Driveway Sealcoating in Mapleton, Oregon: 2026 Cost Guide

Sealcoating on the Wet Coast Range

Mapleton sits in western Lane County on the Siuslaw River, along Highway 126 in the Coast Range between Eugene and Florence. This is some of the wettest country in Oregon, with heavy rain for months and the damp, salt-tinged air of the nearby coast. That climate is exactly why sealcoating earns its keep here. Sealcoat is the protective layer that keeps water, UV, and oxidation from breaking down asphalt, and in a place where water never lets up, keeping it out of the pavement is the whole point. A driveway sealed on a regular cycle lasts far longer than one left bare to the coastal wet.

Cojo Excavation & Asphalt sealcoats driveways across Mapleton and the lower Siuslaw from our Willamette Valley base, running west on Highway 126 through the Coast Range. We use the right material for a coastal watershed and apply it during the narrow window when the weather allows a proper cure.

What Sealcoating Does

Sealcoating is not paving and it is not repair. It is maintenance, the asphalt equivalent of repainting a house before the siding rots. A fresh seal does several things, and every one of them matters more in Mapleton's climate:

• Blocks water — Seals the surface so the Coast Range's relentless rain cannot soak into the asphalt, which is the leading cause of cracking and base failure here.
• Resists UV and oxidation — Slows the sun-driven drying that makes old asphalt brittle.
• Sheds oil and chemicals — Helps the surface resist fuel and oil drips that soften asphalt over time.
• Restores appearance — Brings a faded, weathered gray driveway back to clean black.

For the full rundown on how sealcoat works and what it is made of, see our what is sealcoating guide.

Coal-Tar vs. Asphalt-Emulsion

The two common sealer types perform differently, and near a river and the coast, the environmental angle carries extra weight.

• Asphalt-emulsion sealer — A water-based product that is lower in odor and VOCs and more environmentally friendly. It is the sensible choice near the Siuslaw and a coastal watershed, and it performs well for typical residential driveway traffic.
• Coal-tar sealer — More resistant to oil, fuel, and chemical spills, traditionally favored for high-traffic or commercial surfaces. It carries more environmental and regulatory considerations, which matter a great deal near a river that feeds the coast.

For most Mapleton residential driveways, an asphalt-emulsion sealer is the practical, watershed-friendly choice. We walk you through the tradeoffs based on your surface and how close you are to the water.

Industry Baseline Pricing for Sealcoating

Sealcoating is one of the more affordable forms of asphalt maintenance, which is what makes it such a good value against Mapleton's punishing wet. 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

Sealcoating costs a small fraction of what resurfacing or replacing a driveway runs, and in a climate this wet, that protection pays off faster than almost anywhere. Most jobs include crack filling first, because sealing over open cracks does not solve the underlying problem.

The Coastal Cure Window Is Narrow

This is where local knowledge matters most. Sealcoat needs dry pavement, dry weather for the cure, and temperatures generally above 50°F to bond and harden. Mapleton's long, heavy wet season compresses the workable window into a short, dry stretch in the heart of summer. Trying to seal outside that window, on damp pavement or with rain on the way, ruins the application and wastes the money. The coastal air can hold moisture even on dry days, so timing and surface prep are everything.

Our best time to sealcoat in Oregon guide covers the timing in detail. For Mapleton, the short version is: plan for midsummer and book early, because the dry window is brief and fills fast.

Recoat Cadence

Sealcoat is not permanent. In a coastal, heavy-rain climate, most driveways benefit from a recoat every two to three years, sometimes sooner on exposed surfaces, depending on traffic and weathering. Wait too long and the asphalt oxidizes and cracks, at which point you are into driveway repair rather than simple maintenance. Staying on a two-to-three-year cycle is what keeps a Mapleton driveway out of the repair-and-replace spiral.

Why Mapleton Property Owners Choose Cojo

Sealcoating looks simple, which is why it is so often done badly, on damp pavement, over uncleaned surfaces, or in the wrong week of a coastal summer. We prep the surface properly, fill the cracks first, choose a sealer that suits a riverside watershed, and apply it only when the weather genuinely cooperates. The run west on Highway 126 from our base is routine, and we treat a sealcoat as the cheap insurance it is meant to be against the coastal wet.
