Charleston Mold Removal Co. handles the full chain Lowcountry humidity produces: crawl space remediation and encapsulation ($2,000–$12,000), remediation ($500–$6,000), inspection (free to $900), AC and duct cleanup (from $600), and water damage drying (from $1,000).
Crawl Space Mold Removal
Remediation, vapor barrier, and encapsulation — fixing the mechanism instead of scrubbing the symptom.
Mold Remediation
Containment, HEPA filtration, and physical removal, scoped carefully around historic assemblies.
Mold Inspection & Testing
Readings from under the house and inside it — and an honest answer on whether testing changes anything.
AC & Duct Mold Cleanup
Air handlers, coils, and the ductwork running through humid crawl spaces.
Water Damage Restoration
Extraction and metered structural drying, including tidal and storm intrusion.
Cost Guide: What Mold Work Runs in Charleston
Every job class priced for this market, what moves an estimate, and the question that saves the most money.
Why the services come as a set
In this market the moisture usually enters below the floor and shows up everywhere else. The same humid air condensing on floor joists sweats on the ductwork running through the crawl, migrates up into the living space, keeps indoor humidity high enough for growth on a closet wall, and cups the hardwood above it. Companies organized around one product sell that product. We're organized around where the water actually comes from, which is why an inspection reads the whole chain.
Which service fixes which problem
| What you have | What's driving it | The work | Typical range | Time |
|---|---|---|---|---|
| Musty smell near the floor, cupping hardwood, growth on joists | Humid air condensing in a vented crawl space | Crawl remediation and encapsulation | $2,000–$12,000 | 2–4 days |
| Visible growth on walls, ceilings, or trim | Indoor humidity or a specific water source | Containment and HEPA removal | $500–$6,000 | 1–3 days |
| Odor with nothing visible | Growth in a cavity, under flooring, or below the house | Inspection and testing | Free–$900 | About an hour |
| Musty air from vents, condensation on ducts | Cold ductwork running through humid crawl space | AC and duct cleanup | $600–$3,500 | 1 day |
| Tidal or storm intrusion, plumbing failure | Bulk water on a 24-to-48-hour clock | Extraction and metered drying | $1,000–$8,000 | 3–5 days |
Most Lowcountry homes need the crawl space handled plus one other line — and once the crawl is right, the other line frequently gets smaller.
Sequence is the service
The order that works here: address bulk water first, remediate second, seal and dehumidify third, and repair finishes last. Encapsulating over standing water, or refinishing cupped floors before the crawl space is controlled, means paying twice. Our scopes are written in that order with fixed prices per line, separated so you can see which half you're buying and stage them if the budget calls for it.
Service questions
Which service do I actually need?
The inspection answers it, and it starts under the house. A musty smell near the floor or cupping hardwood points to the crawl space. Visible growth on a wall points to remediation. Odor with nothing visible anywhere means meters first. Standing water means extraction, immediately. The inspection is free precisely so the diagnosis doesn't depend on what we'd like to sell.
Do you charge for inspections?
No. Crawl space entry, moisture content readings on joists and subfloor, humidity under and inside the house, vapor barrier and duct condition, photographs, and a written scope with fixed prices are free across all ten communities we serve — including the visits that end with 'a vapor barrier will do it.'
Can one company handle the crawl space and the house?
That's the point of the stack, and here it's the difference between fixing the problem and treating a symptom. In this market the growth you found upstairs is frequently being fed from below, so remediating the room while leaving a vented crawl running means paying twice for the same problem.
