Does home insurance cover foundation movement or sagging floors? Foundation damage caused by shifting or settling earth or sagging floors caused by rotting floor joists are typically not covered by homeowners insurance. If the damage is caused by flooding or an earthquake, you'll typically require separate coverage.
And when the soil under your foundation shifts or erodes, that slab will sink and cause sagging floors. In most cases, concrete lifting is the best and most reliable repair method. At Acculevel, we believe slab jacking is the best type of concrete lifting.
You can remove that risk by raising your living room up to floor level. The cost to rasie a sunken living room ranges from $5,000 to $25,000 or more depending on the size of the room and how you go about the remodel.

Sagging floors usually indicate subflooring and floor joist issues. These repairs are significant and require the expertise of a carpenter—not a handyperson. Before laying down finished floors, hire a local carpenter specializing in unfinished work to help you with this major home improvement project.
Sagging floors are a sign of serious damage to the joists beneath your home and the structure of your home overall. Left untended, this can lead to injury, property loss, and disaster. Worse, insurance companies often will not pay for such losses or repairs if you ignored the issue once the early signs became visible.
Average Cost to Level the Floor in a House
On average, you are looking at about $3 – $5 per square foot.
Subfloor Damage
If your foundation has settled since the house was built, your subfloor may have also settled, creating a dip between the boards on top and the subfloor boards beneath. This can cause low spots to form, which can also be perceived as soft spots. You'll need a professional to repair the plywood floors.
It's common for older houses to have some degree of unevenness in their floors. Over time, various factors like settling, wear and tear, and environmental conditions can cause floors to shift slightly.
Dwelling coverage, on your condo or homeowners policy, may pay to repair or replace your floors and carpet if they're damaged by a covered peril. For instance, if your home's floors are damaged in a fire, your home insurance may pay for new flooring, up to your policy's limits and minus your deductible.
Licensed home inspectors primarily look at the four pillars which are the foundation, floor, walls and roof. Cracking, sagging, shifting or missing features on any of the pillars may be considered structural damage if the ruin is severe.
However, the uneven floor may be an indicator of a larger, unseen problem with the house. If your potential new home has buckling floors, you should immediately consult a home inspector to investigate the root of the problem.
House Lifting Cost
House lifting costs $10,000 to $40,000 just to elevate the structure. The average cost to raise a house above the flood zone is $20,000 to $80,000 for piers or pilings. The average cost to lift a house and replace the foundation is $20,000 to $100,000, or up to $150,000 to put in a basement.
Humidity and moisture can cause severe problems for floor joists. When exposed to damp conditions, wood can rot and become weak. This can lead to sagging floors and even floor collapse. Also, damp environments attract pests like termites and carpenter ants that can damage floor joists.
The typical costs for repairing sagging floors start at $1000 and can go up to $10,000, with the average rate being around $300 per square foot. But this can vary depending on the extent of the damage and materials needed to get the job done.
By dividing the span of the joist in inches by 360, you can calculate the maximum acceptable deflection. For example, if a joist spans 10 feet, dividing 120 by 360 results in approximately 5/16″ of allowable sag in 10 feet.
Structural Weakness: When floors sag, it often means that the beams and joists supporting them are weakened or damaged. This can lead to further deterioration and issues such as cold air leaks, pests, wall separation, and collapsing floors.
Safety factor is a measurement with which your floor was designed to support loads without collapsing. Most homes have a safety factor of 40 PSF (pounds per square foot).
How long does sagging floor repair take? The project duration depends on the severity of the damage and the type and quantity of necessary repairs. Ohio Basement Authority's team aims to work efficiently to minimize disruption. Most repairs can be completed quickly, often in a day or two.
A good rule of thumb to estimate is that a self leveling concrete floor will cost around $600-850 per 100 square feet.
The cost of foundation repair typically ranges from $2,000–$7,500, with a national average of $4,500. The cost depends on several different factors like home size, accessibility to the foundation, and soil stability.
