What We Do
Our Services
Sealcoating
We apply a protective coal-tar or asphalt-based sealer that shields your pavement from UV rays, water damage, and daily wear — extending its life for years.
Learn more →Crack Filling
Before cracks become costly potholes, we seal them tight with hot-pour rubberized filler that flexes through Wyoming's freeze-thaw cycles.
Learn more →Pothole Repair
Fast, durable pothole patching that restores a smooth, safe surface — for driveways, parking lots, and private roads.
Learn more →Line Striping
Fresh, crisp parking lot lines and markings that improve safety, flow, and curb appeal for commercial and residential properties.

What Customers Say
Trusted Across the Wind River Region
"307 Grizzly did our driveway last fall and it looks brand new. They showed up on time, worked clean, and the price was fair. Will definitely call them again next season."
"We had a nasty pothole at the entrance to our parking lot that was becoming a liability. They came out the same week, fixed it properly, and you can't even tell it was there. Great local crew."
"Honest, hardworking guys. They walked me through exactly what needed to be done and didn't try to upsell me on anything I didn't need. My driveway is holding up great through the winter."
