Taken on its own, crawl Space Structural Drying treats one part of the problem. Taken in order, it is the part that makes the rest hold. That is how we schedule it on Andrews jobs.
The water is gone but the wood is still wet, and wet wood is what fails.
Structural drying on lowcountry and coastal plain ground
Drying a Andrews crawl space means fighting the outside air for much of the year. Coastal humidity is high enough that ventilation adds moisture rather than removing it, so this is a closed, dehumidified process with the vents shut, not an airing-out.
Low ground and a long wet season change what this work has to withstand around Andrews. Homes near the Black River Swamp in particular tend to need the drainage question answered as well, or the space simply returns to how it was.

Signs you need this
- Water has been removed but the space still smells damp
- Moisture meter readings above roughly 16 percent in joists or subfloor
- Condensation returning on ducts or pipes after the space was cleared
- Dark staining or surface growth on joists and the subfloor underside
What the work involves
What we do on a Andrews job of this kind:
- Moisture mapping with marked, repeatable reading points
- A drying plan with stated target moisture content
- Air movers and dehumidification sized to the crawl space
- Monitoring through the job with readings recorded
Why it is worth dealing with now
Waiting is the expensive option here. Moisture that has been under a Andrews floor for a year has already changed what the repair involves.

Structural drying in Andrews: common questions
Can I just leave fans running under the house?
Moving air around a closed damp space without removing water vapor relocates moisture rather than removing it. In Georgetown County, where the outside air is wet for much of the year, that often makes the space damper.
How do you know when a Andrews crawl space is actually dry?
By reading it. We mark points on the joists and subfloor and re-read the same points through the job, finishing when they hold at target rather than after a set number of days.
How quickly does water under a Andrews house need to come out?
Quickly. Wood starts absorbing moisture immediately and mold can establish on damp material within roughly 24 to 48 hours. In Georgetown County that window is shorter in summer than in winter, because the space stays warm and humid.
Will my Andrews crawl space dry out if I open the vents?
Usually not. For much of the year the air around Andrews is warmer and wetter than the crawl space, so opening it up deposits moisture on the cool joists instead of carrying it away.
My house is near the Black River Swamp. Does that change anything?
It can. Being close to the Black River Swamp usually means a higher water table and a longer wet season under the floor, so drainage and a properly sealed barrier matter more here than they would further from it.
What moisture reading should I be looking for?
Framing lumber is generally considered as dry in service in the region of 12 to 15 percent moisture content, with sustained readings above the high teens being the range where decay becomes a real risk. The right target depends on your climate and construction, which is why we set it per job and write it down.
