Cost to Seal Driveway in Construction: A Complete Guide
A driveway is more than just a functional entryway—it’s also a key part of a property’s curb appeal. Over time, exposure to sun, rain, snow, and vehicle traffic can wear down driveway surfaces, leading to cracks, discoloration, and reduced durability. Sealing a driveway is a cost-effective solution to protect and extend its lifespan. For homeowners, contractors, and property developers, understanding the cost to seal a driveway in construction projects is crucial when budgeting and planning.
This article explores the average costs, factors affecting pricing, types of sealants, and why sealing should be considered a necessary step in both residential and commercial construction.
Why Seal a Driveway?
Driveway sealing is the process of applying a protective coating over asphalt or concrete to guard against damage. Here’s why it’s important:
- Protection Against Weather: Prevents water penetration and freeze-thaw cycles that cause cracks.
- Enhanced Appearance: Restores the driveway’s dark, clean look.
- Longevity: Extends the life of asphalt or concrete by several years.
- Cost Savings: Reduces the need for costly repairs or replacements.
- Resistance to Chemicals: Protects against oil, gas, and salt damage.

Types of Driveway Sealants
- Coal Tar-Based Sealants: Affordable but less eco-friendly; durable against oil and gas.
- Asphalt-Based Sealants: More environmentally friendly, flexible, and safe.
- Acrylic Sealants: Long-lasting, UV-resistant, but higher in cost.
