Case Study: Crawl Space Repair for a Sinking Mobile Home in Philadelphia, PA

A homeowner in Philadelphia noticed her mobile home was sinking on one side and contacted Groundworks for help.

Our inspection revealed significant foundation settlement and a flooded crawl space, both threatening the home’s stability. We installed crawl space jacks to lift and support the structure, and added a crawl space drain to address the unexpected water intrusion.


The Challenge

  • A homeowner in Philadelphia, PA, noticed her mobile home was sinking.
  • She also has unexpected flooding in her crawl space.

The Solution

  • Groundworks installed 14 SettleStop IntelliJack™ crawl space jacks.
  • A crawl space drain was installed.

The Impact

  • The homeowner was relieved to have both the sinking and water issues addressed at once.
  • She appreciated the team’s responsiveness and the seamless addition of drainage to the project.
  • The home is now level, dry, and protected for the future.

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.
