Get matched with top driveway sealcoating pros in Alpine, UT

Maintaining a driveway depends on its material. For concrete and asphalt, it's best to clean the surface thoroughly twice a year with a stiff broom and a pressure washer to remove accumulated dirt and debris. Sealing the driveway is crucial to protect it from water damage and freeze-thaw cycles. Before applying a sealant, pressure wash the surface to remove any loose sealant, dirt, or stains, as sealing over them will trap them. Any cracks or expansion joints should be filled with a flexible polyurethane caulk or asphalt sealer. In colder climates, use sand instead of salt for de-icing. Sand helps melt snow and ice without accelerating the freeze-thaw process, which can cause cracks.

In general, crack fillers last for about two years on average. That timeline can be shorter if you have extremely harsh winters or longer if you live in a mild climate. Luckily, this product is pretty affordable at the hardware store (about $10 to $30) and easy to DIY, so redoing it every few years shouldn’t be too much of a hassle.

Instead of a set number of types, asphalt comes in variations designed for different needs. Some are categorized by temperature—hot mix, warm mix, and cold mix. Others are sorted by composition, like dense-graded, gap-graded (such as Stone Matrix Asphalt), porous, and mastic asphalt. There are also modified versions with added compounds like polymers, rubber, or emulsions. Instead of focusing on a number, it may be more useful to understand how contractors customize asphalt for durability, climate, and traffic conditions.

Driveway sealcoating costs around $500 on average, or between $1.25 and $1.50 per square foot for materials and labor. Most homeowners pay between $250 and $800 for this service. Your project price will depend mostly on the size of your driveway, the type of sealant, how much pressure washing or treatment is required before sealing, and the number of coats of sealant applied to your driveway. Most sealants come in 5-gallon or 55-gallon units, with up to 500 square feet of coverage per 4 gallons.
