Driveway Sealing Cost Calculator & Price Guide

Driveway sealing puts a protective coating over existing pavement. Asphalt driveways get sealcoat, and concrete driveways get a sealer made for masonry. The job is maintenance. It does not repair a failing base or replace resurfacing, and it works best on a surface that is still sound.

The figures below come from published cost guides and carry a check date of Oct 13, 2026. LawnStarter bases its headline range on an asphalt driveway. Concrete costs more per square foot, and the tables show both.

Contractors usually quote sealing by the square foot, so you can build a rough estimate yourself in a few steps.

1. Measure the driveway length and width, then multiply to get the area in square feet.
2. Pick the rate for your surface from the table below. Asphalt and concrete are priced differently.
3. Multiply the area by the rate.
4. Add the separate items, such as pressure washing and crack repair, if the contractor does not include them.
5. Check the result against the contractor's minimum charge, which may be higher than the math suggests on a small driveway.

The rates differ because the sources describe different work. One counts only the sealcoat, while another counts materials and labor for a full professional job. When you compare quotes, ask which items the rate covers.

Concrete sealing is usually quoted for cleaning and sealing together.

A larger driveway raises the total, though unit rates can fall as the job gets bigger because travel, setup, and cleanup are spread across more pavement.

Cleaning comes first, since sealer needs a clean surface to bond. Some contractors include pressure washing in the quote, and others bill it separately.

Repairs also add to the bill. Filling cracks and patching potholes is a separate task from sealing and is billed on its own. Contractors often add a project fee for equipment, insurance, and other business costs.

Small jobs feel this fee the most, since it can make up a large share of a low total.

Reported totals stretch well past the typical range. LawnStarter lists a low end near $110 and a high end near $1,230. A small asphalt driveway in good condition sits near the bottom. A large driveway with cracks, oil spots, and repairs sits near the top.

• Surface type. Concrete sealing costs more per square foot than asphalt sealcoat.
• Size. More pavement means more material and labor.
• Condition. Cracks, potholes, and oil stains need repair or treatment before sealing.
• Cleaning. Pressure washing may be included or billed on top.
• Number of coats. A porous driveway may need a second coat once the first dries.
• Slope and access. Steep driveways are harder to coat evenly, and tight edges need hand work.
• Contractor minimums. Small jobs may be charged a flat minimum.
• Region. Local wages and crew costs vary.

National guides draw on different data and different driveway types. LawnStarter prices an asphalt driveway, so its range may sit below a guide that mixes in concrete or larger jobs. A second cost guide that compiles contractor quotes reports a professional sealing range of $250 – $900.

Read the scope behind each number. Compare asphalt to asphalt, and ask whether pressure washing and repairs are inside the quote.

Sealing protects the surface from water, sun, and oil. It does not fix structural damage. If the base has failed or the pavement has broad cracking and potholes, the job moves into repair or resurfacing and costs more. A contractor can tell you whether the driveway is a good candidate. A very steep driveway may not be.

Doing it yourself saves labor. You buy the sealer and repair materials and rent or borrow the tools. The work is physical, and the surface needs to be clean and dry with enough warm weather to cure. Professionals bring equipment and finish faster, and they handle edging and prep. Whichever route you take, follow the sealer manufacturer's instructions on temperature, surface preparation, and curing time.
