Driveway Sealcoating questions, answered by experts

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.

In general, crack fillers last for about two years on average. That timeline can be shorter if you have extremely harsh winters or longer if you live in a mild climate. Luckily, this product is pretty affordable at the hardware store (about $10 to $30) and easy to DIY, so redoing it every few years shouldn’t be too much of a hassle.

Since freeze-thaw cycles throughout the winter months can damage your driveway, it's best to winterize your driveway in the late fall before the first freeze hits. Doing so will help to protect your driveway from damage throughout the winter season. Plus, drier, warmer weather makes applying and curing sealant much easier.

Like all driveway materials, asphalt can crack in the wrong conditions and with age. Many things can cause asphalt to crack, including shifting soil or settling under the foundation. Other common causes are driving oversized vehicles on the asphalt, tree roots, and using rock salt during the snowy season. Proper installation and sealing the driveway every 10 years can help prevent cracks.

It depends on the type of sealer. Some sealers can dry in as little as 4 hours, but many can take up to 48 hours to fully cure. To play it safe, don’t drive on your driveway for two days after sealing.
