Driveway sealcoating in Prosser.

What the work involves

Sealcoating a driveway means cleaning the surface, treating what needs treating, sealing the cracks, and rolling OverKote sealer over the top. It is the coating that takes the sun and the plow wear instead of your asphalt taking it.

Why it matters at this elevation

Sealcoating up here is protection, not decoration, although the black finish is a fair bonus. It shields the asphalt binder from ultraviolet light, closes off the fine surface porosity that lets water wick in, and gives plow blades a sacrificial surface to scrape instead of the pavement.

At roughly 5,800 feet, this pavement runs through the full mountain freeze-thaw cycle every winter. Pavement here dries out earlier in the spring than the ridge communities do, which usually means the working season opens a few weeks sooner. That does not make it mild. It still cycles through freezing and thawing constantly on both shoulders of winter, and that cycling is what opens cracks.

How the job runs

A typical job runs clean, crack seal, coat, then cure. Cure time is the part owners underestimate. Vehicles stay off at least a day, longer if the pavement is shaded or the nights are cool, and turning a wheel while parked on a young coating will scuff it.

Prosser pavement specifically

This is driveway work almost entirely, plus the shared access roads that serve the properties strung along the creek. Long approaches are the norm, and long approaches mean crack sealing is usually the bigger line item rather than the coating itself.

Prosser sits north of Truckee off Highway 89, in the country around Prosser Creek Reservoir.

For a coating to be worth applying here, the surface underneath has to be sound and the cracks have to be closed first. We check both before quoting a seal.

Prosser sits at roughly 5,800 feet, and the pavement around it behaves accordingly. More on the area on our Prosser service area page. We work the same corridor through Truckee, Glenshire, Tahoe Donner, Sierra Meadows, and the pavement guides go deeper on the physics if you want it.
