On a Longs job, crawl Space Mold Remediation follows from the inspection rather than preceding it — there is no point specifying this work before the source of the water is known.
There is growth on the joists or subfloor, and a smell coming up into the house.
Mold remediation on lowcountry and coastal plain ground
Humidity near Longs stays high enough for long enough that growth here is sustained rather than seasonal. Remediation without humidity control does not hold on the coastal plain — the space simply returns to the conditions that produced it.
Flood-zone construction around Longs is built elevated, which means newer homes have crawl spaces too. Newer framing, the same conditions underneath.

Why it is worth dealing with now
A crawl space problem in Longs is not self-limiting. The conditions that created it are still there, and they are still working.

Mold remediation in Longs: common questions
Will it come back after remediation in my Longs home?
Not if the moisture is corrected, and very likely if it is not. Around Longs the conditions that produced it are seasonal and recurring, so the humidity control is the durable half of the job.
Can growth under the floor affect the air upstairs?
It can. Air moves upward through a house and draws crawl space air into the rooms above through gaps around pipes and ducts, which is why a Longs homeowner usually notices the smell in a hallway before they see anything.
My house is near the River Swamp. Does that change anything?
It can. Being close to the 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.
Will my Longs crawl space dry out if I open the vents?
Usually not. For much of the year the air around Longs is warmer and wetter than the crawl space, so opening it up deposits moisture on the cool joists instead of carrying it away.
How quickly does water under a Longs 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 Horry County that window is shorter in summer than in winter, because the space stays warm and humid.
Can I just spray bleach on it?
Spraying a surface biocide on damp timber treats the visible growth and leaves both the moisture and the material it is feeding on in place. It also adds water. Growth on porous material generally needs the material removed or properly cleaned, and the moisture source corrected, or it comes back.
