Pricing is primarily based on square footage and the condition of the asphalt.
What Impacts Price:
Square footage
Prep work needed
Porosity (how much sealer it absorbs)
Layout (tight edges, open areas, slope of the driveway)
Asphalt condition and porosity can be judged differently from one contractor to another
Not all contractors use the same quality products
Application methods differ, hand brushing vs spraying. We always hand brush, which uses more material but results in a thicker, longer-lasting finish
Square footage calculations can vary
