Why Do I Get Floor and Wall Gaps?

Sagging floor joists and house settling are two of the problems that can cause floor wall gaps. Sagging floor joists occur when the support pillars that hold up the floor joists are spaced too far apart.


The uneven spacing overloads the floor joists which causes them to bend and sag. If sagging floor joists is the problem, then your floor can be uneven, squeak, or have a gap between the wall and floor.

House settling is caused when the ground your home is built on changes or shifts. Soil changes happen when there is too much water, the soil's too dry, or the soil isn't prepared properly before the build. Think of the soil your home sits on like a sponge:

It Expands When Wet
Moisture problems and wet conditions can create a problem. When wet, the sponge expands and becomes soft. The same happens to the soil. The wet soil pushes against your foundation, forcing the walls in, creating foundation problems.

It Shrinks When Dry
When dry, the sponge contracts. During the hot summer or a drought the soil your home sits on will dry out. As water evaporates, it starts to shrink, pulling away from your foundation. The newly created space next to your foundation allows for foundation movement and house settling.

How Do I Fix Floor and Wall Gaps?

Sagging Joist Floor Support

This is not a do-it-yourself project. Don’t be fooled into thinking that placing metal beams or concrete blocks under the sagging floor joist will fix the problem. This quick fix will fail: collapsing and creating even more problems.


And if you plan to sister the beams it's important to know that this may not fix the source of the problem. If your home's settling or is built on unstable ground, then underpinning will be the only option that truly fixes the problem.

JES put 8 stabilizers under my poor sinking house. I was very pleased with their whole operation. No hard sell from the foundation inspector. He just told me what needed to be done and the price. It was intense work, under difficult circumstances. Anything I asked of JES, JES did. I can say that my floors are more even and that the creaking in the floors has gone away.
