Dufur sits in Wasco County high-desert wheat country, south of The Dalles in the dryland farm country east of Mount Hood. The climate here is the opposite of the wet west side: hot, dry, sun-soaked summers and cold, hard-freezing winters. That combination is exactly why sealcoating matters in Dufur. The intense high-desert sun bakes and oxidizes bare asphalt, drying it out and making it brittle, while the winter freeze works on any cracks that open up. Sealcoat is the protective layer that fights both, and a driveway sealed on a regular cycle holds up far better than one left exposed to the high-desert sun and cold.
Cojo Excavation & Asphalt sealcoats driveways across Dufur and the surrounding high desert from our Willamette Valley base, running east over the Cascades and south from The Dalles. We use the right material for the climate and apply it when conditions allow a proper cure.
Sealcoating is not paving and it is not repair. It is maintenance, the asphalt equivalent of staining a deck before the wood splits. A fresh seal does several things, and in Dufur the UV protection leads the list:

The two common sealer types perform differently, and the right choice depends on the surface and how it is used.
For a Dufur residential driveway, asphalt-emulsion is usually the sensible choice. For a farm pad or shop apron where equipment leaks fuel and oil, the chemical resistance of coal-tar can be worth considering. We walk you through the tradeoffs based on how your surface gets used.
Sealcoating is one of the more affordable forms of asphalt maintenance, which makes it a strong value against the high-desert sun and freeze. The ranges below are industry baselines, not quotes.
Industry baseline ranges. Actual cost depends on driveway size, surface condition, sealer type, number of coats, and access.
| Scope | Industry Baseline Range |
|---|---|
| Driveway sealcoating | $0.15–$0.30 per square foot |
| Typical residential driveway | $150–$500 |
| Crack filling (often done first) | $1–$3 per linear foot |
| Two-coat application | upper end of range |
Local knowledge matters here too. Sealcoat needs dry pavement, dry weather for the cure, and temperatures generally above 50°F. Dufur's dry climate is actually an advantage for sealcoating, the lack of constant rain opens up a longer workable season than the wet side gets. The catch is the extreme summer heat: applying sealcoat on pavement that is too hot can cause it to dry too fast and bond poorly, so the work is often best timed to cooler parts of the day. Winter cold rules out the off-season.
Our best time to sealcoat in Oregon guide covers the timing in detail. For Dufur, the season is generous but the heat has to be managed, and we plan the timing around it.
Sealcoat is not permanent. Under the intense high-desert sun, most driveways benefit from a recoat every two to three years, depending on exposure and traffic. The UV does steady work on bare or under-protected asphalt, so letting a seal lapse too long lets the surface oxidize and crack, at which point you are into driveway repair rather than simple maintenance. Staying on a two-to-three-year cycle keeps a driveway out of the repair-and-replace spiral.
Sealcoating looks simple, which is why it is so often done badly, on pavement that is too hot, over uncleaned surfaces, or at the wrong time. We prep the surface properly, fill the cracks first, choose a sealer that suits how the driveway gets used, and time the application to avoid the worst of the heat. The run east over the Cascades from our base is routine, and we treat a sealcoat as the cheap insurance it is meant to be against the high-desert sun and freeze.
