Asphalt Sealcoating Essentials: Understanding the Process and Cost Factors

Asphalt, renowned for its versatility and strength, serves as a cornerstone in the construction of roads, driveways, and parking lots. However, despite its resilience, asphalt is susceptible to wear and deterioration over time due to continuous exposure to various environmental factors. To counteract these challenges, consistent maintenance becomes imperative to preserve the asphalt’s durability and extend its lifespan. One fundamental practice that stands out among the arsenal of asphalt maintenance techniques is asphalt sealcoating. 


What is Asphalt Sealcoating?

Sealcoating involves the application of a protective layer of sealer onto the surface of the asphalt. This layer acts as a robust shield, safeguarding the pavement against a multitude of detrimental elements.

First and foremost, sealcoating shields the asphalt from the damaging effects of ultraviolet (UV) rays emitted by the sun. Prolonged exposure to UV rays leads to the oxidation of asphalt, causing it to become brittle and susceptible to cracking. By applying a sealant, the asphalt is shielded from these harmful rays, preventing premature aging and maintaining its structural integrity.

Sealcoating also creates a barrier that effectively repels water penetration. Water poses a significant threat to asphalt because it can seep into its porous structure, leading to the formation of cracks, potholes, and other forms of pavement damage. The protective layer of sealant acts as a waterproofing agent, preventing water from infiltrating the asphalt and minimizing the risk of moisture-related deterioration.

Additionally, sealcoating provides a defense against oil spills and leaks, commonly encountered in driveways and parking lots. The sealant acts as a resistant barrier, preventing oil and other automotive fluids from seeping into the asphalt and causing structural damage. By repelling these substances, sealcoating helps maintain the integrity of the pavement and reduces the likelihood of costly repairs.

Furthermore, sealcoating serves as an effective measure against oxidation. When asphalt is exposed to oxygen over time, it undergoes a chemical reaction that results in oxidation, causing the pavement to lose its flexibility and become prone to cracks and surface deterioration. By applying a sealant, sealcoating inhibits the oxidation process, keeping the asphalt flexible, resilient, and less susceptible to damage.


Asphalt sealcoating acts as a shield, offering comprehensive protection against harmful elements that can compromise the integrity and lifespan of asphalt pavement. By protecting the surface against UV rays, water penetration, oil spills, and oxidation, sealcoating ensures that your asphalt infrastructure remains durable, functional, and visually appealing for years to come.

Asphalt Sealcoating Cost Considerations:

The cost of asphalt sealcoating is influenced by multiple factors that contribute to its variability. These factors include the size of the area requiring sealing, the condition of the pavement, and the prevailing market rates in your locality. Generally, sealcoating can range anywhere from $0.15 to $1.50 or more per square foot, depending on these considerations.

At first glance, the cost of sealcoating might appear as an additional expense, leading some to question its value. However, it is crucial to recognize that sealcoating is not just an expenditure but rather an investment in the longevity and maintenance of your asphalt infrastructure.

By opting for sealcoating, you are proactively protecting your pavement against the harsh effects of time and external elements. The relatively modest upfront cost of sealcoating pales in comparison to the potential expenses associated with extensive repairs or premature resurfacing. In essence, sealcoating acts as a preventive measure, mitigating the need for more costly repairs and preserving the structural integrity of your asphalt.

Don’t think of asphalt sealcoating as an expense—it is a wise investment in the durability, appearance, and long-term cost savings of your asphalt infrastructure. By protecting your pavement from harmful elements and minimizing the need for extensive repairs, sealcoating ensures that your asphalt continues to serve you reliably for years to come.

Frequency of Asphalt Sealcoating:

The optimal frequency for sealcoating your asphalt depends on a variety of factors that directly impact its wear and tear. Factors such as climate, traffic volume, and the present condition of the pavement all play a role in determining when sealcoating should be performed. While a general guideline suggests reapplication every two to three years, it’s important to note that certain circumstances may necessitate more frequent sealcoating to ensure maximum protection and longevity for your asphalt.

One of the primary factors to consider is the climate in your region. Extreme weather conditions, such as scorching heat, bitter cold, heavy rainfall, or snowfall, can accelerate the deterioration of asphalt. The constant exposure to these elements can cause the asphalt to expand and contract, leading to cracks and potholes. In areas with harsh climates, it may be advisable to schedule sealcoating more frequently to create an additional barrier against these weather-related damages.

Traffic volume is another crucial factor influencing the frequency of sealcoating. High-traffic areas, such as commercial parking lots or busy roadways, subject the asphalt to constant stress from vehicles, including heavy trucks and frequent turning movements. The repeated pressure and friction can gradually wear down the surface of the asphalt, making it more susceptible to cracks and deterioration. In such cases, sealcoating should be performed more frequently to provide a robust protective layer that can withstand heavy use.

Regular inspections conducted by professionals are instrumental in determining the optimal timeframe for sealcoating reapplication. These inspections allow experts to assess the condition of your pavement, identify signs of wear and tear, and make informed recommendations regarding sealcoating maintenance. By engaging the services of experienced professionals, you can benefit from their expertise and knowledge, ensuring that your sealcoating schedule is tailored to the unique characteristics of your asphalt and the specific demands it faces.
