Case Study: Stabilizing the Floors in a 1940s Home in Middletown, OH

A steel support jack under a house in a crawl space with dirt, rocks, and foam insulation.

In Middletown, OH, longtime homeowners living in a 1943-built house were growing concerned about increasingly uneven floors. Though no major structural damage was visible, they suspected an issue beneath the surface.

Ohio Basement Authority conducted a full inspection and discovered a sagging main load beam in the crawl space. By installing IntelliJack™ support posts and reinforcing the system with supplemental beams, the team stabilized the foundation and restored the floor’s position—delivering long-term peace of mind in just two days.


The Challenge

  • Uneven floors in a 1940s home
  • Sagging main load beam in the crawl space
  • Old wood posts no longer providing stable support

The Solution

  • IntelliJack™ adjustable steel support posts
  • Concrete footings over compacted stone for long-term durability
  • Supplemental beams added to reinforce main structure

The Impact

  • Floors raised back toward their original position
  • Crawl space stabilized with permanent, rust-resistant posts
  • Homeowners regained confidence in their home’s structural integrity

Before Crawl Space Repair:

Crawl space with a plastic vapor barrier on the ground and sagging wooden beams overhead.

Structural Weakness

The homeowners had lived in their 1943 home for over two decades and recently began noticing uneven, sloping floors. A full inspection by Ohio Basement Authority revealed the problem: a sagging main load beam in the crawl space, caused by undersized joists and deteriorating wood posts. These aging supports had shifted over time, failing to carry the home’s weight properly—leading to serious concerns about structural stability if left unaddressed.

After Crawl Space Repair:

Metal support jack on a concrete footing under a wooden beam in a crawl space with exposed dirt and insulation.

Stabilization with IntelliJack™ Posts

Ohio Basement Authority designed a targeted stabilization plan. IntelliJack™ posts—cut to fit the crawl space height—were placed beneath the sagging load beam and on top of supplemental beams to maximize support. Each post was mounted on a concrete footing set over compacted stone to ensure it wouldn’t shift or settle. The threaded design allowed for precise lifting, and galvanized steel construction meant these posts would never rust or fail like wood.

Called Ohio basement authority and had Mark Overmyer at my door the next day. He evaluated our problem and found that it was a plumbing issue and not something they handle. Even though,he was great and checked out the basement and foundation. Prompt and friendly service. Very professional. Would recommend!
