These are observed market ranges collected from published cost guides, not quotes from any contractor. One source is specific to Duluth: Homeblue's driveway sealing estimate, dated May 2022. The others are national guides from HomeGuide, Angi and FixAsphalt, updated between 2023 and 2026. Where two sources disagree, the row shows the spread. A written quote after someone has walked the driveway is the only number that counts, and on the hillside, grade, access and apron work can move it noticeably.
| Service | Typical Duluth Range |
|---|---|
| Seal coat, single-lane drive about 12 x 40 ft (480 sq ft) | $150 - $240 |
| Seal coat, two-car drive about 24 x 30 ft (720 sq ft) | $220 - $360 |
| Driveway sealing per square foot, Duluth estimate to national full-service rate | $0.30 - $1.50 per sq ft |
| Crack filling with hot-pour rubberized sealant | $0.50 - $3.00 per linear ft |
| Single pothole or small patch repair | $100 - $400 each |
| Saw-cut, full-depth asphalt patch | $4 - $12 per sq ft |
| Commercial lot, sealcoat only | $0.14 - $0.50 per sq ft |
| Lot restriping, each ordinary stall | $4 - $5 per stall |
| Asphalt driveway, new or rebuilt, installed | $5 - $15 per sq ft |

What Changes the Price?
Grade and access. A steep hillside drive takes longer to clean, fill and coat in thin passes, the sealer needs sand mixed in for grip, and a tight lot with no place to park a trailer or stage equipment adds labor to every step of the job.
Prep before the coat. Every foot of crack filling and every square foot of patching is priced on top of sealing. A driveway that went several winters without crack work carries more of that prep, and it should appear as separate line items on the quote.
Size and minimum charges. Homeblue's Duluth page says small driveways may draw a mobilization charge of $75 to $100, and national guides list service fees from $100 to $250, which is why a short single-car drive may be priced close to a much larger one.
Product and number of coats. In HomeGuide's material prices, asphalt emulsion runs 8 to 15 cents a square foot while latex acrylic costs $0.20 to $0.25, and Angi's figure for fill-and-seal material is $0.35 to $0.50. A second coat, or a third on a heavily used apron, adds material and time.
To estimate a driveway, multiply its length by its width, add any private apron area, and apply the per-square-foot range; then add crack footage and patch areas. Ask every quote to itemize the number of coats, the sealer product, the crack footage and the patch sizes so two quotes can be compared line by line. The quote form passes the details to independent crews for a written price.
Why the local and national sealing figures differ
Plain driveway sealing shows the widest gap on this page. Working at $0.30 to $0.50 a square foot, Homeblue's Duluth estimate prices a 12 by 30 foot drive at $110 to $180 and a 24 by 30 foot drive at $220 to $360. Angi's national guide, last updated in May 2026, reports typical jobs from $282 to $868 and a combined materials-and-labor rate between $1.25 and $1.50, while HomeGuide's 2023 guide runs from $1 to $2.
Angi's own regional averages show how much a national number blends: about $370 for a job in Ohio, $600 in Florida and $2,450 in Texas. A sound two-car Duluth driveway with little crack work can reasonably be expected to price nearer the local estimate, while a steep drive with heavy cleanup, many cracks or a small-job minimum drifts toward the national figures. The line items, not the total alone, show which case applies.
Permits, aprons and deposits
Sealing and patching private pavement are not on Duluth's engineering permit list, but a new or changed apron is. The city's driveway apron permit costs $135, a $65 base fee plus a $70 inspection fee, and it is issued only with a $10,000 surety bond and general liability insurance on file. The apron is concrete to the city's detail, 7 inches thick for homes on a 12-inch gravel base, and that concrete work is priced separately from the asphalt.
In Hermantown, a driveway access permit carries a $350 application fee and a $250 installation deposit that is refunded after final inspection, and the owner supplies the culvert the city specifies. Those amounts belong in the budget for any new or relocated driveway on the hilltop, alongside the paving itself.
Parking lot and striping prices
Lot pricing in FixAsphalt's guide starts at $0.20 to $0.50 a square foot for sealer alone; crack sealing lifts it to $0.60 to $0.80, and striping on top brings it to $0.65 to $0.90. By the same guide, a small lot of 4,000 to 7,000 square feet runs about $1,200 to $2,100. Angi's 2026 figure for lot sealcoating is lower, $0.14 to $0.25. HomeGuide's restriping figures: each ordinary stall $4 to $5, each accessible one $25 to $40, an arrow or stop bar $10 to $30, and a mobilization charge of $150 to $350 on top.
Asphalt Sealcoating Pricing Questions
What does a pothole repair cost compared with a full-depth patch?
A single pothole typically costs $100 to $400 in HomeGuide's 2025 guide. Measured by area, the same guide lists cold patch from $2 to $4 a square foot, hot patch from $2 to $5, infrared work from $2 to $6 and saw-cut, full-depth repair from $4 to $12, and many contractors add a service minimum in the $100 to $250 range. The deeper the failure reaches into the base, the closer the job moves to the saw-cut price.
How does an overlay compare in price with a new driveway?
An overlay over a sound base runs about $1 to $4 per square foot in HomeGuide's repair guide and Angi's 2026 repair guide, though HomeGuide's driveway guide lists resurfacing at $3 to $7. A new asphalt driveway runs $5 to $12 per square foot in HomeGuide's 2025 figures, and Angi puts tear-out and replacement at $8 to $15. The overlay only makes sense when the base underneath is still sound and drains.
Is there a discount for booking asphalt work off-season?
HomeGuide notes that winter installations can save 10 to 15 percent where the climate allows them. In Duluth, frost and the short season limit that option: MnDOT bars the final wearing course on its own projects after October 15 north of the Browns Valley to Holyoke line, and sealer needs 50 degrees and rising. Planning and requesting quotes in late winter is the practical alternative.
