What Proper Seal Coating Does

Your asphalt faces a beating every day. Rain seeps into cracks, freezing and expanding during Long Island winters. UV rays bake the surface until it becomes brittle and starts cracking. Oil drips from cars create permanent stains that eat away at the asphalt.

Quality seal coating creates a protective barrier that blocks water penetration and UV damage. You get 3-5 additional years from your existing asphalt instead of facing a complete replacement. The rich black finish restores that new driveway look while making your property more attractive.

Most importantly, you avoid the stress of watching your driveway deteriorate and the shock of replacement quotes that can run $8,000-$15,000 for a typical residential driveway. Seal coating costs a fraction of that while delivering real protection.

Asphalt Sealing Process

How We Apply Seal Coating Right

Our process starts with thorough surface cleaning using commercial blowers and brushes to remove dirt, debris, and loose materials. Any cracks larger than hairline width get filled with crack filler and allowed to cure properly before seal coating application.

Next comes the actual sealer application using professional-grade equipment that ensures even coverage and proper thickness. We apply the sealer in overlapping passes to avoid thin spots or missed areas that can lead to premature failure.

Weather conditions matter significantly for seal coating success. We only apply when temperatures will stay above 50 degrees for 48 hours and no rain is forecast during the curing period. This timing ensures the sealer bonds properly and cures to full strength before exposure to traffic or weather.

What's Included in Our Service

Every seal coating job includes complete surface preparation, crack filling for cracks up to 1/4 inch wide, and two coats of commercial-grade sealer when conditions require it. We use coal tar or asphalt-based sealers depending on your specific surface and traffic conditions.

You also get clear instructions for curing time and when it’s safe to drive on the sealed surface. Most residential driveways need 24-48 hours before light foot traffic and 72 hours before vehicles, depending on weather conditions during application.

Our service covers both residential driveways and commercial parking lots, with scheduling that works around your business operations when needed. All work comes with cleanup of any sealer that gets on sidewalks, garage floors, or other unintended surfaces during application.

Most driveways in the Ronkonkoma area need seal coating every 2-3 years, depending on traffic and weather exposure. If your driveway gets heavy use or faces south with full sun exposure, you might need sealing closer to every 2 years. Driveways with lighter traffic and some shade protection can often go 3 years between applications. The key is applying seal coating before you see significant cracking or water penetration, not waiting until damage is obvious.
Late spring through early fall works best for seal coating, typically May through September. You need temperatures above 50 degrees for at least 48 hours after application, with no rain during the curing period. Summer applications cure faster but require scheduling during cooler parts of the day to avoid application problems. Fall applications work well because temperatures are moderate and there’s typically less rain than spring, giving the sealer optimal curing conditions.
Seal coating typically takes 24-48 hours for foot traffic and 72 hours before you can drive on it safely. Hot, dry weather speeds up curing while cool or humid conditions slow it down. The surface might look dry after 12 hours but hasn’t reached full strength yet. Driving on seal coating too early can leave tire marks or damage the protective layer, so it’s worth waiting the full recommended time even if it looks ready.
Seal coating fills hairline cracks and minor surface imperfections, but larger cracks need separate crack filling before sealer application. Cracks wider than about 1/8 inch should be filled with crack filler and allowed to cure before seal coating. This prevents the sealer from flowing into the crack and leaving thin spots on the surface. Proper crack repair before sealing gives you better protection and longer-lasting results.
Professional seal coating typically costs $0.15-$0.35 per square foot, while DIY materials run about $0.08-$0.12 per square foot. However, professional application includes surface preparation, proper equipment, commercial-grade sealers, and experience avoiding common mistakes that can cause premature failure. DIY seal coating often needs reapplication sooner because of application errors, thin coverage, or inadequate surface prep, making professional application more cost-effective long-term.
Fresh oil stains need treatment before seal coating because sealer won’t adhere properly over petroleum products. Old, weathered oil stains that have been cleaned and aren’t actively leaching oil can usually be sealed over, though they might show through slightly. The best approach is cleaning oil stains with degreaser, allowing complete drying, then applying a primer designed for oil-stained asphalt before seal coating. This ensures proper adhesion and long-lasting protection.
