If a burst or leaking pipe has caused the damage to your walls that is the first thing we will look at. Once the source of the water flow is cut off then the drying processes can begin. To speed up the process the area needs to be properly ventilated so all windows and doors must be opened. Wallpaper has to be removed as a lot of moisture can become trapped between the wallpaper and the wall itself. If mold has taken root then it needs to be cleaned off and we do that with special sanitizing chemicals. Special fans and heaters are directed at the affected walls and are used to dry them out.
