We will tell you if crawl Space Vapor Barrier Installation is not what your Quinby crawl space actually needs. Doing this stage out of order is the most common reason the work has to be repeated.
Bare soil under the house is evaporating moisture into the space every day.
Vapor barrier on lowcountry and coastal plain ground
A barrier earns its keep faster around Quinby than almost anywhere. With the water table close to the surface the soil underneath is damp more or less permanently, so an uncovered crawl space floor is evaporating into the space every day of the year.
Coastal Florence County humidity is the other half of it. For much of the year the outside air here is wetter than the crawl space, so any approach that relies on ventilation to finish the job works against itself.

Vapor barrier in Quinby: common questions
Will a barrier stop water that is already getting in?
No. A barrier manages soil moisture and vapor, not liquid water under pressure. If water is entering the space near Wachovia Hills Lake, drainage comes first or the sheeting simply floats on it.
Barrier or full encapsulation for a Quinby home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Florence County property needs should follow a humidity reading, not a preference.
Does storm flooding reach crawl spaces around Quinby?
Yes, and often with nothing visibly broken. After a tropical system the usual picture in Florence County is a saturated crawl space where the water came up through the ground rather than out of a pipe.
Why is my Quinby crawl space wet when nothing has leaked?
Near Quinby that is the normal pattern rather than the exception. At around 118 feet on the coastal plain, the water table sits close enough to the surface that soil under the house can be saturated with no pipe broken.
Can I stay in the house while the work is done?
In almost all cases, yes. The work happens under the floor, and access is usually through an exterior hatch. We will tell you up front if anything about your Quinby property changes that.
Should the crawl space vents be closed?
It depends on your climate. In humid regions, open vents often bring in air that is wetter than the crawl space, which deposits moisture on cool surfaces instead of removing it — so sealing vents and controlling humidity mechanically usually performs better. In drier climates venting can work. This should follow readings, not a rule.
