The owner

“We are a top tier contractor. Our equipment is clean, our trucks are clean, our uniforms are clean.”
Grant Schermitzler, owner

Grant started in 2022 with a drum sprayer, three 55-gallon barrels of sealer picked up from Menards, and a storage unit to keep them in. He brushed three or four driveways by hand that first summer, and by the end of it he had made money on it.

By the third season the rig was an 850-gallon sprayer with a nine-foot spray bar, a hot rubber melter and two F-250s, putting down about 1,500 gallons of sealer a week. One job that year was 19 driveways for a homeowners association, done in two days.

Recent Work

Sealcoating is the core of it. Asphalt and concrete both, so patching, sealing, striping and a concrete pour are priced and scheduled together. These are jobs from the 2026 season.
