Crawl Space Support Jacks

Support jacks function like car jacks — using leverage, a jack lifts and holds material above and dispurses the load downward through its base. In crawl spaces, where mid-span support beams can weaken and degrade over time from any number of issues, jacks are used to provide long-term strength to the structure.

SmartJack® crawl space supports are constructed from a galvanized, corrosion-resistant steel, each jack sports a load-bearing capacity of over 60,000 pounds. Our specialists will install secure footings and mountings for each jack, then adjust the jack heights until the beams are fully-supported. We don't just stop at support — under the proper circumstances, SmartJack® can level out sunken floors in your home by returning crawl space joists to their pre-damage positions.

SmartJack® crawl space support jacks have a 25-year, fully-transferrable warranty, which guarantees the integrity of the system for over two decades. With their high-strength construction, support jacks from Lowcountry Foundation and Crawl Space Repair will provide reliable strength and support for your home for many years. If the substrate beneath the jack base sinks due to soil conditions, our expert service technicians can adjust the jacks at any time to ensure they provide the same level of performance throughout the life of your home.

1. First, our teams prepare the work area. This includes cleaning the areas where the support bases will be located, then excavating the soil beneath these locations and filling with support materials to ensure lasting stability.
2. After this is complete, the middle of the crawl space ceiling is located, at which point brackets will be fastened to each of the floor support beams where the support beam will be hung. The galvanized steel beam is hung from the brackets, and the post bases are laid out over the excavated and strengthened base positions.
3. Then, we measure, cut, and install the support posts before tightening them to their desired positions.
4. Finally, we clean the space and leave your home safer and more stable for years to come.

All of this work is typically complete in a single day, and can be performed in crawl spaces of any height, up to and including 10 feet.

In short, whatever you decide to do with your home is entirely up to you. DIY solutions, like stacking cinderblocks under support beams, are almost universally short-term solutions and will need constant replacement and maintenance.

Materials used in DIY crawl space support work are less durable than those offered by Lowcountry Foundation and Crawl Space Repair, and without expert workmanship and quality materials, you may never truly remediate your crawl space sag or deterioration problems.

Furthermore, a sagging crawl space is often caused by a multitude of issues, not simply sagging support beams. Our team will provide a custom-tailored solution, using patented and proven systems to ensure the job is one-and-done.
