Have you recently spotted black, clustered growths in your bathroom, around your toilet or shower, in your kitchen, or in your basement? Have you been coughing or sneezing when you enter particular rooms?
Your home could have a black mold problem that may need immediate attention.
Black mold or Stachybotrys chartarum is usually accompanied by a distinctive odor and is greenish-black in colour. It is one of the most toxic molds that can be found in homes as it produces toxins called mycotoxins, which are capable of causing health problems in humans.
How fast does black mold spread?
Mold begins to grow as soon as its spores land on a damp, fibre-rich material (wood, fabric, drywall…) and it can spread around the house within 24 to 48 hours. It colonizes in one to twelve days and grows at one square inch per day. In less than a week, it can cover surface areas of several square feet.
Unfortunately in most cases, mold is widespread and already a big problem before a problem is even suspected by the homeowners.
How fast does mold grow on walls?
It doesn’t take too long for mold to grow. It can start spreading on walls within 1-2 days.
Where else does black mold grow?
Any moist surface is susceptible to mold. The surfaces that commonly support the growth of black mold, include: drywalls, paper and paper products, floor boards, cardboard, insulation materials, wallpapers, carpets, furniture, ceiling tiles, fibre-board, gypsum board, dust, fabric, and upholstery.
How does black mold form?
The main reason behind the formation of black mold is moisture, which can be caused by several things, such as, water leakage, lack of proper ventilation, flooding, irregular maintenance, humidifiers, condensation, clogged-up gutters, damp clothes, humid basements, or even water accumulation around the foundation of your house.
Can black mold spores travel in the air?
Yes. Mold spores are airborne and can attach themselves to people’s skin, clothing, shoes, shopping bags, furniture, carpets, and even pets. Once spores enter your home, they can settle onto any surface and start to multiply. They can also enter your house through open doorways, open windows, and HVAC systems.
Mold spores are microscopic and are virtually found everywhere. They are naturally found in the air we breathe, both indoors and outdoors. Since spores are tiny and lightweight, they become airborne easily, every time we vacuum or walk on the carpets or even sit on our couch.
Can black mold spread from house to house?
Yes. If you have had mold in your old house and you’re moving into another space, it is possible to cross contaminate this new environment.
Because mold spores are not visible to the naked eye, it is hard to tell which surfaces are contaminated. Therefore, the mold has to be completely cleaned before you renovate or move to a new home.
What is the best temperature for black mold to grow?
Mold usually thrives in warm, humid conditions. Temperatures around 70 degrees Fahrenheit or 20 degrees Celsius are ideal conditions for mold to grow and multiply.
Can black mold grow in the winter time?
Cold, wet and freezing conditions during the winter months is also a good time of the year for molds to multiply. Mold is often found near sources of water where it easily grows and reproduces.
How to tell if your home has black mold growth?
Mold can quickly become a huge problem before any major signs of damage are visible. But the good news is, you can prevent and minimize the threat of black mold in your home by recognizing the signs — the earlier you do, the lesser the damage.
No matter if they are current or they happened in the past, moisture is often the cause behind black mold. Leaky pipes, faucets or toilets, window condensation, recent flooding, etc. – all of that creates enough moisture for mold to develop in your home.
High level of humidity
Mold, including black mold, is often related with high levels of humidity. An optimal humidity level would be between 30% and 50%, and anything above that is considered high, which is a perfect atmosphere for black mold, as well as any other type of mold, to develop and grow in your home.
Discoloration of walls and other surfaces is a big tell. Yellow water stains on walls are often followed by black mold spots. Even cracked or peeling paint, bubbling, and bulging are signs that there is moisture in or behind your walls.
If you cannot see or spot mold growth, you should be able to smell it in the air. Black mold has a specific musty, earthy smell. You should be able to pick up the scent, especially in closed-off areas such as basements or attics.
People living with black toxic mold in their homes could be susceptible to upper respiratory tract symptoms such as coughing, sneezing, wheezing, fever, shortness of breath, runny nose, red or itchy eyes or skin, rashes, and other allergic reactions.
Black mold is known to cause reactions in people who already have asthma. Other possible health-related issues related to mold exposure include: fatigue, persistent headaches, dizziness etc.
What makes black mold a threat is that its spores can be easily inhaled by humans. Those with already weaker immune systems, such as infants and seniors, could particularly be at a risk of being infected.
There are several more risks associated with black mold aside the health risks. As it spreads, black mold can destroy your personal belongings, cause severe structural damage to your house and compromise your overall quality of life.
How to prevent mold growth?
Conducting routine home inspections and maintenance are the best ways to deal with a black mold problem. Keep an eye out for evidence of water damage and visible mold on a regular basis. The conditions that cause mold should be corrected in a timely manner to prevent mold from growing further.
The extent of structural damage black mold can cause to your home, depends on how quickly you act to fix it.
Some of the ways you can keep mold out of your home is by:
- Controlling humidity levels. Relative humidity inside your home should never be higher than 50%. On excessively humid days, using air conditioners, ventilation systems or dehumidifiers can help control humidity.
- Managing day-to-day moisture in your home.
- Ensuring adequate ventilation in kitchens and bathrooms when cooking, showering, cleaning, etc.
- Using mold inhibitors.
- Cleaning the house regularly with anti-mold cleaners.
To completely get rid of black mold from your home, you must address the root cause of the problem, so that there is no recurrence of mold. For example, just cleaning up the mold without addressing the moisture problem will not solve the issue because the mold will very likely return.
