Get matched with top driveway sealcoating pros in Brainerd, MN

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.

Ideally, you should seal your driveway when there won’t be rain for several days, but at a minimum, there can’t be rain for at least 24 hours. If it rains shortly after you seal your driveway, the water can wash away the sealer and render your work useless. You’ll have to wait for your driveway to dry out and try applying again. Note that some sealers—like oil-based sealers or specialty fast-drying sealers—may cure faster. Ask your contractor for information on timing before the install, and if there’s rain in the forecast, postpone the job.

When hiring an asphalt paving contractor to install your driveway, ask as many questions up front as possible. Here are a few questions to ask a prospective driveway contractor:

• How many years of experience do you have?

• Are you licensed, bonded, and insured?

• Do you have worker’s compensation?

• Do you use subcontractors on your projects?

• Do you clean up after the job is done?

• Who is responsible for any damage to lawn or landscaping?

• Do you provide a guarantee or warranty on your work?

• Do you give free estimates?

• What is the timeline for completion?

• How do you handle change orders?

• Can you provide at least three references?

• Can I see some of the work you’ve done?

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.
