Indoor air quality may have a considerable impact on your well being. This often neglected problem may result in severe consequences for your health. According to the guidelines on indoor air quality by the World Health Organization, the poor state of air in closed spaces contributes to morbidity and mortality.
One of the major air pollutants is mold. Although exposure to low concentrations is completely harmless, in greater quantities it can have harmful effects to both material and people. The duration of the exposure is also a factor.
Mold may cause allergies and in more severe cases asthma and infections. If this is not enough, it can damage your living space as well. Mold can destroy the walls of your home, harm your favorite books or wooden items, and it can spoil your food and clothes. If not treated, both your home and health can be significantly affected!
Below are several things you need to know about mold when buying or selling a house.
Mold: What Homeowners & Home Buyers Need to Know
Mold is a type of fungi that feeds on organic material and spreads across warm and humid surfaces. They differ from regular bacteria, plants, or other living things. They appear green, black, or blue when visible. The color depends on the type, the source of its nutrients, and the age of the mold colony…the type most often found in homes is mildew (white or gray in color). Mold reproduces by tiny spores and are impossible to see until the colony grows and becomes a noticeable problem.
There are both indoor and outdoor molds and an exact count of the various types is unknown. It is estimated there are hundreds of thousands of mold types in the world. These microorganisms prefer damp, humid, and warm areas. However, its spores are extremely resistant, even in dry and cold conditions. They are transmitted via air or water, and when the conditions are right, they will start growing and creating colonies. Mold can basically grow on anything that is organic.
The most common places where you can find it are basements, bathrooms, kitchens and laundry rooms, thus places with high humidity levels. If exposed to moisture, wooden and PVC paneling turn into a great environment for mold as well.
This winter, as the damp begins to increase in the intimate corners of your home, you may begin to notice little black patches that should not be there. These patches are mold patches, and can have all kind of implications on the appearance of your home and your health. Having mold in your home is a serious condition that needs to have remediation performed immediately!
What Type of Damage Can Mold Cause
When we think of household damage, we often think of the visible black mold that shows up on walls, ceilings, or in corners. When mold reaches problematic levels it can damage the structural integrity of your home, damage your household items, and present an overall unhealthy appearance for your home. If that was not enough, it also comes with unpleasant odors. Here are some of the prevalent places you may see mold in your home:
- Any damp area (around plumbing pipes, showers, etc.)
In addition, mold may have serious effects on your health. Sensitive people may experience an allergic reaction or an asthma attack. For those with weakened immune systems mold can cause severe respiratory or lung issues. Other symptoms include:
- Eye irritation
- Shortness of breath
- Sinus issues
- Skin irritations
- Sneezing fits
Ways to Prevent or Reduce Mold
In general, you can’t eliminate mold and its spores for good, but you can limit their presence. If there is already mold growing in your house, clean it and remove the source of damp immediately. It’s important to eliminate both the problem and the cause, in order to prevent new occurrences. Controlling the factors below that help produce mold will help you control its growth!
- Reduce moisture – The key to keep mold at bay is moisture control. It should be no higher than 60%. If you have an overall existing problem with moisture in your home, consider buying an air conditioner, dehumidifier, and certainly use fans when necessary. The moisture level in the atmosphere changes in the course of the day, as well as the air temperature. This means that you need to measure these more than once a day in order to undertake adequate actions.
- Reduce water leaks – If mold was not a reoccurring problem and only showed up recently, maybe there are leaks in your plumbing, roof or walls. Make regular checks to ensure that your home is in good condition. If you stumble on leaks, fix them immediately before the problem aggravates.
- Reduce condensation – Condensation occurs when evaporated air cools down and turns into liquid. This is what causes mold to appear on walls and wallpapers. One way to reduce condensation is by keeping the rooms warm. Another way is to insulate surfaces that get cold (pipes, windows, etc.)
- Reduce humidity – Humidity is difficult to control and is affected by the environmental factors. Ventilation is a great prevention tactic. Keep the windows open during the sunny days. Start using your exhaust fans, air conditioners and humidifier, especially while cooking or cleaning the house.
- Bring sunlight – Mold is unable to survive in warm and dry conditions. Bring as much sunlight as possible into your house, while keeping the humidity at low levels.
- Use common sense – Completely dry all carpets, clothing, and upholstery. If items such as books or wood get wet, ensure they are wiped down and dried as well. When storing your belongings, ensure there is no visible mold before boxing your valuables up.
Testing for Mold
If mold is already visible, there is no logical reason to test for it. In addition, there are currently no government mold standards so hiring someone to determine if your property is mold compliant or if mold levels are in an acceptable range is a waste of time and resources.
However, if there was a severe mold infestation, and both remediation and cleanup have occurred, there may be limited instances where you may want to hire a qualified professional to ensure the mold cleanup was complete. It is important to remember, without established control and standards, acceptable mold level test results is open for interpretation.
How to Get Rid of Mold
In general, mold can be cleaned with commercial cleaning products such as soap and water. Expensive detergents will also do the job. Removing mold is not a rocket science. What you need is the right cleaning product, a whole lot of scrubbing (preferably with a soft brush), protective eye and skin wear, and ventilation to ensure you are breathing clean air.
You can prepare your own eco-friendly cleaning solution using 3 parts vinegar to one part water. Another popular method is using bleach. Contrary to the common perception, bleach only works on non-porous materials (bathtubs, counter-tops, glass, etc.). Bleach is unable to penetrate into porous materials (drywall, wood, etc.), and although the surface will be clean and free of mold, it will quickly return as it is still growing inside the porous material.
In the case of mold, prevention is better than cure. Ensure proper circulation throughout your home by keeping windows open each day to reduce the risk of it developing. Keeping areas that receive minimal light dry can also stop its development. If you suspect you have a minor mold problem, cleaning the mold off with a special cleaner, and painting over the area with mold-proof paint can rid yourself of the problem. In severe cases you may need the help of professional cleaners, to remove the mold problem and give you back your house and health.
