Before you start looking for DIY solutions for your home’s uneven floors, it’s a good idea to call a foundation repair contractor for a proper inspection of your home’s structural stability. Although a sloping or uneven floor may seem like a minor problem, it’s often a sign of underlying foundation, crawl space, or soil issues. As your home continues to settle or incur water damage, these foundation issues will only get worse, costing you more money in the long run.

At AquaGuard, we offer Northern Georgia and area homeowners free foundation inspections, during which we can help you diagnose what’s causing your uneven floors and provide effective, permanent options for floor leveling. 

How Do I Know My Floor Needs Leveling? 

Uneven floors can be difficult to spot, and most homeowners don’t discover them until they’re replacing their flooring with hardwood or tile. However, when it comes to sagging or sloping floors, being proactive could mean the difference between minor and major structural repair. For that reason, we provide homeowners with free inspections so they can catch signs of foundation or crawl space damage when it’s easiest—and least expensive—to fix. 

Telltale Signs of Uneven Floors

Wondering when it’s time to call a foundation repair expert? Here are some telltale signs of uneven floors: 

  • Floors that feel soft or bouncy
  • Sinking or heaving concrete slabs
  • Floor cracks
  • Floors noticeably slope or sag

If you notice any of the above signs, call AquaGuard today for a free inspection in Northern Georgia and the area!

What Causes Uneven Floors?

Uneven floors can be caused by a variety of factors, including poor support design, crawl space damage, and foundation damage. Each cause comes with a different solution, so it’s important to know exactly what’s causing your uneven floors before spending money on a floor leveling product or service. 


If the framework of your home was poorly constructed, you’ll likely feel the repercussions through uneven floors. If columns are spaced too far apart, you may notice your floor sags or see gaps between the floor and wall.  

Water damage within your crawl space can cause support beams to deteriorate. When this happens, you may notice the floor on the first level of your home sagging, creaking, or feeling bouncy.

If the soil beneath your home is unstable and begins to shift, your house will settle unevenly. This uneven settlement, known as differential settlement, can cause sloping floors and significant foundation damage.

Floor Leveling Solutions

Uneven floors are rarely caused by issues with the floor itself. When uneven floors are caused by issues such as foundation and crawl space damage, simply using a self leveler won’t permanently resolve the problem. At AquaGuard, we’ll help you diagnose exactly what’s causing your uneven floors, then provide floor leveling solutions that actually get to the root of the problem. 

Unlevel Floor Above a Crawl Space

The Problem

The floor joists above a typical crawl space and supported by the perimeter walls of the crawl space foundation, and by a post or column-and-beam framework that extends down the center of the crawl space. Although the perimeter walls of a crawl space can settle or shift to cause floor problems above (such as uneven or sinking floors), it’s more common for the center support system to settle or sag because it wasn’t properly built in the first place. A center post-and-beam support system can also weaken and settle because moisture in a dirt-floored crawl space has caused wood supports to rot and collapse. As crawl space structures begin to sag, the floor above will sag in turn.

The Solution

At AquaGuard Foundation Solutions, we can quickly and effectively repair a crawl space structural issue with our heavy duty crawl space jacks.

Crawl space jacks are adjustable steel posts that will stabilize sagging crawl space structures, and consequently, repair uneven or sinking floors. During installation, we prepare a base of compacted engineered fill at all jack placement points, located directly beneath the main support beam.

We install a pre-cast concrete base on this fill, and then extend a crawl space jack between the base and the beam. Once each jack’s threaded rod is adjusted beneath the post, the weight bearing on the beam is transferred to the soil below. Additionally, this system allows the contractor to push a sagging floor back toward its original level position.

Our warrantied crawl space jacks can effectively stabilize your crawl space—usually in a day.

Leveling Basement Floors

The Problem

Since masonry is more likely to break than bend, concrete floors that are uneven are generally cracked and/or broken as well. If your foundation is settling, it may be lifting the concrete floor as the rest of the foundation experiences movement. There are also times when the slab floor can lift or sink independently of these walls. Concrete slab floors crack and settle when the soils underneath them shrink, settle or wash away. Likewise, a concrete slab will lift, or “heave”, when the soils underneath expand. A concrete slab can move independently of adjacent foundation walls, or along with them. Since settlement isn’t uniform, one section of a slab may be elevated as another section sinks down.

The Solution

Slab floors that are sinking independently of the walls can be repaired with a slab pier system, shown on the right. These piers are placed in cored holes on the floor, extending down to competent soils to hold your floor in place. They can even be used to lift a slab back to its original, level position. If the floor is cracked and uneven because of foundation settlement, then your contractor will recommend either foundation push piers or helical piers to stabilize the entire foundation. Foundation piers can also be used to lift the foundation to its original position in some cases. Foundation heave is a complicated and multifaceted problem that requires a professional inspection.
