What Detroit, MI is underserved in
The biggest opening in Detroit right now is ac repair: about 1,940 searches a month across Wayne County, and local companies pay $34.69 for each click. The three businesses at the top of Google Maps for it have a median of 54 reviews, which a newcomer can match with steady work. Too few searches here to build on: boat lift repair, crane rental, dock builder, electrical panel upgrade, ev charger installation, excavation contractor, grease trap cleaning, home addition, hurricane shutters, impact door installation, impact windows, land clearing, mobile home repair, pool installation, pool resurfacing, screen enclosure installation, screen enclosure repair, seawall repair and whole house repipe. Detroit is one of the biggest US cities, so scores here run high on sheer demand. Established companies spend heavily on ads and reviews, and the map pack is much harder to crack than in a mid-size town; a suburb or a single neighborhood is often the easier start. Big cities are left out of our national rankings for that reason.
