Before we moved to hell (Cleveland) we lived in Northern Ky across the river from Cincinnati. We had a new home built in 1998 by a regional developer (Drees). Our brick layers sucked - they left the site a mess and had to re-do the interior brick on the fireplace twice, talked like sailors and left bricks all over the yard (to be plowed under when they did the backfill).
About 6 months after we moved in a house was built across the street - the brick layers were hispanic and an older hispanic woman managed them. They were amazing - their work was excellent, they took not 1 extra minute for breaks and cleaned their equipment and stacked loose bricks EVERY night. They were also pleasant and didn’t cuss to high heaven like ours did.
I have no idea their legal/illegal status, but I sure hope this is not those guys.
You shouldn't worry. With 100's of thousand illegals in the greater Cincinnati area, the odds of it being them is very slight.
