What happens during underpinning at your home

What determines the scale of foundation work
Every home sits on different ground and has moved for its own reasons. The specialist firm decides what the foundations need after looking at the building and the soil beneath it.
- Depth of stable ground
- The specialist must dig or drill until they reach soil that does not move with the seasons. Deeper stable layers mean more material and longer work.
- Length of affected wall
- A crack near one corner requires less intervention than movement running along an entire side of the house. The extent of damage sets the scope.
- Access around the house
- Narrow side returns or shared boundaries in terraced streets limit what machinery can reach. Restricted access changes how the specialist plans the work.
- Cause of the movement
- A leaking drain demands plumbing repairs alongside structural work. Tree roots require management before any concrete is poured or resin is injected.
The specialist explains exactly what the job involves and what it costs before any agreement is made.
Questions people ask before getting in touch
Worry about cracks usually starts with small signs. These are the things homeowners in Cardiff tend to ask about before deciding whether to report a problem.
The specialist answers these questions directly once they understand what is happening to your home.
- Is my crack serious enough?
- Hairline cracks often follow seasonal temperature changes. Wider gaps, especially diagonal ones near windows, suggest the ground below is shifting. Monitoring tracks the difference over time.
- Will insurance cover the work?
- Buildings insurance often responds to subsidence claims, but policies vary. The insurer usually appoints a loss adjuster who reviews the evidence the specialist gathers.
- Does the whole house need work?
- Rarely. Foundation repair targets the specific walls that have moved. The specialist surveys the structure to confirm where support is actually required.
- How long does it take?
- A subsidence survey happens quickly. Physical repairs depend on the method chosen, from resin injection that cures in hours to mass concrete that sets over days.
