D&M Home Inspections

Most houses don't have this amount of mold (this is a living room ceiling).

However, It is impossible to completely eliminate all molds and mold spores indoors. Mold will always be found floating in the air and in house dust. Indoor mold growth can be prevented by controlling water and moisture indoors. Indoor humidity should be kept between 35% and 50%.

If there is mold growth in your home, you must clean up the mold and fix the water problem. If you clean the mold but do not fix the water problem, the mold will grow back.

All molds require moisture for growth. Most molds cannot start growing until the temperature reaches 39 F (4 C.) Some molds use the humidity in the air as their only water source; other molds need more moisture. Stachybotrys for instance, known as the black mold, needs a constant supply of water to continue to grow.

In a home, mold is a quantity problem. A little mold is easily removable and should not be a big concern. Mold spores become a problem when there is unchecked growth in your home. Mold spores are small, can pass through the normal respiratory tract, and are drawn deeply into the lungs, leading to difficulty with breathing and allergic reactions.

If there is mold growth in your home, you must clean up the mold and fix the moisture problem. If you clean the mold but do not fix the moisture problem, the mold will just grow back.
