Sagging floors, bouncy rooms, and interior wall cracks are often signs of a bigger problem beneath your home. In many cases, these symptoms stem from weakened or improperly supported floor joists within the crawl space. Over time, moisture, shifting soil, and poor construction can cause these supports to fail — putting your home’s structural integrity at risk.
That’s where the SmartJack® Crawl Space Support System comes in.
What is SmartJack®?
SmartJack® is an adjustable steel support column specifically engineered to stabilize and, in many cases, lift sagging crawl space floors. Unlike traditional concrete block or wood shims, SmartJack® is built to resist corrosion, handle heavy loads, and provide long-term, adjustable support to compromised joists and girders.
The system is installed on engineered base pads that distribute weight across a broad area of soil, reducing the risk of settlement. Once secured, the SmartJack® can be adjusted to restore floor height and improve structural alignment.
Setting Realistic Expectations:
While SmartJack® is highly effective at stabilizing and lifting floors, results will vary depending on how far the floor system has dropped and whether the wood framing has sustained permanent damage. In cases of extensive wood rot, additional repairs may be necessary before SmartJack® installation.
Even when a full lift isn’t achievable, SmartJack® provides critical stabilization that halts ongoing movement and prevents further structural stress.
