Driveway Sealcoating FAQs, answered by experts

When hiring an asphalt paving contractor to install your driveway, ask as many questions up front as possible. Here are a few questions to ask a prospective driveway contractor:

  • How many years of experience do you have?

  • Are you licensed, bonded, and insured?

  • Do you have worker’s compensation?

  • Do you use subcontractors on your projects?

  • Do you clean up after the job is done?

  • Who is responsible for any damage to lawn or landscaping?

  • Do you provide a guarantee or warranty on your work?

  • Do you give free estimates?

  • What is the timeline for completion?

  • How do you handle change orders?

  • Can you provide at least three references?

  • Can I see some of the work you’ve done?

Ideally, you should seal your driveway when there won’t be rain for several days, but at a minimum, there can’t be rain for at least 24 hours. If it rains shortly after you seal your driveway, the water can wash away the sealer and render your work useless. You’ll have to wait for your driveway to dry out and try applying again. Note that some sealers—like oil-based sealers or specialty fast-drying sealers—may cure faster. Ask your contractor for information on timing before the install, and if there’s rain in the forecast, postpone the job.

Driveway sealcoating costs around $500 on average, or between $1.25 and $1.50 per square foot for materials and labor. Most homeowners pay between $250 and $800 for this service. Your project price will depend mostly on the size of your driveway, the type of sealant, how much pressure washing or treatment is required before sealing, and the number of coats of sealant applied to your driveway. Most sealants come in 5-gallon or 55-gallon units, with up to 500 square feet of coverage per 4 gallons.

If the goal is to reduce your lifetime asphalt driveway repair cost, driveway sealers with oil bases tend to last longer because their composition allows them to penetrate deeper into your driveway's asphalt. This provides deeper, longer-lasting protection compared to water-based products that tend to simply sit on the surface of the asphalt. Knowing that you won't have to redo your driveway as often could leave more room in your budget to cover something like the cost of a heated driveway.

Oil-based sealers generally offer longer results for driveways in cold climates. If you experience extreme temperatures, oil sealants offer a level of flexibility that makes them expand and contract along with the freeze-thaw cycle instead of cracking.
