Mold can grow all over the house but there are a few rooms that are a bit more at risk for mold growth than all the others and this is usually due to the amount of inherent moisture that passes through them on a day to day basis. You may not realize it if you are just moving into a home of your own after college or getting out of your parents house, but the kitchen and the bathroom are the two areas of the home that require the most attention to keep them in tip top shape over the years (or just months) you will be living there.



All surfaces in your bathroom that are porous are in danger of mold growth, which is why you never want to install a porous flooring material in this room. Materials like hardwood or carpet are very bad for this and other wet rooms of the house like the kitchen and laundry room, so installing something like ceramic tile or sealed stone is going to be much better. Even if you install these hard materials, you can still have problems with mold and water damage underneath them if they are not sealed properly.

You should check regularly for missing areas of caulking or grout, since this can allow water to get to the wooden subfloor and cause it to rot. You also need to check for this in the kitchen, since the same problem can come up. You can help prevent it, though, by installing Schluter-Ditra before you put the flooring material in. This is a layer of waterproofing material that will give you an added level of protection against water damage and mold growth.

Another problem appears on the ceiling if there is no vent or fan to allow the steam and heat from the room to escape to the exterior of the house. The ceiling will absorb this moisture since it has nowhere to escape to and will become waterlogged. Mold starts to grow on wet surfaces like this in a relatively short period of time, so making sure that the steam created by the bath or shower gets out is very important.

This is also a problem in the kitchen when there is no exhaust system over the stove. You can fix this in both of these areas and other areas of the home with high humidity by installing an exhaust fan that will pull it out of the room with the flick of a switch.
