Moldy MDF Boards
Mold will grow on and inside the porous MDF board
It is possible for medium density fiber (MDF) board to promote mold growth anywhere in your home including your sub-floor.
With enough water and time the semi porous fibers and glue begin to expand and allow mold to grow on and in the MDF board. If recognized during a mold inspection, a certified mold inspector may recommend that the building materials have to be removed and replaced. In this case, the mold inspector may have recognized that the overall integrity, moisture level, and composition of the materials have been compromised. It may seem odd and peculiar but mold growth may be in between the layers of wood. Water damage causes the materials to expand and create gaps. This space in between the material promotes the growth of mold. It soon becomes a dark and moist area for mold to thrive.
Items currently made of MDF board in your home may include your baseboards, bathroom cabinet, dressers, kitchen cabinets, crown moldings, window moldings, exterior plywood, and even the sub-floor.
Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming panels by applying high temperature and pressure. MDF is generally denser than plywood. It is made up of separated fibres, but can be used as a building material similar in application to plywood. It is stronger and much denser than particle board.
The name derives from the distinction in densities of fibreboard. Large-scale production of MDF began in the 1980s, in both North America and Europe.
Prevent water damage and mold growth
Leaves, sticks, and debris can become a problem for your rain gutters. Rain gutters typically allow the removal of water away from your home or building. In this instance, the blockage within the rain gutter allowed water to overflow and deposit near the front door of the unit. If left untended, the backup within the gutter would allow the water to impact the structure and possibly cause water damage inside the home. Water damage and mold growth inside your home can be prevented by regular maintenance of the rain gutters during this El Nino rainy season.
Do your best to observe the signs of a failing rain gutter and prevent water damage:
- Loose or detached down spouts
- Bent or broken sections of the main gutter
- Excessive debris (including leaves and dirt)
- Improper slope and grading of the gutters
- Overflowing water
