Resurfacing adds a new wearing surface over pavement that remains suitable for use. Replacement removes failed material and rebuilds the necessary layers. The lower-cost option is not always a good option when the original structure has deteriorated.
When the existing driveway can take a resurfacing overlay
Look at the pattern of failures. Stable cosmetic wear and limited superficial scaling can favor resurfacing; deep displacement, drainage problems and widespread cracks shift the decision toward replacement.
A bonded overlay depends on the old pavement being a suitable substrate. If existing concrete flakes or sheds material, surface preparation can be extensive. If slabs have moved, the overlay can crack along the same movement. Check whether the material beneath the decorative finish is intact before pricing any coating. In asphalt, an overlay may preserve the existing base only when load-bearing layers are stable enough to support it, and resurfacing may require localized full-depth patches first. A proposal should show those preparatory repairs rather than advertise resurfacing as a single uniform coating applied over any underlying problem.
What replacement corrects that an overlay cannot
Replacement changes the whole pavement section and creates a separate opportunity to fix grade, subgrade and drainage. That can be expensive and disruptive, but resurfacing cannot provide those corrections merely by adding thickness. Compare structural suitability, access closure and surface life before selecting the proposal.
Overlay height at the garage and sidewalk
Added overlay thickness can raise garage thresholds and create new drainage lips. The finished grade matters just as much as the overlay product or surface color, and a cheap overlay that makes water collect at the building is not a saving.
One overlooked factor is whether the existing surface is already near the maximum height at a garage or sidewalk. Adding even a modest overlay can change how a tire rolls across the threshold or where rainwater gathers. An owner should ask for the intended elevation and how joints remain functional.

Common questions about driveway resurfacing vs replacement
Can I resurface a concrete driveway that has sunken slabs?
Not as a fix for the sinking. An overlay follows the slab beneath it, so if a panel has dropped or is still moving, the new surface will crack or step along the same line. The sunken slab has to be lifted, supported or replaced first, and only then is resurfacing worth considering for appearance.
Ask whether a quote for resurfacing includes that support work or assumes the slabs are stable.
Does flaking concrete have to be removed before a driveway is resurfaced?
Yes. A resurfacing layer can only bond to clean, sound concrete, so loose flakes, scaling paste and weak surface material have to come off first. If the coating goes over loose material, it can lift away with it. How much preparation is needed depends on how deep the damage goes.
When flaking is widespread and deep, preparation can grow to the point where replacement deserves a price comparison.
Do potholes have to be repaired before an asphalt driveway is overlaid?
They should be. Potholes and areas of broken asphalt usually sit over weak or wet base, and a new overlay laid on top will crack and settle in the same places. Those areas are normally cut out and patched full depth before the overlay goes down, so the new surface has stable support throughout.
A quote that lists the overlay without any patching should explain why none is needed.
