Driveway sealing is an important process for protecting your driveway and ensuring it lasts. When left unsealed driveways are exposed to weather, vehicle fluids, general wear, and oxidation which causes your driveway to decay and fade. These factors can all lead to your driveway developing cracks and potholes. When properly maintained driveways can last up to 30 years. proper sealing and maintenance will save you money in the long run and keep your driveway looking brand new.
