Quick answer
In Charleston, a typical water damage job costs $1,200–$5,000 for extraction and structural drying; small clean-water losses start under $1,000 and large or contaminated losses run $5,000–$15,000+. Mold remediation is usually a separate quote at $1,500–$6,000, and flooded crawl-space cleanup adds roughly $1,500–$6,000 depending on standing water and contamination.
Ranges below are compiled from national cost guides (HomeWyse, Angi-style datasets) as of September 2026, adjusted for typical Lowcountry scope (crawl spaces, high humidity). Every loss is scoped on site; treat these as orientation, not quotes. We are collecting direct quotes from Charleston companies and update this page as they come in.

| Service | Typical Charleston price | Notes |
|---|---|---|
| Inspection & moisture assessment | Free – $300 | Most restoration companies assess free during emergencies; standalone mold/moisture inspections with testing cost more |
| Water extraction | $500 – $2,000 | Truck-mounted extraction; priced by volume, access, and water category |
| Structural drying & dehumidification | $1,000 – $3,000 | Air movers + dehumidifiers over 3–5 days with daily moisture readings; the core of most jobs |
| Clean water loss (Category 1), total | $1,200 – $5,000 | Supply lines, sink overflows caught early — the typical Charleston job |
| Gray water loss (Category 2) | $3,000 – $8,000 | Appliance discharge, washing machines, dishwashers; adds sanitizing and often material removal |
| Sewage / black water (Category 3) | $5,000 – $15,000+ | Porous materials come out, everything is disinfected; see our sewage cleanup page |
| Mold remediation | $1,500 – $6,000 | National cost-data range; large or HVAC-involved jobs run $8,000+ — see mold cost details |
| Flooded crawl space cleanup | $1,500 – $6,000 | Extraction, debris removal, drying, antimicrobial treatment; vapor barrier/encapsulation is extra |
| Drywall removal & replacement | $1.50 – $3.50 / sq ft | Flood-cut removal plus hang, tape, finish |
| Flooring replacement | Varies widely | Carpet $3–$8/sq ft installed; engineered wood and LVP more; heart-pine restoration in historic homes is specialist work |
Restoration is priced by affected area and water category more than by whole-house square footage — one wet bathroom is the cheap end, a whole first floor after a storm is the expensive end.
| Affected area | Clean water (Cat 1) | Contaminated (Cat 2–3) |
|---|---|---|
| One room / under 100 sq ft | $800 – $2,000 | $2,500 – $5,000 |
| Several rooms / 100–500 sq ft | $2,000 – $5,000 | $5,000 – $10,000 |
| Whole floor / 500+ sq ft | $4,000 – $8,000 | $8,000 – $15,000+ |
Homeowners are often surprised that water damage restoration splits into two scopes. Mitigation — extraction, drying, demolition of unsalvageable material, sanitizing — is the emergency phase, billed to stop the damage. Reconstruction — new drywall, flooring, cabinets, paint — is the rebuilding phase, priced like any remodel. Some Charleston companies (Paul Davis, for example) run both in-house; others dry the house and hand you to a separate contractor for the rebuild.
The practical takeaway: when comparing quotes, compare mitigation against mitigation and rebuild against rebuild. A company that looks expensive on dry-out but includes the rebuild in one coordinated contract can be cheaper overall — and faster — than a cheap dry-out followed by weeks of contractor shopping. Ask each bidder which phases their number covers.
Water damage is one of the few home problems that gets strictly worse by the hour. Drywall wicks water upward, subfloor swells, and — in a city where indoor humidity sits above 60% for much of the year — mold can colonize within 24–48 hours. A $2,000 dry-out on day one is routinely a $6,000 mold-plus-rebuild job by day five.
Crawl spaces make waiting even more expensive here. Standing water under a Charleston house doesn't stay under the house: moisture migrates into floor systems and living space, and a wet crawl space left for a season becomes a mold remediation and vapor-barrier project instead of a pump-out.
A small clean-water spill on a hard floor is reasonable DIY with fans and a wet vac. Once water reaches drywall, insulation, subfloor or a crawl space, consumer equipment can't verify dryness — and "feels dry" is how mold jobs are born. Professional drying costs less than the mold remediation it prevents.
Companies scope demolition differently: one plans to dry drywall in place, another flood-cuts it. One includes the crawl space, another missed it. Ask each bidder for moisture readings and a written demolition scope — the differences usually explain themselves.
During an active water emergency, most assess the loss free — inspection is how they scope the job. Standalone mold inspections with lab testing are a different service and typically cost $300–$600.
Usually yes for sudden, accidental water (burst pipe, appliance failure) minus your deductible. No for flood — rising water from storms, tides or surge requires a separate flood policy. Mitigation you reasonably perform to prevent further damage is typically reimbursable, so don't delay drying while waiting for an adjuster.
