Commercial Properties
Sealcoating and concrete, repair, striping, catch basins and paving, on a maintenance schedule rather than one job at a time. We plow the same lots through the winter.
Commercial services
Residential Driveways
Driveway sealcoating held to the same standard as our commercial lots: cleaned and prepped first, cracks filled hot, edges cut in by hand.
Driveway sealcoatingWhat we do
Everything a Lot Needs, From One Company
Sealcoating and concrete are the core of it. The rest is the work most sealcoating companies send somewhere else.

Sealcoating
We bring gray, faded blacktop back to a deep, even black with Pitch Black asphalt emulsion, no coal tar.

Crack Filling
We fill cracks with hot rubber at 400 degrees, so the filler bonds to the crack and stays flexible through winter.

Asphalt Repair
We cut out potholes, alligator cracking and sunken areas and rebuild them full-depth.

Catch Basin Repair
We rebuild the collar around a sunken storm grate and bring it back to grade, removing the dip and the trip hazard.

Striping & Athletic Surfaces
We lay out straight, bright stalls, with ADA stalls and access aisles marked to the required dimensions, and we stripe running tracks with measured lanes and exchange zones.

Asphalt Paving
New surfaces and overlays, with the base checked and compacted first, because that is what decides how long the top lasts.

Concrete
Curb and gutter, loading dock aprons, dumpster pads and flatwork, so the concrete and the asphalt keyed against it come from the same company.

Commercial Snow Removal
Parking lots, drive lanes and walkways cleared through the winter, on the same properties we maintain the rest of the year.
The owner
“Most outfits around here do one thing. Sealcoat, or paving, or concrete. We do all of it.”
We seal and crack fill school district lots, pour loading dock aprons and dumpster pads, patch the trench after a drain line goes in, saw cut and replace failed asphalt, rebuild catch basins, and plow the same properties through the winter. That is what full service pavement maintenance means, and it is why a property manager can hand us the whole surface instead of a piece of it.
Grant Schermitzler, ownerOn every job
How We Work
Here's what we do on every job:
- Cleaned first: blown down, edges trimmed back, oil spots primed
- Cracks filled hot with direct-fire rubber, which bonds to the crack walls and flexes through the freeze
- Sand and additives mixed into the sealer for traction
- Edges and the garage apron cut in by hand, with a clean line where the sealer meets your garage door
- A second coat on high-wear areas that need it

We seal every job with Pitch Black, a commercial-grade asphalt emulsion, and we name it because you should know what's going on your pavement. It contains no coal tar; third-party lab tests published at CoalTarFreeUSA.com measure it at 0.00% PAHs. Why we use Pitch Black
The Wisconsin Asphalt Pavement Association's parking lot design guide says sealer does nothing for pavement that has already failed, and we bid to that. The walk-through separates what can be sealed from what needs repair first, and what can wait. We do the sealing and the repairs.
