Subsidence Repair in Norwich
Subsidence occurs when the ground beneath a building sinks, causing the foundations to become unstable. This can lead to cracking in walls, sticking doors and windows, and in severe cases, structural failure. Our team of specialists use the latest technology to diagnose the cause of subsidence and implement effective, long-lasting repairs.
Subsidence Repair for Norwich Properties
As Norfolk's county city, Norwich sits on Norwich Crag and chalky boulder clay, making properties across the city susceptible to subsidence, especially during dry periods.
Norwich Crag formation with overlying glacial deposits creates varied ground conditions across the city. The clay-rich soils are highly susceptible to seasonal shrink-swell movement. Our subsidence repair service is specifically tailored to address these local ground conditions, ensuring effective and lasting results for Norwich homeowners.
Signs You May Need Subsidence Repair in Norwich
If you notice any of the following at your Norwich property, it may be time to consider professional subsidence repair:
Diagonal or Stepped Cracks
Cracks wider than 3mm running diagonally from door or window corners, often widening at the top — a classic indicator of ground movement beneath the foundations.
Doors & Windows Jamming
Frames shifting out of square cause doors to stick, windows to jam, or locks to misalign — even in dry weather when swelling isn't a factor.
Wallpaper Creasing or Pulling Away
Wallpaper wrinkling, tearing at seams, or pulling from the wall without any sign of damp suggests the wall behind is moving.
Sloping or Bouncy Floors
Noticeable dips, slopes, or a springy feel underfoot can point to foundation settlement or voiding beneath floor slabs.
Cracks Where Extensions Meet
Separation cracks at the junction between the original building and an extension often indicate differential settlement between the two structures.
Gaps Around Skirting or Coving
Skirting boards pulling away from the floor or coving separating from the ceiling can reveal subtle but ongoing structural movement.
External Brickwork Cracks
Stepped cracks following the mortar joints on outside walls, particularly near corners or below windows, are a strong sign of subsidence.
Sinking or Cracked Paths & Driveways
Paving slabs, concrete paths, or driveways dropping, cracking, or pulling away from the property suggest ground movement close to the foundations.

Subsidence Repair FAQs for Norwich
What are the early warning signs of subsidence in a property?
The most common indicators include diagonal cracks in walls — particularly around doors and windows — that are wider than 3mm and continue to grow over time. Other signs include doors and windows that stick or jam, rippling or creasing wallpaper (not caused by damp), and gaps appearing between walls and ceilings or skirting boards. Seasonal changes in crack width can also indicate clay-related subsidence.
Will my home insurance cover the cost of subsidence repair?
Most standard home insurance policies include cover for subsidence damage, though there is usually an excess of around £1,000. We work directly with all major insurers and loss adjusters, and can manage the claims process on your behalf — including providing the structural reports and documentation your insurer will require.
How long does a typical subsidence repair project take?
The timeline depends on the repair method chosen. Modern resin injection can stabilise a property in as little as one day, while traditional underpinning may take several weeks depending on the extent of the work. During your free survey, we'll provide a clear project timeline so you know exactly what to expect.
Will I need to move out of my home during subsidence repairs?
In the vast majority of cases, no. Modern ground engineering techniques like resin injection are minimally invasive and generate very little noise or disruption, so you can remain in your home throughout. Traditional underpinning may involve some excavation work, but even then, most homeowners are able to stay in the property.
