- People with asthma, allergies, or other breathing conditions may be more sensitive to mold.
- If you or your family members have health problems after exposure to mold, contact your doctor or other health care provider.
- Controlling moisture in your home is the most critical factor for preventing mold growth.
- If you plan to be inside the building for a while or you plan to clean up mold, you should buy N95 masks (or a respirator with a higher protection level) at your local home supply store and wear one while in the building. Make certain that you follow instructions on the package for fitting the mask tightly to your face. Even if you go back into the building for a short time and are not cleaning up mold, you need to wear an N95 mask.
After natural disasters such as hurricanes, tornadoes, and floods, excess moisture and standing water contribute to the growth of mold in homes and other buildings. When returning to a home that has been flooded, be aware that mold may be present and may be a health risk for your family.
People at Greatest Risk from Mold
- People with asthma, allergies, or other breathing conditions may be more sensitive to mold.
- People with immune suppression (such as people with HIV infection, cancer patients taking chemotherapy, and people who have received an organ transplant) are more susceptible to mold infections. People with a weakened immune system, especially people receiving treatment for cancer, people who have had an organ or stem cell transplant, and people taking medicines that suppress the immune system, should avoid cleaning up mold. Children should not take part in disaster cleanup work.
Possible Health Effects of Mold Exposure
People who are sensitive to mold may experience stuffy nose, irritated eyes, wheezing, or skin irritation. People allergic to mold may have difficulty in breathing and shortness of breath. People with weakened immune systems and with chronic lung diseases, such as obstructive lung disease, may develop mold infections in their lungs. If you or your family members have health problems after exposure to mold, contact your doctor or other health care provider.
Safely Preventing Mold Growth
Clean up and dry out the building quickly (within 24 to 48 hours). Open doors and windows. Use fans to dry out the building. Position fans to blow air out doors or windows.
See the fact sheet for drying out your house, Reentering Your Flooded Home and the Homeowner’s and Renter’s Guide to Mold Cleanup After Disasters.
- When in doubt, take it out! Remove all porous items that have been wet for more than 48 hours and that cannot be thoroughly cleaned and dried. These items can remain a source of mold growth and should be removed from the home. Porous, noncleanable items include carpeting and carpet padding, upholstery, wallpaper, drywall, floor and ceiling tiles, insulation material, some clothing, leather, paper, wood, and food. Removal and cleaning are important because even dead mold may cause allergic reactions in some people.
- To prevent mold growth, clean wet items and surfaces with detergent and water.
- Homeowners may want to temporarily store items outside of the home until insurance claims can be filed. See recommendations by the Federal Emergency Management Agency (FEMA).
- If you wish to disinfect, refer to the U.S. Environmental Protection Agency (EPA) document, A Brief Guide to Mold and Moisture in Your Home[1.4 MB, 20 Pages].
If there is mold growth in your home, you should clean up the mold and fix any water problem, such as leaks in roofs, walls, or plumbing. Controlling moisture in your home is the most critical factor for preventing mold growth.
To remove mold growth from hard surfaces use commercial products, soap and water, or a bleach solution of no more than 1 cup of household laundry bleach in 1 gallon of water. Follow the manufacturers’ instructions for use (see product label). Use a stiff brush on rough surface materials such as concrete.
If you choose to use bleach to remove mold:
- Never mix bleach with ammonia or other household cleaners. Mixing bleach with ammonia or other cleaning products will produce dangerous, toxic fumes
- Open windows and doors to provide fresh air. Use fans to dry out the building. Position fans to blow air out doors or windows.
- Wear non-porous gloves and protective eye wear.
- If the area to be cleaned is more than 10 square feet, consult the U.S. Environmental Protection Agency (EPA) guide titled Mold Remediation in Schools and Commercial Buildings. Also available is A Brief Guide to Mold, Moisture, and Your Home.[1.4 MB, 20 Pages]
- Always follow the manufacturer’s instructions when using bleach or any other cleaning product.
- For more information on personal safety while cleaning up after a natural disaster, see Response Worker Health and Safety.
If you plan to be inside the building for a while or you plan to clean up mold, you should buy N95 masks (or respirators with a higher protection level) at your local home supply store and wear one while in the building. Make certain that you follow instructions on the package for fitting the mask tightly to your face. Even if you go back into the building for a short time and are not cleaning up mold, you still need to wear an N95 mask.”

Mold inspections for black mold are like any other inspection. Mold Inspectors will search for water damaged materials and determine if the materials are wet. Further sampling is required, in each instance, to determine if the dark colored mold is indeed black mold or stachybotrys.
Kitchen Mold Removal
Are you concerned that black mold could be lurking in your kitchen, perhaps hiding in the cupboards? Not only is it unattractive, it can also cause respiratory problems for your family. The following guide can help you locate, prevent and destroy any black mold that has taken up residence in your kitchen.
Where to find black mold in the kitchen?
Black mold tends to grow in dark, damp areas, which means it could be festering in a kitchen cabinet or cupboard for a long time before you uncover it. For this reason, it’s vital that you identify the areas in your kitchen that are going to be most prone to mold growth. This will give you the necessary knowledge so that you can find the problem before it gets too bad. Places to check include the following:
- Underneath the kitchen sink. Check the cabinet bottom and the back wall where the sink pipes enter for dampness or past signs of water damage, such as bubbling or peeling surfaces. Even if black mold isn’t visible, it could be growing on the underside of the sink cabinet or behind the wallboard.
- Under the refrigerator. A leak from a water line to the icemaker or simple condensation collection underneath the fridge could create the optimum environment for fungal growth. If your kitchen flooring looks like it has suffered water damage or if there is standing water and mildew present, black mold could also be growing under the floorboards. Also, check any cupboards near the fridge to make sure there is no moisture damage.
- Cabinets above or next to wall mounted microwaves or oven hoods. Another common trouble spot is behind the cabinets that border microwaves and hoods. This is because moisture and condensation from cooking can accumulate in these cupboard areas, especially if ventilation is insufficient.
Kitchen mold prevention
Since prevention is key to black mold management in the home, now that you know your kitchen’s trouble spots you are better able to stop it from growing in the first place.
Begin by checking underneath the sink on a regular basis and fixing leaks immediately. Keep the sink cupboard area clean and neat so you can empty it out for a quick leak check regularly. If you are like many people and use this cupboard area for cleaning supplies, place the supplies in a handled carrier so you can quickly pull everything out. A good time to check is after you have been using the sink, such as after dishwashing. If there is a leak, it is likely going to be damp if you just drained the sink.
As for the fridge, it’s good practice to pull it out and dust the rear coils every one to two months, anyway. Simply pencil this chore into your home maintenance calendar. You can then use this opportunity to check beneath the fridge for leaks and to make sure water lines are attached and not leaking.
Finally, inspect the area around and under the cabinets, microwave, and hood after you use the oven or microwave. If you find a lot of moisture or condensation, chances are that you need to add a stronger fan or better ventilation to the kitchen.
Kitchen mold removal
Black mold can be tenacious when it comes to removal. Although you can often remove the visible black mold by yourself, there is likely hidden mold that you cannot find for removal as easily. The basic removal process is as follows:
Step 1: Testing Testing is done if there is signs of moisture but no obvious visual signs of fungal growth. Testing may also be done if there is light visible growth, since the remediation firm will need to determine the extent of the growth.
Step 2: Seal the infested area The home is sealed. This means that the area that has mold, in this case the kitchen, is sealed off from the rest of the house so that black mold removal doesn’t send spores into other areas.
Step 3: Identification and replacement The cause of moisture is identified and fixed. Otherwise, the mold will simply return if there is still a moisture source. This may mean the removal and replacement of cabinets and wallboard so they cleaning can occur under them.
Last step: Removal and cleaning The actual removal and remediation begins. The crew will use a disinfecting and cleaning solution that removes and kills the fungus. Stains from the black mold may be present on cabinets, but these can usually be painted over and repaired.
Summertime traditionally brings family trips, school vacations, as well as plenty of hot uncomfortable weather. Those sunny days, however, often come with high humidity and afternoon thundershowers — ideal conditions for annoying and potentially toxic mold.
It’s a pervasive menace that is poised each summer to grow and thrive in your house. Left unattended, fast-growing mold can cause damage that will cost in the thousands of dollars to eradicate or, worse, pose a dangerous threat to the health of your entire family.
“No one knows how many homes have mold behind the walls, but the best estimate is about 70 percent,” said Richard E. Gots, a doctor and founder of the International Center for Toxicology and Medicine, a biomedical consulting firm.
Gots’s estimate refers to mold that is at an “elevated level” and therefore should be addressed if the conditions exist for the mold to take hold and grow.
The Environmental Protection Agency sets levels for acceptable radon levels as well as a threshold for lead in the house or water supply, and states regulate termite inspections and control compliance. Yet there are no federal or state regulations that dictate a safe level of mold for a residential property.
D.C. Council member Mary M. Cheh (D-Ward 3) has been campaigning for several years to pass legislation that would require residential property owners, including landlords, to disclose the presence of mold in their apartment, condo or house. This legislation is still pending.
According to the District’s housing code, the Department of Consumer Regulatory Affairs (DCRA) inspectors cannot cite a homeowner for mold because the city considers mold to be “an environmental problem,” rather than a housing or safety issue. Mold, of course, is notoriously difficult to detect, and what may look like dangerous mold can only be legitimately determined under a microscope by a competent inspector or lab. Additionally, most homeowner insurance policies will not cover damage from mold — they consider it a “preventable” condition.
In reality, mold is a fungus that can grow anywhere moisture is present. Mold spores thrive in warm temperatures (77 to 86 degree Fahrenheit) and wherever there are damp conditions. Mold spores are in the air we breathe, and they can grow on any surface. In a house, mold can be found in ceilings and walls, under sinks, in drywall, hidden behind wallpaper or baseboards, in the ductwork or even on furniture and clothes. It can also grow outdoors under wood piles or mulch, gutters or abandoned trash.
Mold in a house can lay dormant until it gets the needed heat and humidity to grow and multiply. Additionally, it needs a food source, such as dust, dirt or some other organic debris.
While not everyone will react to this growth in the same way, those sensitive to allergic or toxic mold can develop alarming symptoms upon merely entering a contaminated room. The result can be a serious — even life-threatening — illness if not treated in time.
If you suspect that you’ve been exposed to mold — or begin to experience dizziness, fatigue, nausea, shortness of breath or other symptoms of illness — contact a mold specialist and have your property inspected as soon as possible. Licensed professionals will test the air quality of your house and take samples of the visual mold, which will be sent to a qualified lab for evaluation.
The EPA provides helpful information in its publication “A Brief Guide to Mold, Moisture, and Your Home” at www.epa.gov/mold/moldguide.html . And the Centers for Disease Control and Prevention focuses on the health hazards of mold exposure and provides recommendations for removing mold exposure at www.cdc.gov/mold/dampness_facts.htm#note .
In addition to the traditional methods for eradicating mold (such as using chemicals or chlorine bleach and physically removing infected surfaces), there is a new, enzyme-based alternative. Previously used as a protective spray for fruits and vegetables, it is now available for home use.
Jenn Sherwood, manager of Green Home Solutions of Maryland, says that the enzyme spray is a cost-effective, time-saving and environmentally responsible way for homeowners to eradicate mold. The process uses a “fogger,” which emits a fine spray that is able to penetrate most porous surfaces (such as drywall) or even non-visible areas — behind walls or inside insulation. This method of eradicating mold often eliminates the need to remove and replace the existing material.
The EPA regards this spray as nontoxic to humans or pets and harmless to both surfaces and belongings in the home. The enzyme works by creating a bond with the mold spore, and then breaking it down from the inside. As a result, the mold is chemically altered into a particle that is no longer allergenic, toxigenic, or able to reproduce other spores. This treatment can cost from one-third to one-tenth less than the cost of traditional methods.
Given that your insurance company may not cover mold damage, it’s important to take immediate action.
Here are three easy steps to help prevent mold when you go on vacation:
●Check for areas where water could accumulate — such as around windows, doors, bathroom leaks, kitchen sinks and washing machines.
●Clean surfaces of oil, soap, dust and dirt. Those materials are a feeding ground for mold when moisture is present.
●Set the temperature inside the house in the low 70s, if possible. If you suspect humidity, set a dehumidifier to keep the moisture level below 60 percent. In your closet, place a hanging moisture absorber (such as Damp Rid) that will trap excess humidity and eliminate musty odors.
Sandy Gadow, a freelance writer and author of “The Complete Guide to Your Real Estate Closing,”
In 2000, a new “toxic mold” panic swept the country, and after 16 years of untold lawsuits and billions of dollars spent, major myths still plague and unnecessarily panic association boards, managers and homeowners. The myths all too often cause exaggerated repairs, unduly frightened residents, and conflict. In this and the next column, I will address thirteen pervasive toxic mold myths.
1. Mold is new. Mold, one of the earliest and simplest life forms, has existed for thousands of years. Almost 100 years ago, mold was the basis of the discovery of penicillin. Mold is ever-present, as is dust or pollen.
2. The scientific and medical communities confirm mold’s many dangers. In 2004, the National Institute of Medicine published its comprehensive study on indoor mold exposure, called “Damp Indoor Spaces and Health.” A central finding was: “Scientific evidence links mold … in homes and buildings to asthma symptoms in some people with the chronic disorder, as well as to coughing, wheezing, and upper respiratory tract symptoms in otherwise healthy people… However, the available evidence does not support an association between … mold and the wide range of other health complaints that have been ascribed.”
That sounds like mold is as dangerous as dust or pollen to people with severe asthma. The announcement containing this finding is easily located by a web search, but it did not receive much press play – stories of frightened people living in tents are more interesting.
3. One must determine the kind of mold present. Mold consultants and plaintiff attorneys often describe some molds as worse than others. The most famous mold is stachybotrys chartarum, a mold producing infinitesimal quantities of a substance similar to botulism poison. However, the amount is so small they call it a “mycotoxin.” It sounds frightening, but the scientific community long ago debunked the myth that this or any mold was somehow poisonous to breathe. For example, read the National Institute of Health Fact Sheet on Mold, found at www.niehs.nih.gov.
4. California is protected by the Toxic Mold Protection Act of 2001. The act instructed the Department of Public Health to develop permissible exposure limits of the various mold strains. However, in 2005, and again in 2008, the DPH reported the task could not be completed with the scientific information available. Consequently, there is presently no official standard as to how many mold spores of any given variety are “unhealthy.”
5. Always start with a mold test. The Environmental Protection Agency recommends against mold testing. There is no standard as to how many mold spores are “unhealthy,” and indoor air sampling tests are extremely vulnerable to events in the home, which can change the results. A recent shower, window opening or carpet cleaning are some of the many factors that can completely change test outcomes.
Mold tests, to put it bluntly, primarily frighten the occupants and create a “need” for the expense of a mold consultant, and a second test after the area is cleaned. Since the health authorities have not confirmed any particular strain is more dangerous, and since there is no official standard as to how many airborne spores are unhealthy, there is rarely a good reason to spend the money on such a test.
