Mold & Black Wood Damages From Condensation on a Window Sill
Wood is a porous substance that absorbs moisture like a sponge. Repeated exposure to wet conditions will cause mold spores to flourish and grow and make wood discolor. The black coloring is indicative of the mold in the grain of the wood and over time the fibers will soften and can rot. The first step to eradicate the mold is to pinpoint the cause of the moisture. On cause is condensation, which occurs when you have a hot shower and the warm moist air contacts a cold pane of glass. This causes dripping just like a frosted glass of beer on a hot summer day. Does this Spark an idea?

Molds

There are two types of mold which affect wood. Mold fungus does not harm wood and is the source of the greenish-blue coloring. Mold decay is present as the black and sometimes slimy pigments in the wood. Mold is one of the simplest forms of plant life. Mold spores are carried in water and air. They are like most plants and need moisture to grow, so moisture needs to be dried out of wood within 24 to 48 hours to prevent mold blooms.
Mold Problems
-
The type of mold determines the level of discoloration involved in the wood. Black molds are the most dangerous because they will decay and rot wood. The greenish-blue mold is responsible for the dry mold spores but is not damaging to the wood. Either way, the mold poses a health hazard for people with respiratory issues and allergy sufferers. Additionally, molds concealed in wood begin to decay the wood and eventually the window sill will have to be replaced. Begin the cleaning process immediately to prevent further damage and set up a plan of action to discourage the formation of mold.

Discouraging Mold
-
Mold can't blossom without water. Condensation on windows means that there is a meeting of the warm air inside and the cold air outside. To prevent this, storm windows or new double paned insulated windows can be installed. In the bathroom, a ceiling fan will suck out much of the moisture and a heat light will help dry out the area. A fan or dehumidifier can be installed in any room with a moisture problem to increase air circulation and help keep the air dry.
Treatments
-
The most effective treatment to remove mold is bleach. A simple solution of one part bleach to four parts water will kill the mold spores. The area needs to be thoroughly dried after cleaning or mold spores in the air can land and start the problem anew. Persons with allergies should wear a mask to prevent inhaling mold spores when cleaning. The bleach treatment not only kills mold spores but also will remove some of the discoloration to restore the look of the wood.
