Driveway Sealcoating questions, answered by experts

Sealing your driveway gives it the longest possible lifespan. You’ll reduce your driveway’s risk of cracking, breaking down from exposure to UV light, discoloring, and staining from road chemicals.

If you don’t want to seal the entire driveway using a squeegee, you can use a roller instead. Rolling the driveway sealer also provides an even, sufficient coating, although it might require more skills to control the speed and pressure. We don’t recommend spraying the driveway sealer because it would cause more splash, hence wasting more material. If anything, you may spray the sealant and go over the surface again with a squeegee to ensure proper coating.

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.

Chip seal lasts only 5 to 8 years on average. This lifespan is significantly shorter than asphalt. It is also less durable. Therefore, chip seal driveway only works if the traffic volume is extremely low. Chip seal is also less resistant to storms and hails. As impact builds up, the chips may become misplaced, creating an uneven driving surface that sometimes becomes hazardous and may damage your tires or cause your vehicle to lose balance.

To maintain your asphalt driveway, add a new coat of sealant every three to five years. Pricing varies, but you will pay about $0.08 to $0.50 per square foot from start to finish. You can also choose to add a fill-and-seal layer that includes a layer of aggregate to fortify a damaged top layer of asphalt.
