Before Crawl Space Repair:

Moisture in the Crawl Space
As you can see in the image, the crawl space had no proper moisture control and has standing water. Without a sealed system, humidity levels stayed high, putting the home at risk of mold, rot, and musty odors.

Sinking Floors
Our inspection revealed significant differential settlement, which led to structural instability and interior wall cracks. They also observed unreliable support systems, as you can see in this photo.
This type of sinking can pose a risk to the home’s stability.
After Crawl Space Repair:

IntelliJack™ Support Jacks
To stabilize the foundation, our crew installed 14 SettleStop IntelliJack™ crawl space jacks. These steel supports are perfect for mobile homes with mixed crawl space floors, whether concrete or dirt.
You can see how they’re spaced evenly to provide lift and long-term stability where settlement was most severe.

Crawl Space Drainage
Our team installed a drainage system designed to capture groundwater before it spreads.
The system channels moisture directly toward the new discharge point to keep the area dry.
HOA-related delays threatened to delay the project, but our team worked to secure approvals and move forward efficiently.
