With a new driveway sealed within six months to a year from installation, you should expect one to two years of protection from your first application. Subsequent sealcoat applications should last two to three years. If the driveway is 10 years old and was never sealed, you might only get one year from the first application, but two to three years from subsequent sealcoat applications. Additionally, variables such as water runoff, salt, sand, snowplowing and severe temperature swings will play a role in the longevity of your sealcoat. Anyone that promises five, six or seven years or more of coverage is simply making empty promises that you’ll have no way of enforcing. Also, while the sealer itself may last two to three years, cracks may surface which would trigger the need for treatment before the color has faded.
