What is the difference between underpinning and foundation?

Underpinning is used to reinforce or repair existing foundations in the case of subsidence. Foundations are the original lower structures used to distribute the weight of a building.

Can you live in a house that needs underpinning?

It will depend on the extent of the work needed if you will be able to live in the house during the underpinning process. However, if the property needs underpinning but this process has not begun it is not safe to live in a property with subsidence and these properties will likely be ‘unmortgageable’.

Do cracks always mean subsidence?

Not all cracks in walls mean subsidence. Smaller, superficial cracks can often be fixed with painting and redecorating. However, larger cracks can point towards issues with the foundations of the house and should be investigated by professionals.
