Crawl Space Repair Before & After Photos

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.

The Sure-Dry team encapsulates a homeowner's crawl space in Shawano, WI to make it a dry and healthy below grade space.

Before: Musty Smells, Mold & Allergy Issues

At this cottage on Shawano Lake, the homeowners were dealing with constant mildew smells, musty air, and worsening allergy symptoms like itchy, watery eyes. The crawl space beneath the original part of the home was damp, dusty, and likely harboring mold and mildew that was affecting the air inside the cottage—especially after a recent remodel added a second crawl space.

They wanted to make the space safe, clean, and comfortable—especially during lake season.

After: Clean Air, Dry Space & Peace of Mind

We installed a targeted system to address the moisture and mold issues at the source:

• Mold-X™ treatment to kill existing mold and mildew on surfaces

• Sedona SaniDry™ dehumidifier to keep humidity under control year-round

• RimTight® joist insulation to seal out moisture and outside air

• Crawl space vent covers to block humid air from entering

Now the crawl space is dry, treated, and actively controlling humidity—and the indoor air is fresher, cleaner, and healthier.

Before
The homeowner in Shawano, WI had a crawlspace with exposed earth, elevated humidity, and ongoing moisture concerns that were impacting air quality and structural conditions above. Moisture intrusion and unsealed rim joists allowed damp air to circulate throughout the crawlspace, increasing the risk of mold growth, wood deterioration, and cold floors during Wisconsin’s seasonal temperature swings.
Inspection confirmed high moisture levels, poor vapor control, and inadequate drainage protection within the crawlspace.

After
Sure-Dry completed a full crawl space encapsulation using CleanSpace® vapor barrier to fully seal the crawlspace floor and walls, preventing ground moisture from entering the space. A SmartSump® crawlspace sump pump system was installed to manage groundwater, while RimTight® insulation sealed the rim joists to reduce air leakage and improve energy efficiency. To control humidity long-term, a Sedona® dehumidifier was installed to maintain consistent, dry conditions year-round.
The crawlspace is now dry, sealed, and conditioned, improving indoor air quality, energy performance, and long-term protection for the home.
