The contractor market
General contractors and remodelers in this category are overwhelmingly small, owner-operated crews — one to a handful of employees, working residential jobs within a tight local radius. The owner is almost always the one answering the phone, bidding jobs, and deciding what to buy. Licensing and insurance requirements vary by state, which keeps the field fragmented rather than dominated by national players.
Gaithersburg holds 0.1% of the 528,890 contractor businesses MapLeads tracks nationwide; within MD, Baltimore leads the vertical at 443.
