Driveway Sealcoating questions, answered by experts

Many services include sealing as part of the repair process. Confirm with your provider.

Regular sealing, drainage management, and debris removal help prevent asphalt deterioration, protecting and extending surface life.

Sealing coat asphalt after 6-12 months and then every 2-3 years is recommended.

It is not recommended to seal brand-new or uncured asphalt immediately after installation. You should wait at least three months to allow the asphalt time to cure. Applying a seal coat too soon can trap the asphalt's oils and chemicals, preventing it from fully hardening. This can lead to a weaker surface that is more vulnerable to damage. After the initial three-month curing period, applying a seal coat can extend the asphalt's life by protecting it from water, UV rays, and other damaging elements.

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.
