Sealcoating can be worthwhile on structurally sound asphalt when the surface is weathering and a compatible coating can help limit deterioration. It is not worthwhile as a substitute for patching potholes or fixing wet, unstable base.
When sealcoating makes sense on an asphalt driveway
Sealcoating should be evaluated as a surface-maintenance treatment on sound asphalt. Look for whether the pavement is still carrying vehicle loads without widespread rutting or fatigue cracking. The fact that an older driveway has faded does not mean it has lost load-bearing capacity, and a darkening coat can make suitable pavement look more uniform.
A practical test is whether the pavement has a stable shape. A sound asphalt surface with fading color is different from a drive with deep depressions and broken edges.
Why sealcoating cannot stand in for structural repair
Interlocking fatigue cracks, potholes, rutting and soft edges point to other repairs. Treat those as separate work items before deciding what portion of the drive should be sealed. If rainwater flows beneath a patch, the issue is not solved by sealing its visible top. The value of sealcoating comes from maintaining a pavement that still performs rather than concealing structural defects that require another method.
What a sealcoating quote should include
Clean, stable asphalt is a very different preparation job from a driveway with oil stains, vegetation and broken edges. Cost is affected by coverage area, cleaning, crack treatment, coating product, coat count and curing conditions. Ask how the asphalt will be cleaned and dried, what happens around oil contamination, how cracks are treated and whether the coating will be one or more coats. The number of coats and surface repairs should be specified rather than implied, and a quote that omits preparation does not describe the same service as one that includes it.
The surface also needs a realistic traffic restriction while the coating sets under actual weather conditions, suited to the household. The cost should not be turned into a made-up universal price per square foot.

Common questions about is asphalt driveway sealcoating worth it
How often should an asphalt driveway in San Antonio be sealcoated?
There is no fixed calendar that suits every driveway. Reseal when the previous coat has worn through and the asphalt is turning gray and dry again, which happens faster in full sun, on steep sections and where cars turn often. Sealing too often can build up layers that crack and peel, so wear, not habit, should set the schedule.
A contractor can tell you whether the old coat is worn enough to justify a new one.
Should cracks be filled before an asphalt driveway is sealcoated?
Yes, where the cracks are individual and the pavement around them is sound. Sealcoat is a thin surface coating and does not fill or bridge cracks, so they are cleaned and filled with a crack sealant first. Widespread alligator cracking is different: it needs patching and base repair, not crack filling, before any coating.
A quote should say which cracks will be filled and with what, rather than folding that into "prep."
Can a brand-new asphalt driveway be sealcoated right away?
Usually not. Fresh asphalt needs time to cure and harden before a coating goes on, and sealing too early can trap oils and leave the surface soft. The right waiting period depends on the mix and the weather, so ask the paving contractor and the coating manufacturer's guidance rather than going by a general rule.
Until then, the new asphalt does not need a coating to perform.
