There are instances where microbial growth can be hidden. Especially here in Hawaii. The climate on the island is a perfect petri dish for microbial growth to grow quickly. The humidity and consistent temperature provide a perfect incubation environment for spores to root and grow. In this picture, you can see the backside of wallpaper. The wallpaper backing is full of adhesive which is a perfect food source for mold. The wallpaper itself acts as a moisture barrier trapping the humidity between the wall and the open-air space. This is a prime example of how growth can go undetected for extended periods of time. When considering cutting into a wall with wallpaper or removing the wallpaper to freshen up the look of a room, always consider the possibility of growth on the backside. If growth is found, don't hesitate to call the professionals at SERVPRO immediately to reduce cross-contamination. The professionals at SERVPRO will set up mitigate the mold by setting containment which will stop the mold spores from spreading through the property making the renovation safer for all.
