Why Sealcoating Matters in Sonoma County
Sonoma County's climate — hot dry summers, wet winters, and coastal moisture in the west — is tough on unprotected asphalt. Sealcoating is the single most cost-effective maintenance investment you can make.
UV Protection
Sonoma County's intense summer sun oxidizes and dries out asphalt. Sealcoating blocks UV rays and prevents the surface from becoming brittle and cracked.
Water Resistance
Sealer fills surface pores and prevents water from penetrating the base — critical during Sonoma County rainy seasons to prevent frost heave and base failure.
Oil & Chemical Resistance
Sealcoating creates a barrier against gasoline, motor oil, and de-icing chemicals that soften and degrade unprotected asphalt.
Restored Appearance
Fresh sealcoating restores the deep black color of new asphalt, dramatically improving curb appeal for homes and businesses.
Extended Pavement Life
Regular sealcoating every 3–5 years can double the lifespan of your asphalt — the most cost-effective maintenance investment you can make.
Easier Cleaning
A sealed surface is smoother and non-porous, making it easier to sweep, blow, and pressure-wash. Stains are less likely to penetrate.
Our Sealcoating Process
Surface Cleaning
We blow out all debris, scrub oil spots with degreaser, and allow the surface to dry completely. A clean surface is essential for proper sealer adhesion.
Crack Filling
All cracks are routed, cleaned, and filled with hot-pour rubberized crack filler. This step prevents water intrusion and is done before any sealer is applied.
Two-Coat Sealcoating
We apply two coats of commercial-grade coal tar or asphalt emulsion sealer by squeegee or spray. Two coats provide twice the protection and a uniform finish.
Cure & Inspection
We barricade the area for 24–48 hours while the sealer cures. We walk the finished surface with you before removing barricades and confirm you are satisfied.
