Three
generations.
One name.
Frank Mercer founded 11 Brothers in 1987 with a single pickup truck, a ladder, and a reputation for never missing a deadline. Nearly forty years later, his grandson Will runs the business — and the rule still holds.
We're a tight residential exteriors crew working homes across Sioux Falls and the surrounding Sioux Empire. Every job gets bid like our name is on the door. Because it is.
"If we wouldn't put our family in it, we won't build it for yours."
— Will Mercer, President
