Asphalt Sealcoating in Raleigh, NC

Sealcoating is the process of spraying and/or squeegee applying asphalt or coal tar based sealer to your parking lot. This sealer, when applied properly, will help protect your asphalt investment. We liken it to staining your deck. Over time, the sun, water, and traffic can wear out your asphalt surfaces, making them hard, brittle and more susceptible to failure. For parking lots and asphalt surfaces in need of a facelift, we offer sealcoating services that protect the binder in your pavement to prevent deterioration from the sun and wear and tear.

Sealcoating also enhances the aesthetics of your lot, giving old, grey asphalt a rejuvenated appearance. Sealcoating is recommended every 2-3 years, and is most effective during the early stages of your parking lot’s lifespan, to help lock in and preserve its original asphalt oils. We are one of the largest providers of sealcoating products in the Carolinas. We place over 40,000 gallons of sealer each year throughout North Carolina.

Benefits of Asphalt Sealcoating

Asphalt sealcoating
  • Prevents oxidation caused by harmful rays from the sun (which can wear away 50% of the asphalt’s original thickness in just 5 years)
  • Improves the appearance of your asphalt with a rich, black finish
  • Resists salt, oil, gas and chemical penetration
  • Prevents moisture from rain and snow from seeping into pavement during freeze-thaw cycles
  • Considerably reduces maintenance costs and can extend the life of your pavement by up to 300%


While all parking lots benefit from sealcoating, different surfaces will respond in different ways. Sealcoating does not restore the native asphalt bitumens that were used in laying your original asphalt surface. If oxidation is too severe, the asphalt will start to become rigid and crack. Sealcoating may initially fill these cracks but the solids in sealer have no strength characteristics like crack filler. In the case where there are distressed areas or widespread cracking there may be other options recommended such as repair, overlay / resurfacing, or crackfilling.

The sealcoating business has a low entry point for inexperienced contractors to start a business and as a result many commercial applications vary considerable in quality. This is due to a number of reasons including lack of experience and a high incidence of cutting the product with more water than the manufacturer recommends in order to increase yield. Hire a reputable contractor that stands behind their work and has the necessary resources to get your parking lot done in a timely manner.

We work with the customer to plan phasing to minimize the impact of sealcoating and repair activities on your place of business. Our years of experience and know how will help to make the process as painless as possible.
