Maryland State Police are warning Carroll residents about a group of unlicensed home improvement contractors who often promise to do a "real good job" that is "very low in cost."
Police said the groups of fake contractors often target the elderly and residents of rural areas.
The groups often go door to door trying to convince homeowners that they need new driveways, repaired roofs, or a paint job on the house. They also peddle lightning rods, tools and travel trailers, police said.
