My neighbour has flooded my flat - what shall I do? How to dry damp walls?

If you have ever been flooded by a neighbour or a riser pipe has burst, you are well familiar with the consequences of such an occurrence. Firstly – damage to the flat, i.e. wet walls and the omnipresent, unpleasant smell of dampness. Secondly, a long road to receiving damages from the insurance company. Thidly, the prospect of expenses connected with repairing the damage and flat renovation.

Something like that happened to Elżbieta. A faulty water valve was noticed only after damp patches appeared on the walls. It turned out that water might have been leaking for a long period of time. Elżbieta started to worry when a damp patch appeared on a wall at the end of November 2010. At first, she thought it was due to ineffective heating, but the patch grew larger every day. When finally experts discovered the faulty water valve at her upstairs neighbour, the patch was 1.5 m high and approx. 0.5 m wide. Additionally, there was an intense smell of damp and fungus in the room and plaster began to flake off the wall.

Elżbieta could not start renovation before the completion of the loss adjustment procedure. However, experts advised her to use a dehumidifier to dry the walls in the meantime.

A condensation dehumidifier DH 721 was placed in the 10 m² room (see the adjacent photo). It is a typical model intended for dehumidifying smaller areas. This dehumidifier working for a few hours every day collected 25 l of water over a week. The wall began to dry and, more importantly, the unpleasant smell of dampness disappeared. To prevent subsequent dampening by the remaining water dribbling down from upstairs, Elżbieta used the dehumidifier every 2-3 days all day long. It is surprising that even after a month’s operation, the dehumidifier collected another 5 l of water. This shows how much water must have flooded Elżbieta’s flat for several days.

Although the flat owner is still waiting for major renovation of the room, she is pleased that she has succeeded in avoiding fungi growth and that the wall has not been damaged permanently. A dehumidifier turned out to be an ideal way out of the difficult situation. It should be mentioned that it would be difficult to dry the wall using only the heating system. At very low winter temperatures outside reaching up to -15°C, it is simply impossible to dry walls the natural way. On the other hand, if Elżbieta had waited for warmer days, harmful fungi would certainly have developed on the walls until that time. The dehumidifier managed to remove all dampness from the wall in a relatively short period of time, simultaneously preventing unpleasant consequences of the faulty water valve leak. The wall is dry now (February 2011) and renovation works can be started.

Dehumidifiers also work well for damp or flooded cellars and garages as well as houses affected by flooding. A broad range of Master dehumidifiers is available, so everybody can select devices according to their needs – the size and type of facility and the extent of damage. Selecting the right model guarantees the effectiveness of the drying process as well as their efficient operation.
