Subsidence damage insurance claims

Subsidence is the downward movement of the ground beneath a property, which causes the foundations to shift and can result in cracking, structural movement, and in severe cases, significant structural damage. It is different from settlement, which is the normal, minor movement that occurs in most buildings over time. Signs of subsidence include diagonal cracks at corners of windows and doors, cracks that are wider at the top than the bottom, doors and windows sticking, and visible sloping or displacement in floors or walls. If you suspect subsidence, it is important to seek professional assessment promptly rather than waiting to see if the situation develops.

Subsidence is covered under most standard Irish home insurance policies, but it is subject to a higher excess than other claim types, typically 1,000 euro or more, and insurers apply significant scrutiny to subsidence claims. Cover generally includes the cost of structural investigation, underpinning or alternative foundation repair, and reinstatement of internal and external damage caused by the movement. Whether your claim is accepted, and the level of settlement offered, depends on identifying the cause of the movement, the extent of the damage, and how well the claim is documented and presented.

The most common causes of subsidence in Ireland are shrinkable clay soils, which expand and contract with moisture levels; tree root intrusion, where roots draw moisture from the soil and cause it to shrink; leaking drains or pipes, which can wash away sub-surface material; inadequate foundations in older properties; and in some areas, historical mining or landfill. Identifying the specific cause is critical to both the repair solution and the insurance claim. Insurers need to understand the cause before they will agree to fund remediation.

Not all cracks indicate subsidence. Hairline cracks in plaster are common and usually the result of normal thermal movement or drying shrinkage. Cracks that suggest subsidence are typically diagonal rather than vertical or horizontal, wider at one end than the other, appear at structural junctions such as corners of windows and door frames, and progress over time. If you have cracks that are widening, recurring after repair, or accompanied by sticking doors or sloping floors, you should have the property professionally assessed. A loss assessor can help coordinate the right specialist surveys.

Subsidence is downward ground movement beneath a property. Settlement is the gradual, minor compaction that occurs in most buildings and is generally not covered by insurance. Heave is the upward movement of ground, typically caused by clay soils absorbing water after a tree root source is removed, and is treated differently to subsidence in most policies. Understanding which type of movement is occurring matters for both the repair approach and the insurance claim. An independent structural engineer’s report is usually required to establish this definitively.

Document any cracks or movement with dated photographs. Try to note when the cracking first appeared and whether it has changed over time. Do not carry out repairs to cracked areas before having the property assessed, as this removes the evidence your insurer needs. Contact your insurer to notify them of the potential claim. Before your insurer’s loss adjuster visits, consider speaking to a loss assessor. This ensures you have independent advice before any assessments or recommendations are made on your behalf.

The cost of subsidence repair varies enormously depending on the cause, the extent of the movement, and the repair method required. Underpinning a single section of foundation can cost from 10,000 to 30,000 euro or more; whole-house underpinning can run to six figures. Alternative methods such as resin injection or helical piers may cost less in suitable cases. Where drainage is the cause, pipe repair may resolve the issue without major structural intervention. Your insurance policy should fund the repair up to your sum insured, less the applicable excess. Having an independent assessment of the repair scope ensures you are not accepting an insurer-appointed solution that undervalues the work needed.

A subsidence claim can affect your future insurance premiums and in some cases your ability to obtain cover on standard terms. Insurers view subsidence as an ongoing risk once it has occurred. However, the impact depends on whether the cause has been fully remediated, whether a structural engineer has confirmed the property is stable, and what documentation exists to support this. It is worth understanding the long-term implications before lodging a claim, particularly for lower-value cases where the damage may be within or close to the excess level.

Subsidence claims often take longer than most other home insurance claims because the insurer usually needs to investigate the cause and monitor movement before repairs can be agreed. In many cases, the process takes 12 to 24 months, while more complex or disputed claims can continue for several years.

Our fee for subsidence claims is typically 10% plus VAT of the final settlement, agreed in advance. Given the complexity of subsidence claims, the length of the process, and the significant sums involved, professional representation is particularly important. Subsidence claims require coordination of multiple specialists, careful management of the insurer’s investigation process, and rigorous scrutiny of repair scopes and settlement offers. The difference between a well-managed and a poorly managed subsidence claim can be substantial. Your first consultation with OMC Claims is free.
