Close insurance gaps in advance

If a water damage has occurred, and the insurance is to pay, it is too late. A value adjustment of the household should be made in any case in time to have to accept no loss in case of later damage. Tips can be found in this post.

Adaptation often missed

In the course of time, at home, one constantly creates new appliances, buys new furniture or furnishings and thus increases the value of so-called household effects. Often is also rebuilt or grown.

However, many miss the regular message to the insurance on the change in the budget, which is always an increase in value. The consequence is that the insured is underinsured at the time of the loss, sometimes with grave consequences.

In case of water damage, the following insurance applies:

  • Household
  • Home Insurance
  • Liability insurance

Responsibility of the individual insurance

Damage to the building and to the building fabric (floor, ceiling, walls) is the responsibility of the homeowners insurance. If you own a homeowner, you report that to your own insurance company.

If you are only a tenant, the homeowner is the insured in the homeowners insurance. He must report damages to his insurance company. As a tenant you have no influence on a possible underinsurance of the landlord, but may have to bear the consequences.

All damage and destruction of furnishings and objects in the apartment is reported to the house contents insurance. It is especially important to make sure that you are not underinsured.

The liability insurance must always provide, if the own water damage affects the property of others. This can be adjacent buildings, but also objects and household items in neighboring apartments. In addition, the liability insurance also regulates all damages that are not covered by the household contents insurance.


The legal basis for underinsurance includes § 75 of the Insurance Contract Act (VVG).

Underinsurance in homeowners insurance

For homeowners insurance, underinsurance always exists if the residential building has a considerably higher value than agreed with the insurer as the sum insured.

For the building value, the valuation is based on the so-called valuation 1914. For this is either estimated by an expert, or calculated according to living space and equipment features.

A calculation based on converted space or a conversion formula calculated from the acquisition costs. For this, the so-called construction price index is used. If the value calculated in this way no longer corresponds to the actual value of the house, there is underinsurance.

However, anyone who has a waiver of a waiver clause is usually on the safe side. A review after modifications and renovations and possibly a recalculation but makes sense in any case - for example, even after the installation of a photovoltaic system.

Underinsurance in household insurance

Even with insurance contracts in the household insurance, there are some contracts a Unterversicherungsverzicht. Here too, however, one must always make sure that the maximum sum insured actually corresponds to the total value of the household effects.

Without sub-insurance waiver in the contract, the value of the items is determined individually via a list. New purchases or additional purchases often lead to a higher value of the household than stated at the time the insurance was taken out. The insurance will then only pay for the damage in proportion to the damage:

Actual compensation costs = (amount of damage x sum insured): insured value

index adjustment

Usually there is a so-called index adjustment. According to the consumer price index, not only the premiums but also the insurance sums are adjusted to the same extent. In most cases, however, the index adjustment does not adequately cover additional household values.
