What Proper Seal Coating Does

Your asphalt faces a beating every day. Long Island’s weather throws everything at it – freezing winters, scorching summers, and that coastal salt that gets into every crack.

Seal coating creates a protective barrier that keeps water out, prevents oxidation, and stops small problems from becoming expensive ones. You’re looking at extending your pavement’s life by years, not months.

The difference is visible immediately. Fresh seal coating makes your driveway or parking lot look new again, but more importantly, it’s working underneath to prevent the kind of damage that leads to complete resurfacing jobs. That’s where the real value sits – in what you don’t have to pay for later.

Driveway Sealing Process Old Mastic

Here's How We Handle It

First, we clean your asphalt surface completely. Any oil stains, debris, or vegetation gets removed because sealant won’t bond properly to a dirty surface.

Next comes crack filling if needed. Small cracks get sealed before we apply the coating – this prevents water from getting underneath and causing bigger problems down the road.

Then we apply the sealcoat using professional-grade equipment. We’re not talking about the stuff you can buy at the hardware store. This is commercial-grade sealant that’s designed to handle Long Island’s weather conditions. The application goes on evenly, and we make sure to get proper coverage without leaving puddles or thin spots.

What's Included in Our Service

Every seal coating job includes complete surface preparation, crack filling for cracks under a quarter-inch, and two coats of premium sealant when conditions require it.

We handle both residential driveways and commercial parking lots. The process is the same, but commercial jobs often need additional attention to high-traffic areas and proper striping coordination.

You’ll get a clear timeline upfront. Weather affects curing time, so we’ll keep you informed if conditions push back your project. The last thing anyone wants is to rush a job and have it fail because we didn’t wait for proper drying conditions. In Old Mastic’s humid climate, patience pays off with better results.

How often should I seal coat my driveway in Old Mastic?

Most driveways in Old Mastic need seal coating every 2-3 years, but it depends on your specific conditions. High-traffic driveways or those exposed to a lot of sun might need attention sooner. The best indicator is the color – when your asphalt starts looking gray instead of black, it’s time to consider resealing. We can take a look and give you an honest assessment of where you stand.

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

Late spring through early fall works best for seal coating in our area. You need temperatures above 50 degrees and no rain in the forecast for at least 24 hours. Summer can be tricky because extreme heat makes application difficult, and you can’t walk or drive on fresh sealcoat until it’s fully cured. We typically recommend May, June, or September for the most reliable weather conditions.

How long does seal coating take to dry completely?

You can usually walk on sealed asphalt after 4-6 hours, but vehicles need to stay off for at least 24-48 hours depending on temperature and humidity. Long Island’s coastal humidity can extend drying times, especially in summer. We’ll give you specific timing based on the weather forecast for your project. Rushing this part ruins the job, so it’s worth waiting for complete curing.

Can you seal coat over cracks in my asphalt?

Small cracks get filled as part of our standard process, but larger cracks or areas with significant damage need repair work first. Seal coating over major cracks is like putting a band-aid on a broken bone – it might look better temporarily, but the problem will come back quickly. We’ll assess your asphalt condition and recommend crack repair if needed before applying any sealcoat.

How much does professional seal coating cost in Old Mastic?

Residential driveway seal coating typically runs between $0.15-$0.25 per square foot, depending on the condition of your asphalt and any prep work needed. Commercial parking lots have different pricing based on size and complexity. We provide written estimates with no hidden fees – what we quote is what you pay. The investment usually pays for itself by preventing much more expensive repairs down the road.

What happens if it rains after you apply the sealcoat?

Rain on fresh sealcoat can ruin the job completely, which is why we monitor weather forecasts carefully before starting any project. If unexpected rain hits before the sealcoat cures, we’ll need to start over in affected areas. That’s our responsibility, not yours. We only start jobs when we’re confident in the weather window, and we carry insurance to cover any weather-related issues that might arise.
