The only effective way to permanently get rid of mould problems is by reducing the build-up of moisture in your home. This can only be achieved through better ventilation.
Mold can grow on or fill in the empty spaces and crevices of porous materials, so the mold may be difficult or impossible to remove completely. Avoid exposing yourself or others to mold.
Indoor mold growth can and should be prevented or controlled by controlling moisture indoors. If there is mold growth in your home, you must clean up the mold and fix the water problem. If you clean up the mold, but don't fix the water problem, then, most likely, the mold problem will come back.
When mold dries out and becomes temporarily inactive, it is considered “dead” mold. This happens when mold is killed, perhaps with bleach, but not removed. Dead mold appears flaky and powdery, unlike living mold that appears moist and grows in various colors, such as white, black, or yellow.
Homeowners can handle cleaning about 10 square feet (roughly 3 feet by 3 feet) of black mold on their own. If the patch is small enough, a combination of bleach, water, scrubbing, and ventilation should do the trick. Before treating mold on your own, prioritize ventilation and protective gear.
Cleaning vinegar, which contains 6% acetic acid, is the best type for killing mold. White vinegar containing 5% acidity will also work just fine. If you don't already have some at home, white vinegar can be inexpensively purchased at most grocery stores.
All contaminated surfaces will be vacuumed with a HEPA vacuum to trap the mold spores while releasing clean air, unlike traditional vacuum cleaners. Next, a professional will spray and wipe down the once contaminated surface with microfiber cleaning cloths.
Long-term mould exposure can cause severe issues that can last for a long period of time and may cause irreversible damage to the human body, so it is important to never ignore that bit of mould growing.
Moisture is one of the major conditions required by molds to grow and failure to cut off any sources of moisture or condensation may never solve the mold problem. Even if you remove the mold but your pipes keep leaking, you will only be creating room for new molds since nothing prevents them from growing.
If you don't eliminate the original source of the moisture, mold will certainly come back, even after using bleach!
One of the biggest issues is that the integrity of the wood and other materials could be compromised due to the length of time the materials have been wet. If you experience persistent mold, even in a small area, you should use a professional to remove black mold effectively.
When searching for black mold, look for circular-shaped spots that are black, dark green or dark brown. Some black mold can also take on shades of orange or have flecks of white within it. Most of the time, black mold has a slightly furry appearance.
Professional mold remediation typically costs $1,500–$9,000 with an average cost of $3,500. Bathroom mold removal typically costs between $500 and $1,500. Removing mold from an attic costs $1,000–$9,000. Basement mold removal projects typically cost $500–$4,000.
Both Concrobium Mold Control and hydrogen peroxide-bases agents remove mold with a high “kill rate.” They are highly effective at killing active mold growth.
Mold stays “dormant” in the air or on surfaces even when there's no excess moisture to help it grow. If the humidity in a room increases, mold will start growing in patches on walls, clothes, and more. So, to answer your question, dehumidifiers do NOT kill mold, but they do prevent it by reducing humidity.
Bleach can contribute to further mold growth
Bleach is made up of about 90 percent water. Moreover, since molds thrive with moisture, spraying bleach on mold can contribute to further mold growth, especially on porous (permeable) surfaces.
Hydrogen peroxide kills mold spore on contact by breaking down proteins and DNA. It's normally used to clean mold on porous and non-porous surfaces. Ionized hydrogen peroxide can kill mold spores in the air, but it requires the use of a special fogging machine.
Unfortunately, it is impossible to get rid of all mold spores in the air so you need to replace the air filter in your ac unit regularly. In addition, use an air purifier that contains a high-efficiency particulate air (HEPA) filter. These air filters are known to remove up to 99.7% of all mold spores from your air.
Black mold is a fungus that may cause your immune system to react. Common symptoms include sneezing, coughing, congestion and eye irritation. It rarely causes serious illness or death but may worsen asthma symptoms.
Any mold should be removed and the moisture source that helped it grow should be removed. There are very few reports that toxigenic molds found inside homes can cause unique or rare health conditions such as pulmonary hemorrhage or memory loss.
It is both easier and faster for mold to grow than you may think. Black mold can cause hay fever symptoms in healthy people and lead to severe respiratory problems in people with preexisting conditions.
Each person's body is affected by mold toxicity in different ways. Some experience constant migraines and headaches, shortness of breath, brain fog, fatigue or even depression. Since symptoms differ from person to person, they may not be quickly associated with mold exposure.
