Sealcoating is the most cost-effective maintenance decision you can make for asphalt pavement in North Hills. A properly sealed parking lot resists water penetration, UV damage, oil spills, and oxidation — and lasts significantly longer than one left unprotected. PaveMaster has been applying commercial sealcoating across Nassau County since 1979.

What Sealcoating Does — And What It Doesn’t
Sealcoating applies a thin protective layer over existing asphalt, sealing surface pores against water, UV rays, oil, and road salt. It slows oxidation, keeps the pavement flexible longer, and gives the lot a clean, jet-black appearance. What it doesn’t do: fix structural problems. Sealcoating goes over sound asphalt. If your lot has significant cracking or potholes, those get addressed first. Sealcoating is the final step, not the first one.
Crack Sealing Comes First
Sealcoating over open cracks is a mistake. Water will find them, and Long Island’s freeze-thaw cycles will make them worse regardless of what’s on the surface. The correct sequence: crack sealing first, then sealcoating. We fill cracks with hot-pour rubberized sealant that flexes with temperature changes rather than becoming brittle.
Line Striping — Same Visit
Fresh sealcoat is the right moment to restripe. PaveMaster handles parking stalls, fire lanes, directional arrows, and ADA-compliant markings as part of the same mobilization — one crew, one visit, one invoice.
