5-Star Crawl Space Floor Supports in AL & TN | The Crack Guys
Do your floors bounce when you walk across them? Do you notice a sag or slope in certain areas of your home? These are not just cosmetic issues — they are warning signs of a structural problem beneath your feet that will only get worse over time without the right crawl space floor supports in place.
At The Crack Guys, we install the Samson Floor Support System — a permanent, adjustable steel support solution that restores level, stable floors from the crawl space up. We serve homeowners across Alabama and Tennessee from five locations, and our specialists diagnose and fix sagging floor problems every day.
What Causes Sagging or Bouncy Floors?
Sagging and bouncy floors are almost always caused by problems inside your crawl space. The most common causes include:
Inadequate Support Spacing — When the distance between concrete block piers is too great, floor girders and joists sag under the weight of the home above.
Moisture Damage and Wood Rot — Damp crawl spaces promote mold, fungus, and wood decay that weakens structural members over time. Once wood begins to rot, it loses its load-bearing capacity and floors above start to sag.
Soil Settlement — Soil beneath the crawl space can shift and settle over time, causing the piers or footings below your floor system to sink and lose contact with stable ground.
Improper Original Construction — Some homes were built with inadequate materials or support spacing that was never sufficient to properly carry the floor load above.
Common signs that you need crawl space floor supports include bouncy or soft spots when walking, visible slopes or dips in your floor, cracks appearing above doorways, doors that stick or no longer close properly, and musty odors coming from below.
What Are Crawl Space Floor Supports?
Crawl space floor supports are adjustable steel support columns installed beneath your floor girders in the crawl space. They transfer the weight of the floor system to stable ground through precast concrete footers — permanently restoring the level, stable floors your home was designed to have.
The Crack Guys use the Samson Floor Support System — a heavy-duty, adjustable steel support designed specifically for crawl space environments. Unlike wood posts that rot and concrete blocks that shift, the Samson system is built to last and can be precisely adjusted to achieve a perfectly level floor.
The Samson Floor Support System — How It Works
The Samson Floor Support System addresses sagging floor problems by providing permanent, adjustable support directly beneath your floor girders. Here is a step-by-step breakdown of the installation process:
Step 1 — Crawl Space Inspection Our specialist thoroughly inspects your crawl space to identify all areas of sagging, inadequate support, moisture damage, and wood rot. We document our findings with photos and measurements so you can see exactly what we see.
Step 2 — Preparing the Crawl Space Technicians dig holes in the dirt floor of your crawl space directly beneath the sagging girders. These holes are spaced evenly along the length of the girder and sized to accommodate precast concrete footers.
Step 3 — Installing Precast Concrete Footers Round precast concrete footers are placed into the holes, positioned directly beneath the girders. These footers provide a stable, load-bearing base for the Samson supports above.
Step 4 — Placing the Samson Floor Supports Samson Floor Supports are placed on top of each concrete footer and extended up to meet the bottom of the sagging girder. Technicians make final adjustments to ensure each support is properly positioned and plumb.
Step 5 — Lifting and Leveling Using a large wrench, technicians turn the adjustable screw on each Samson Floor Support — gradually raising the girder and the floor above it back toward level. This is done carefully and incrementally to avoid stressing the structure above.
Step 6 — Mid-Span Joist Support (If Needed) For homes where individual joists are sagging between girders, additional floor supports are installed beneath a wood drop beam that spans across multiple joists — lifting them all simultaneously back to level.
Step 7 — Final Inspection Technicians confirm the stability and levelness of the floors above, check all supports for proper installation, and clean up the work area before leaving.
Why Choose the Samson Floor Support System?
The Samson Floor Support System is one of the most effective and reliable crawl space floor support solutions available for Alabama and Tennessee homeowners. Here is why:
Permanent Solution — The Samson system stabilizes your floor from below and prevents further sagging. Unlike temporary shimming or wood post repairs, the Samson supports are designed to last for the life of your home.
Adjustable Design — The threaded steel adjustment mechanism allows for precise leveling — and can even be adjusted in the future if additional settling occurs.
Heavy-Duty Construction — Each Samson support is engineered to carry significant floor loads without bending, buckling, or deteriorating over time.
Addresses the Root Cause — By installing supports on stable concrete footers, the Samson system transfers load directly to stable ground — solving the underlying structural problem rather than masking the symptoms.
Minimal Disruption — The entire installation takes place in your crawl space. There is no need to remove flooring, cut into walls, or disrupt your living space above.
Should I Also Address Moisture in My Crawl Space?
In most cases, yes. Moisture is one of the leading causes of sagging floors — because it leads to wood rot, mold, and structural weakening over time. Installing crawl space floor supports addresses the structural problem, but if moisture is the underlying cause it will continue to damage your floor system unless it is also resolved.
The Crack Guys recommend combining crawl space floor supports with our crawl space encapsulation service to seal out moisture permanently. For crawl spaces with active water intrusion, our crawl space waterproofing service installs an EZflow drainage system and sump pump to manage water before it causes further damage.
According to the American Society of Home Inspectors, sagging floors are among the most commonly identified structural issues during home inspections — and addressing them early prevents far more costly repairs down the road.
