Our smart jack system provides reliable support for sagging and undersized beams, restoring stability and straightness to sagging floor joists in a crawl space.


At Thrasher Foundation Repair we use the Supportworks system, SmartJack(R) that we use supports posts that can correct problems such as sloping and overly springy floors, interior wall cracks, and out-of-level door frames once installed in your crawl space.

The SmartJack(R) can be adjusted over time to provide additional straightening and leveling action if necessary because of its design.

The SmartJack(R) is also compatible with a crawl space vapor barrier system, allowing you to address crawl space mold and humidity issues while repairing your structural problem.

To be stable, firm, and level, the floor above a crawl space requires reliable mid-span support that's usually provided by a post-and-beam assembly.

But beams are often undersized, and many contractors use wooden posts that can rot, shift and settle. When this happens, floor joists sag, and other structural problems occur. The SmartJack(R) system is a foundation repair product that provides a permanent solution to these problems.

Customers tell us all the time that when they have a trampoline effect or floors that make a lot of noise, they don't know what to do. Once you've seen what the SmartJack system can do, you'll know that there is only one right way to fix your crawlspace floor system.

There are a couple of main reasons that your floors might be sagging, columns/footings that are sinking, settling, or leaning. When you are in your crawlspace, you might see shims underneath to help the gap between the beam and column, like that is going to help your sagging floors. Columns that might be spaced too far apart can sag in-between them causing a bounce or creaky floor. Whenever in a crawlspace, moisture is always a topic of conversation. When the wood floor joist, beams, and subfloor get excessive moisture, the wood will weaken and cause the wood to bend or start to rot.
