Driveway Sealcoating questions, answered by experts

DIY sealants exist, but professional application ensures uniform coverage and long-term durability.

We don’t recommend sealing brand-new asphalt; instead, wait for at least three months so that the asphalt has some time to cure. If it’s applied too soon, the seal coat can trap oils and chemicals in the asphalt, preventing it from fully curing and leading to a weaker surface that’s susceptible to damage. 

Yes, you can seal asphalt before it’s fully cured but you should wait to do so until at least three months after installing it. Otherwise, the seal coat can trap the asphalt’s oils and chemicals, preventing it from fully hardening. This can lead to a weaker surface that’s vulnerable to damage. But if you wait at least three months, applying a seal coat can extend its 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.

If your asphalt driveway shows cracks, potholes, or standing water, it’s likely time for a repair. Cracks, big or small, let water seep in, weakening the base and causing further damage. Potholes are a sign of this weakening process in action while standing water suggests your driveway has poor drainage, which can cause even more issues. You may also see warping or buckling—a sign of a compromised base layer—or sinking pavement. Spotting these signs early on can help you save yourself a bigger repair bill in the future.
