Concrete Repair & Resurfacing
Not every cracked or sunken slab needs to be torn out and repoured. Central Florida's heat cycles, heavy summer rain, and sandy soil all put real stress on aging concrete, and the honest answer to "repair, resurface, or replace" depends on what's actually wrong underneath the surface — not just what it looks like on top.
Figures above are published planning ranges, not a quote for your project — repair and resurfacing costs depend heavily on the extent and cause of the damage. Request a site-specific estimate before assuming a number.
What's actually wrong before you decide what to do about it
Surface problem: repair or resurface
Hairline cracks, surface pitting, and cosmetic wear on a slab that's still structurally flat and stable are typically resurfacing candidates — a new overlay restores the look without a full tear-out.
Base problem: replace
Wide, spreading cracks, sunken sections, or a slab that rocks or tilts point to a failed base underneath — compaction failure, erosion, or soil movement. Resurfacing over that just hides the problem temporarily.
Repair, resurfacing, and replacement questions
How do I know if my driveway needs repair or full replacement?
Hairline surface cracks, minor pitting, and cosmetic discoloration are usually repair or resurfacing candidates. Wide cracks that keep growing, sections that have visibly sunk or tilted, or a slab that's crumbling below the surface generally point to a base failure that resurfacing won't fix — that's a replacement conversation. See our Repair or Replace guide for the full breakdown.
What causes concrete driveways to sink or settle over time?
Most sinking traces back to the base underneath, not the concrete itself — inadequate compaction during the original pour, erosion or washout under the slab from poor drainage, or Central Florida's sandy soil shifting over time. A slab is only as stable as what's underneath it, which is why base preparation matters as much to long-term durability as the pour itself.
Can a cracked concrete slab be resurfaced instead of replaced?
Often, yes — if the cracking is cosmetic and the base underneath is still sound, a resurfacing overlay (commonly around 1 inch) can restore the surface without a full tear-out. If the cracks indicate the base has failed, resurfacing over that problem just delays it, and typically costs more in the long run than fixing the base and repouring.
How much does concrete resurfacing cost compared to a new pour?
A full replacement, including demolition of the old slab, runs a published $8–$12 per sq ft in Florida cost data — resurfacing is generally cheaper per square foot since there's no demolition and less material, but a confirmed side-by-side range isn't available as of this writing. Treat any number here as a planning estimate; see Resurfacing vs. a New Pour for how to think through the trade-off, then request a site-specific estimate.
Is a permit required for a thin concrete resurfacing overlay in Florida?
Often not — a thin overlay (around 1 inch) applied to an existing slab commonly falls outside the permit requirement that applies to pouring a new driveway slab, since it isn't new construction. This varies by jurisdiction, so confirm with the office listed in the South Lake Permit Directory before assuming either way.
Is it worth resurfacing a driveway before selling a rural property?
There's no confirmed data on how resurfacing specifically affects a sale price or appraisal for a rural South Lake County property — this is a real question buyers and sellers ask, but it isn't one we have a sourced answer for. What is true: a visibly cracked, sunken, or patched driveway is a first impression, and resurfacing is generally the lower-cost way to address that impression compared to a full replacement.
