Damp Crawl Space with Sagging Floors Fixed in Shiocton, WI

Before
The homeowner in Shiocton, WI was experiencing ongoing crawl space moisture issues, including damp soil, elevated humidity, and signs of sagging floors above the crawl space. Seasonal groundwater and Wisconsin freeze-thaw cycles allowed moisture to collect beneath the home, contributing to musty odors, inefficient insulation performance, and concerns about long-term structural support. The crawl space lacked a reliable drainage and pumping system, and the existing supports were insufficient to stabilize the floors.

After
Sure-Dry completed a full crawl space encapsulation and stabilization solution designed for long-term moisture control and structural support. A SmartSump crawl space sump pump system was installed to manage groundwater, paired with a secondary SuperSump® system for added pumping capacity and redundancy. The crawl space was fully encapsulated using CleanSpace® vapor barrier along the floor and walls, while RimTight® insulation sealed the rim joists to reduce air leakage and moisture intrusion. To address floor sagging, adjustable SmartJack® support posts were installed and properly load-tested to stabilize and lift the structure. A Sedona® crawl space dehumidifier was added to control humidity and improve air quality.
The crawl space is now dry, sealed, and structurally supported, improving energy efficiency, indoor air quality, and long-term protection for the home.
