Get matched with top driveway sealcoating pros in Kettering, OH

The best time to seal a driveway is during periods of mild, dry weather, typically from late spring through early fall. For the sealant to bond and cure properly, it needs warm conditions. Avoid sealing in the winter when temperatures are too low.

For optimal results, follow these guidelines:

• Temperature: Apply sealant when air and surface temperatures are consistently above a minimum of 50-55°F. The ideal range is often between 60°F and 80°F. Avoid applying sealer in extreme heat (above 90-95°F), as it can cause the sealant to dry too quickly and improperly.

• Weather: Choose a time with no rain in the forecast for at least 24 to 48 hours after application. Rain can wash away the sealant before it has fully cured.

• Timing and Cost: While spring and fall offer ideal temperatures, they are also the busiest seasons for driveway sealing companies, which may lead to higher costs due to increased demand. The best specific month will depend on your local climate.

Sealing coat asphalt after 6-12 months and then every 2-3 years is recommended.

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.

If you notice minor cosmetic problems with your driveway, you should seal it. Look out for cracks and holes on the surface, faded asphalt or concrete, and stains from oil and other chemicals. Replacing your driveway may be necessary if you’re dealing with significant problems—¼-inch cracks, large potholes, and puddles from drainage issues. The cost to install an asphalt driveway typically ranges between $4,200 and $9,000, significantly more than resealing. Consider talking to a professional to discuss whether resurfacing your driveway—a midway project between resealing and replacing—is a better option for you.
