Crawl Space Support Posts
When floors in the home start to sag, this may not be a foundation issue but a possible problem in the crawl space underneath. Homeowners in Oregon and Washington are very familiar with the damage our wet, damp, and expanding soils do to our homes. If left unchecked, these conditions can lead to wood rot, mold growth, and pest infestations, further weakening the structural integrity of the crawl space. Poor ventilation and trapped moisture exacerbate these issues, creating an unhealthy environment that can impact indoor air quality. Proactively addressing these problems with crawl space support posts not only protects your home but also ensures a safer, more comfortable living space.
SmartJack®
THE SMARTJACK SYSTEM stabilizes crawl space beams and floor joists. It’s the ideal solution to lift the floors above the crawl space toward their original elevation and reduce floor “bounce” caused by weakened floor joists or excessive spans. The SmartJack system addresses weak foundation soils by creating a solid base of foundation support posts to distribute the weight of your home. Galvanized steel columns are cut to length, set on a cast aluminum footing, and secured to existing girders or supplemental beams with adjustable top brackets. The heavy-duty threaded rods of these crawl space support posts allow for adjustment and can even lift sagging and sloping floors.
