What Are House Jacks?
House jacks are adjustable steel support posts designed to stabilize sagging floors by reinforcing weakened floor joists and beams from beneath your home. Installed in a crawl space or basement, they carry structural loads to a stable foundation beneath your home.
Unlike temporary jack posts or wood supports, engineered house jacks serve as a long-term structural repair. They help reduce floor movement, improve stability and, in many cases, lift sagging floors closer to their original position.
No two homes are the same, so the right repair starts with a thorough inspection. We'll look at your floor framing, crawl space conditions and structural supports to determine whether house jacks are the right solution for your home.
What Causes Crawl Space Structural Damage?
Crawl space structural damage often develops slowly as moisture, shifting soils and aging materials weaken the floor support system beneath your home. Excess humidity, poor drainage, freeze-thaw cycles and older vented crawl spaces can all lead to wood deterioration, settling support posts and unstable soil. Over time, these conditions may leave floor joists and beams without adequate support, resulting in sagging, uneven or bouncy floors.
Our Crawl Space Support Solution
Every sagging floor has an underlying cause, so every repair begins with a thorough structural inspection. If weakened floor supports are behind the problem, we’ll recommend a permanent solution designed to stabilize your home’s floor system for the long term.
