Crawl Space Floor Joist Jack System - SmartJack


Crawl Space Repair Solutions

SmartJack™ Floor Joist Jacks

Sagging floor joists or beams in your crawl space indicate serious structural problems for your home. Excessive moisture in your crawlspace can cause the soils under your home to shift, causing your floor joist to sag, buckle and become uneven.

The SmartJack™ System can be installed in less than a day and will lift and stabilize sagging floors without messy concrete. SmartJacks are so strong that each jack can support over 60,000 pounds - that’s more than the weight of 7 elephants!

- How NOT To Fix Your Sagging Floors

Trying to repair your sagging floors by yourself may be unsafe and will only serve as a temporary solution. Light duty jacks from your local home store are not designed to carry the weight of your home. Here are some examples of what not to do!

Don't Use Concrete Columns!

Concrete Columns

Concrete columns are NOT adjustable and would only need to be shimmed later on, which is also just a temporary and unsafe fix to sagging floors. It's also difficult to form and pour concrete in your crawl space. We do not recommend this repair method.

Shimming Your Floor Joists

Shimming Your Floor Joists

Once again, shimming is only a temporary fix, and doing so will not lift your floors and support your walls.

Installing Light Duty Jacks

Using Light Duty Jacks

Light duty jacks have very limited capabilities, are difficult to adjust, and do not address problems with the soil. If you install a jack improperly or the soil isn't able to support the weight of your home, you'll end up with damaged floor joists or even collapsed floors.


- SmartJack™ System Is The Answer!

To fix your sagging floors permanently, we use the patented, affordable and easy to install SmartJack™ System. This system has been designed and engineered by geotechnical and structural engineers, so you can rest assured that your home is safe and secure!
