Asphalt vs. Concrete Driveway Sealing Cost Guide
An asphalt driveway and a concrete driveway are both sealed, but they are two different services with two different price shapes: an emulsion coat over blacktop, and a cleaning-and-sealing service over a slab. HomeGuide 2026 data prices concrete sealing at $1 to $3 per square foot. Angi 2026 reporting averages asphalt sealcoating at $575. This guide prices the two surfaces apart, frame by frame.

The concrete side, inside the HomeGuide frame
| Concrete line | Cost, HomeGuide 2026 | Frame note |
|---|---|---|
| Cleaning and sealing, per square foot | $1-$3 | installed band |
| 2-car driveway, 576 sq ft | $575-$1,700 | acrylic or polyurethane lines |
| Labor, per square foot | $0.70-$1.25 | labor line only |
| Minimum service fee | $150-$300 | small-job floor |
| Sealer, per gallon | $30-$80 | materials line only |
Read the table as one frame's concrete pricing, never as a blended sealing price list. The HomeGuide concrete frame splits the service into a per-foot band, a labor line, a materials line, and a minimum fee, so a small slab can price at the $150 to $300 floor even when its square footage math runs lower. The 2-car total, $575 to $1,700, is the frame's headline driveway line. The asphalt side of this comparison prices from the hub frames on the driveway sealcoating cost hub.
The concrete side, inside the Angi frame
| Concrete line | Cost, Angi 2026 | Frame note |
|---|---|---|
| Sealing with labor, per square foot | $1.35-$2.50 | installed band |
| Average on a 1,000 sq ft job | about $1.50 per square foot | reported average line |
| Old-sealer removal, per square foot | $1-$3 | prep line, where quoted |
The same surface carries a second published frame, and this guide keeps both apart. The Angi concrete frame bands sealing with labor at $1.35 to $2.50 per square foot, narrower than the HomeGuide frame's $1 to $3, and reports about $1.50 per square foot on a 1,000-square-foot job. It also names a prep line the HomeGuide frame prices differently: old-sealer removal at $1 to $3 per square foot where a quote includes it. Neither frame is folded into the other, and a concrete quote should name the frame each line follows.
The asphalt side, cross-priced from the hub frames
Asphalt sealcoating prices in its own two frames, carried here without re-blending. In the Angi frame, updated October 14, 2026, the national average is $575 across 7,324 verified projects, most homeowners pay $282 to $868, and materials and labor run $1.25 to $1.50 per square foot. In the HomeGuide frame, asphalt sealing runs $1 to $2 per square foot, with totals by size from $290 to $580 at 288 square feet up to $1,700 to $3,300 for a 1,650-square-foot circular drive. Set beside the concrete bands, the shapes differ rather than the surfaces ranking: asphalt totals are stated as project averages and size bands, concrete totals as a per-foot band with labor and materials split out. Each surface is read inside its own frames.
Two neighbours, differentiated head-on
The concrete driveway cost estimator prices a different purchase entirely: a brand-new concrete driveway, estimated slab and all. Nothing on the estimator page prices sealing an existing slab; a reader pricing a new driveway belongs there, and a reader pricing the sealing service on a driveway that already exists belongs here. A third surface stands apart as well: the paver sealing cost guide prices sealer over interlocking pavers and joint sand. Paver, concrete, and asphalt are three surfaces with three price tables, and no table in this cluster stands in for another.

Frequently asked questions
What does it cost to seal a concrete driveway?
HomeGuide frame: $1 to $3 per square foot for cleaning and sealing, and $575 to $1,700 for a 2-car driveway, with labor at $0.70 to $1.25 per square foot and a $150 to $300 minimum fee. Angi frame: $1.35 to $2.50 per square foot with labor. The frames stand apart, never blended.
What does asphalt sealcoating cost, set beside concrete?
Angi frame: a national average of $575 across 7,324 verified projects, most homeowners paying $282 to $868, materials and labor at $1.25 to $1.50 per square foot. HomeGuide frame: asphalt sealing at $1 to $2 per square foot, totals by size. Each surface is priced inside its own frames.
What does concrete sealer itself cost per gallon?
HomeGuide frame: $30 to $80 per gallon as a materials-only line. That gallon line is not a service total: the same frame prices labor apart at $0.70 to $1.25 per square foot, and the installed band at $1 to $3 per square foot.
Is sealing an existing concrete driveway the same purchase as a new concrete driveway?
No, head-on: the concrete driveway cost estimator prices a brand-new driveway. This guide prices sealing a driveway that already exists, at $1 to $3 per square foot in the HomeGuide frame. New-slab pricing and existing-surface sealing are different buyer queries with different tables.
Does a small concrete driveway price by square footage alone?
Not in the HomeGuide frame: it names a minimum service fee of $150 to $300, so a small slab can price at that floor even when the per-foot math runs lower. The Angi frame names its own prep line instead, old-sealer removal at $1 to $3 per square foot where quoted.
