Crawl Space Support in the Southeast
what are Commercial Crawl Space Jacks?
Commercial buildings with crawl spaces depend on strong mid span support to keep floors stable and level. In many older properties, beams are undersized or supported by wood posts that can rot, shift, or settle. As these supports weaken, floors begin to sag, walls crack, and doors and frames fall out of alignment. Tenants and occupants may notice sloping or bouncy floors, especially in high traffic or heavily loaded areas.
SmartJack® is a commercial grade crawl space support system designed to correct these issues. Adjustable steel posts are installed beneath the structure to reinforce or replace failing supports and transfer loads to more stable soil. The system can lift and stabilize sagging floor framing and is compatible with crawl space encapsulation systems, allowing structural repairs and moisture control to work together in one coordinated solution.
Signs To Look Out For!
Weak or Rotting Floor Joists and Beams
Weak or Rotting Floor Joists and Beams
In commercial buildings, crawl spaces often support large open floor plans, storage areas, or heavy foot traffic. When humidity and moisture are present, wooden joists and beams can begin to rot or decay. As the wood weakens, it loses its ability to carry structural loads. This can lead to sagging floors, uneven surfaces, and visible deflection across longer spans. Over time, structural performance declines and repairs become more extensive.
Moisture and Humidity
Moisture and Humidity
Uncontrolled moisture is a common issue in commercial crawl spaces. Poor exterior drainage, plumbing leaks, or the absence of a proper vapor barrier can allow damp conditions to persist. Excess moisture softens wood components and accelerates deterioration. In commercial settings, this not only impacts structural stability but can also affect indoor air quality and tenant comfort.
Fungus and Mold Growth
Fungus and Mold Growth
Damp, enclosed crawl spaces create ideal conditions for mold and wood destroying fungus. These organisms feed on wood fibers, breaking down structural members from the inside out. As the damage progresses, floor framing can lose significant strength. Business owners may notice sagging floors, musty odors, or signs of surface growth along joists and beams.
Settlement of Existing Support Posts
Settlement of Existing Support Posts
Many commercial properties rely on concrete blocks, stacked masonry, or wood posts for mid span support. If the soil beneath these supports is weak, poorly compacted, or affected by moisture changes, the posts can sink or shift. When settlement occurs, the load above is no longer evenly distributed. This results in uneven floors, cracks in walls, and misaligned doors and frames throughout the building.
Inadequate Support
Inadequate Support
Some commercial buildings were constructed with wide beam spans or too few support points. As building use changes or loads increase over time, the original support system may no longer be sufficient. Gradual sagging, noticeable floor slope, and vibration under foot traffic are common signs that additional structural reinforcement is needed.
Termite or Pest Damage
Termite or Pest Damage
Termites and other wood destroying insects can cause significant damage to floor joists and beams in commercial crawl spaces. As pests hollow out wood members, structural capacity is reduced. Left unaddressed, this damage can contribute to sagging floors and unsafe conditions for occupants and customers.

The Best Solution For The Problem
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.
Commercial SmartJack® Process
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.
