When Should You Sealcoat?
Sealcoating is the single best-value maintenance service for asphalt — protecting against UV oxidation, water infiltration, and fuel spills.
| Surface / Climate | Recommended Frequency |
|---|---|
| Residential driveway — moderate climate | Every 3–5 years |
| Residential driveway — hot/sunny (AZ, NV, FL) | Every 1–2 years |
| Commercial parking lot — moderate climate | Every 3–4 years |
| Commercial parking lot — harsh winters (MN, WI) | Every 2–3 years |
| High UV / desert markets (Phoenix, Las Vegas) | Every 1–2 years |
| New asphalt (first application) | Wait 6–12 months, then seal |
Prevents oxidation
UV radiation breaks down asphalt binder, causing graying and surface raveling. Sealcoating blocks UV and extends pavement life 2–3x.
Blocks water infiltration
Water entering cracks freezes, expands, and widens damage rapidly. Sealcoating closes surface pores and slows this process.
Cost vs. replacement
Sealcoating costs $0.15–$0.45/sq ft. Full resurfacing costs $2–$6/sq ft. Regular sealing is 10–20x cheaper than premature replacement.

Frequently Asked Questions
How much does sealcoating cost per square foot?▼
Sealcoating costs $0.14–$0.45 per square foot depending on surface type, number of coats, and region. Two coats are recommended for commercial lots and driveways. Larger jobs cost less per sq ft due to mobilization efficiency.
How much does it cost to sealcoat a parking lot?▼
A 10,000 sq ft parking lot costs approximately $1,400–$3,500 for sealcoating (2 coats). A 30,000 sq ft lot runs $4,200–$10,500. Add crack sealing for another $500–$2,000 depending on the extent of cracking.
How long does sealcoating last?▼
A quality 2-coat sealcoating application lasts 3–5 years in moderate climates, 1–3 years in hot, sunny markets like Arizona and Nevada. Traffic volume and weather exposure are the primary factors affecting longevity.
Can you sealcoat a driveway yourself?▼
DIY sealcoating is possible with squeegee-applied products from hardware stores. Professional results require commercial-grade coal-free sealer, proper surface cleaning, crack filling, and temperature/humidity conditions. For driveways over 1,000 sq ft, professional application typically delivers better results and longevity.
