Winter is fast approaching and this year could be cold and snowy. Now is a good time to prepare your driveway to protect it from the elements. Blacktop driveway sealer and filler will fill cracks as well as seal the asphalt with an outer coating. This is a project than can be dome by most home owners and can be completed in a weekend. The driveway first needs to be cleaned of all debris. Applying the sealer needs to be done on a calm day so the wind does not blow leaves and other debris into the sealer.
