Crawl Space Repair Before & After Photos

In Conover, WI, a homeowner faced a grave concern with their crawlspace - it was a damp and neglected space, hampering the home’s comfort and safety. As you can see in the 'before' photo, it was a perfect breeding ground for mold and mildness. Recognizing the urgency, we deployed our CleanSpace solution, transforming the area into a dry, clean, and significantly healthier space. Notice in the 'after' photo how CleanSpace encapsulation works to seal off moisture, bringing peace of mind and a solid foundation back to the home. Our commitment at Sure-Dry is to not just fix the problem but to ensure your home stands safe and resilient for years to come.

As shown in the before photo, a moisture-laden crawl space in Conover, WI, was causing mold growth and other structural issues for a homeowner. Sure-Dry was recommended to resolve these problems. We transformed this space by installing CleanSpace Vapor Encapsulation and Drainage Matting, ensuring proper water management. The SaniDry Sedona Dehumidifier provided an efficient moisture solution, while SilverGlo wall insulation and RimTight Joist Insulation effectively sealed air leaks, enhancing energy efficiency. The after photo highlights the result—an ultra-clean, dry crawl space that safeguards the home’s structural integrity and provides lasting peace of mind.

Before
A homeowner in Shiocton, WI was struggling with uneven, sunken concrete surfaces around their property — including a driveway and garage slab — that created tripping hazards, poor drainage, and continued settlement. Cracks and open joints in the concrete made the situation worse by allowing water to infiltrate beneath the slab, eroding soil and undermining support. Traditional repair approaches (like replacing concrete) were costly and disruptive, and simple patching with DIY sealants would likely fail in Wisconsin’s freeze-thaw conditions.

After
Sure-Dry performed a professional concrete restoration using PolyLevel® Injection Foam to lift and stabilize the settled slabs. PolyLevel’s high-density polyurethane foam was injected beneath the concrete to fill voids and raise the surface back to its proper level, restoring safe, functional concrete with minimal downtime. After leveling, all joints and cracks were sealed with NexusPro® Joint Sealant, a flexible, silicone-based sealant that provides long-lasting protection against water intrusion and resists cracking or drying out in harsh weather. The concrete surfaces are now level, structurally sound, and better protected from future soil erosion and moisture damage, giving the homeowner a durable, long-term repair solution. 

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.
