In Boise, asphalt should be sealcoated every 2-4 years, depending on traffic, weather exposure, and the condition of the pavement. Parking lots will fall closer to the 2-3 year mark, whereas driveways will be closer to 4 years per treatment. It's important to not seal too often as this can lead to the sealer flaking or cause improper bonding to occur. If you begin to notice the sealer fading, and cracks starting to appear, that's a good time to get your asphalt evaluated.

The best time to sealcoat asphalt in Idaho is typically between late spring and early fall, when temperatures stay consistently above 50°F. In Boise and throughout southern Idaho, the ideal sealcoating season is usually May through September. For optimal results, apply sealcoat during warm, dry days, when the temperature won't drop below 50 degrees for 24-48 hours. This is a great time of year to repair any damages that were sustained over the winter months.

The cost of sealcoating is based on the square footage of asphalt and varies based on several factors. We evaluate parking lots based on condition, looking for cracks and potholes that need to be repaired, the amount of cleaning that needs to be done prior to sealing, and the overall age of the asphalt.

Most asphalt sealcoat dries enough for foot traffic within 4–8 hours and is typically ready for vehicle traffic within 24–48 hours, depending on weather conditions. Drying time is dependent on humidity, temperature, and thickness of application. For best results, we recommend waiting at least 24 hours before opening your parking lot to vehicle traffic.

The short answer, no. Sealcoating alone does not repair cracks and potholes. Significantly damaged asphalt requires a more comprehensive approach including, pothole patching, crack sealing, and mastic application. When we give parking lot sealcoating estimates, we include these services as necessary to keep your asphalt properly maintained.

Sealcoating helps protect asphalt driveways and parking lots from damage caused by sunlight, water, oil spills, snow, and Idaho’s freeze-thaw weather cycles. Over time, unprotected asphalt can dry out, fade, crack, and develop potholes that lead to expensive repairs. In Boise, sealcoating is especially important because hot summers and winter moisture can quickly wear down untreated asphalt surfaces. Most asphalt driveways and parking lots in Boise should be sealcoated every 2–3 years to maintain durability and appearance.
