Professional driveway sealcoating costs $1 to $2 per square foot including labor.1 Angi and HomeAdvisor both publish a tighter $1.25 to $1.50 per square foot and a $575 national average.2,3 For a typical 24’ x 24’ two-car driveway (576 sq ft), budget roughly $575 to $1,150.*

per sq ft, HA/Angi
Quick math: square footage x per-foot rate. 576 sq ft at $1.25 = $720; at $1.50 = $864 (our math on Angi’s range2). HomeGuide’s wider $1 to $2 range gives $576 to $1,152 for the same driveway.1
Published prices at a glance
Three references, all fetched and read October 2026. Note that Angi and HomeAdvisor are sister brands and publish nearly identical numbers, so treat them as one independent estimate, not two:
By driveway size
HomeGuide publishes totals by size, and our math checks out against its $1 to $2 range:1
| Driveway size | Square feet | HomeGuide total | Angi/HomeAdvisor range (our math) |
|---|---|---|---|
| 12’ x 24’ (1-car) | 288 | $290 – $580 | $360 – $432 |
| 20’ x 20’ (2-car) | 400 | $400 – $800 | $500 – $600 |
| 24’ x 24’ (2-car) | 576 | $580 – $1,150 | $720 – $864 |
| Long 12’ x 100’ | 1,200 | not published | $1,500 – $1,800 |
Sealant type changes the price
Materials alone run $0.06 to $0.38 per square foot, or $3 to $25+ per gallon, depending on the sealant.1,2 HomeAdvisor’s per-square-foot material rates by type:3
| Sealant type | Material cost per sq ft |
|---|---|
| Emulsion | $0.08 – $0.10 |
| Oil-based | $0.15 – $0.20 |
| Latex acrylic | $0.20 – $0.25 |
A 5-gallon container covers 250 to 500 square feet, so a 576 sq ft driveway needs roughly 1.2 to 2.3 buckets (our math on HomeGuide’s coverage figures1).
What else to budget for
Power washing: $0.27 to $0.39 per sq ft as an add-on; HomeAdvisor puts standalone pressure washing at $100 to $500, averaging $210.2,3
Crack fill and repairs: fill-and-seal work runs $0.60 to $1.75 per square foot when the surface is cracked or damaged; crumbling asphalt with big holes may not be sealable at all.2,3
Service fees: Angi notes local contractor service fees of $100 to $200, and warns small driveways can hit minimum labor fees.2
DIY vs hiring it out
HomeAdvisor says DIY sealing saves about $1.15 per square foot in labor3 – roughly $660 on a 576 sq ft driveway – against materials of $0.06 to $0.38 per sq ft ($35 to $219 for the same driveway, our math). The trade-off: a DIY job that fails early means paying to strip and redo it.
