Your Asphalt Gets Real Protection

You’re looking at cracked, faded asphalt that’s making your property look tired. Every season without protection means more water seeping in, more freeze-thaw damage, and bigger repair bills down the road.

Seal coating creates a protective barrier that blocks water, UV rays, and the harsh Long Island weather that’s beating up your driveway. You get a smooth, deep black finish that makes your property look maintained and cared for.

The real benefit isn’t just appearance—it’s time and money. Properly sealed asphalt lasts 3-5 years longer before needing major repairs. That’s thousands of dollars you keep in your pocket instead of spending on premature repaving.

Greenlawn Asphalt Sealing Experts

We Know Long Island Asphalt

We’ve been protecting driveways and parking lots across Greenlawn and Long Island for years. We understand what the coastal humidity, winter salt, and temperature swings do to your asphalt.

You’re not getting a fly-by-night crew or someone learning on your driveway. We use commercial-grade sealers and proper equipment because we’ve seen what happens when corners get cut.

Every job starts with real surface preparation—cleaning, crack filling, and making sure the sealer actually bonds to your asphalt instead of just sitting on top.

Our Sealcoating Process

Here's Exactly What Happens

First, we clean your asphalt completely—removing dirt, debris, and any loose material that would prevent proper adhesion. This isn’t a quick sweep; we’re talking about thorough preparation that most companies skip.

Next, we fill any cracks and repair problem areas. Sealer over unfilled cracks is wasted sealer. We address the underlying issues first so your coating actually protects instead of just covering up problems.

Then we apply the sealer using professional equipment that ensures even coverage and proper thickness. We work in sections, maintaining wet edges to avoid lap marks or thin spots. The whole process typically takes a day, depending on your driveway size, with 24-48 hours drying time before you can drive on it.

What You Get With Every Job

Your seal coating service includes thorough surface cleaning, crack filling for cracks up to a quarter-inch wide, and two coats of commercial-grade sealer applied with professional equipment. We’re not using hardware store buckets and squeegees.

We only work in proper weather conditions—no rain in the forecast, temperatures above 50 degrees, and low humidity. Rushing the job in poor conditions ruins the results, so we schedule based on weather, not just your availability.

You’ll know exactly when we’re coming and what to expect. We protect landscaping, move any obstacles, and clean up completely when we’re done. Your driveway will be clearly marked with cones or tape, and we’ll give you specific instructions about when it’s safe to walk or drive on the fresh sealer.

How long does seal coating last on a driveway?

Quality seal coating typically lasts 2-3 years in Long Island’s climate, depending on traffic and weather exposure. Driveways with heavy use or full sun exposure may need resealing closer to the 2-year mark, while protected driveways in good condition can go 3-4 years. The key is using commercial-grade sealer and proper application—cheap sealer starts failing within a year. We use materials designed for our climate, not generic products that can’t handle the temperature swings and moisture we get here.

What's the best time of year to seal coat asphalt?

Late spring through early fall works best—basically May through October when temperatures stay consistently above 50 degrees and humidity is manageable. We avoid sealing during the hottest summer days when sealer can dry too quickly, and obviously winter is out because sealer won’t cure properly in cold weather. The ideal conditions are mild temperatures, low humidity, and no rain for 24-48 hours after application. We track weather forecasts carefully and will reschedule if conditions aren’t right, because rushing the job in poor weather ruins the results.

Should I fill cracks before applying sealer?

Absolutely. Sealer over unfilled cracks is basically throwing money away—the cracks will continue expanding and the sealer will fail at those points first. We fill cracks up to a quarter-inch wide as part of our standard service using rubberized crack filler that moves with the asphalt. Larger cracks or structural issues need proper repair before sealing. Think of it this way: sealer protects good asphalt, but it won’t fix broken asphalt. Proper crack filling ensures the sealer can do its job of preventing water infiltration and further damage.

How long before I can drive on freshly sealed asphalt?

Plan on 24-48 hours before driving on it, depending on temperature and humidity. Hot, dry weather means faster curing; cool, humid conditions take longer. We’ll give you specific timing based on the weather when we do your job. You can usually walk on it after 4-6 hours, but avoid dragging anything across the surface. The sealer may feel dry to the touch but still be soft underneath. Driving on it too early leaves tire marks and can pull up the sealer, ruining the job. We’d rather have you wait an extra day than redo the work.

What happens if it rains after seal coating?

If it rains before the sealer cures completely, it can wash away or damage the coating, which is why we check weather forecasts carefully before starting any job. Light rain after 8-12 hours usually won’t cause major problems, but heavy rain within the first few hours can ruin the application. This is why we don’t take chances with questionable weather—we’d rather reschedule than have to redo the work. If unexpected weather does damage a fresh application, we’ll assess the damage and make it right. That’s part of doing the job professionally.

How much does professional seal coating cost?

Most residential driveways in Greenlawn run between $200-600 depending on size, condition, and prep work needed. Parking lots and commercial jobs are priced by square footage. The variation comes from surface preparation requirements—a well-maintained driveway needs less prep than one with multiple cracks and stains. We provide written estimates that break down exactly what’s included so you know what you’re paying for. Remember, cheap seal coating usually means shortcuts on materials or preparation, which shows up as early failure and the need to redo the work sooner.
