Professional Seal Coating Long Island, NY

Your Driveway Faces a Beating Every Single Year

Long Island’s freeze-thaw cycles, coastal salt air, and scorching summer sun don’t just fade your asphalt—they break it down from the inside out. Water seeps into tiny cracks, freezes, expands, and creates the potholes that cost thousands to fix. Asphalt seal coating creates a protective barrier that blocks moisture, UV rays, oil, and chemicals before they can damage your driveway. It’s not a repair—it’s prevention. And when applied every two to three years by a licensed crew, it can double the lifespan of your asphalt while keeping it looking sharp. CPR Power Washing brings professional seal coating to homeowners across Suffolk & Nassau County, NY who want their driveway protected the right way, by people who actually show up and stand behind their work.

Asphalt Maintenance Suffolk & Nassau County, NY

Long Island Weather Destroys Unprotected Asphalt

You’ve seen it happen. A driveway looks fine in spring, then by fall there are new cracks spreading like spiderwebs. By the next winter, those cracks are potholes. That’s because asphalt is porous. When water gets in and freezes, it expands with enough force to break apart the pavement. Add in UV rays that dry out the binder, salt that accelerates deterioration, and oil stains that soften the surface, and you’re looking at a driveway that ages in dog years. Seal coating stops this cycle. It fills surface voids, creates a waterproof barrier, and blocks the UV rays that make asphalt brittle. The dark finish also retains heat, which helps melt snow and ice faster—something every Long Island homeowner appreciates come January. Most driveways should be seal coated every two to three years. Wait longer than that and you’re not just losing curb appeal you’re losing structural integrity. And once the base layer starts failing, you’re not seal coating anymore. You’re repaving.

Crack Sealing and Pothole Repair in Suffolk & Nassau County, NY

Seal Coating Works Best When Cracks Get Fixed First

Seal coating isn’t a repair. It’s a protective layer. If your driveway already has cracks wider than a quarter-inch or small potholes forming, those need to be addressed before we seal. That’s where crack sealing and pothole repair come in. We clean out the damaged areas, fill them with hot rubberized material or asphalt patching compound, and compact everything down so it bonds with the existing surface. Once that’s cured, the seal coat goes on top and locks everything in place. This is one of the reasons homeowners choose us—we handle the whole process. You don’t need one contractor to fix cracks, another to power wash, and a third to seal. We show up, assess what needs attention, and take care of it in one visit. It’s faster. It’s cleaner. And you’re not playing phone tag with three different people trying to schedule around each other.

Asphalt Seal Coating FAQs

Common Questions About Our Service

How often should I seal coat my asphalt driveway in Long Island?

Every two to three years is the standard recommendation for residential driveways in climates like Long Island. If your driveway sees heavy use, is in direct sunlight most of the day, or you’re noticing fading and small cracks, lean toward every two years. The key is not waiting too long—once the asphalt starts breaking down structurally, seal coating can’t fix it. At that point, you’re looking at resurfacing or replacement, which costs significantly more. Regular seal coating is preventative maintenance that saves you from those bigger bills down the road.

How much does asphalt seal coating cost in Suffolk or Nassau County?

Professional seal coating typically runs between $0.15 and $0.25 per square foot, depending on the condition of your driveway and whether you need crack sealing or repairs first. For a standard two-car driveway, you’re usually looking at a few hundred dollars. Compare that to $3 to $5 per square foot for a full repaving job, and you can see why seal coating every few years makes financial sense. We provide upfront estimates with no surprises, so you know exactly what you’re paying before we start. If you need additional services like power washing or pothole repair, we’ll bundle those into one clear quote.

Can you seal coat my driveway if it already has cracks?

Yes, but we need to fix those cracks first. Seal coating is a protective layer—it won’t fill or repair structural damage. Small cracks get filled with hot rubberized crack filler, and any potholes or deeper damage get patched with asphalt repair material. Once those repairs are done and cured, we apply the seal coat over the entire surface. This locks everything in place and prevents new water infiltration. If your driveway has extensive cracking or alligator patterns, we’ll let you know upfront if seal coating is still the right solution or if you’re better off resurfacing.

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

Late spring through early fall is ideal—basically May through September on Long Island. You need consistent temperatures above 50°F and dry conditions for at least 24 to 48 hours after application. The sealer needs time to cure properly, and rain or cold temps will interfere with that process. Summer is popular because the weather is predictable, but early fall works great too. We don’t recommend seal coating in winter or early spring when freeze-thaw cycles are still happening. If you’re planning ahead, reach out in spring to get on the schedule before the busy season fills up.

How long does seal coating last on a driveway?

A quality seal coat typically lasts two to three years before it starts showing wear. You’ll notice the finish beginning to fade or lose that deep black color—that’s your signal it’s time to reseal. How long it lasts depends on a few factors: traffic volume, sun exposure, weather conditions, and whether the driveway was properly prepped before sealing. Driveways in full sun or with heavy vehicle traffic may need resealing closer to the two-year mark. Shaded driveways with lighter use can stretch to three years or slightly beyond. The good news is that regular seal coating compounds over time, keeping your asphalt in better shape with each application.

Do I need to stay off my driveway after it's seal coated?

Yes, you’ll need to keep vehicles off for at least 24 to 48 hours, depending on weather conditions. Warm, dry weather helps the sealer cure faster. We’ll let you know the exact timeline when we finish the job. You can walk on it sooner—usually after a few hours—but avoid dragging anything heavy across the surface. If it’s hot out, the sealer stays softer longer, so give it the full 48 hours to be safe. We’ll also recommend keeping sharp objects like bike kickstands off the fresh seal coat for the first week or so. It’s a small inconvenience for protection that lasts years.
