If cracks appear while tunnelling or excavation is taking place nearby, treat the situation as a potential safety and evidence problem—not proof that the project caused the damage. Leave any area that may be unstable, report the concern promptly to the project operator, document changes, notify your insurer if your policy requires it, and obtain qualified advice before authorising repairs.
1. Make the house and site safe first
Do not enter an unsafe excavation, stand beneath an unstable wall, or remain in a part of the building that appears to be moving. Leave the affected area and contact emergency services or the relevant local authority if there is an immediate danger.

Warning signs that justify urgent action include rapidly widening or lengthening cracks, walls that are bulging or leaning, doors or windows that suddenly jam, floors that slope or feel unstable, falling masonry, unusual movement or noise, and damage close to a foundation or retaining wall. A crack alone does not tell you whether a building is unsafe, so use caution when the pattern is changing or other signs are present.
The UK Health and Safety Executive (HSE) identifies undermining nearby buildings or walls as an excavation risk. Its guidance says excavations should not undermine foundations and that foundation surveys or structural-engineer advice may be needed. The guidance is aimed mainly at people planning and carrying out excavation; a homeowner should report concerns to the operator rather than inspecting or entering the worksite.

2. Create a dated record before conditions change
Document the condition as soon as it is safe to do so. Use the same viewpoints each time, include a ruler or another fixed scale where practical, and keep the original files rather than relying only on compressed messaging-app copies. Your record should state:
- the date and time you first noticed each crack;
- the room, wall, ceiling, floor or external elevation where it appears;
- the approximate length, width and direction of the crack;
- whether paint, plaster, tiles, brickwork or finishes are also displaced;
- any change you observe, including changes after rain, vibration or further excavation; and
- the dates and contents of calls, emails, visits and inspections.
Keep project letters, notices, emails, baseline-survey documents, inspection reports, estimates and receipts together. Do not remove damaged finishes or fill cracks before they have been photographed and, where appropriate, inspected. If emergency work is necessary to make the property safe, record the condition first when possible and keep invoices and the contractor’s written description of the work.
3. Report the damage through the project’s own route
Use the named helpdesk, community-relations contact or property-damage channel supplied for the actual works. Give a factual description: where the crack is, when it was noticed, what construction activity is nearby, and whether it is worsening. Ask the operator to confirm:
- the formal reporting procedure and the person handling the case;
- what evidence and forms are required;
- whether a pre-works condition or defect survey exists for your property;
- whether monitoring data is available or will be collected; and
- any notice, inspection or claim deadlines that apply.
Report promptly even if you are uncertain about the cause. Prompt notice preserves an opportunity for the operator to inspect while the excavation and ground conditions are identifiable. Do not assume that a project in another town, region or country uses the same scheme or deadlines.
HS2 illustrates why project rules must be checked
HS2 tells residents who believe construction has damaged their property to contact its helpdesk with a description of the damage or nuisance. Its resident information also says people who are worried about tunnelling damage and have not heard from the project should contact the helpdesk. HS2’s arrangements are an example for that project, not a universal compensation process.

For HS2, the High Speed Rail (London to West Midlands) Act 2017 gives the organisation legal responsibility to repair physical damage caused by its construction or operation. An Old Oak Common process describes a small-claims route for claims under £10,000 and a separate damage-claim process for claims over £10,000. Those thresholds and procedures must be confirmed with HS2 before relying on them. The project’s Works Information Paper C3 also describes written and photographic defect surveys and later comparisons, with particular notice and timing conditions. Do not transfer those conditions to a different tunnel or excavation.
4. Notify your insurer without assuming cover
Check your buildings and contents policies for notification requirements and follow the insurer’s instructions before arranging non-emergency repairs. Cover depends on the policy wording, the identified cause and the law where the property is located. A policy may distinguish between accidental damage, subsidence, settlement, groundwater, defective construction and damage caused by a third party.
Tell the insurer that nearby tunnelling or excavation is taking place, describe the observed damage and explain what the project operator has said, if anything. Ask whether the insurer wants to appoint an adjuster, surveyor or engineer, and whether authorisation is required before opening up walls, removing finishes or commissioning substantial works. Keep the claim reference and all correspondence.
If the insurer delays, communicates poorly, disputes the timing or type of ground movement, or proposes inadequate repairs, make a formal complaint through its complaints process. The Financial Ombudsman Service says a consumer can normally bring the matter to it if the insurer has not issued a final response within eight weeks or the consumer remains unhappy with that response. Eligibility, time limits and jurisdiction should be checked for your circumstances.
5. Do not confuse timing with proof of cause
A crack that appears during nearby works may be related to those works, but the coincidence does not establish causation. Buildings crack for many reasons, including seasonal moisture changes, defects that pre-date the project, leaking drains, tree-related movement, local ground conditions, settlement and mining-related subsidence. The relevant question is what ground or structural movement occurred, when it occurred, and whether the project’s activities could have produced it at your property.

The Financial Ombudsman Service notes that ground-movement disputes can require expert evidence and technical data. A thorough investigation may examine foundation depth, nearby drains and other services, borehole samples and crack monitoring. Monitoring can show whether the building is still moving, how much movement occurs and whether it follows a seasonal pattern. In some cases, monitoring may span a year so that all seasons are represented; that is an example of practice, not a fixed requirement for every claim.
Evidence that can help establish a connection
| Evidence | What it can show | Important limitation |
|---|---|---|
| Pre-works survey or photographs | Whether cracking or defective finishes were recorded before construction | A survey may not detect concealed defects or every hairline crack |
| Dated photographs and measurements | How the visible condition changes over time | Images do not identify the underlying mechanism by themselves |
| Crack monitoring | Whether movement is continuing, its approximate magnitude and possible seasonal pattern | Duration and equipment should be selected by a competent professional |
| Foundation and drainage investigation | Depth, support conditions, leaks or other potential causes | Opening up or drilling requires appropriate planning and permission |
| Construction and monitoring records | Timing of excavation, ground treatment, vibration or settlement near the property | Access depends on the operator’s scheme and applicable law |
6. Choose the right professional assessment
Obtain independent advice when damage is significant, progressing, close to foundations, or disputed by the operator or insurer. A structural engineer can assess structural safety and specify monitoring or remedial design. A chartered building surveyor can document the building condition, investigate defects and prepare evidence. Depending on the site, a geotechnical engineer, drainage specialist or other expert may also be needed.
When comparing professionals, ask about:
- experience with structural movement, excavation or ground-movement claims;
- independence from the tunnelling operator and from contractors who might later perform the repair;
- the inspection, measurements, testing and records included in the fee;
- whether you will receive a signed written report with photographs and conclusions;
- the proposed scope, assumptions, exclusions and total fee; and
- who will interpret monitoring results and design any repair.
The HSE’s advice supports surveys and engineer input where excavation may affect nearby foundations. Technical evidence is also important when an insurer or project operator disputes responsibility. A general builder’s visual opinion may be useful for a minor finish defect, but it is not a substitute for structural or ground-movement assessment where the cause or safety is uncertain.

Filling, replastering or repainting may hide evidence while movement continues. Conversely, delaying an emergency stabilisation measure is unsafe. Follow the engineer’s or authority’s advice on temporary protection, monitoring and the timing of permanent work.
Do not assume that underpinning is the answer. Underpinning changes the support beneath a building and must be designed and sequenced for the particular ground, foundation and load conditions. The method may involve staged excavation, reinforced concrete, piles or another engineered system; the correct option cannot be selected from the appearance of a crack alone.

Welsh Government building-regulations guidance says approval will normally be required for underpinning in Wales and that a structural design should cover the construction process. Excavation must follow the engineer’s instructions. Poorly carried out underpinning can damage or collapse a home, so design and construction should be handled by experienced people. Requirements differ elsewhere in the UK and in other jurisdictions; ask the local building-control authority what approvals, notices and inspections apply.
8. Keep the claim organised
Use one folder—digital, paper or both—with a chronological index. Separate facts you observed from opinions supplied by professionals. Record every inspection date, the name and role of the person attending, photographs taken, measurements, recommended next steps and any deadline stated by the operator or insurer.
Ask for important decisions in writing. If a project representative says the damage is pre-existing, request the survey or technical basis for that view. If an insurer proposes a repair, ask what defect it is intended to address and how future movement will be handled. Avoid signing a full and final settlement or releasing claims until you understand what damage, costs and future monitoring it covers and have taken advice where necessary.

9. A separate route for suspected coal-mining subsidence
In Great Britain, suspected coal-mining subsidence follows a specific route and should not be confused with a claim against a tunnelling project. GOV.UK says a chartered surveyor can help establish whether damage is due to coal mining before a claim is submitted to the Mining Remediation Authority. Use that route only when coal mining is a plausible cause; nearby civil-engineering excavation requires the project’s own process and the ordinary insurance and technical-evidence steps.
Practical decision checklist
| Situation | Priority action |
|---|---|
| Immediate instability, falling material or rapidly changing movement | Leave the area, keep others away and contact emergency services or the local authority. |
| New but apparently stable cracking | Photograph and measure it, start a dated log and notify the project operator. |
| Insurer may be involved | Check the policy, notify the insurer and follow its instructions before non-emergency repairs. |
| Cracks are worsening, extensive or disputed | Arrange an independent structural or building-survey assessment and ask about monitoring. |
| Someone recommends underpinning immediately | Pause major work until an appropriately qualified professional provides a design, sequence and approval plan. |
Questions to put to the operator, insurer and engineer
- Was my property inspected or photographed before the works began?
- What excavation stages, ground-treatment operations or monitoring points are closest to the building?
- What is the formal deadline for reporting damage and submitting supporting evidence?
- Who will pay for investigations if responsibility is disputed?
- What monitoring interval and duration will distinguish continuing movement from seasonal change?
- Which repairs are temporary, and what evidence supports the proposed permanent solution?
- What building-control approvals, notices and inspections are required before structural work starts?
Bottom line
Protect people first, document the condition, report it through the actual project’s published process and notify your insurer according to the policy. Establishing responsibility may require surveys, technical records and monitoring rather than a visual guess. Have significant or disputed damage assessed independently, and never authorise underpinning or other foundation work without a site-specific professional design and the approvals required where the property is located.
