Do’s and don’ts of mold removal and remediation

Before diving into the dos and don’ts of mold removal, we must understand what mold is and why it is hazardous. 

Mold is a type of fungus that lives and thrives in warm and damp environments. This nature of mold makes bathrooms, basements, and kitchens common breeding grounds. It can manifest itself on wood, drywall and also fabric. It spreads through airborne spores and can quickly grow on surfaces causing structural damage and triggering respiratory issues including allergic reactions. It can severely affect pets’ as well. Sometimes these health issues can manifest later in life. Mold growth can be hard to notice since it originates in shady places or around leaky pipes and roofs, which most people don’t see. Since mold proliferates quickly, it’s usually a full-blown infestation before anyone notices it. 

Now that we understand what mold is and what threats it poses, let us look into the dos of mold removal and remediation. 

The do’s of mold removal and remediation 

When it comes to mold removal it is imperative to approach the area with care to ensure safe and effective mold removal and remediation. Following are some tips to properly remove mold:

  1. First it is important to ascertain if the problem is mold or not. Mildew is also a fungus that resembles mold but mildew is a surface fungus. Hence with a good cleaner and some scrubbing, it can be removed. Mold is embedded in the surface on which it grows. It tends to be fuzzy or slimy in appearance. It is typically green or black whereas mildew is white, gray or yellow and has a powdery look to it. According to the EPA (Environmental Protection Agency) mildew is what one will find on the shower walls, around the windows, and other places which are high in moisture. Whereas mold can live on any organic matter including clothing, ceilings, walls, wood, paper, and leather.
  2. If it is molds, deal with them as soon as possible because once the growth starts, it spreads rapidly. Before you know it, a small mold problem becomes a large issue to be tackled as an emergency. Get the mold tested to know what type of mold it is and how to approach the problem. 
  3. The primary step to remove mold is to identify the source and address the source of moisture that is fueling the growth. Unidentified sources can lead to the recurrence of the problem or worsening of the existing problem. This step could include fixing leaks or improving ventilation. Sometimes it is difficult to identify the source. In such cases it is better to contact professionals offering mold removal services like Delaware Waterproofing.
  4. If you are moving to a new home or looking for a new home, identification of mold or the possibility of mold growth is important. Look for any discolouration or dark spots on the walls and fixtures near air conditioners, windows, refrigerators, faucets and other water-prone locations. 
  5. Protect yourself while removing mold. Always wear protective gear including gloves, goggles and a respirator to prevent exposure to the mold and hazardous chemicals. Unprotected exposure to mold can result in a wide array of diseases and can even cause death therefore it is essential to wear proper protective gear. 
  6. Contain the area and seal off the whole affected area with plastic sheets. This contains the growth and prevents it from spreading to other areas. The area should be well-ventilated, with open windows and fans as this helps in containing the spread of mold spores. 
  7. Mold removal should be done with proper cleaning techniques. Depending on the surface, the intensity and the affected area, appropriate cleaning solutions and methods like scrubbing with the right detergent like specialized mold removal products. Such things are better handled by professionals like Delaware Waterproofing who use the best mold removal products in Wilmington DE.
  8. Disposing of all contaminated materials like wood, tables, carpets and drywall is important. Even a tiny leftover material can trigger the whole thing to come back. Safely dispose of materials that cannot be cleaned or salvaged. 
  9. After cleaning, dry the area thoroughly. Make sure there are no wet spots as it can trigger the mold to return. Use fans, dehumidifiers or natural ventilation to fasten the drying process.
  10. DIY mold remediation is a risky task if you do not know what type of mold you are dealing with. Any type of mold is harmful to health, however, molds like black mold can escalate quickly and have a harsh effect on health. One wrong step can lead to unfortunate consequences. Therefore, seek professional help for this tricky process. You can contact Delaware Waterproofing, a one-stop destination for all your mold removal and remediation needs. Why get your hands dirty when they can do so for a minimal fee? 
  11. If you are a tenant, recognise your tenant rights. Most states have a legal doctrine called the “Implied Warranty of Habitability.” According to this, the landlord must maintain their rental in a liveable condition. Therefore, your landlord may be legally obligated to resolve the problem. Consult your lease and then connect with your landlord. Document all mold proofs well. Take videos and photos of the infected areas. If any issue has been reported, keep a copy of the letter and responses from your landlord.
  12. Consider buying a dehumidifier. As mentioned before, mold thrives in a humid atmosphere. Spores can be inhaled into lungs or land on food and be ingested. A dehumidifier can dry out the air and create an undesirable environment for mold, preventing its spread. Humidity levels should not exceed 60% inside your home.
  13.  Have a proper HVAC ( Heating, Ventilation and Air Conditioning) system. Make sure the ducts and the pipes are cleaned regularly. This helps in circulating fresh and clean air around the room. 

The don’ts of mold removal

Improper way of mold removal can result in catastrophic consequences. Even small amounts of mold can indicate larger issues with water damage. Ignoring this can lead to health problems and other issues down the line. Therefore, it is important to know the don’ts of mold removal:

  1. Do not use bleach. Bleach can kill mold on non-porous surfaces, however, it is not effective on a porous material like wood or drywall and can contribute to further mold growth by adding moisture. 
  2.  Avoid disturbing the mold. Engaging with the mold can release more spores into the air and increase the issue. 
  3. Don’t overlook the hidden areas. Check less frequently visited areas like the basement, under the carpet or the windows every now and then to check if there is any mold growth.
  4. Don’t attempt any DIY remediation for extensive mold growth. If the mold growth is more than 10 sq feet or if you’re dealing with toxic mold like black mold, it is recommended to seek professional help. 
  5. Don’t skip any inspection or testing as this helps in understanding what type of mold you’re dealing with. As mentioned in the previous point, mold like black mold is toxic and needs professional help. Consider hiring a certified mold inspector to assess the situation and perform testing if necessary, 
  6. Never paint over mold. You have to properly remove mold so that it never comes back, painting over it is not a solution. Many companies sell “Killing paint” which is not a good option. What mold removal paint does is, it suffocates the mold spores and prevents you from seeing anything on the surface. It does not kill the mold, only hides it. Mold will thrive in spaces where there’s moisture and humidity, so tackling those issues at the root is your first defense. 
  7. Never overlook safety. Not all molds look the same and the intensity of toxicity can not be measured without professional testing hence precautions are the best. Wear respirators and protective gear to help. 
  8. Avoid direct contact with mold. It is dangerous, not only can it cause health problems but you can also become a carrier. 
  9. Do not sniff it. Mold does not have a smell and inhaling mold can be detrimental for your health, especially it can impact the lungs.  
  10. Lastly do not use HVAC (Heating, ventilating, and Air Conditioning) if there is any suspicious existence of mold. HVAC systems prevent mold growth. But neglected maintenance and poor hygiene of the systems can be harmful and promote mold growth. Activating your HVAC system without proper cleanup may disperse spores all across your home.
