Sealcoating in Baytown, TX

Sealcoating puts a thin protective layer over asphalt so sunlight, water and spilled oil reach the sealer instead of the pavement. In Baytown, where summer highs sit near 90 degrees for months and rain totals run past 60 inches a year, an unsealed driveway turns gray, loses its fine stone, and opens up small cracks that let water into the base. A sealcoat does not fix a failed driveway, but it keeps a sound one sound for longer.

When to seal

New asphalt needs time to cure first; HomeGuide recommends waiting three to six months. After that, cost guides suggest resealing every 2 to 10 years depending on the product and the climate. Strong sun and heavy rain push toward the shorter end. Good signs it is time: the surface has gone from black to gray, the stone is showing, or water no longer beads.

Weather matters

Sealer needs dry pavement and temperatures roughly between 50 and 95 degrees, and it needs a dry window to cure; HomeGuide lists 12 to 72 hours before driving. On the Gulf Coast that usually means a morning start on a clear forecast, not a day with afternoon storms building. We reschedule rather than seal into rain.

How we do it

• Blow off and sweep the surface, and scrub oil spots
• Fill cracks first so the sealer does not just hide them
• Patch small failed spots that would otherwise break up under the seal
• Apply the sealer in even coats and keep traffic off until it cures

Coal tar and asphalt emulsion

The two common sealer types are coal tar emulsion and asphalt-based emulsion. HomeGuide notes coal tar is tough but has been restricted in many areas over health and runoff concerns, and asphalt emulsion is generally considered the more environmentally friendly choice.

Sealing parking lots

On commercial lots, sealcoating is usually paired with crack sealing and restriping, since fresh sealer covers the old lines. We seal in sections so the business stays open, block each section until it cures, and restripe once the surface is ready. HomeAdvisor lists commercial sealcoating at about $0.15 to $0.30 per square foot, which is why many owners treat it as routine maintenance rather than a repair.

Sealcoat or replace?

Sealcoat is maintenance for sound asphalt. If a driveway has wide alligator cracking or soft spots, sealing it only hides problems for a season. We tell you honestly whether sealing makes sense.
