Expert Chip Seal & Asphalt in Cortez & Dolores, CO

Chip seal is a surface treatment: hot liquid asphalt emulsion is sprayed onto the existing surface, aggregate chips are spread on top, and a roller presses them in. It costs significantly less than full asphalt and performs well on low-to-moderate-traffic driveways and rural roads. Hot-mix asphalt is poured and compacted into a solid, smooth mat better suited to higher traffic loads, heavier vehicles, or situations where appearance and surface smoothness are priorities. The right choice depends on your traffic level, site drainage, soil conditions, and budget.

A properly applied chip seal in southwest Colorado typically holds up 7 to 10 years before reapplication is needed. Longevity depends on drainage quality, sun exposure, traffic load, and how promptly small cracks are addressed. The high-UV environment at elevation and the freeze-thaw cycles through winter are harder on surfaces here than in lower-altitude regions — which is why routine sealcoating and timely crack filling extend pavement life meaningfully.

The practical working window in Montezuma County runs from late May through mid-October. Both chip seal and sealcoating require surface temperatures above 60°F and at least 24 hours without rain after application. Summer books up quickly — if you’re planning a spring or early-summer project, reaching out by March or April gives you the most scheduling flexibility.

For chip seal, we ask that you wait at least 24 hours before normal vehicle use, and avoid sharp turns or quick stops for the first week while the emulsion fully cures and the aggregate sets. Sealcoating typically needs 24 to 48 hours of drying time depending on temperature and humidity. We’ll give you specific guidance based on your project and the current forecast before we leave the site.

We handle both. Residential driveways are our most common project type, but we also take on commercial parking lots, private ranch and farm roads, and other paved surfaces. Commercial sealcoating is priced at a lower per-square-foot rate because of project scale, and we plan the work schedule to minimize disruption to your business. Call us to talk through your specific site.

Before the crew arrives, clear vehicles, equipment, and any belongings from the work surface and the area immediately around it. Turn off any sprinkler systems near the work zone. Mark the locations of irrigation heads, buried lines, or edge obstacles so we can work around them carefully. We handle the rest: blowing off debris, masking curbs or garage door thresholds, and protecting any adjacent concrete or landscaping during the application.
