Mold growth is no laughing matter. It can do damage to your home as well as to your health, so you should do what you can to prevent mold from taking hold. Your bathroom will be one of the areas where you are most likely to have to deal with mold. This is because of the high moisture content that you have in that room, as well as the chance of wet clothes and towels being left on the floor (this is a big no-no by the way).
Something that is vital to keep your bathroom mold-free is a good exhaust fan. This will move humid air outside your home to keep it from providing fertile growing conditions for mold spores.
Fixing leaks in your bathroom and cleaning up spills should be of high priority for you. The longer water is sitting on your floor, the more likely you are to have issues, which is why it’s important to take care of problems as soon as they pop up.
