How Much Does Residential Sealcoating Cost in Raleigh, NC?
We get that starting a home project can feel a bit overwhelming, especially if you’re unsure about making a commitment. It’s not always easy to jump into a decision when you’re not completely ready. That’s why we want to make things easier by giving you a simple guide to costs and materials, so you can see what to expect before moving forward.
So far we all agree that sealcoating is an essential step in preserving your asphalt driveway, protecting it from weather damage, UV rays, and wear from everyday use. If you’re a homeowner in Raleigh or its surrounding areas, understanding the pricing for residential sealcoating is crucial, especially when considering the cost per square foot. This guide will break down the typical pricing structure, materials used, and real-time costs to give you a clear idea of what to expect.
How Sealcoating Costs are Calculated
The price of sealcoating a residential driveway typically depends on several factors, including the size of the driveway, the type of sealant used, and the current condition of the asphalt. In North Carolina, the average cost for sealcoating ranges between $0.15 to $0.30 per square foot, but there are a few variables that can influence this range.
Driveway Size: The larger your driveway, the lower the cost per square foot. Sealcoating companies often offer bulk pricing for bigger projects, so a larger driveway could bring the cost per square foot down.
Asphalt Condition: If your driveway has numerous cracks, holes, or other damage, pre-repair work such as crack filling may be needed, which can increase the total cost. Expect to pay extra if repairs are needed before the sealcoat can be applied.
Type of Sealant: Not all sealcoating materials are created equal. Higher-quality sealants, such as coal tar or asphalt emulsion, may cost more but offer superior protection and longevity. We do not use Sealing Products from the Big Box Stores.
Real-Time Material Costs for Sealcoating in NC
Here’s a breakdown of common materials used in sealcoating and their current costs in North Carolina:
Coal Tar Sealant: This durable, weather-resistant sealant is a popular choice for residential driveways. The average cost for coal tar emulsion is $10 to $15 per gallon, and it typically covers around 100 square feet per gallon, which makes it affordable and long-lasting.
Asphalt Emulsion Sealant: Known for being more eco-friendly, asphalt emulsion is another widely used material. It’s slightly more expensive at $12 to $18 per gallon and covers roughly the same area as coal tar. Asphalt emulsion is less toxic and emits fewer fumes, which is a plus for many homeowners.
Additives: Many sealcoating jobs include additives like sand or polymers to enhance durability and skid resistance. These can increase costs by about $0.02 to $0.05 per square foot, depending on the level of durability required.
Crack Filler: Before sealcoating, cracks must be filled to ensure a smooth, even surface. Crack filler typically costs $1 to $3 per linear foot, depending on the severity of the cracks.
Driveway Size: The larger your driveway, the lower the cost per square foot. Sealcoating companies often offer bulk pricing for bigger projects, so a larger driveway could bring the cost per square foot down. This is also why Commercial Sealcoating Projects tend to cost less on average by the sq. ft.
Asphalt Condition: If your driveway has numerous cracks, holes, or other damage, pre-repair work such as crack filling may be needed, which can increase the total cost. Expect to pay extra if repairs are needed before the sealcoat can be applied.
Type of Sealant: Not all sealcoating materials are created equal. Higher-quality sealants, such as coal tar or asphalt emulsion, may cost more but offer superior protection and longevity.

Additional Costs to Consider
While the per-square-foot cost of sealcoating is relatively affordable, there may be additional expenses depending on the complexity of the job:
Cleaning and Prep Work: Before applying the sealant, the surface needs to be thoroughly cleaned to remove dirt, oil, and debris. This could add around $0.05 to $0.10 per square foot.
Edge Work: Applying sealcoat near landscaping or hard-to-reach areas can increase labor costs. Edge work usually adds $0.02 to $0.05 per square foot.
Weather Conditions: (This is critical!) Sealcoating is best done during mild, dry weather, typically in spring or early fall. If weather delays occur, they may add to the overall project time and potentially increase labor costs.
So, after all that, you may find yourself wondering: Is It Worth It?
Well, Asphalt Maintenance is our business, and honestly, while it may seem like an extra cost, sealcoating your driveway is a smart investment in the long run.
