We will tell you if crawl Space Vapor Barrier Installation is not what your North Myrtle Beach 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 North Myrtle Beach 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.
Low ground and a long wet season change what this work has to withstand around North Myrtle Beach. Homes near the Little River Swamp in particular tend to need the drainage question answered as well, or the space simply returns to how it was.

Vapor barrier in North Myrtle Beach: 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 the Little River Swamp, drainage comes first or the sheeting simply floats on it.
Barrier or full encapsulation for a North Myrtle Beach home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Horry County property needs should follow a humidity reading, not a preference.
My house is near the Little River Swamp. Does that change anything?
It can. Being close to the Little 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 North Myrtle Beach crawl space dry out if I open the vents?
Usually not. For much of the year the air around North Myrtle Beach 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 North Myrtle Beach 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.
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.
