How Much Does It Cost to Seal a Driveway in Construction?
Sealing a driveway is one of the most effective ways to protect, enhance, and extend the life of a driveway. In construction and residential maintenance, driveway sealing is often recommended after paving to guard against weathering, oil spills, and cracking. But a common question homeowners and property managers ask is: How much does it cost to seal a driveway?
The answer depends on multiple factors such as driveway size, material, sealing method, and whether you hire a professional or go the DIY route. Below, we’ll break down everything you need to know about driveway sealing costs in construction projects.
What is Driveway Sealing?
Driveway sealing involves applying a protective layer of sealant over asphalt or concrete driveways. This sealant acts as a barrier against water, UV rays, oil, and salt damage. In construction, sealing is often the finishing touch after paving, ensuring durability and reducing long-term repair costs.
Average Cost to Seal a Driveway
On average, the cost to seal a driveway ranges between $0.15 and $0.40 per square foot for DIY projects and $0.50 to $1.50 per square foot when hiring professionals.
- Typical residential driveway (600–800 sq. ft.)
- DIY: $90 – $320
- Professional: $300 – $1,200
- Larger driveways (1,000–2,000 sq. ft.)
- DIY: $150 – $800
- Professional: $500 – $3,000
Factors That Affect Driveway Sealing Costs
1. Driveway Size
Larger driveways cost more because of increased sealant use and labor time.
2. Driveway Material
- Asphalt driveways: Cheaper to seal, requiring standard asphalt emulsion or coal tar sealers.
- Concrete driveways: More expensive; require special acrylic or epoxy-based sealers.
3. Type of Sealant
- Coal tar sealer: $0.15–$0.25 per sq. ft. (durable but less eco-friendly).
- Asphalt emulsion sealer: $0.20–$0.40 per sq. ft. (environmentally friendly).
- Acrylic/epoxy sealers: $0.50–$1.00 per sq. ft. (often for concrete).
4. Labor Costs
Professional contractors charge $0.50 to $1.50 per sq. ft. depending on location and driveway condition.
5. Repairs Before Sealing
If cracks or potholes need repair before sealing, add $100–$500 to the total project cost.
6. Geographic Location
Urban areas with higher labor costs typically see higher sealing rates than rural areas.
DIY vs. Professional Driveway Sealing
| Option | Cost | Pros | Cons |
|---|---|---|---|
| DIY Sealing | $0.15 – $0.40 per sq. ft. | Cheaper, flexible schedule, small-scale jobs | Time-consuming, less durable finish |
| Professional | $0.50 – $1.50 per sq. ft. | High-quality finish, faster completion, warranty | Higher upfront cost |
When Should You Seal a Driveway?
- New asphalt driveways: Wait 6–12 months before sealing.
- Concrete driveways: Can be sealed once fully cured (usually 30 days).
- Resealing: Every 2–3 years for asphalt, and every 3–5 years for concrete, depending on wear and climate.
Benefits of Sealing a Driveway
- Protects against water penetration and freeze-thaw damage.
- Prevents oxidation from sun exposure.
- Enhances appearance with a clean, dark finish.
- Increases lifespan of the driveway.
- Reduces maintenance costs in the long run.
Conclusion
The cost to seal a driveway in construction depends on driveway size, material, sealer type, and labor. While DIY sealing can be affordable at around $0.15–$0.40 per sq. ft., professional services provide a more durable finish for $0.50–$1.50 per sq. ft.. Considering that sealing protects your investment, prevents costly repairs, and improves curb appeal, it’s a small price to pay for long-term durability.
