What Proper Seal Coating Does

Your driveway stops looking like it’s aging out of your neighborhood. That faded, cracked asphalt gets a fresh black finish that makes your property look maintained and cared for.

More importantly, you’re buying time. Quality seal coating creates a waterproof barrier that keeps moisture from seeping into cracks and causing the freeze-thaw damage that turns small problems into expensive ones. You’re looking at extending your asphalt’s lifespan by years, not months.

The protection goes beyond water. Oil stains from cars, salt from winter, and UV rays from Long Island summers all break down unprotected asphalt. A proper sealcoat stops that deterioration before it starts, keeping your surface flexible and intact instead of brittle and crumbling.

Middle Island Sealcoating Company

We Know Long Island Asphalt

All Purpose Paving has been handling asphalt maintenance across Long Island for years, and we understand what Middle Island properties face. The salt air, the freeze-thaw cycles, the summer heat—it all takes a toll on your surfaces.

We’re not the crew that shows up, slaps on whatever’s cheapest, and disappears. We use commercial-grade sealants that actually hold up to Northeast weather, and we time applications around conditions that matter—temperature, humidity, and forecast.

You’ll work with the same local team from estimate to completion. We’re licensed, insured, and we live in the area, so our reputation matters to us long after your driveway dries.

Asphalt Sealing Process

Here's How We Handle It

First, we clean your asphalt thoroughly. That means removing debris, treating oil stains, and making sure the surface is ready to accept the sealant. Skipping this step is where most jobs fail—sealant won’t bond properly to dirty or contaminated asphalt.

Next comes crack filling if needed. We address any cracks larger than hairline before sealing because sealing over damaged areas just hides problems temporarily. You want repairs that actually fix things.

Then we apply the sealcoat using professional equipment that ensures even coverage. We’re not painting with brushes here—proper application requires the right tools and technique to avoid streaks, puddles, or thin spots that fail early.

Finally, we protect the fresh surface during curing. That means barriers to keep traffic off until it’s fully dry, usually 24-48 hours depending on weather. You get clear instructions about when it’s safe to use your driveway again.

What's Included in Every Job

Every seal coating job includes thorough surface preparation, crack filling for cracks up to a quarter-inch, and two-coat application of commercial-grade sealant. We’re not cutting corners with single coats that look good for six months then start failing.

You also get edge work around your entire driveway perimeter. Those edges where asphalt meets grass or concrete are where water infiltration usually starts, so we make sure they’re properly sealed and protected.

We handle cleanup completely. Your landscaping, walkways, and garage floor don’t get sealant overspray because we take time to mask properly. When we’re done, the only thing that looks different is your freshly sealed driveway.

Weather delays don’t cost you extra. Long Island weather changes fast, and we’d rather reschedule than apply sealcoat in conditions that compromise the job. You want it done right, not just done quickly.

How often should I seal coat my driveway in Middle Island?

Most residential driveways in Middle Island need seal coating every 2-3 years, but it depends on traffic and exposure. A driveway that sees heavy use or gets full sun all day might need attention every other year, while a lightly used driveway in partial shade can often go three years between applications. The key indicator is color—when your asphalt starts looking gray instead of black, it’s time. Don’t wait until you see significant cracking because by then you’re dealing with repairs, not just maintenance.

What's the best time of year for seal coating on Long Island?

Late spring through early fall gives you the best conditions—specifically when temperatures stay above 50 degrees for at least 48 hours after application. We typically see the ideal window from May through September, avoiding the hottest summer days when sealant can dry too quickly. Weather matters more than calendar dates, though. We need dry conditions with no rain in the forecast for at least 24 hours after application, and humidity levels that allow proper curing. That’s why we stay flexible with scheduling and don’t lock you into dates weeks in advance.

Can you seal coat over existing cracks and damage?

Small cracks, yes—we fill them as part of the prep work. But sealcoating isn’t a magic fix for serious damage. Cracks wider than a quarter-inch, areas where the asphalt is crumbling, or sections with significant settling need repair before sealing. Think of sealcoat as sunscreen, not surgery. It prevents damage but can’t reverse it. We’ll be honest during the estimate about what needs repair work first. Sealing over major damage just wastes your money because the problems will show through within months.

How long before I can drive on freshly sealed asphalt?

Plan on 24-48 hours before driving on it, depending on temperature and humidity. Cooler, humid conditions take longer to cure. We’ll give you specific timing based on weather conditions during your job, but rushing this step ruins everything. Sealcoat that gets tire marks or indentations before it’s fully cured looks terrible and performs poorly. We recommend having an alternate parking plan ready, especially if rain is possible. Light foot traffic is usually okay after 4-6 hours, but no vehicles until we give the all-clear.

What's the difference between different types of sealcoat materials?

The main choice is between coal tar and asphalt-based sealers. Coal tar offers better protection against gas and oil stains, plus it tends to last longer in our climate. Asphalt-based sealers are more environmentally friendly and still provide good protection for most residential driveways. We typically recommend coal tar for driveways that see oil leaks or heavy use, and asphalt-based for standard residential applications. Both work well when applied properly—the application quality matters more than the specific product in most cases.

Do I need to do anything to prepare my driveway before you arrive?

Move all vehicles, bikes, and anything else off the driveway and keep it clear for the entire curing period. Sweep off loose debris if you want, but don’t pressure wash or use cleaning chemicals—we handle all the surface prep with appropriate products. Make sure we have water access for cleanup, and let us know about any sprinkler systems or drainage issues we should know about. If you have pets, plan to keep them away from the area during application and curing. That’s really it—we bring everything else needed for the job.
