How Much Does Asphalt Sealcoating Cost in Oshkosh, WI? (2026 Guide)
These are observed market ranges for Oshkosh and the surrounding Winnebago County towns, not quotes. Sealcoating is priced by area and by condition, so two driveways of identical size can land at different numbers if one needs 60 feet of crack filling and the other needs none. Fox Valley pricing sits close to the national midpoint. What pushes an Oshkosh job up is almost always preparation: crack work, oil spot priming, and edge cutting where clay silt and grass have crept over the pavement.
| Service | Typical Oshkosh Range |
|---|---|
| Driveway sealcoating, two-car (about 600 sq ft) | $150 - $325 |
| Sealcoating priced by area | $0.15 - $0.30 per sq ft |
| Driveway sealcoating, long or double-wide (1,000 - 1,500 sq ft) | $250 - $525 |
| Hot rubber crack filling, cracks under 1/2 inch | $1.00 - $3.00 per linear foot |
| Crack sealing, routed cracks 1/2 to 1 inch | $2.00 - $5.00 per linear foot |
| Crack filling minimum visit | $150 - $250 |
| Pothole and small area patching | $50 - $200 per repair |
| Parking lot sealcoating | $0.12 - $0.25 per sq ft |
What Changes the Price?
Condition of the surface. A driveway sealed on schedule takes two coats over clean asphalt. One left seven years needs crack filling, oil spot priming and sometimes patching first, and the preparation can cost more than the sealer.
Access and edges. Driveways with no curb, where the asphalt edge meets lawn, need cutting back before sealing and are slower to do. Tight lots, gated properties and anything that has to happen after hours cost more per square foot than an open driveway on a weekday.
Timing in the season. The reliable Oshkosh window runs May through September, and the middle of it is the busiest. Booking in May or in the first half of September usually finds better scheduling than trying to get on a calendar in July.
Whether the base is sound. This is the big one. Sealcoating a driveway that flexes underfoot is a cosmetic purchase with a short life, and the honest version of that conversation happens before the quote rather than after.
Treat any bid dramatically under these ranges with suspicion, and ask what is being left out. The usual answers are one coat instead of two, no crack filling, or sealer thinned well past what the manufacturer specifies. All three look identical on the day the crew leaves and all three show by the following spring.
