Why Sealcoat Your Driveway?

Extend the life of your asphalt

Sealcoating isn’t just cosmetic. It’s a protective barrier that keeps your driveway safe from damaging elements like water, chemicals, oil, and UV rays. Left untreated, asphalt will start to break down—leading to cracks and potholes that get worse with time.

Applying a sealcoat every two to three years can more than double the lifespan of your driveway. It’s a simple and affordable way to protect one of the most visible features of your home.

Prevent Damage Before It Starts

Affordable prevention that saves in the long run

Replacing a damaged asphalt driveway can cost thousands of dollars. But keeping it in good shape doesn’t have to. Sealcoating creates a waterproof, weather-resistant layer that protects against rain, sun, and chemicals—reducing the risk of surface breakdown and costly repairs.

Regular sealcoating also slows down oxidation. Asphalt naturally fades and becomes brittle over time, especially under constant exposure to sunlight. A fresh sealcoat blocks UV rays, helping your driveway stay flexible, smooth, and dark in color for years to come.

Improve the Appearance of Your Home

Restore that clean blacktop look

Over time, driveways fade to gray, often looking tired and worn out even if they’re still functional. Sealcoating brings back the deep, rich black finish of freshly laid asphalt, instantly boosting your home’s curb appeal.
Whether you’re planning to sell your home or just want it to look its best, a properly sealed driveway adds a clean, polished look to your property.

The William Stanley & Sons Sealcoating Process

Professional work done the right way

At William Stanley & Sons Paving, we follow a careful, proven process to ensure every sealcoating job delivers lasting protection and great results. We don’t cut corners, and we don’t rush the job. Every step is handled by experienced professionals who understand how to sealcoat your driveway the right way.

Here’s what our typical process looks like:

  • First, we clean the surface thoroughly using power blowers and brooms to remove all dirt and debris.
  • Next, we inspect for any existing damage. If there are cracks, we use crack filler to repair and seal them before applying the sealcoat.
  • We then apply a high-quality commercial-grade sealant, typically in two coats, for even coverage and maximum protection.
  • After application, the sealcoat needs time to cure. We recommend keeping vehicles off the driveway for at least 24 hours while it dries.

We’ll always walk through the project with you when the work is complete to make sure everything looks exactly as it should.

When Should You Sealcoat?

Know the signs it’s time to re-seal

If your driveway is fading in color, starting to develop hairline cracks, or looking rough and uneven, it’s probably time to apply a new sealcoat. We recommend sealing your driveway every two to three years depending on traffic levels and weather exposure.

Even if your driveway is relatively new, sealing it early on can keep it protected and looking sharp for the long haul. The sooner you start with preventative maintenance, the longer your driveway will last without major issues.

Don’t Wait for Damage to Spread

Protect your investment today

Once small cracks begin to appear, water can get in and do real damage—especially during freeze-thaw cycles in colder months. Cracks and potholes don’t fix themselves, and the longer you wait, the more expensive the repair can become.

With William Stanley & Sons, you get a trusted team that knows how to keep your pavement in top condition. We use the best materials, apply the right techniques, and treat every home like it’s our own.

FAQs About Driveway Seacoating

What exactly is driveway sealcoating?

Sealcoating is a protective liquid layer applied over your asphalt driveway. It shields the surface from water, sun, oil, and other damaging elements—helping your driveway last longer and look better over time.

How long does sealcoating take to dry?

We recommend allowing 24 hours for the sealcoat to fully cure. During that time, it’s best to keep vehicles and foot traffic off the driveway to ensure a smooth, even finish.

How often should I sealcoat my driveway?

Most homeowners seal their asphalt driveway every two to three years. If you notice fading, small cracks, or rough patches, it may be time to reapply the sealcoat sooner.

Will sealcoating fix cracks and potholes?

Sealcoating protects against future damage but doesn’t fix existing issues on its own. At William Stanley & Sons, we always apply crack filler and repair damaged areas before sealing to ensure a smooth, lasting result.

Why should I hire a professional for sealcoating?

Proper sealcoating takes experience, the right tools, and attention to detail. Our team knows how to seal coat your driveway the right way—giving you long-term protection without the mess or mistakes that come with DIY products.
