Asphalt Seal Coating & Crack Filling in San Antonio, TX
San Antonio pavement takes a beating from the top and the bottom. Long stretches of 100°F-plus summer heat and intense UV oxidize asphalt until the surface turns grey, brittle, and porous, while the city's place in 'Flash Flood Alley' means a single spring thunderstorm can push a lot of water into every open crack. Census ACS 5-year (2022) data puts the median San Antonio home at a 1983 build date, so a great many driveways here have already lived through four decades of that cycle — and with 51.9% of homes owner-occupied, most of those driveways are a homeowner's problem to solve, not a landlord's.

Why driveway sealcoating is different in San Antonio
The bigger local factor is underfoot. Expansive clay soils across much of the region swell and shrink as the area swings between drought and heavy rain, and the same movement that racks door frames and throws driveway gates out of plumb also opens cracks across asphalt. Once those cracks stay open through a Flash Flood Alley downpour, water reaches the base, softens it, and the pavement starts to fail from below — which is why crack filling and patching come first and seal coat goes on afterward, not the other way around.
Problems we fix in San Antonio
- Grey, chalky, oxidized surface
Sustained San Antonio heat and UV burn off the binder at the surface, leaving asphalt pale, brittle, and porous. That porous surface soaks up the next storm instead of shedding it.
- Cracks that reopen with the soil
Expansive clay under much of the region moves seasonally between drought and heavy rain, so cracks in a driveway can widen after a dry summer. Rubberized filler is made to flex with that movement rather than crack straight back open.
- Water destroying the base
In Flash Flood Alley, spring and early-fall thunderstorms drop a lot of water fast. Anything that reaches the base through an unsealed crack undermines the pavement and turns a hairline into a pothole.
- Oil and fuel spots
With attached two-car garages the norm across San Antonio's post-WWII ranch tracts and newer subdivisions, drip stains collect in the same spots for years. Oil and fuel soften the binder, and seal coat will not bond over an untreated spot without priming.
- Sealing over pavement that is already broken
Seal coat is a protective film, not a structural repair. Spreading it over alligatored or crumbling asphalt hides the damage for a season and wastes the work.
- Sealing new asphalt too early
Newer construction on the north, northwest, and far west sides often means fresh driveways and private drives. New asphalt needs time to cure before it is sealed, or the coating will not hold.
- Tracking and tire marks
On a 100°F-plus San Antonio afternoon, returning vehicles to a coating too soon leaves scuffs and power-steering marks. We tell you the cure window before we start so you can plan parking.
What we do
Cracks are cleaned out of dirt, oak and cedar debris, and vegetation, then filled with a flexible rubberized material that can move with San Antonio's clay soils.
Contaminated areas — usually right where a two-car garage apron meets the drive — are cleaned and primed so the seal coat actually bonds instead of peeling.
Failed areas and crumbling edges are patched first. Edges take the worst of it where drainage runs hard during Flash Flood Alley storms.
Seal coat is applied by squeegee, spray, or both depending on surface condition and size, restoring a uniform surface that resists UV oxidation.
We handle larger surfaces too, including shared drives and lots in HOA-governed subdivisions and gated communities on the North Side and far West Side.
Stalls, arrows, fire lanes, and accessibility markings can be restriped after sealing so the lot reads clearly again.
Licensing, permits and codes in Texas
Texas has no statewide general contractor or home improvement contractor license. The Texas Department of Licensing and Regulation (TDLR) is the primary state agency for most licensed construction trades, including electricians and air conditioning/refrigeration contractors, while plumbing and gas piping are licensed separately by the Texas State Board of Plumbing Examiners. Pavement sealing and striping are not among those trades, but requirements can change and local rules apply — verify any current requirement with TDLR and with the City of San Antonio before work begins. If you are in an HOA-governed subdivision or gated community, which is the norm in newer North Side and far West Side developments, check your association's rules on driveway work and contractor access first.
Timing and availability
Seal coating goes on best during warm, dry stretches, which San Antonio has plenty of — but scheduling around weather matters. Spring storms from March through June bring hail, straight-line winds, and heavy rain, and the first cold snap in December or January can bring a hard freeze like the statewide February 2021 event, so late-season work needs a clear window. Call (888) 996-7488 any time; our phones are answered 24/7, we can usually get a technician out same-day or next-day in most areas, and the estimate is free before anything starts.

Seal Coating questions in San Antonio
When is the best time to seal coat a driveway in San Antonio?
Warm, dry weather is what the material needs, so the long San Antonio warm season gives you a wide window. The main thing to avoid is applying just ahead of a spring or early-fall thunderstorm, since this is Flash Flood Alley and rain on fresh seal coat can ruin the job. A technician will check the forecast with you before scheduling.
My driveway cracked after a dry summer — will seal coating fix it?
Seal coat alone will not. Expansive clay soils in the San Antonio region shift between drought and heavy rain, and those movement cracks need to be cleaned and filled with a flexible rubberized material first. Seal coat then goes over the repair to protect the surface from UV and water.
I have a new driveway in a newer North Side subdivision. Can it be sealed right away?
No — sealing too early is one of the surest ways to waste the work. New asphalt has to cure before it takes a coating, and much of the construction on the north, northwest, and far west sides is recent enough that this comes up often. We will look at the pavement and tell you straight whether it is ready.
How long do I need to stay off the pavement?
It depends on the product, the surface, and the weather that day. On a 100°F-plus San Antonio afternoon, heat affects cure behavior and returning traffic too soon leaves tire and power-steering marks. Your technician gives you the cure window before starting so you can plan parking.
Do you handle parking lots and private roads, not just driveways?
Yes. We cover crack filling, patching, seal coating, and line striping on parking lots and private roads, including shared drives in HOA-governed subdivisions and gated communities. The estimate is free either way.
