What Proper Seal Coating Actually Does

You get a protective barrier that keeps water, salt, and UV rays from breaking down your asphalt. That means fewer cracks, no potholes, and a surface that looks fresh for years instead of fading within months.

Your driveway becomes the kind that neighbors notice in a good way. The deep black finish makes your property look maintained and cared for, which matters whether you’re living there or trying to sell.

Most importantly, you avoid the headache of emergency repairs. When water can’t penetrate the surface, it can’t freeze and expand during Long Island winters. When UV rays can’t oxidize the asphalt, your driveway doesn’t turn gray and brittle.

We’ve been protecting driveways and parking lots throughout Lake Ronkonkoma and surrounding areas for years. We understand how harsh winters and hot summers affect asphalt surfaces here.

You’re not getting a crew that learned the trade somewhere else and moved here. We’ve seen what works in this climate and what doesn’t. We know when to apply sealcoating for the best cure, and we use materials that handle the temperature swings Long Island throws at us.

Our reputation comes from property owners who call us back every few years because they know we do it right the first time.

Asphalt Sealing Process

How We Seal Your Driveway Right

We start by cleaning your asphalt surface completely. Oil stains, dirt, and debris have to come off first, or the sealcoating won’t bond properly. We use professional cleaning equipment, not just a garden hose.

Next, we fill any cracks that could let water through. Small cracks get sealed with hot pour crack filler that flexes with temperature changes. This step is crucial because sealing over cracks without filling them first just hides the problem temporarily.

Then we apply the sealcoating using professional-grade squeegees or spray equipment, depending on your surface. We work in sections to ensure even coverage and the right thickness. Too thin and it won’t protect. Too thick and it won’t cure properly.

The final step is letting it cure completely before you drive on it. We’ll tell you exactly when it’s safe to use your driveway again, usually 24-48 hours depending on weather conditions.

What's Included In Professional Seal Coating

You get thorough surface preparation, which most contractors skip. We remove oil stains, clean the entire surface, and fill cracks before applying any sealcoating. This preparation work is what makes the difference between a seal coat that lasts two years versus one that starts failing after the first winter.

We use commercial-grade sealcoating materials designed for New York weather conditions. The sealer we apply contains sand for traction and UV inhibitors to prevent premature fading. It’s not the same product you’d buy at a home improvement store.

Your edges get hand-detailed to ensure clean lines against concrete, grass, or other surfaces. We protect your landscaping, walkways, and garage doors from overspray. When we’re finished, you’ll have a uniformly sealed surface with professional-looking results that enhance your property’s appearance.

Most driveways in Lake Ronkonkoma need seal coating every 2-3 years, depending on traffic and weather exposure. If your driveway gets full sun all day, you might need it every 2 years because UV rays break down the asphalt faster. Driveways in shaded areas or with light traffic can often go 3 years between applications. The key indicator is color – when your asphalt starts looking gray instead of black, it’s time to seal coat again. Don’t wait until you see cracks forming, because by then water damage may have already started.
Late spring through early fall is ideal for seal coating in our area. We need temperatures above 50 degrees and no rain in the forecast for at least 24 hours after application. The sweet spot is usually May through September when we have consistent warm, dry weather. Avoid seal coating in late fall because the sealer needs time to cure properly before winter freeze-thaw cycles begin. Summer applications work well too, but we schedule them for cooler parts of the day to prevent the sealer from drying too quickly in extreme heat.
Plan to keep vehicles off your driveway for 24-48 hours after seal coating, depending on weather conditions. In hot, dry weather, you might be able to drive on it after 24 hours. In cooler or humid conditions, wait the full 48 hours. You can walk on it after about 4-6 hours, but avoid dragging anything across the surface. The sealer may look dry on top but still be soft underneath. Driving on it too early will leave tire marks and damage the finish, potentially requiring reapplication of those areas.
Small cracks need to be filled before seal coating, and we include crack filling in our service. Cracks wider than a quarter-inch should be cleaned out and filled with hot pour crack filler that bonds to the asphalt and flexes with temperature changes. Simply seal coating over cracks without filling them first means the cracks will telegraph through the sealer within months. For driveways with extensive cracking or structural issues, seal coating alone won’t solve the problem – you might need repairs or replacement. We’ll assess your driveway’s condition and recommend the best approach.
Professional-grade sealcoating contains sand additives that provide traction, so your driveway shouldn’t be more slippery than before. In fact, a properly sealed surface often provides better traction than worn, oxidized asphalt. The key is using the right type of sealer and applying it at the correct thickness. Cheap sealers without sand additives or sealer applied too thick can create a slippery surface. We use commercial-grade products with appropriate sand content and apply them at manufacturer-recommended thickness to ensure both protection and safety.
Professional seal coating typically costs 2-3 times more than DIY materials, but you’re paying for preparation work, commercial-grade materials, and proper application techniques that make the job last longer. DIY seal coating often fails within a year because homeowners skip surface preparation, use inferior products, or apply the sealer incorrectly. When you factor in the cost of your time, equipment rental, and the likelihood of needing to redo the job sooner, professional application usually provides better value. Plus, if something goes wrong with a professional job, you have recourse – if your DIY job fails, you’re starting over from scratch.
