Sealing your driveway is a preventative maintenance measure that protects the asphalt or concrete surface from degradation due to weathering, chemicals, and UV radiation. This process extends the driveway's lifespan and improves its appearance.
Key Factors Influencing Sealing Costs
The total cost to seal a driveway is influenced by several variables:
- Driveway Size: This is the most significant factor. Costs are typically calculated per square foot. Larger driveways require more sealant and labor.
- Driveway Condition: Extensive cleaning, oil spot treatment, and repairs for cracks or potholes will add to the cost. A well-maintained driveway will be cheaper to seal.
- Type of Sealant: The quality and type of sealant impact the price. Options include:
- Asphalt Emulsion (water-based): Generally less expensive, easier to apply, and lower in VOCs.
- Coal Tar Emulsion: Highly durable and resistant to spills, but use is restricted in some areas due to environmental concerns.
- Acrylic (asphalt or petroleum-based): Offers enhanced durability, color retention, and a non-slip finish, but is typically more expensive.
- Polyurethane Sealers: Premium option offering superior protection and longevity, often the most costly.
- Labor Costs: Professional application will cost more than a DIY project. Labor rates vary by region and contractor experience.
- Number of Coats: Most driveways require one or two coats. Additional coats increase material and labor expenses.
- Preparation Work: Beyond cleaning and minor repairs, extensive edging or specific surface preparation can increase costs.
Estimated Cost Ranges
While prices vary, here are general estimates:
- DIY Project: Material costs for DIY sealing typically range from $0.15 to $0.50 per square foot. A 5-gallon pail of quality sealant might cost $25-$100, covering approximately 250-500 square feet with one coat. Additional costs for cleaning supplies and tools (squeegee, brushes) should be considered.
- Professional Sealing: Hiring a contractor generally costs between $0.75 to $2.50 per square foot. This price usually includes cleaning, minor crack filling, the sealant itself, and application. For an average two-car driveway (e.g., 600 sq ft), this could range from $450 to $1,500.
Note: Significant repairs, such as extensive crack filling or pothole patching, will incur additional charges beyond the basic sealing cost. It is advisable to get multiple quotes from reputable local contractors to obtain an accurate estimate for your specific driveway.
Regular driveway sealing, typically every 2 to 5 years depending on the sealant type and climate, is a cost-effective way to protect your investment and maintain your property's curb appeal.
