Driveway Sealcoating questions, answered by experts

Like all driveway materials, asphalt can crack in the wrong conditions and with age. Many things can cause asphalt to crack, including shifting soil or settling under the foundation. Other common causes are driving oversized vehicles on the asphalt, tree roots, and using rock salt during the snowy season. Proper installation and sealing the driveway every 10 years can help prevent cracks.

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.

Yes, most professional repair services include the application of sealants for weatherproofing or waterproofing. This process helps protect the repaired area from moisture, weather damage, and future wear, which can improve durability and energy efficiency. It is always best to confirm with your contractor or service provider if sealing is included in their repair process.

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.

Most sealing projects take 1-2 days, including drying time before allowing traffic.
