How to tell if your house is suffering from foundational problems at foundation level

As your home sinks deeper into the ground upon which it’s built, structural challenges will reveal themselves visibly, both inside and outside the house. The sinking causes an immense amount of force to be exerted on the house itself, straining your home’s floor, walls, ceiling and even the roof.

Sinking is often an indicator of a home suffering from subsidence. If the sinking isn’t stopped, these house foundation problems may multiply, which means the cost of repairs will escalate to hurt your wallet. Working out whether or not you’re living in a sinking house isn’t too hard. Read on for the sure-fire indicators below.

Wall Cracks

Sometimes wall cracks are purely cosmetic. Other times, the cracks indicate structural issues brought on by your house sinking. If your wall cracks appear stepped, appear in both the internal and external walls of your house as well as the corners of walls, your house may be sinking.

Ceiling and Cornice Cracks

Just like wall cracks, ceiling cracks can be superficial but can also indicate deeper structural problems due to the sinking of your home. The sinking places pressure upon the entire house starting in the foundations. This travels up walls into your cornices and ceiling, causing them to crack.

door-jam

Doors and Windows Jamming

If you can’t close or open your doors and windows without them jamming, there’s a likelihood the foundation of your home has sunk, unevenly. What was initially level isn’t anymore. It’s this lack of balance in the structure’s foundation that causes doors to hit the floor when you open them or has walls squeezing windows in so they can’t move.

Leaning or Off-Level Walls

The source of leaning or off-level walls is the same as jammed windows and doors. As your house sinks, the unevenness of your home’s foundations can cause walls to lean one way or another. Leaning or off-level walls are horribly dangerous if left unchecked and unfixed. They have the potential to fall over and cause injury or even death.

Sloping Floors

If you have sloping floors, the reason is again, unevenness in the foundations of your home due to sinking. Your floors will slope as one side of the house sinks downwards more than the other. To double check for a sloping floor, just place a ball on the floor and see if it rolls away from you. If it does, it’s likely you’re in a sinking house.

gap-gap

Gaps Between Walls, Floors and Bouncing Floors

As the foundation underneath your home sinks, the floors pull away from the base of your interior walls causing gaps to appear. The sinking of your home may also result in a floor that becomes bouncy as you walk upon it. This is likely caused by the ground pulling away from the upper parts of your home’s structure. This is dangerous because this indicates your floor’s support system is beginning to sag and weaken.
