Lowcountry Foundation Repair Case Studies: Wood Rot and High Humidity Under Mt. Pleasant Home is Fixed!

Tuesday, November 6th, 2018 by Michael Connolly


Deidra B. of Mount Pleasant, SC had a moisture problem in her home that caused a section of her subfloor to rot, and grow mold. The high humidity under the home needed to be fixed. Deidra called Lowcountry Basement Systems for help.



The first step in fixing the humidity and wood rot issue was to replace two sections of the subfloor with new wood. Two sheets were needed for the install, during which five old, nasty wooden joists were replaced with new fresh wood.

Lowcountry Basement Systems then installed a Complete Clean Space Encapsulation System in Deidra’s crawl space. To reduce moisture and remove humidity from the crawl space, Lowcountry Basement Systems first removed the debris and failing subfloor insulation under the home to perform the work. After the debris was removed, CleanSpace liner was used to seal the earth from the home. The liner was also used to cover the foundation walls and pillars in the crawl space to prevent moisture vapor from the earth from getting into the crawl space.

A SmartDrain was installed in the lowest area of the crawl space to allow water to be returned to the earth. A SaniDry Sedona dehumidifier was also installed in the crawl space to reduce the humidity levels. Moisture collected from the dehumidifier was pumped via a condensate pump to the SmartDrain.

Lowcountry Basement Systems sealed the 22 open crawl space vents to prevent the warm humid air from entering the crawl space. An Everlast CrawlSpace Door, that won’t rust or warp, was installed to prevent air from entering the crawl space.

It took the Lowcountry Basement Systems team three days to complete the job. Deidra was thrilled with the solution.
