Driveway Sealcoating questions, answered by experts

What causes driveways to crack can vary by driveway material. Sealcoating with the right formula creates a protective "shell" over a driveway. Resealing a driveway on schedule helps to preserve its lifespan substantially by keeping it protected against damage from UV rays, motor oil, chemicals, hail, rain, snow, and more. If you don't reseal your driveway, this will lead to brittleness, cracking, and potholes that can eventually cause your driveway to fall apart.

Proper surface prep and application techniques by pros minimize peeling, ensuring longevity.

Though they may look similar, tar and bitumen come from different sources. Bitumen is a petroleum product—extracted during crude oil refining—and is mostly made up of hydrocarbons. Tar comes from burning down organic materials like coal or wood. Bitumen is strictly oil-based, while tar is a mix of compounds from natural sources. Both are used as binders in paving; however, bitumen is the standard for today’s asphalt. Tar use has mostly faded out of road construction.

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?

Yes, you can seal asphalt before it’s fully cured but you should wait to do so until at least three months after installing it. Otherwise, the seal coat can trap the asphalt’s oils and chemicals, preventing it from fully hardening. This can lead to a weaker surface that’s vulnerable to damage. But if you wait at least three months, applying a seal coat can extend its life by protecting it from water, UV rays, and other damaging elements.
