Charleston's sandy coastal soil drains fast on the surface but erodes easily underneath — which is why concrete here cracks and sinks more than it would inland. The right fix depends on your soil, how far water needs to travel, and how hard the problem area is to access, which is why this is priced by the item rather than a flat rate.
Why this isn't a race-to-the-bottom quote
A lot of quotes get cheap by cutting corners somewhere you can't see — thin base prep, rushed cure time, or a crew paid too little to care about the finish. We don't price that way. Every range on this page reflects what it actually costs to do this work right in Charleston's heat, humidity, and storm cycles: real material, real skilled labor, no shortcuts. That's also why the number you're quoted holds up instead of growing once the work has already started.
Pricing questions
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.
How much does a stamped concrete driveway cost?
Stamped and decorative overlays typically run $6–$20 per square foot nationally depending on pattern complexity and color work, with driveway-specific stamped overlays commonly landing around $8–$12 per square foot — a mid-size driveway (roughly 500 sq ft) often lands in the $4,000–$6,000 range. General industry context, not a quote for your specific job.
How much does patio resurfacing cost?
Patio overlays follow similar per-square-foot pricing to driveway resurfacing — roughly $3–$7 per square foot for a standard overlay, more for stamped or decorative finishes. Your exact price depends on size and condition, confirmed after a real assessment.
Why does a professional garage floor coating cost so much more than a DIY kit?
Almost all of the difference is prep and material solids. A big-box kit is an acid-etch prep and a thin single coat. A professional system starts with diamond grinding the slab to open the concrete so the coating mechanically bonds, repairs cracks and pitting, tests and mitigates for moisture, and then builds multiple coats of higher-solids commercial resin. The kit is cheaper because it skips the steps that make a coating last — which is why acid-etched floors commonly peel under hot tires within a season or two. Professional coatings generally run about $4–$10 per square foot for epoxy systems and $8–$14 for polyaspartic, as general market context rather than a quote.
What does a garage floor coating cost around Charleston?
As general market context rather than a quote: professional epoxy systems commonly run about $4–$10 per square foot nationally and polyaspartic about $8–$14, and the Charleston-area anchors sit inside that band rather than outside it. Thumbtack's 2026 epoxy garage floor cost table puts a fair-condition 400 to 450 square foot two-car garage at roughly $1,200–$1,350, and the same table puts a damaged slab at roughly $1,300–$1,463 because the repair work is what moves it. A Charleston-specific cost guide published by handoff.ai lands at $3.64–$8.24 per square foot with a typical two-car total near $2,700. Read those as the range an honestly priced job lands in. What your slab costs depends on its condition once it is ground, what the moisture test says, and whether drainage has to be handled first — which is why the number in a proposal comes after an assessment and never over the phone.
How much does drainage or erosion repair cost?
There's no single per-square-foot number here the way there is for resurfacing, because what it takes depends entirely on the underlying problem. But typical items run roughly: a French drain, $15–35 per linear foot (more for a deep or full-perimeter system); yard grading, $1,000–3,300 for a typical yard; permeable pavers, $10–30 per square foot; a downspout extension, $150–350 each.
