What Causes a Sagging Floor and How Can It Be Repaired?
A sagging floor is a sign that the “bones” of your home are damaged or deteriorating. Addressing these issues early is essential to minimize repair costs and prevent further damage. In our experience, issues like warped or bowed floors often stem from problems with the subfloor, floor joists, or foundation.
At Acculevel, we’ve been repairing sagging floors, warped floors, bowed floors, and structural wood flooring systems since 1996. Our team also specializes in subfloor repair near you, ensuring that your floors are strong, even, and built to last.
What Causes A Slab Floor To Sag?
Unlike homes with basements or crawl spaces, a slab foundation features a solid concrete floor with no structural wood flooring system. For homes with this type of foundation, unstable soil, poor compaction, or erosion issues are often the primary culprits. Once the soil becomes compromised, the slab may shift, resulting in the sagging floor effect or a noticeable sinking appearance.
Pressure from these shifts can sometimes crack the slab itself, leading to uneven floors with high and low spots. To fix this type of damage, professional concrete slab repair or foundation leveling may be required. To fix this type of damage, you need concrete slab repairs.
Floor Joist Repair Near You – Causes of Sagging Basement or Crawl Space Floors
For basements and crawl spaces, the range of potential issues is considerably larger due to their structural wood flooring systems.
If you notice sagging floors, the most common culprit is damage to the support structure, requiring floor joist repair near you to restore stability and strength.
Water Damage
Water intrusion is one of the leading causes of structural issues because it seeps into the ground around your foundation, putting the sill plate, floor joists, and wood beams at risk. Because they often come into direct contact with concrete or exposed soil, they are especially vulnerable to rot, swelling, and decay caused by prolonged moisture exposure. Once weakened, the floor system fails, resulting in sagging and uneven surfaces.

Humidity
Even without standing water, high humidity levels can damage the beams, joists, and subfloor. Wood is porous and absorbs moisture from the air, leading to gradual weakening and rot. As the wood decays, it compresses under the weight of your home, often lowering the floor by several inches. In these cases, floor joist repair or beam reinforcement may be necessary to restore structural integrity.
Insect Damage
Pests such as termites and powderpost beetles can wreak havoc on your home’s wood framing system. Termites, along with certain beetle species, bore into beams and joists, weakening the structure from within. These insects lay eggs inside wooden supports, and infest your structural wooden flooring system, compromising its strength. This may require extensive structural wood repair to address the damage.
Human Error
Human error is another possibility. Retrofits for plumbing, electrical, or HVAC systems sometimes lead to cut joists or notched beams. These modifications create weak points in the structure, increasing the risk of splitting, sagging, or even collapse. Identifying and reinforcing these areas through joist repairs and beam stabilization can prevent long-term structural issues.
Aging Home and Outdated Building Codes
Older homes often lack modern structural standards, with support beams or posts spaced too far apart to effectively distribute weight. This can lead to stress fractures, sagging, and eventual failure. Homes built more than 50 years ago may also use outdated materials like wooden shims, which compress over time and cause uneven flooring. At Acculevel, we use steel shims and reinforced support systems to ensure lasting stability.

Technology, Materials, and Modern Renovations
Older homes, especially those built before the 1970s, often relied on untreated lumber and outdated construction methods, leaving them more vulnerable to water damage, rot, and insect infestations. Without modern pressure-treated wood or protective barriers, these structures are prone to deterioration over time.
In addition, modern renovations—such as installing granite countertops, stone tiles, or adding heavy fixtures like pool tables—can overload older floor joist systems that were not designed to support such weight. This strain can lead to sagging floors, cracked beams, and subfloor damage. In these cases, floor joist repair near you or subfloor reinforcement may be required to maintain stability and structural integrity.
