We will tell you if crawl Space Vapor Barrier Installation is not what your Landrum 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 piedmont and upstate ground
On clay the ground under a Landrum 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 Landrum 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.

- Barrier carried up and sealed to walls and piers
Why it is worth dealing with now
The cost of this work does not stay flat. Every season a Landrum crawl space stays wet moves more of the job from drying towards framing repair.

Vapor barrier in Landrum: common questions
There is already plastic under my Landrum house. Is that enough?
Often not. Most of what we find has been laid loose, has torn, or was never sealed at the seams and walls. Unsealed sheeting performs much closer to bare soil than to a finished barrier.
Barrier or full encapsulation for a Landrum home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Spartanburg County property needs should follow a humidity reading, not a preference.
Do you cover all of Landrum?
Yes — Landrum and the surrounding part of Spartanburg County, including the 29356 area. We also work in nearby Campobello, Gramling and Inman.
What should I have ready when I call about my Landrum home?
Your street in Landrum, when you first noticed it, and what you can see or smell — standing water, a waterline on the piers, insulation hanging down, or a floor that has gone soft. Photographs help.
How quickly does water under a Landrum 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 Spartanburg County that window is shorter in summer than in winter, because the space stays warm and humid.
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.
