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.

Oil can permanently stain a concrete driveway if it fully dries or sits for weeks without cleaning. Concrete is porous and absorbs the oil deeper over time. That’s why it’s best to remove an oil stain when it’s wet by applying an absorbent material, sweeping the area, applying dish soap, scrubbing, and then rinsing.

New asphalt typically needs 24 to 72 hours to dry before it can handle light foot traffic and careful driving. Although it may appear solid after a few days, the full curing process, where the asphalt reaches its peak strength, takes much longer—generally from 30 days to a year.

During this extended curing time, the surface remains relatively soft and can be damaged by heavy vehicles, sharp objects, or high temperatures. To protect your investment, it's best to avoid parking heavy machinery on the asphalt until it has fully cured.

The exact time required for drying and curing depends on several factors, including the weather, the specific asphalt mix, and its thickness. For the most accurate advice tailored to your situation, consult with your asphalt contractor.

Regular maintenance will help you avoid costly repairs and early replacement. Clean the driveway surface with a stiff brush and water at least twice yearly, and remove any weeds that try to take root. Additionally, every two to five years, apply a sealcoat—this protects the driveway against damaging UV rays and keeps it looking like new.
