Cavity wall leakage covered by insurance explained
Cavity wall leakage covered by insurance means that your buildings insurance or the HOA building insurance covers consequential damage to the structure and finish when water penetrates walls or connections via the cavity. The core issue lies in sudden and unforeseen water causing damage to masonry, insulation, window frames, and interior finishes. The cause itself may be covered under certain conditions, but insurers primarily cover the consequential damage. Contents insurance covers damage to movable items. Think of wet carpeting, furniture, and appliances. We help you demonstrate the distinction between cause and effect and link this to the policy conditions so that coverage for cavity wall leakage by insurance becomes the maximum achievable. Ultrices Leak Detection works nationwide with insurers and HOA managers and provides an expert report that meets the requirements of the Dutch Association of Insurers (Verbond van Verzekeraars) and Kifid.
Coverage via buildings and contents insurance in practice
Insurers apply a few fixed anchors. Sudden precipitation damage and water penetrating the wall through a defect in the mortar joints, window frame connections, or lead flashing are often covered if unforeseen circumstances are involved. Deferred maintenance and gradual wear and tear are usually excluded, but consequential damage inside the building is. You often pay an excess. Salvage costs to prevent further damage are usually reimbursed. For a Homeowners' Association (VvE), the cavity wall falls under the collective policy. We link the leak detection report to the policy articles and substantiate causality according to the NEN 2778 methodology for assessing moisture in buildings, and where relevant, conduct a water test in accordance with practical guidelines derived from NEN EN 1027 for connections at facade openings. In this way, we make cavity wall leakage reimbursed by insurance concrete and verifiable.
Causes of cavity wall leakage and what insurers often acknowledge
- Facade penetration and broken joints: due to cracked mortar joints and porous brick, rainwater penetrates the outer shell and reaches the inner wall via the cavity, resulting in mold and loose plaster layers
- Faulty or contaminated cavity: cement protrusions, debris, or contamination cause cavity bridges, through which moisture is drawn in by capillary action, especially during wind pressure and driving rain
- Problems with cavity wall insulation: wet glass wool, clumped EPS beads, or porous PUR cause thermal bridges and moisture penetration with thermal imaging patterns that we make visible
- Leaking connections: Failing lead flashing, water barrier, or sealant at window frames and expansion joints allows water to run into the cavity, causing moisture penetration under wind load

Our leak detection for insurance coverage, step by step
- Intake and policy checkWe analyze your situation, the building or HOA policy conditions, and determine the correct burden of proof for cavity wall leakage covered by insurance.
- Non-destructive testing: thermography with FLIR camera, endoscopy in the cavity, moisture measurements with Tramex and dye tests, and where necessary smoke test or tracer gas on connections
- Separating source and effectWe record measurement data, photos, thermal images, and building physics analysis, and link cause to consequential damage according to NEN 2778.
- Waterproof and validation: targeted water loading on details such as window frame connections under controlled conditions with logging of temperature and wind to demonstrate repeatability
- Expert report: within three days you will receive an insurance-worthy report with cause-and-effect photos, repair advice, and a cost estimate including salvage costs

Documents and evidence your insurer wants to see
- Insurable leak detection report: clear regarding cause, location of measurement method and substantiation of sudden and unforeseen nature, with reference to relevant normative frameworks
- Photo file and thermography: overview of facade details, interior spaces, cavity images and thermal patterns to confirm the water route

Examples of cavity wall leakage covered by insurance
- Driving rain through window frame connection: leakage under windowsill due to failing sealant and waterproofing; consequential damage to plaster and floor finish reimbursed via building insurance
- Cavity bridge with insulation after blowing: damp interior wall and mold in bedroom; consequential damage reimbursed; cause partially excluded, but restoration of interior finish and emergency drying.
- Cracked expansion joint: water ingress due to wind pressure with visible streaks on thermography; repair of jointing and interior damage reimbursed with deductible
- Leaking rainwater drain in cavity wall: tap water leakage leads to wet cavity insulation; both cause and effect covered under the tap water section

Frequently asked questions
Is cavity wall leakage covered by my buildings insurance, and what constitutes consequential damage?
Usually, buildings insurance covers consequential damage from a sudden cavity wall leak, such as damp patches, mold, peeling plaster, and the repair of affected walls or floors. Repairing the cause may be different. The insurer may exclude coverage in the case of overdue maintenance or a structural defect, whereas damage caused by unexpected rain or a burst pipe is often covered by the policy. Contents are covered by your contents insurance.
We link the cause, location, and consequential damage in a clear leak detection report in accordance with the guidelines of the Dutch Association of Insurers. This increases your chances of a quick payout. See what an insurable report looks like via this example of a leak detection report for cavity walls.
Does my insurer reimburse the leak detection costs and the expert report for a cavity wall leak?
Many Dutch insurers reimburse reasonable investigation costs when covered consequential damage occurs and the investigation is necessary to determine the cause. An independent and substantiated expert report is crucial in this regard. Within three days, we deliver a complete dossier including photographic evidence, measurements, thermography, endoscopy or spray testing, and a repair recommendation used by claims experts.

Is damage caused by damp cavity wall insulation or poor pointing covered by insurance, or does it apply as an inherent defect?
Damage caused by an inherent defect, such as outdated cavity wall insulation or overdue pointing, may be excluded by the insurer from coverage for causative repair. Consequential damage, such as damp interior walls, mold, or damaged plasterwork, is often reimbursed, provided the event is sudden and unforeseen. In the event of rainwater penetration through open weep holes, a damaged damp-proof course, or a leaking lead flashing, coverage may depend on the state of maintenance.
We substantiate the exact leakage route with camera inspection, smoke test, or targeted spray test, and document maintenance condition and thermal bridges. This provides the claims expert with a basis to determine coverage under building or property insurance. This is what such an investigation looks like in practice via camera inspection of the cavity wall.
What steps should you take immediately in the event of a cavity wall leak for the maximum chance of reimbursement?
Limit damage and take photos of moisture traces, drip points, and the weather pattern during rain. Report the damage promptly to your insurer or to the HOA manager if it concerns an apartment complex. Next, engage a recognized leak detection company for a non-destructive inspection and keep quotes, invoices, and communications. Also note when the leak became visible.
We are available twenty-four hours a day, seven days a week, are on location within an hour, work without demolition or breaking, and deliver a complete insurance file with a success rate of over ninety-nine percent at the cause location.
