LA CROSSE, Wisconsin (WXOW) Whether your driveway is concrete or asphalt, if you want to keep it looking like new, Angie's List says you should understand the importance of sealing.
Sealant sits on top of your driveway and acts as a barrier against the elements. It protects the driveway from damage caused by oil and gas spills, rain, snow and sun.
So, you might wonder how often you should seal the driveway. Angie's List says it depends on your location. If you live in a cold climate, you'll have to seal your driveway every one or two years. In milder climates, as little as every four years.
