Older homes, or even many newer homes on poorly compacted soil, could result in sloping floors on the second floor. Sagging floors on the second story can also have a domino effect that causes further issues throughout your home. These types of home issues can also significantly decrease the value of your home when it comes time to sell. You might not even notice that it’s happening. 

Here is what to look for when identifying sagging second floors.

Signs of sagging second floor: 

Sticking windows and doors

Your doors and windows might have fit before, but they could have changed over time. If your doors and windows are either fitting too tight, or too loose, it could be a sign that your floors aren’t level. 

Cracks in your drywall and corners 

Cracks could be showing up on your home’s walls, specifically in the corners or near window or door frames. This could mean that your floors and structure of the home is shifting. 


If you have noticed gaps between the floor and the wall, this is a good indicator that your floor has sunken, sagged, or sloped significantly. 

Bouncy or squeaky floors

If your floors feel springy, or make squeaking noises as people walk across them, this is a sign that your floors are sagging or sloping.

What causes a sagging floor on second story?

Sagging floors could indicate a few different issues including damaged wood under your flooring, a deteriorating support structure, or interferences such as pests or water leaks. However, a sagging floor could also indicate issues with your home’s foundation. 

Improperly compacted fill soil 

If the soil beneath your home wasn’t properly filled and compacted, it can result in issues with your foundation as it provides inadequate support for your home. 

Excess moisture 

Water damage can certainly cause sagging floors. If your home is exposed to excess moisture, it can affect your foundation. Water damage can be caused by several factors including pooling water, clogged gutters, and soil erosion.  

Soil movement 

Soil movement, especially in the Vancouver Island & Greater Vancouver area, is a very common occurrence. Soil naturally expands as it becomes wet, and shrinks when it becomes dry. These changes in climate and time passing can cause the soil to move, and therefore, your home’s foundation. 

Clay soils are also common in the Vancouver area but they can also cause foundation problems. Clay acts like a sponge and can expand and shrink beneath your home with seasonal changes. As the soil expands, it puts pressure on the foundation and as it contracts, it lacks support for the foundation. The constant changes in season and weather eventually leads to foundation issues and sagging floors. 

Structural issues

Foundation issues are a common cause of sloping and sagging floors. Foundation damage can be the result of a laundry list of possibilities including poor structural design, the soil beneath your home, and settlement over time.
