Hugo:
«When did you last look behind that access panel?»
Why AquaRisk rather than simply calling a plumber?
Your plumber can also inspect and repair. AquaRisk complements that expertise with a consistent recording method, traceable risk classification and an ongoing building history. The assessment is not a repair quotation.
Freedom to choose
You decide on the commission, timing and contractor: your usual plumber, an AquaRisk partner or another trade business. No repair contract arises automatically. Urgent hazards still require prompt action.
A continuous record
Documentation remains linked to the building. Work records and follow-up inspections extend its history even when contractors change.
Unremarkable outside. Look behind the access panel.
Photographs supplied by Holger Holling from his work. Repair details are based on his account. A photograph alone does not prove the cause of a leak or the watertightness of the entire system; repairs are a separate service.
Case studies
Two defects. Two water-damage incidents.
2 × CHF 12'000
A dishwasher supply hose that had been kinked for years burst. In the second incident, a leaking mixer cartridge and limescale blocked the swivel spout; forcing it further broke the connection pipes.

CHF 11'500
Six months after buying the house, water dripped from a ground-floor light fitting. A burst flexible hose inside the concealed toilet cistern was responsible, rather than the initially suspected shower connection.

about 15 litres
The sink waste screw broke as the washing-up water was released. Around 15 litres ran beneath a solid-wood kitchen.

CHF 80'000
A basin tap hose burst while the residents were on holiday. According to the account, the hoses had been fitted twisted and kinked.

Maintenance and cover
Helvetia lists inadequate building maintenance and normal wear as possible exclusions. The cause and applicable terms are decisive. Source →
Regular checks
Zurich recommends professional installation, regular appliance maintenance and checks for watertightness of fittings. Source →
Possible contractual consequences
Mobiliar’s terms describe cancellation rights following a covered loss and contract adjustments. Premiums or deductibles do not automatically increase after every claim. Source →
Your policy, applicable terms and the individual claim are decisive. These sources do not establish insurer recognition, cooperation or a requirement to use AquaRisk-Analyse®. The report is not a coverage commitment. Insurance details in the case studies come from those affected and are not a general coverage rule.
The documentation stays with the building.
Like a service logbook: the initial assessment, findings, photographs, decisions, work and follow-up inspections are brought together for the property. An invoice records reported work; a new visual inspection is needed to describe the current visible condition.
Recorded condition
Date, scope, finding, classification and photographs.
Decision
Work commissioned, third party planned or no action at present.
Work record
A dated addition with a service or repair document.
Follow-up
New findings, outstanding items and the next recommended assessment.
Intervals depend on the property and findings. Follow-up assessments are separate commissions, not an automatic subscription. The history covers commissioned assessments and supplied documents, not continuous monitoring. Immutable storage or cryptographic protection is not promised.
A QR code links the physical label to the current inspection status.
A property-specific QR access can be agreed. It links the building’s label to its latest assessment, open findings, documented work, follow-up inspections and next recommended date. The physical label is not a permanent certificate of safety.
Access, scope and permissions are agreed in advance. The owner or authorised manager determines who may see which information. A QR code alone does not grant access. This public website does not display private property or customer data.
How the Risk Engine fits into the AquaRisk methodology.
Standardised recording → assessment of the visible finding → risk classification → recommendation → documented follow-up. The Risk Engine supports structured assessment. It does not replace professional judgement or further investigation. No calculated probability of damage or comprehensive proof of safety is promised.

Frequently asked questions
What is inspected?
In bathrooms, kitchens and guest toilets, the scope may include accessible taps, connections, flexible hoses, cistern feeds, joints, drinking-water and drainage components. Heating areas may include visible manifolds, radiator connections, pipes and pressure-maintenance components. Missing or inaccessible items are recorded separately and are not rated as free of defects.
Who is the assessment for?
Apartment and house owners and property managers. Multiple units receive an individual quotation.
How long does it take?
Duration and access depend on property size and the agreed scope. We clarify the expected time before commissioning.
What does it cost?
Starting prices for the initial assessment within the agreed visual scope: apartment from CHF 249, single-family home from CHF 499. Travel, property size, surcharges and the binding total are agreed before commissioning. Follow-up assessments, repairs and any digital property access are agreed separately; no automatic subscription.
Will I receive a written report?
Yes. You receive an internally reviewed, dated report with a version identifier, photographs linked to findings and practical recommendations. Delivery timing is agreed personally.
What happens if a concern is found?
The finding is linked to its inspection point. Recommendations identify observation, further professional investigation or required action. Repairs and additional investigations are separate commissions.
Are walls opened or systems changed?
Only agreed, accessible and visible areas are inspected. No opening, dismantling or intervention; safety valves are not operated and pressure or settings are not changed. This is not comprehensive maintenance, specialist design, assessment of concealed components, confirmation of SIA compliance or a guarantee against future damage.
Does the assessment replace insurance or maintenance?
No. The report is not a coverage commitment or guarantee against damage and does not replace mandatory or specialist inspections.
How do I request an appointment?
Tell us the property type, postcode/location and what you need. Holger Holling will agree the scope, total price and appointment with you. Enquiries are non-binding; a commission arises only after personal agreement.
Why repeat the assessment?
Like a service logbook: the initial assessment, findings, photographs, decisions, work and follow-up inspections are brought together for the property. An invoice records reported work; a new visual inspection is needed to describe the current visible condition.
Are follow-up inspections included?
No. Follow-up assessments have their own scope, appointment and price. No subscription arises automatically.
Is the documentation tamper-proof?
No. Dates and versions improve traceability, but do not guarantee immutable storage or cryptographic protection.
Who may carry out repairs?
You decide on the commission, timing and contractor: your usual plumber, an AquaRisk partner or another trade business. No repair contract arises automatically. Urgent hazards still require prompt action.
What does the QR code show?
A property-specific QR access can be agreed. It links the building’s label to its latest assessment, open findings, documented work, follow-up inspections and next recommended date. The physical label is not a permanent certificate of safety.
