What Is Asphalt Sealcoating?
Asphalt sealcoating is a protective layer applied over your existing asphalt surface. Think of it like sunscreen for your driveway. It blocks out UV rays, seals the surface from water intrusion, and slows down the natural aging process.
In the Pacific Northwest, that protection matters. Between rain, temperature swings, and moss growth, unprotected asphalt breaks down faster than most homeowners expect.
Sealcoating doesn’t fix major damage, but it does:
- Protect healthy asphalt from early deterioration
- Restore that clean, black finish
- Extend the usable life of your driveway
- Reduce long-term repair costs
If your driveway is still structurally sound, sealcoating is one of the smartest preventative steps you can take. If you’re wondering what is asphalt sealcoating and whether it’s worth the investment, understanding how it protects asphalt from moisture, UV damage, and oxidation can help you make an informed decision.

How We Apply Sealcoat the Right Way
Not all sealcoating jobs are created equal. When it’s done right, sealcoating does more than just darken your driveway, it adds a layer of real protection.
Here’s what we focus on every time we apply a sealcoat:
Full Surface Protection: We use high-quality, weather-appropriate sealants designed to handle the Pacific Northwest climate. No watered-down mix, no quick-dry gimmicks.
Proper Prep, Every Time: We clean and edge the surface, fill visible cracks, and wait for dry conditions. Skipping this step leads to early failure, and we don’t cut corners.
Clean, Even Finish: You won’t find streaks, puddles, or tar overspray in your lawn. Just a smooth, professional coat that enhances curb appeal and surface integrity.
Long-Term Value: A proper sealcoat can extend the life of your asphalt by three to five years. That’s time and money saved on full replacement down the road.

Asphalt Resurfacing vs Sealcoating
Sometimes homeowners aren’t sure whether to sealcoat or resurface. Sealcoating is a protective layer for healthy asphalt, it prevents water, sun, and wear from damaging your surface. Resurfacing, on the other hand, involves adding a new layer of asphalt to correct surface-level damage. If your driveway has minor cracks or fading, sealcoating is the cost-effective preventative step. If it has deeper cracks, uneven areas, or previous damage, resurfacing may be necessary first, or combined with sealcoating for long-term durability.
