Mold in the home can be more than a nuisance, it can also cause allergies or other respiratory problems. There are a few key locations in most homes that are most likely to harbor mold, so regular inspections of these areas can ensure problems are caught early enough for easy removal.
1. Attics and Ceilings
Attic and ceiling mold typically originates from one of two issues—a roof leak or poor roof ventilation. Not all roof leaks are catastrophic. In some cases, a slow leak can go on for many months without being noticed below, but the moisture will still accumulate and lead to mold growth. Poor ventilation also leads to slow damp accumulation due to moist, warm air from inside the house becoming trapped in the attic.
2. Damp Basements
Basements often harbor mold, thus their reputation for musty odors. The cause can be moisture from periodic flooding, or it can be due to slow moisture seepage through the slightly porous concrete walls. Sometimes the cause is trapped moisture that is put out by appliances, such as the dryer in the basement. Regardless of the cause, it must be addressed and the mold removed.
3. Plumbed Walls
Not every wall in your home will be prone to mold growth. The most at-risk walls are those that have plumbing pipes and water lines running through them. Leaks in the pipes can lead to moisture accumulation and mold growth. If a pipe bursts, then it's vital that the inside of the walls are dried out quickly and treated for mold. Moisture may also accumulate unnoticed, such as from condensation buildup on pipes or slow leaks that aren't immediately visible on the outside of the wall.
4. Near Appliances
Certain appliances can increase the chances of mold growth around them. For example, a leak from a dishwasher or ice maker line may be minor enough that you never notice, but the water can accumulate under the appliance and lead to mold growth in the floorboards below. Condensation from toilet tanks or hot water heaters can also lead to damp conditions and mold in the surrounding structure. The cabinet under a sink is also a likely origin of mold.
5. Floor Coverings
You don't always need a leak or a flood for mold to grow. Carpeting is very prone to mold growth if you live in a humid or damp climate, for example. The mold in the carpet can even penetrate into the wooden floorboards below, making the problem even worse. Mold is also common on the floors of kitchens and bathrooms due to moisture seeping underneath linoleum or tile.
