Mold Remediators Gone Wrong

Are you having trouble choosing a mold remediator for your home? Doctors James Schaller and Gary Rosen have put together in their book “Mold Illness & Mold Remediation Made Simple,” a list of humerous ways to know if you have a “bad” mold remediator :

You Know You Have the Wrong Remediator When..

  • He laughs when you ask if he has a contractor’s license or a mold remediator certification or license.
  • You ask if he has at least one million dollars in contruction or mold insurance, and he falls on the ground convulsing with laughter. Take him out in a wheel barrow and dump the clown =).
  • He has no clue or concern about fixing the source of the moisure. He does not realize ignoring the source of the moisture problem will mean the mold can always come back.
  • He has no plan to put up temporary walls with plastic wall sheeting to prevent mold dust and mold toxins from going all over your home.
  • The remediator wears no protective mask or gloves.
  • He has no plan to channel moldy dust from the work area outside through a window or external door.
  • The remediator plans to carry unsealed material through your home.
  • You ask him who will do the “post remediation mold testing” and he looks at you like you have 10 heads.
  • He does not use a HEPA vacuum to clean up after himself.
  • He does not seal off your air conditioning ducts to prevent mold spores and dust from going all over your home during the remediation work.
  • He is foggy from his past jobs. He does not know how to contain mold dust, since he is shoing signs of mold exposure. So do not expect him to know how to prevent the release of moldy dust throughout your home.

5 Levels of Mold Remediation

Thursday, January 31st, 2008

What are the 5 levels of Mold Remediation?

According to Vicki Lankarge in her book “What Every Home Owner Needs to Know About Mold & What to Do About It,” mold remediation can be broken up into 5 levels: level one being the least contamination, level four being the most, and level five HVAC and air conditioning systems.

When dealing with mold contamination in your home it can be difficult to decide when a mold remediator is needed or what you can take care of yourself.

In the following 5 levels, you will have a guideline to go by when removing mold from your home :

5 Levels of Mold Remediation

  • Level I (10 square feet or less)
  • Smaller infestations categorized in level I is mostly found on ceilings or baseboards. Level I mold contamination may be cleaned without hiring a mold remediator, but there are several important safety precautions that you need to know :

    1. Do not attempt cleaning mold if you suffer from asthma, allergies, or immune disorders

    2. Wear gloves, eye protection, and an N95 disposable respirator

    3. Vacate from your work area any infants less than 12 months old, individuals recovering from recent surgery, anyone with a suppressed immune system, or people with chronic lung diseases such as asthma, sever allergies, emphysema, etc.

    4. Contaminated materials that cannot be cleaned should be removed from your home in a sealed plastic bag to prevent an infestation in another part of your home.

    5. Clean your work area when you’re done with a damp cloth or mop.

    6. Make sure all areas are left dry and visibly free of mold contamination.

  • Level II (10-30 square feet)
  • To remove mold from an area category the size of level II (probably one wall panel), the same precautions used in level I should be taken as well as the following :

    1. Moldy materials should be covered with plastic sheets and sealed with tape before any handling or removal of materials. This will contain dust and debris. It may be wise to double wrap in plastic before escorting the moldy material from your home.

    2. WHen the mold removal is finished, vacuum the work area with a HEPA vacujum. Clean the area with a damp cloth or mop.

  • Level III (30-100 square feet)
  • Mold contamination this size (patches of mold on several wall panels), should still be handled with the same precautions as level I and II as well as the following added measures :

    1. Seal ventilation ducts/grills in the work area and areas directly adjacent with plastic sheeting.

    2. Vacate everyone from your work area until work is completed. Further vacate adjacent work areas of any infants less than 12 months old, individuals recovering from recent surgery, anyone with a suppressed immune system, or people with chronic lung diseases such as astma, sever allergies, emphysema, etc.

  • Level IV (greater than 100 square feet)
  • An infestation depending on how much greater than 100 square feet may require the assistance of a mold remediator. If not, the same requirements should be followed as were needed in levels I, II, and III along with the following :

    1. Every worker must be trained in the handling of hazardous materials and equipped with full face respirators with high-efficiency particulate air (HEPA) cartridges, with disposable protective clothing covering both head and shoes.

    2. Make sure workers completely isolate hteir work area from the rest of your home with sheeting sealed with duct tape, including ventilation ducts/grills, fixtures, and any other openings.

    3. Make sure workers set up and use a “decontamination room,” or a chamber taped off with plastic sheeting. The outside of sealed bags containing contaminated material should be wiped down with a damp cloth or HEPA vacuumed in the decontamination chamber prior to their removal.

    4. Air monitoring should be conducted prior to moving back into your home to determine if it is fit to reoccupy.

  • Level V (Air Conditioners and HVAC Systems)
  • If there is a small area of mold growth beneath your air conditioning system it would be safe to apply precautions from levels I and II to remediate the mold contamination. However, all remediation procedures for air conditioning units and HVAC systems should be left to professionals. Procedures for level V remediation for areas larger than 10 square feet are the same for all previous levels with the following precautionary measures added :

    1. Shut down the HVAC system prior to remediation.

    2. Growth-supporting materials that are contaminated, such as the patper on the insulation of interior lined ducts and filters, should be removed and sealed in plastic bags.

    3. A variety of biocides - broad spectrum antimicrobial agents designed to prevent the growth of microorganisms - are recommended by HVAC manufacturers for use with HVAC components, such as cooling coils and condensation pans. HVAC manufacturers should be consulted for the prodcuts they recommend for use in their systems.

5 Simple Tips for Cleaning a Small Mold Infestation

Monday, January 14th, 2008

Mold has been found. Now what?!

Don’t panic! The first thing that needs to be determined is whether or not the infestation is large or small.

Ask yourself, is the area affected with mold small and contained? How much mold can be seen and how much more may be unseen?

If the answer is only small amounts and the area is indeed contained, there are 5 easy tips tips according to Vicki Lankarge in her book “What Every Home Owner Needs to Know About Mold & What to Do About It” that can help you to rid yourself of any further mold problems:

5 Easy Tips for Small Area Mold Remediation

  • Make sure you’re free of allergy symptoms and/or asthma
  • Wear a mask and rubber gloves during clean up
  • Using water and detergent, scrub mold off nonporous surfaces and dry completely. (Perhaps a little bleach wouldn’t hurt as well)
  • Absorbent materials may have to be discarded if they are moldy. It is likely that hidden mold lurks beneath the surface and will grow back and fill in the crevices
  • Dispose of any sponges or rags used to clean the mold (It is best to double bag any mold contaminated items and remove them from the home entirely)

When do I need a mold professional?

If the area is small enough, there won’t be any need for professional help as it can be taken care of with do-it-yourself methods.

Why do it yourself Mold Remediation?

Monday, May 1st, 2006

The killing and removal of mold by professionals is known as mold remediation. This can be timely and therefore a costly solution to your mold problem. For many homeowners, a small mold problem is just as easily taken care of by themselves. There are necessary items needed when attempting a do-it-yourself mold removal, including having the proper equipment and attire. Mold is a serious threat to human health, and even dead mold can cause allergy or asthma problems in those with good health.

By using the proper equipment, and wearing the proper attire, homeowners can make sure they kill and remove the mold in the safest, most effective way. We will be sharing more on Mold Remediation and these tips tomorrow! We’ll see you then.

Dealing With the Threat of Mold After Flooding

Sunday, January 29th, 2006

When Can I Safely Re-Occupy My Home?

This is the most common question often asked after a major calamity. Homes that have sustained any flood damage should expect to have a mold contamination with visible growth, and should not be re-occupied until the necessary mold remediation is performed.

Mold is a now considered as a national health crisis of epidemic proportions due to the health effects from exposure that most commonly occur by inhalation, skin contact, and sometimes, ingestion can be extremely dangerous to anyone, depending on indoor air counts and length of exposure.

It is strongly advised that mold remediation work involving large areas (100 sq ft or 10 ft x 10 ft) should be performed by trained mold remediation experts.

In normal circumstances, areas exceeding 25 to 30 sq ft should also be remediated by trained personnel who can contain the area and remove the mold effectively and safely. By following this suggestion, you don’t risk being exposed to harmful molds and their effects.

Do-It-Yourself Mold Remediation

If you decide to do mold clean up by yourselves, it is strongly advised to use protective equipment and dutifully follow these tips. Use dust masks and gloves, when inspecting areas small that have severe presence of molds.

Always remember to stay for a maximum of 15 minutes only on places were there is severe mold contamination. As much as possible minimize dust release as it also includes mold spores.

If you are trying to clean up an area of at least 100 square feet or a total area of 10 feet by 10 feet, use half-face air purifying respirators with goggles and gloves for safety purposes.

In the event that you are covering an area of 100 square feet it is highly advised to use a full-face air purifying respirator, gloves and disposable cover all. Doing so lowers your chance to exposure to mold spore to zero. But it is still highly suggested that a professional do this.

Mold Remediation in a Two Story Home

If you are doing clean up on a two story house, thoroughly seal-off the second floor by using poly sheeting. Remember to always run a high power exhaust fan in the area where you are working to provide ventilation and prevent possible infiltration of any airborne mold or bacteria into adjoining spaces.

To clean up small debris and dust, use vacuum cleaners with filters. After all these, clean off and disinfect the area with a detergent and bleach solution.

Health and safety advisories to remember when cleaning up after flooding:

  • Be aware of black mold that are growing on sheetrock. There is a possibility that it may be Stachybotrys chartarum. This kind of mold produces a toxin which has been associated with severe health problems in humans.
  • Be vigilant in looking for a whitish or yellowish cotton candy-like mold growth that is observed in many homes.

    This mold growth has been identified in some testing as Fusarium, which like the black mold or Stachybotrys chartarum, also produces a toxin that is associated with adverse health problems in humans.

  • If you smell a gas leak, it is highly advised to call your utility company. Doing so prevents the possibility of fire or explosion that may lead to more damaged property or loss of life.
  • Be aware to stay away from downed power lines and damaged electrical wires. A sudden electrical surge may prove fatal.
  • Usually, mold clean-up activities may result in the release of lead paint dust. It is recommended for households that have children under the age of 7 to have a lead dust wipe post clearance testing.

    Doing this ensures the safety of everyone in your household from possible lead poisoning.

  • There is a probability that the plaster that you may be working on may contain asbestos. More extensive testing is required to really understand and know the scope of this potential problem.

    It is good to know that plaster can be inexpensively tested for asbestos content. Cleaning-up of asbestos-containing plaster surfaces poses a very severe health risk to workers and occupants.

  • In the event that you are using a gas powered generator, place them outside the house. Long term exposure to carbon monoxide will kill anyone.
