"Javier at TN Construction was amazing! As project manager (and worker) he was thorough, professional, knowledgeable, and a great guy to work with. He listened carefully to my questions and proposals for what we wanted done, then followed through precisely. He was quick to respond to texts. And, most shockingly of all in my experience with contractors, his crew was at our house, prepared, with everything they needed, exactly when he said they would be! They went the extra mile to please us and they certainly did! I feel confident that Javier and his crew would go that extra mile for all their clients."

Driveway Sealcoating questions, answered by experts

The three most common types of asphalt are hot asphalt, MC cold mix, and UPM asphalt. Hot asphalt is used most often for paving and patching roadways while it’s hot and workable. MC cold mix asphalt cures more slowly than hot asphalt, but it can be used for temporary patches and repairs in low-traffic areas. UPM is also used cold, but it can be used as a longer-term fix, usable in almost any conditions at almost any temperature.

Hot-pour sealants have an asphalt cement base that might also include rubber and other materials to allow the seal to flex in hot or cold temperatures. Asphalt emulsion sealants are not heated but are liquid applications that use water and an emulsifying agent to allow the asphalt and water to mix.

Sealant comes in 5-gallon buckets that can cover up to 400 square feet. Measure your driveway to get the exact square footage, and remember to factor in enough sealant for two coats.

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.

A properly applied asphalt driveway sealer, or sealcoat, should last between one and five years. The industry standard is to reseal every two to three years for optimal protection. If you live in a climate with extreme weather, such as heavy rainfall or freezing temperatures, you may need to reseal your driveway more frequently, around every two years. Signs that your driveway needs a new coat of sealant include the appearance of small cracks or uneven drying after rain.
