Water damage

Water Damage - Water damage refers to damage to a building’s structure, fixtures, or technical systems caused by uncontrolled water leakage or infiltration. Causes include burst pipes, faulty plumbing, leaky roofs, flooding, heavy rain, and sewer backups. Water damage is among the most common and costly types of building damage - in Germany, over 1 million cases of water damage are settled annually, with an average cost of approximately 3,000 euros.

Immediate Action and Damage Mitigation

When water damage occurs, quick action is essential: Immediately - shut off the main water valve or the affected section of the line; turn off the power in the affected area (risk of short circuit). Within hours - remove standing water (wet vacuum, pump), move soaked furniture out of the danger zone, notify your building insurance provider. Within 24-48 hours - hire professional drying services (industrial dehumidifiers, infrared heaters), document the damage with photos. Professional leak detection by a specialist company (using thermography, acoustic methods, or tracer gas) identifies the cause of the damage non-destructively.

Reporting the damage quickly is not only important from an insurance perspective-most building insurance policies require immediate notification (often within 24-72 hours). Anyone who delays reporting the damage risks a reduction in insurance benefits due to a breach of the duty to mitigate damage. Take photos of all visible damage before renovation work begins and, where possible, keep samples of the damaged materials.

Drying and Restoration

The drying phase is crucial for minimizing damage: Professional drying equipment reduces residual moisture in walls and floors over a period of 2-6 weeks. The cost is approximately 1,500-5,000 euros, depending on the extent of the damage. Without adequate drying, there is a risk of mold growth-at room humidity levels above 80%, mold begins to grow after just 48 hours. After drying, restoration begins: replacement of moisture-saturated insulation materials, subfloor, and wall coverings; repainting; and, if necessary, renewal of the electrical wiring in the affected area.

In cases of major water damage-such as a burst riser pipe connection in an apartment building-it often makes sense to have a damage coordination service provided by a specialized restoration company, which coordinates all trades (drying specialists, masons, electricians, tile setters) and acts as the point of contact for the insurance company. The costs for the coordinator can also be billed through the building insurance, provided this is stipulated in the contract.

Common Causes of Water Damage in Older Buildings in Nuremberg

Galvanized steel pipes are particularly common in existing buildings in Nuremberg dating from the 1950s to the 1970s. These corrode from the inside and cause leaks at screw connections, elbows, and shut-off valves. Typical damage includes pinhole leaks-tiny corrosion holes that initially release hardly any water but lead to significant moisture damage in walls over the course of months. We recommend that owners of older Nuremberg buildings have the pipes inspected by a professional plumbing company every 10-15 years and consider a complete replacement if signs of corrosion are found.

Practical Tip for Property Owners in Nuremberg

We recommend that property owners in the Nuremberg metropolitan area prepare for water damage: Check your building insurance for adequate coverage for water pipe damage (standard) and natural hazards (flooding, heavy rain - additional coverage required). Keep the number of a water damage emergency service and your insurance broker handy. For older existing buildings in Nuremberg with galvanized steel pipes (common in structures from the 1950s-1970s), we recommend regular pipe inspections-corrosion in water pipes is the most common cause of water damage.

Buyers of older buildings should explicitly ask about known water damage and its remediation during the building inspection prior to purchase. Water damage that has been fraudulently concealed-e.g., past damage behind paneled wall surfaces-can lead to the purchase contract being contested and to claims for damages. If in doubt, have a building inspector perform a moisture measurement.

Frequently Asked Questions

Who pays for water damage?

That depends on the cause: Plumbing water damage (burst pipe, defective fixture) - the owner’s building insurance covers the structural damage, while the tenant’s home contents insurance covers the damage to personal property. Flooding/heavy rain - covered only by natural disaster insurance. Damage caused by a neighbor (e.g., a leaky bathtub on the floor above) - the liable party’s liability insurance pays. In a condominium association (WEG): Damage to common property (pipes up to the apartment) is covered by the WEG building insurance; damage to the tenants’ individual property is covered by their home contents insurance.

As a tenant, do I have to notify the landlord?

Yes, the tenant is obligated to report water damage to the landlord immediately (Section 536c of the German Civil Code). If they fail to report it and the damage worsens as a result, they may be liable for damages. The landlord must have the damage repaired-the tenant may be entitled to a rent reduction during the repairs (20-100% depending on the disruption).

How do I prevent water damage?

Preventive measures: Regular maintenance of water pipes and fixtures (condition inspection every 5 years for older buildings), replacement of hoses on the washing machine and dishwasher (every 10 years), backflow preventer in the sewer system (mandatory for basements below the backflow level), water detectors in critical areas (laundry room, boiler room, under the sink - cost: approx. 20-50 euros/unit), and shutting off the main water line during extended absences (vacation).

How long does drying take after water damage?

The drying time depends on the extent of the damage, the building materials affected, and the technology used. Screeds and masonry dry significantly slower than wood or drywall. As a rule of thumb: 3-8 weeks for a medium-sized water pipe leak requiring screed replacement. Don’t rush-a wall that hasn’t dried completely under a fresh coat of paint will inevitably lead to mold. Residual moisture is checked with a moisture meter before restoration work begins.

What should be considered in the event of water damage in the common property of a condominium association (WEG)?

In condominium complexes, water damage often leads to uncertainty regarding responsibilities: Damage to common pipes (riser pipes, roof, basement) falls under the responsibility of the homeowners’ association and is handled through the WEG building insurance. Damage occurring within an apartment due to a defective section of piping that is part of the individual property is the responsibility of the affected apartment owner. In multi-family homes in Nuremberg built between the 1960s and 1980s, confusion regarding the exact route of the supply lines (which section is common property?) is particularly common. We recommend that condominium management companies immediately consult the pipeline layout plans for every claim and clearly assign the damage report to the correct insurance provider-unclear responsibilities delay settlement and increase the damage.
