Crawl Space Repair Before & After Photos

Before: Damp, Dirty, and Inefficient

In Montello, WI, a homeowner contacted Sure-Dry after discovering that their crawl space was damp, musty, and visibly moldy. Cold floors in the winter and high humidity levels throughout the year were also making the home uncomfortable and energy-inefficient.

The crawl space had exposed soil, falling insulation, and air leaks around the rim joists—creating the perfect environment for moisture buildup, wood rot, and poor indoor air quality.

After: A Clean, Dry, and Energy-Efficient Crawl Space

Sure-Dry designed and installed a complete crawl space encapsulation and dehumidification system that included:

• CleanSpace® Vapor Barrier: A durable, bright white liner installed along the floor and walls to seal out ground moisture and create a clean, usable space.

• RimTight™ Spray Foam Insulation: Applied to rim joists and sill plates to stop air leakage and heat loss.

• SaniDry™ Sedona Dehumidifier: Installed to maintain optimal humidity levels year-round and prevent mold growth.

The transformation was immediate. The space is now dry, mold-resistant, energy-efficient, and significantly healthier for the entire home above.

Before:
A new homeowner in Coloma, WI noticed consistently elevated humidity in their previously encapsulated crawl space, despite the vapor barrier being intact and properly sealed. Hygrometer readings showed moisture levels nearly 40% higher than recommended, contributing to musty odors and discomfort in the upper living space. Seasonal humidity patterns across Waushara County—combined with limited air movement under the home—were allowing moisture to stay trapped in the crawl space even with encapsulation in place.

After:
To correct the issue, the crew installed a SaniDry™ dehumidification system sized specifically for the crawl space’s air volume and layout. Once operational, the system rapidly removed excess moisture, reducing humidity levels by approximately 40% within the first cycle range. The homeowners experienced immediate relief in both smell and overall indoor comfort, with system readings showing stable, controlled humidity throughout the crawl space.
The space is now properly conditioned, protected from moisture buildup, and functioning as intended within the encapsulation system.

Before:
A homeowner in Hancock was dealing with serious crawl space concerns. The dirt floor allowed moisture and odors to rise into the home, wooden beams were showing signs of stress, and the space lacked insulation. The combination of high humidity, poor energy efficiency, and weakened support left the homeowner looking for a complete, permanent solution.

After:
Our team transformed the crawl space with a comprehensive system. The area was sealed with the CleanSpace® vapor barrier to block out ground moisture. We installed SilverGlo® insulation panels along the crawl space walls to improve energy efficiency and reflect heat back into the home. To address sagging beams, we added SmartJacks® for strong, adjustable support.

Finally, we installed a Sedona dehumidifier to keep humidity under control and protect the entire space from mold and rot.

Now, the crawl space is dry, stable, energy-efficient, and healthy — protecting the home’s foundation while making the living space above more comfortable year-round.

In Markesan, WI, this crawl space was facing moisture issues, contributing to a musty environment and potential structural damage. The before photo shows a typical damp and unsightly space requiring attention. To resolve this, we employed our CleanSpace, Drainage Matting, and RimTight insulation solutions. In the after photo, notice how the CleanSpace liner now seals the area, protecting it from mold and mildew. The Drainage Matting ensures proper water flow beneath the encapsulation, while RimTight insulation prevents moisture infiltration and enhances energy efficiency. With our proven systems, we transformed the crawl space into a clean and dry area.

In Fox Lake, WI, a homeowner faced a malfunctioning crawlspace sump pump, turning their crawl space into a worrisome water trap. As you can see in the before photo, the urgency for a solution was clear. Enter Sure-Dry: we rose to the occasion with our SuperSump and CleanSpace installation. Notice in the after photo the dramatic transformation— a dry, clean, and water-resistant space. Now, the homeowner enjoys peace of mind, thanks to a reliable solution that stands the test of time
