Underpinning
Underpinning involves strengthening the existing foundations of a building to provide additional support. This is typically required when the original foundation is no longer strong enough to support the structure, often due to changes in soil conditions, nearby construction, or subsidence damage.
Signs You Need Underpinning
Cracks Near Foundations
Cracks visible at or near ground level on external walls, suggesting foundation movement.
Bulging or Leaning Walls
Walls that are no longer plumb, indicating the foundations have shifted.
Gaps Around Window Frames
Gaps opening between window frames and brickwork caused by foundation settlement.
Cracks in Floor Slabs
Internal floor slabs cracking as the foundation beneath them moves unevenly.
Why Act Early
Avoid Structural Failure
Weak foundations worsen over time. Early underpinning prevents partial or complete structural failure.
Simpler, Cheaper Repairs
The earlier you underpin, the less extensive the work needs to be — saving time and money.

Frequently Asked Questions
What types of underpinning do you offer?
We offer several methods including mass concrete underpinning, mini-piled underpinning, beam and base systems, and resin injection. The best method depends on your property's specific foundation type, soil conditions, and the extent of movement.
How much does underpinning cost?
It varies. Costs depend on the property size, depth of existing foundations, chosen method, and ground conditions. We provide free, no-obligation quotes after an initial survey so you know exactly what to expect.
Is underpinning disruptive to my home?
It can be, depending on the method. Traditional mass concrete underpinning involves excavation and can be disruptive. However, modern alternatives like resin injection are far less invasive and can often be completed in a day.
Do I need planning permission for underpinning?
No, generally not. However, building control approval may be required depending on the scope of work. We handle all necessary approvals and certification as part of our service.
