the sun loses this round.

Mariposa is Gold Rush country serving Yosemite’s Highway 140 corridor — a historic county seat where park traffic meets 1850s streets.
Lodging and restaurant parking earns its keep here every summer, and the surrounding foothill properties bring the classic mountain mix of graded drives, culverts and switchback approaches.
Grades around Mariposa mean water moves fast and carries gravel with it; interceptor swales and thickened downhill edges are standard drawing items on our gold-country quotes.
What we see in Mariposa: lodging and restaurant parking that earns its keep every park season, plus foothill drives with culverts and switchbacks to respect. The route out is Highways 140 and 49 — a run our crews have made more times than anyone’s counted.
Sealcoat in Mariposa
What sealcoating does here.
If asphalt is the investment, sealcoating is the maintenance plan that makes it last. The material is a protective emulsion that shields the binder from UV, slows water intrusion, and keeps the surface uniform and black. On the schedule the Valley climate demands — roughly every two to three years for a working lot — it routinely doubles the life of the pavement it protects.
How the work goes down.
Our crews prep before they seal: sweep and scrub, degrease the drip spots, hot-fill the cracks. Then two coats, edges cut clean, cure time honored before traffic returns. On commercial lots we sequence sections and coordinate cones and timing with your operating hours so customers always have somewhere to park.

Sealcoat questions
Asked before every
Mariposa job.
How often should asphalt be sealcoated here?
In the Valley: 2–3 years for commercial lots, 3–5 for residential driveways. The sun here is harder on asphalt than the traffic is.
Is sealcoating worth it on an old driveway?
It depends what's under it. Sealer protects sound asphalt beautifully, but it won't glue a failing surface back together — if the driveway is alligatored or soft, that money belongs in repair or repaving. We'll tell you which at the estimate, free.
