Crawl Space Structural Support Jacks
what are Crawl Space Jacks?
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. But beams are often undersized, and many contractors use wooden posts that can rot, shift and settle. When this happens, floor joists sag and other structural problems occur. The SmartJack® system is a foundation repair product that provides a permanent solution to these problems. Once installed in your crawl space, SmartJack® support posts can correct problems such as sloping and overly springy floors, interior wall cracks, and out-of-level level door frames.
The SmartJack® 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.
Signs To Look Out For!
Weak or Rotting Floor Joists and Beams
Weak or Rotting Floor Joists and Beams
High humidity and moisture in crawl spaces can lead to wood rot, mold, and mildew, which weaken wooden floor joists and support beams. This deterioration causes the wood to lose its strength and sag under the weight of the floor above.
Moisture and Humidity
Moisture and Humidity
Uncontrolled moisture in a crawl space, often from poor drainage, plumbing leaks, or lack of a vapor barrier, contributes to wood rot and allows for fungal growth that damages wooden structural components.
Fungus and Mold Growth
Fungus and Mold Growth
These organisms thrive in damp environments and directly feed on and break down wood, severely compromising its structural integrity.
Crawl Space Support Post Settlement
Crawl Space Support Post Settlement
Existing support posts (often concrete blocks or wooden posts) may settle or sink into the soil if the soil beneath them is weak, poorly compacted, or has experienced changes in moisture content.
Inadequate Support
Inadequate Support
Sometimes, the original construction may have had too few support posts, or the spans between supports were too wide for the load, leading to gradual sagging over time.
Termite or Pest Damage
Termite or Pest Damage
Termites and other wood-boring insects can significantly damage floor joists and beams, leading to structural weakening and sagging.

The Best Solution For The Problem
The SmartJack® crawl space system provides solid support for sagging and undersized beams, restoring stability, and straightness to sagging floor joists in a crawl space.
SmartJack® Crawl Space Support System
- The SmartJack® system consists of heavy-duty, galvanized steel support jacks that are installed directly beneath sagging floor joists or beams in your crawl space.
- These adjustable jacks connect to a pre-cast concrete footing or solid engineered fill that extends to stable load-bearing soil, ensuring long-term stability.
- They are designed to permanently lift and stabilize sagging floors, and can be adjusted over time to fine-tune the leveling of the floor above.
- Made from corrosion-resistant steel, the SmartJack® system is built to last and provides a stable alternative to unreliable concrete block piers.
Our Process for Installing SmartJacks®
Thorough Crawl Space Inspection
Our crawl space repair specialists conduct a detailed inspection of your crawl space, identifying the cause of the sagging floors, assessing the condition of joists, beams, and existing supports, and checking for moisture, mold, or wood rot.
Customized Repair Plan
Based on the inspection, we design a tailored solution. This plan will specify the optimal placement and number of SmartJack® supports needed, along with recommendations for any necessary wood repair, replacement, or crawl space encapsulation.
Site Preparation
In the crawl space, a stable footing is prepared beneath each proposed SmartJack® location. This may involve excavating and pouring a small concrete footing or creating a solid engineered fill.
SmartJack® Installation
The galvanized steel SmartJack® supports are assembled and installed on the prepared footings beneath the sagging girders or joists.
Floor Stabilization & Lifting
Once installed, the SmartJack® supports are carefully adjusted to provide immediate stabilization to the floor system and, in many cases, can gently lift the sagging floors back toward their original level position.
Wood Repair/Replacement (if needed)
If wood rot or extensive damage is present, our team will perform necessary wood sistering, reinforcement, or replacement of joists and beams to restore full structural integrity.
Crawl Space Encapsulation (recommended)
To prevent future moisture issues and wood deterioration, we highly recommend combining the structural repair with a full crawl space encapsulation system, including a vapor barrier, dehumidifier, and proper drainage.
