Mold After a Flood
Homeowner’s and Renter’s Guide to Mold Cleanup After Disasters
Homeowner's and Renter's Guide to Asbestos Cleanup After Disasters
What to Know About Mold After a Flood
Mold is a general term used to describe certain types of fungi. Wherever there is moisture, mold can grow. It can grow on food, building materials, upholstery, clothes and other surfaces. There are many different types of molds that vary in color and appearance. No species of mold is named “black mold.” Exposure to mold can impact your health.
Assume there is mold in your home or building if it has been flooded and it has not been dried out within 24 to 48 hours.
Testing for mold
Testing for mold is not necessary or recommended.
This is because:
Understanding the results can be difficult because there are no standards
to compare the results to.
Test results cannot be used to say a building is “safe” or “unsafe.”
No matter how much or what kind of mold is in your home or building, the action steps to fix the problem are the same: remove the moldy items, dry out the space, and fix the source of water intrusion.
Protecting yourself from mold
Wear protective clothing, such as pants and long sleeves, waterproof work boots, rubber gloves, goggles, and a disposable N95 respirator.
Do not let children, people with breathing problems and people with weakened immune systems help clean up after a flood.
Use portable air cleaners with HEPA (high-efficiency particulate air) filters.
See the
EPA’s Guide to Air Cleaners in the Home
.
Minimize spreading dust, debris and mold to other areas of your home or building by using plastic sheeting to separate the moldy area.
Learn more about containment from the EPA
.
Have your heating, ventilating, and air-conditioning (HVAC) system checked and cleaned by a professional who is experienced in mold clean-up before you turn it on.
Fixing a mold problem
To fix a mold problem, remove moldy items and completely dry out your home or building. Mold will come back if your home or building is not completely dry.
Dry your home or building by:
Opening all doors and windows including interior and attic access to allow air flow.
Using dehumidifiers and fans (when the electricity is safe) placed at a window or door to blow the air out rather than into your home to avoid spreading mold.
Remove mold by following these steps:
Clean moldy items that do not absorb water (like glass, plastic, marble, granite, ceramic tile, metal) by using soap and water. Disinfect any surfaces that came in contact with floodwater after cleaning them.
Throw away and replace materials that easily absorb water (cushions, mattresses, drywall, carpet, insulation, and ceiling tiles). If your child's car seat was exposed to floodwater and cannot be machine washed, throw it away. Never launder car seat harnesses.
Wash clothes and other fabrics, including clothes worn during the cleanup, in hot water and detergent. Keep them separate from uncontaminated items.
Vacuum with a HEPA vacuum.
Hiring a contractor
There are no federal or Vermont certifications or licenses for mold clean up. If you hire someone to clean up mold in your home or building and they will be using chemicals, they may need to be certified by the
Agency of Agriculture, Food and Markets
. Many of the chemicals used to clean up mold are pesticides and users must be trained to use them. You can email
[email protected]
with questions about products used to control mold.
If mold is covering more than 10 square feet (roughly 3 feet by 3 feet), you may want to hire a contractor that specializes in mold cleanup. A contractor is generally not needed for a small mold problem of less than 10 square feet.
Ask the contractor to follow cleanup guidance from organizations like the
Environmental Protection Agency
or the
Institute of Inspection, Cleaning and Restoration Certification (IICRC)
.
As with any contractor, get references to assess the contractor’s experience, past work success, and if other clients liked their work.
Information for renters and employees
If you are a renter or employee, talk with your landlord or employer about mold problems. If the problem is serious and conditions persist, renters may want to
file a complaint with the Division of Fire Safety
, and employees may wish to contact the Vermont Occupational Safety and Health Administration (VOSHA).
Frequently asked questions about mold
Should I test for mold if my home or building was flooded?
No, testing for mold is not necessary or recommended. If your home or building has been flooded and you were not able to dry it out within 24 to 48 hours, assume you have mold growth.
Why should I use soap and water?
Soap and water are safe and effective. Using a disinfectant to kill mold is not usually recommended. Dead mold can still cause health effects in some people. Mold ultimately needs to be physically removed. First, wipe surfaces with soap and water to remove mold. Then, vacuum surfaces with a HEPA vacuum.
When should I disinfect surfaces in my home or building?
Using a disinfectant to kill mold is not usually recommended. However, you need to disinfect surfaces that have come in contact with floodwater. You may also need to disinfect porous foundation materials or foundation materials with cracks and crevices (for example, stone, block wall or concrete) to kill mold you cannot remove by cleaning alone. First, clean surfaces with soap and water. Then disinfect them by following the steps in the next question.
If I need to disinfect surfaces, what type of disinfectant should I use?
When possible, choose a disinfectant that uses a safer active ingredient – like hydrogen peroxide, citric acid, ethanol or lactic acid – rather than using bleach. Make sure to follow all the instructions on the product label and wear protective clothing, including disposable N-95 masks, gloves and goggles.
Find out more about safer disinfectants
.
How can I prevent future mold growth if my basement is often wet?
Preventing water and moisture problems in your home or building is the key to preventing future mold growth. In humid basements, running a dehumidifier set between 40 and 60% relative humidity can help. Basements that are very damp or wet may need a water or drainage system installed or changes may need to be made outside to direct water away from the home or building's foundation. Talk to a professional to discuss the best system for your home or building.

Frequently Asked Questions
Is my drinking water (from a well or spring) contaminated by the flooding?
If you are on a private well or spring and floodwater has reached your well or spring,
assume your water is contaminated
. Do not use the water from your well or spring until you have it tested and results indicate that the water is free of contamination.
Kits can be purchased online
. If you already received a free initial test kit and need to retest after treating your well/spring, you can get a free retest online or
from your local health office
. Learn more about what to do if you
have a private well or spring.
Get water from a known safe source (for example, from a public building served by town or city water that is not on a boil water notice or from friends or family not impacted by the flood), or use bottled water until you have your water tested.
If you are on public water (for example, you pay a water bill), check the
boil water and do not drink list
to stay informed about your water quality.
Learn more about drinking water testing
When is it safe to swim in lakes, rivers and swimming holes again?
The Health Department advises to
stay out of rivers and streams until the water is clear and calm
and to use extra caution when swimming in lakes and ponds that have been affected by flooding.
Heavy rainfalls can create potentially dangerous conditions in swim holes, streams, rivers, and waterfalls. These conditions of high water or strong undercurrents can linger several days after a storm, so be sure to assess the water depth and flow before swimming or boating.
Generally, you should stay out of any body of water for
at least 48 hours following a significant rain event
. If there is major flooding, it will take extra time for waterbodies to recover. This is because flooding can cause combined sewer overflows (raw sewage dumped into waterbodies) as well as extra debris and fuel and other chemicals to flow into waterbodies.
Rivers, ponds, lakes and streams are always susceptible to disease-causing microorganisms and chemicals from stormwater runoff and are especially susceptible after the widespread rainfall and flooding. Swimming in these waters may result in health effects such as minor skin rashes, sore throats, diarrhea or more serious problems.
Additionally, after major flooding, extra nutrients from the floodwater may cause cyanobacteria blooms a few weeks after. Be sure to
watch for cyanobacteria
.
Learn more about
recreational water safety after a flood
.
What do I need to know about mold in my home or business?
If your home or building has been flooded and you were not able to dry it out within 24 to 48 hours, assume you have mold growth. Testing for mold is not necessary or recommended.
To fix a mold problem, you must completely dry out your home or building first. Mold will come back if your home or building is not completely dry. Learn more about
what to do about mold after a flood
.
Can I eat vegetables from my garden if it was flooded?
Do not eat vegetables or fruit that have come into direct contact with floodwater. The Vermont Agency of Agriculture, Food & Markets recommends waiting at least 30 days before replanting to allow the soil to dry out and allow for the natural die-off of any disease-causing bacteria or microorganisms that may have soaked into the soil from the floodwater.
How can I use baby formula safely after a flood?
For families who have been affected by flooding and use formula, ready-to-feed infant formula is a safe option if you have refrigeration.
After a flood, tap water may not be safe to mix with powdered infant formula. Ready-to-feed infant formula is a sterile liquid infant formula that is ready to feed without adding water.
There may be times when powdered infant formula is the only option. If you need to use powdered infant formula when tap water is unsafe to drink, learn more about
how to prepare and store it safely and correctly
.

Throw away and replace materials that easily absorb water (cushions, mattresses, drywall, carpet, insulation, and ceiling tiles). If your child's car seat was exposed to floodwater and cannot be machine washed, throw it away. Never launder car seat harnesses.
Wash clothes and other fabrics, including clothes worn during the cleanup, in hot water and detergent. Keep them separate from uncontaminated items.
Vacuum with a HEPA vacuum.
Hiring a contractor
There are no federal or Vermont certifications or licenses for mold clean up. If you hire someone to clean up mold in your home or building and they will be using chemicals, they may need to be certified by the
Agency of Agriculture, Food and Markets
. Many of the chemicals used to clean up mold are pesticides and users must be trained to use them. You can email
[email protected]
with questions about products used to control mold.
If mold is covering more than 10 square feet (roughly 3 feet by 3 feet), you may want to hire a contractor that specializes in mold cleanup. A contractor is generally not needed for a small mold problem of less than 10 square feet.
Ask the contractor to follow cleanup guidance from organizations like the
Environmental Protection Agency
or the
Institute of Inspection, Cleaning and Restoration Certification (IICRC)
.
As with any contractor, get references to assess the contractor’s experience, past work success, and if other clients liked their work.
Information for renters and employees
If you are a renter or employee, talk with your landlord or employer about mold problems. If the problem is serious and conditions persist, renters may want to
file a complaint with the Division of Fire Safety
, and employees may wish to contact the Vermont Occupational Safety and Health Administration (VOSHA).
Frequently asked questions about mold
Should I test for mold if my home or building was flooded?
No, testing for mold is not necessary or recommended. If your home or building has been flooded and you were not able to dry it out within 24 to 48 hours, assume you have mold growth.
Why should I use soap and water?
Soap and water are safe and effective. Using a disinfectant to kill mold is not usually recommended. Dead mold can still cause health effects in some people. Mold ultimately needs to be physically removed. First, wipe surfaces with soap and water to remove mold. Then, vacuum surfaces with a HEPA vacuum.
When should I disinfect surfaces in my home or building?
Using a disinfectant to kill mold is not usually recommended. However, you need to disinfect surfaces that have come in contact with floodwater. You may also need to disinfect porous foundation materials or foundation materials with cracks and crevices (for example, stone, block wall or concrete) to kill mold you cannot remove by cleaning alone. First, clean surfaces with soap and water. Then disinfect them by following the steps in the next question.
If I need to disinfect surfaces, what type of disinfectant should I use?
When possible, choose a disinfectant that uses a safer active ingredient – like hydrogen peroxide, citric acid, ethanol or lactic acid – rather than using bleach. Make sure to follow all the instructions on the product label and wear protective clothing, including disposable N-95 masks, gloves and goggles.

.
How can I prevent future mold growth if my basement is often wet?
Preventing water and moisture problems in your home or building is the key to preventing future mold growth. In humid basements, running a dehumidifier set between 40 and 60% relative humidity can help. Basements that are very damp or wet may need a water or drainage system installed or changes may need to be made outside to direct water away from the home or building's foundation. Talk to a professional to discuss the best system for your home or building.

Frequently Asked Questions
Is my drinking water (from a well or spring) contaminated by the flooding?
If you are on a private well or spring and floodwater has reached your well or spring,
assume your water is contaminated
. Do not use the water from your well or spring until you have it tested and results indicate that the water is free of contamination.
Kits can be purchased online
. If you already received a free initial test kit and need to retest after treating your well/spring, you can get a free retest online or
from your local health office
. Learn more about what to do if you
have a private well or spring.
Get water from a known safe source (for example, from a public building served by town or city water that is not on a boil water notice or from friends or family not impacted by the flood), or use bottled water until you have your water tested.
If you are on public water (for example, you pay a water bill), check the
boil water and do not drink list
to stay informed about your water quality.
Learn more about drinking water testing
When is it safe to swim in lakes, rivers and swimming holes again?
The Health Department advises to
stay out of rivers and streams until the water is clear and calm
and to use extra caution when swimming in lakes and ponds that have been affected by flooding.
Heavy rainfalls can create potentially dangerous conditions in swim holes, streams, rivers, and waterfalls. These conditions of high water or strong undercurrents can linger several days after a storm, so be sure to assess the water depth and flow before swimming or boating.
Generally, you should stay out of any body of water for
at least 48 hours following a significant rain event
. If there is major flooding, it will take extra time for waterbodies to recover. This is because flooding can cause combined sewer overflows (raw sewage dumped into waterbodies) as well as extra debris and fuel and other chemicals to flow into waterbodies.
Rivers, ponds, lakes and streams are always susceptible to disease-causing microorganisms and chemicals from stormwater runoff and are especially susceptible after the widespread rainfall and flooding. Swimming in these waters may result in health effects such as minor skin rashes, sore throats, diarrhea or more serious problems.
Additionally, after major flooding, extra nutrients from the floodwater may cause cyanobacteria blooms a few weeks after. Be sure to
watch for cyanobacteria
.

What do I need to know about mold in my home or business?
If your home or building has been flooded and you were not able to dry it out within 24 to 48 hours, assume you have mold growth. Testing for mold is not necessary or recommended.
To fix a mold problem, you must completely dry out your home or building first. Mold will come back if your home or building is not completely dry. Learn more about
what to do about mold after a flood
.
Can I eat vegetables from my garden if it was flooded?
Do not eat vegetables or fruit that have come into direct contact with floodwater. The Vermont Agency of Agriculture, Food & Markets recommends waiting at least 30 days before replanting to allow the soil to dry out and allow for the natural die-off of any disease-causing bacteria or microorganisms that may have soaked into the soil from the floodwater.
How can I use baby formula safely after a flood?
For families who have been affected by flooding and use formula, ready-to-feed infant formula is a safe option if you have refrigeration.
After a flood, tap water may not be safe to mix with powdered infant formula. Ready-to-feed infant formula is a sterile liquid infant formula that is ready to feed without adding water.
There may be times when powdered infant formula is the only option. If you need to use powdered infant formula when tap water is unsafe to drink, learn more about
how to prepare and store it safely and correctly
.
