Generally, a residential driveway sealcoat will last 2 years. There are some factors that will affect the life of your sealcoat like the amount of use your driveway gets (if you have several drivers in your household verses just one). The amount of snow and how it’s removed is also a factor. If you have a snowplow removing snow, that will cause more wear and tear than if it’s hand shoveled, for example.
