Those are Irish Travelers. They specialize in just what you said. I recall one stopping by my parents place while I was there.

He asked about paving their long driveway. I knew who he was immediately.

They typically drive brand new high end pickups and are also typically handsome. Yet they did come from Ireland and are not genetically related to the Roma.

And most of them live in Murphy Village SC and have either Murphy or Riley as a last name. They spread out from there all over the country to do scam jobs like repaving driveways and roofing jobs.
