Basically, underpinning restores the strength of the foundation of your home. You should consider getting your basement underpinned if you see the following signs:
Check the interior and exterior walls for cracks and fissures regularly. Sometimes, the walls even start crumbling if not paid proper attention to. If this starts to happen, call for underpinning services immediately.
Poor fitting doors and windows
Damages to the foundation cause doors and windows to not fit into their frames. This means that they can lash open at any time. It happens when the alignment between the frames and the doors becomes disjointed, and that can point towards some problems in the foundation of the property.
Improper drainage can be the cause and effect of foundation damage. If moisture from the basement is seeping into the walls of the house, then it is a telltale sign that the foundation of the building is giving away.
The property is lopsided
When the foundation is damaged, the soil bed around it can sink at places, causing the whole structure to lean on one side. This is a sign of serious foundation damage, and should be brought to the attention of professionals immediately. Shifts in foundation are signified by curves on blocks of the foundation, or in the concrete of the walls.
It is not necessary that problems occurring in the basement should stay there. Sometimes, they manifest themselves in the upper layers of the house, especially the ceilings. So if you find that the floors of your house are slanting, or the ceiling has some indentations, call for underpinning services immediately.
The original foundation is too old
If the foundation of the building is too old, then it may shift on its own, because of the changes in the soil around it. It can also become unstable due to years of decay. So, if you feel that the foundation needs repair, you should consult a professional as soon as possible.
