licensing requirements that vary by state and keep national chains from dominating residential service. The owner is typically the one deciding which wholesaler to buy from and whether to adopt field-service software, since most shops don't have a separate purchasing role.
Frederick holds 0.1% of the 55,747 plumber businesses MapLeads tracks nationwide; within MD, Baltimore leads the vertical at 39.
