The SmartJack® crawl space support system

SmartJack® logo

To be stable, strong, and level, the floor above a crawl space requires solid mid-span support that's usually provided by a post-and-beam assembly. Unfortunately, beams can be undersized, and wooden posts can rot, shift and settle. When this happens, floor joists sag and other structural problems occur.

The SmartJack® system provides a permanent solution to these problems. It is also compatible with crawl space encapsulation systems, making it a good choice for homeowners wishing to eliminate moisture problems and improve home energy efficiency, while also solving structural problems.

Other services TerraFirma provides include:

  • Installing exterior crawlspace access
  • Crawlspace water and moisture problems
  • Repairing or replacing wood rot, pest damage, and undersized materials
  • Clean out of debris and soiled insulation
  • Seismic upgrades
  • Crawlspace code compliance issues
