The cost to blacktop a driveway can vary greatly depending on many factors. Some of these factors include size, materials and whether or not you hire a professional to do it. There are materials available at local hardware stores such as Lowes and Home Depot. These are materials that come in 5 gallon buckets and require you to spread it yourself. Before beginning this task you should make
. sure that there is going to be no rain. If you plan on doing it yourself, plan to use the whole weekend for a smaller size driveway. If you hire a contractor you can expect to pay $500 and up.
