Mold After A Disaster

Highlights

  • 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.”

Your Kitchen and Mold

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.

Wipe out a bad mold problem

how to clean and remove mold

There isn’t enough elbow grease that could wipe out a bad mold problem.  An urban myth usually states that 1 part bleach and 9 parts water will help remove mold from your home. After adding this solution to a wall, its more probable that you just added water to a mold problem,

How long does is take to clean mold from a wall? Well, if it is done correctly and with the right building materials, once.

Different solutions have been made for mold removal and mold cleaning over the years.  Without a proper understanding of the water (moisture) intrusion, mold will be difficult to remove or clean.

Real Estate Los Angeles, CA

Thinking you might skip the mold inspection before you buy one of the most expensive purchases in your lifetime?  During any real estate transaction, a potential homeowner must decide what type of inspections they should conduct before buying the property.

 


The truth is, a real estate mold inspection will help identify features of your building, undetected by your standard home inspection report.  The above photo is taken from a real estate inspection for mold and water damage.  The Building Inspection Service identified areas of water damaged materials.  After further inspection, these materials had been removed, repaired and painted prior to fun guy’s scheduled building inspection. Our certified mold inspector was able to identify pipes, repaired, but still leaking below the sink! 

 

From the field of view in the picture, you can tell how the area had been painted white within the cabinet in an attempt to hide the visible conditions of water damage and mold growth.  Left Side of the Photo

 

Upon further inspection (lifting the board up) of the area below the kitchen sink, black mold was revealed on the wall below the kitchen cabinet’s (false) flooring. Right side of the Photo

 

Water Damage to the base of the kitchen cabinets and surrounding supports appeared more extensive and began to spread to others areas in the building.  Including a closet and the garage, the walls surrounding the kitchen were also affected by water damage and toxic mold growth conditions.

 

The buyer was aware of the areas that could not be covered up with paint.  Exposed during Fun Guy’s Real Estate Mold Inspection Building Report, the true conditions were reported on the building prior to the real estate purchase.

 

A Building Inspection Check List  includes a Real estate mold inspection.  Fun Guy Inspection & Consulting LLC makes every attempt to identify areas of moisture intrusion, measure the areas of moisture content of the building materials, and identify any unsightly mold growth – Look for FunGuy before You Buy.
