Asphalt scammers are once again traveling through neighborhoods in Southeast Wisconsin, and the state Department of Agriculture, Trade and Consumer Protection is warning homeowners to beware and be aware.

Individuals are randomly knocking on doors and claiming they have extra asphalt from a job they just completed. Residents are quoted a price for a complete job, but once they pay, the work is either done so shabbily or the promised two-step process is never completed.

“The job is quickly and poorly done and the consumer is overcharged for the quality of the project. In some cases, only a base coat is applied and the promised top coat is skipped despite the consumer being charged for it,” the alert from the DATCP reads.

Because the crews move from one place to another, it’s difficult for law enforcement to catch up with them and even fewer options for homeowners to recoup their loss.

The DATCP advises residents to refuse the offer if a crew knocks on their door and to call police as soon as possible.
