How can I tell if my driveway has settled or lost its base? (a 2-minute test)
You can get most of the way to an answer yourself, with no tools, on a dry day. First, the tap test: walk the slab and tap firmly with a hammer handle or the heel of your shoe, listening for the change from a solid ring to a hollow, drummy note. Hollow means a void — base material has washed out from under that section and the slab is partly unsupported there. Second, the rock test: stand with one foot on each side of a crack or joint and shift your weight. Any movement or rocking means the two sides are no longer resting on the same base. Third, the puddle check: after the next rain, note where water stands on the slab and where it runs off the edge, because a dip that holds water is both a symptom of settlement and the mechanism that keeps it going. Hollow spots, rocking sections, or standing water mean the conversation starts with the base and the drainage, not the surface — an overlay over any of those inherits the problem. A crisp ring everywhere, no rocking, and water leaving the slab means you are most likely looking at a surface-condition job, which is the cheaper answer.
What's the best time of year to resurface concrete in Charleston?
Fall, for most projects. Overlays and coatings want surface temperatures roughly in the 50-80F range and a dry window of about 24 hours after placement, and Charleston's October and November stretch hits that more reliably than any other part of the year — summer afternoons flash-cure material too fast and pop-up storms interrupt placement, while midwinter cold snaps slow cure and push schedules. Spring works too, with more weather risk. None of this makes other months impossible; it means the crew plans around the forecast instead of the calendar, and the fall window is simply the one where fewer jobs get rescheduled. If you are thinking about it for next season, an assessment now is worth more than a quote in March, because drainage problems are easiest to see while the ground is still wet.
Do I need HOA approval to resurface my driveway?
In many Charleston-area neighborhoods, yes — if your community has an HOA or architectural review board, exterior changes to a driveway or walkway usually need approval before work starts, and decorative finishes like stamped or stained overlays almost always do. A plain repair or a like-for-like resurfacing is sometimes treated as maintenance rather than a change, but that varies by community and the covenants are the authority, not the general rule. The practical step is to check your covenants or ask your HOA manager what an architectural request needs, then submit before scheduling. We can provide the written specification, product and finish details, and proof of insurance that review boards typically ask for.
What should I do about my driveway after flooding or a hurricane?
Wait until the ground dries, then look for what the water moved rather than what it left on the surface. Silt and staining are cosmetic. The things that matter are new dips or rocking sections, joints that have opened up, soil washed out along the slab edges, and any void you can hear as a hollow sound when the slab is tapped — those mean base material left from underneath and the slab is now partly unsupported. Also check where the water actually ran, since a storm usually reveals a drainage path that will do the same damage again. Address the erosion and drainage first; resurfacing over a slab that lost its base just buys a nicer-looking version of the same problem.
How much does driveway resurfacing cost in Charleston?
A standard driveway overlay typically runs $3–$7 per square foot nationally, with more involved crack repair, grinding, or leveling pushing toward the higher end. That's general context, not a quote — your actual price depends on your driveway's size and condition, confirmed after a real assessment.
Can you resurface a cracked driveway without a full replacement?
In most cases, yes. If the slab underneath is structurally sound, we apply a bonded overlay directly over the existing concrete instead of a full tear-out and repour — faster, less disruptive, and less expensive than replacement.
Why does my driveway keep cracking even after it's been patched?
Cracking is usually a symptom of what's happening underneath the slab, not a flaw in the surface. Charleston's heavy rain and coastal soil let water erode the base under the concrete, and a patch on top doesn't fix that — the crack (or a new one nearby) comes back until the drainage issue underneath is addressed.
How long does driveway resurfacing take?
A standard residential driveway overlay is typically a matter of days once scheduled, not weeks — actual duration depends on size, weather, and cure time.
