Team Infinity Milwaukee, Appleton & Madison Contractors

Infinity Exteriors brings decades of contracting experience and teamwork in commercial and residential remodeling of all types. Our team is comprised of tradesmen who have acquired a wealth of experience from some of the largest and most respected companies in the country.

Josh & MJ Sparks Owners

Josh Sparks, the owner of Infinity Exteriors, got his start roofing shortly after graduating high school, leaving his “lucrative” position at McDonald’s to work with a good friend at a roofing company before going off to college in the fall. He started like everyone else; by cleaning up the grounds. As the summer went on, he worked his way up the ladder to become a shingler,’ and eventually foreman. Before leaving college, Josh started handing out flyers to do his own work to make some extra tuition money, and thus Infinity Exteriors was born.

After joining the Marine Corps, where he learned invaluable leadership skills, which he would bring to Infinity, Josh returned to his reserve post here in Milwaukee and started working hard at growing the business. His wife, MaryJean, came on board and business began booming.
