Whether old or new, mold growth is a problem in many houses. Nobody should live in moldy apartments for a long time, because mold can impair their health. Mold growth can only be combated effectively if the cause is identified and eliminated.
How dangerous is mold?
Molds are found everywhere in nature. Their spores and metabolic products fly through the air and are initially unproblematic for healthy people. If they are inhaled in high concentrations, they can cause problems in the respiratory tract. Some people also show various allergic reactions. According to the Federal Environment Agency, it is unclear from which concentration mold substances in the air we breathe lead to impairments. Therefore, mold should be removed as a precaution.
I.e. If you are living in Hermosa Beach, remove your mold with mold abatement Hermosa Beach service.
How does mold develop?
Mold needs moisture, they prefer to grow on surfaces that are permanently damp. Interior walls of intact residential buildings should be too dry for this. If mold does form, the cause of the damp wall must be determined. Possible causes include:
- leaks or cracks through which water enters from the outside
- cold spots due to poor insulation (thermal bridges)
- broken water or sewage pipe in the wall
- too high humidity in the room
What helps against mold?
Mold often forms under the wallpaper and initially remains undetected. If mold is visible, the stains should be removed as soon as possible. According to Jörg Huber, energy consultant at the Hamburg consumer advice center, you can treat areas up to about the size of the palm of your hand yourself. You should wear protective gloves and a respirator.
Remove the moldy wallpaper and dispose of in the trash. Treat the affected area with an anti-mold agent according to the instructions for use. Alternatively, wash the affected area thoroughly with high-proof alcohol from the pharmacy or denatured alcohol. Ventilate the room well during this and afterwards. Repeat the treatment with alcohol and white spirit when the wall has dried. These measures usually only help for a short time if the cause of the mold has not been identified and eliminated. Vinegar and vinegar cleaners do not work against mold.
How to prevent?
Residents can effectively prevent mold if they control the humidity in the apartment and ventilate it sufficiently. A hygrometer helps, which measures the humidity and displays the value as a percentage. It should be somewhere between 40 and 60. Measuring devices are available analog with a pointer or digital with a numeric display at prices starting at around ten euros. Apartments in which new, tightly closing windows have been installed must be aired much more frequently than before. More tips to avoid mold:
- Do not place furniture such as cupboards or sofas close to external walls
- Open bathroom window after showering
- also lightly heat unoccupied rooms and apartments in winter
- Keep doors to rooms that cannot be heated closed
How can you prevent mold in your home?
A structurally intact building, into which no moisture penetrates from the outside, is a prerequisite for healthy living. Proper heating and ventilation help prevent mold growth – with regular removal of moisture to the outside. Thermal insulation measures can reduce the problem of thermal bridges with cold wall temperatures. However, if tightly closing windows are installed during an energy renovation, you have to ventilate more intensively in order to reduce the humidity in the room and thus the risk of mold.
In the event of accidents (e.g., burst water pipe, flooding), it is important to dry the affected materials as quickly as possible to prevent mold growth.
Molds are found everywhere in the environment. They are undesirable in apartments. Massive mold infestation there can lead to irritation in the respiratory tract and to allergic reactions. Mold clearly does not belong in the apartment. The cause is always increased humidity. The brochure shows how mold infestation occurs, how high the risk of mold infestation is for residents and what can be done about it. Tips are also given on what you can do to prevent mold from developing in the first place.
Special cases new building and basement
In newly built houses there is still a lot of moisture in the walls, but at the same time the buildings are particularly airtight. It takes several years for them to dry completely. During this time, the room must be aired particularly frequently to prevent mold from forming. Windows and doors of basement rooms should only be opened in summer when the outside temperature is lower than the room temperature. Otherwise, the warm air will bring moisture into the basement, which will condense on the cold walls and objects and promote mold growth.
