What Proper Seal Coating Does

Your driveway stops looking worn and faded. The rich black finish comes back, and more importantly, you’re protected against the stuff that destroys asphalt around here.

Water can’t penetrate and freeze. Oil stains wipe off instead of soaking in permanently. Road salt from winter doesn’t eat away at the surface.

You get 3-5 more years before needing major repairs. That’s thousands saved compared to letting your driveway deteriorate and having to resurface or replace it. The investment pays for itself by preventing bigger problems down the road.

We Know Long Island Driveways

We’ve been handling asphalt work in Central Islip and surrounding areas for years. We understand what Long Island weather does to driveways and parking lots.

The coastal air, freeze-thaw cycles, and road salt create specific challenges that require the right materials and timing. We don’t rush jobs or cut corners because we know what works here and what doesn’t.

You’re working with contractors who live in this area and have seen every type of asphalt problem Long Island throws at properties.

Asphalt Sealing Process

How We Handle Your Project

First, we clean your driveway thoroughly. Oil stains get treated, debris removed, and any vegetation growing through cracks gets cleared out. This prep work determines how well the sealer bonds.

Next comes crack filling if needed. Small cracks get sealed so water can’t get underneath and cause bigger problems. We let everything cure properly before moving to the next step.

Then we apply the sealer using professional equipment that ensures even coverage. We typically apply two thin coats rather than one thick coat because it dries better and lasts longer. Weather conditions have to be right – no rain in the forecast and temperatures above 50 degrees.

You can walk on it after 4-6 hours, but we recommend waiting 24-48 hours before driving on it. The curing process continues for several days, so following our timeline protects your investment.

Blacktop Sealing Central Islip

What's Included In Our Service

Complete surface preparation including power washing, oil stain treatment, and debris removal. We handle minor crack filling as part of the process because leaving cracks unsealed defeats the purpose.

Professional-grade sealer application with commercial equipment. We use coal tar or asphalt emulsion sealers depending on your specific situation and traffic patterns. Residential driveways and commercial parking lots have different requirements.

We work around Central Islip’s weather patterns and know when conditions are right for application. Rushing the job because of weather leads to peeling and early failure. We’d rather reschedule than give you poor results that won’t last.

How often should I seal coat my driveway in Central Islip?

Every 2-3 years for most residential driveways, but it depends on traffic and exposure. Driveways that get heavy use or face south with more sun exposure may need sealing every 2 years. If your driveway still looks black and water beads on the surface, you can wait. Once water soaks in instead of beading up, it’s time to reseal. Long Island’s freeze-thaw cycles and road salt make regular sealing more important than in other climates.

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

Late spring through early fall when temperatures stay above 50 degrees for at least 48 hours after application. We avoid the hottest summer days because sealer can dry too quickly and not bond properly. Fall is often ideal because temperatures are moderate and there’s less chance of sudden weather changes. We monitor weather forecasts carefully and won’t start a job if rain is expected within 24 hours of application.

How long does seal coating take to dry completely?

You can walk on it after 4-6 hours, but wait 24-48 hours before driving on it. The sealer continues curing for several days, reaching full hardness after about a week. Hot, dry weather speeds up drying while cool, humid conditions slow it down. We’ll give you specific timing based on weather conditions when we do your job. Following our drying recommendations prevents tire marks and premature wear that can ruin the finish.

Will seal coating fill cracks in my driveway?

Small hairline cracks get filled during the sealing process, but larger cracks need separate crack filling first. Seal coating isn’t thick enough to fill significant cracks, and trying to use it that way leads to premature failure. We handle minor crack repair as part of our service, but major cracking might indicate underlying problems that need addressing before sealing. Proper crack filling before sealing prevents water penetration and extends the life of both repairs.

How do I maintain my driveway after seal coating?

Keep it clean and address oil spills quickly. Fresh seal coating resists oil stains better, but leaving spills sitting will eventually cause problems. Avoid using sharp objects or metal snow shovels that can scratch the surface. Don’t park in the exact same spots every day if possible – varying tire placement prevents premature wear patterns. Power washing occasionally helps remove dirt and debris, but avoid harsh chemicals that can break down the sealer.

What's the difference between different types of sealers?

Coal tar sealers offer better protection against gas and oil but take longer to dry. Asphalt emulsion sealers dry faster and work better in cooler weather but don’t resist chemicals as well. For most Central Islip residential driveways, either works fine when applied properly. Commercial parking lots with heavy traffic or gas stations need coal tar’s extra durability. We recommend the right sealer based on your specific situation, traffic patterns, and exposure to automotive fluids.
