What You Need To Know About Mold



Mold needs water to grow, so it will thrive wherever there is a food source exposed to any moisture.  If a home has been flooded, mold will grow on anything water soaked such as carpeting, clothes, furnishings, books, etc...  Usually within 24 hours of the floodwaters receding.


Anywhere that water enters your home, you have the potential for damage.  Any place in your home that is subject to constant moisture, condensation or steam such as unvented bathroom condensation, are ideal conditions for mold to grow.


You should thoroughly inspect your home if you see any of the telltale signs of water damage, such as musty odour, wallboard or wallpaper staining near a window, or plaster or drywall that crumbles or swells up.


There are several ways to reduce the indoor humidity such as increasing ventilation by using exhaust fans when cooking, washing or cleaning.  Using HRV’s (Heat Recovery Ventilators), air conditioners, venting bathrooms, laundry rooms and other areas that exhaust moisture to the outside can reduce humidity.  Adding insulation to exterior walls, windows, pipes, roofs and floors, can also prevent condensation.


Dehumidifiers may be used to reduce moisture levels within the home, but they require the emptying of water buckets and cleaning maintenance.  The cost of operating a dehumidifier can exceed the cost of the most expensive kitchen appliances like the refrigerator.


NOTE:  Some Homeowners use “Swamp Coolers” for cooling air in the home during the summer days.  Remember, these are humidifying as they are cooling.  High humidity causes mold unless exhaust vented to the outdoors.
