What Are Crawl Space Support Jacks?
Crawl space support jacks are adjustable steel posts installed beneath the home to provide additional support where floors are sagging or deflecting. Set on proper footings and positioned under beams or joists, they reduce span and restore stability to the floor system.
Once installed and adjusted, they provide permanent support to prevent further sagging and improve the overall strength and performance of the structure.
Signs You Need Crawl Space Support Jacks
Sagging or bouncy floors are a common sign that the structure beneath the home is not adequately supported. Over time, long spans or minor movement can cause the floor system to deflect, leading to noticeable dips, movement, and even cracking in interior walls.
Common signs include soft or bouncy areas, uneven floors, wall or drywall cracks, gaps at baseboards, and doors or cabinets going out of level—indicating the need for added support to stabilize the structure and prevent further movement.
What Causes Structural Settlement?
Structural settlement within the home is often caused by long spans, undersized framing, or gradual movement over time. As wood framing carries load, it can slowly deflect, especially in older homes where materials have taken a permanent set.
Moisture in the crawl space can accelerate this process by softening the wood and reducing stiffness, leading to sagging floors, wall cracks, and doors going out of level.
How Crawl Space Jacks Fix The Problem
Crawl space support jacks fix sagging floors by adding structural support beneath the home where it is needed. Installed under beams or joists, they reduce the span of the framing and transfer the load to properly supported footing points, helping to stabilize the floor system.
By reinforcing these areas, support jacks stop further sagging and improve the overall strength and feel of the floor. In many cases, they also allow for slight correction of dips, creating a more stable and level surface over time.
How Are Crawl Space Jacks Installed?
Crawl space support jacks are installed by excavating beneath the home to reach stable soil, typically 12 to 18 inches deep, and placing a proper footing to support the load. The jacks are then set on the footing and positioned under beams or joists where support is needed.
Once installed, the jacks are adjusted to stabilize the floor system and provide permanent support, helping prevent further sagging and movement.
