On a Sunset job, crawl Space Vapor Barrier Installation follows from the inspection rather than preceding it — there is no point specifying this work before the source of the water is known.
Bare soil under the house is evaporating moisture into the space every day.
Vapor barrier on piedmont and upstate ground
On clay the ground under a Sunset house holds water long after rain, so the barrier is doing two jobs — stopping soil moisture coming up, and keeping the space off ground that stays wet for days at a time.
Clay also makes Sunset crawl spaces slow to dry. The surrounding ground gives moisture back reluctantly, which is why this stage is finished against a reading rather than a date.

What the work involves
What is included on a typical Sunset property:
- Clearing and preparation of the crawl space floor
- Reinforced polyethylene barrier across the full soil area
- Overlapped and sealed seams
- Barrier carried up and sealed to walls and piers
Why it is worth dealing with now
Waiting is the expensive option here. Moisture that has been under a Sunset floor for a year has already changed what the repair involves.

Vapor barrier in Sunset: 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 Twelve Mile River Watershed Eight Reservoir, drainage comes first or the sheeting simply floats on it.
Barrier or full encapsulation for a Sunset home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Pickens County property needs should follow a humidity reading, not a preference.
Why does my Sunset crawl space stay wet for days after the rain stops?
Piedmont clay. Around Sunset, at roughly 1024 feet, the ground holds water against the foundation long after the surface looks dry.
How quickly does water under a Sunset 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 Pickens County that window is shorter in summer than in winter, because the space stays warm and humid.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Sunset call, because everything after it depends on the answer. A supply line, a drain, water rising through the soil and runoff coming in through the vents each leave different evidence.
What is the difference between a vapor barrier and encapsulation?
A vapor barrier covers the soil and stops ground moisture evaporating into the space. Encapsulation goes further — ground, walls and usually the vents are sealed and the space is brought inside the building envelope, normally with a dehumidifier to control humidity directly. Encapsulation does more and costs more.
