Driveway Sealcoating
Riley’s Asphalt protects residential driveways across Castle Rock and Douglas County with sealcoating that extends pavement life and keeps your driveway looking its best.
Over 30 Years Protecting Castle Rock Driveways
For more than three decades, Riley’s Asphalt has sealcoated driveways throughout Castle Rock and Douglas County. We’re a family-owned company that understands how Colorado’s intense UV exposure at 6,200 feet elevation and dramatic temperature swings break down asphalt driveways faster than in lower-elevation markets.
Our A+ BBB accredited rating and over 40 five-star Google reviews come from Castle Rock homeowners who trust us to protect their driveways with honest assessments and quality work. We’re fully insured and carry comprehensive workers’ compensation coverage on every project.

High-Elevation UV Protection
Castle Rock’s 6,200-foot elevation means your driveway faces more intense UV radiation than driveways at lower elevations. This accelerates oxidation, turning asphalt gray and brittle. We apply premium asphalt emulsion sealers that restore protective oils, block UV damage, and bring back that rich black color. The sealer creates a weather-resistant barrier that keeps water from penetrating surface cracks and prevents the freeze-thaw damage common in Douglas County winters.
Environmentally Responsible Sealers
We use high-quality asphalt emulsion sealers instead of coal tar products. Asphalt emulsion provides excellent driveway protection while being safer for your family, pets, and landscaping. There’s minimal odor during application and curing, so you won’t deal with the harsh chemical smell that lingers for weeks with coal tar. The sealer produces a deep, pitch-black finish that makes driveways look freshly paved.
Strategic Application Timing
We recommend sealcoating Castle Rock driveways every 2-3 years depending on sun exposure and use. Driveways on south-facing slopes receive more UV damage and may benefit from more frequent application. We only sealcoat when weather conditions support proper curing—overnight lows above 50°F and daytime temperatures reaching at least 60°F with no rain in the forecast for 24 hours.
How Sealcoating Protects Your Driveway
Driveway sealcoating creates a protective layer between your asphalt and Colorado’s harsh climate. Without protection, Castle Rock driveways face constant degradation from:
- UV oxidation that dries out asphalt binder and causes surface cracking
- Freeze-thaw cycles that expand existing cracks into larger damage
- Water penetration that softens the base and creates settling
- Gasoline and oil drips that break down asphalt binder
- Snowplow scraping during winter maintenance
Our sealcoating process starts with power washing to remove dirt, debris, and any vegetation growing in cracks. We fill cracks wider than 1/4 inch with hot-pour rubberized crack filler that flexes with temperature changes. Then we apply two coats of commercial-grade asphalt emulsion sealer using professional spray equipment for even coverage.
The sealer penetrates surface oxidation and creates a moisture-proof barrier. Properly sealcoated driveways in Castle Rock typically last 15-20 years before requiring replacement, compared to 8-12 years for driveways that are never sealed. The cost of sealcoating every 2-3 years is a fraction of what you’d spend on driveway replacement.
