If my home has not had a flood or other serious water problem, does that mean it is unlikely to have excessive moisture?

September 22, 2010

Many sources can add moisture to the air in your home. When you go outside on a cold day and can see your breath, you really are seeing moisture coming from your lungs as a normal part of breathing. Breathing and perspiring send moisture from your body into the air of your home. Other sources are:

• Taking a shower or bath
• Boiling water or cooking
• Washing dishes and letting them dry on a drainboard
• Hand washing clothing and hanging it to dry indoors
• Operating certain types of appliances, such as a clothes dryer that is not vented to the outdoors
• Having house plants

Just because the activities listed above can increase moisture in your home does not mean you should stop doing them. You still can cook food, hand wash clothing, take showers and keep house plants.

Simply make sure your normal living patterns do not result in an excessive amount of moisture build-up in your home.

You may want to have your indoor environment assessed by a CIEC Council Certified Indoor Environmental Consultant to help identify any elevations of allergens in your home and identify the cause and origin so you can take the appropriate corrective action.

If you need to have your home inspected for mold make sure your mold inspector is a Florida State Licensed Mold Assessor. To be licensed as a Mold Assessor the State of Florida ensures that your mold assessor is properly, insured, and trained.

The earlier you can detect the growth of mold in your home, the better a chance you have to control it. Early detection and treatment are very important.
If you smell a musty odor in your house, start looking for the source immediately and remove it as soon as you find it. Prevention and early detection may save you from paying much greater cleanup and repair expenses later on. If you own your home, damage from mold and the cost of removing mold might not be covered by your homeowner insurance. (Read your policy or call your insurance agent to find out.)

Before hiring a mold assessor, check with the State of Florida to ensure that your mold assessor is licensed, insured, and trained.


Are there risks associated with having mold in a home?

September 22, 2010

The growth of any type of mold in a home is never acceptable. Your safest and most prudent course of action is to treat all molds with caution and to remove them from your home as soon as possible.

In the spring, some people experience no health effects from the increased amount of pollen in the air, while other people have serious allergic reactions. The same is true with mold spores, both inside and outside a home. Some people experience little or no reaction from high levels of exposure to mold spores. Other people exposed to low levels can have allergic responses, including asthma, stuffy or runny noses, eye irritation, fever, wheezing, inflammation in the lungs, and skin rashes.

These same symptoms can be caused by a variety of allergens. If you experience the symptoms, you should not automatically assume that your home has a mold problem.

You may want to have your indoor environment assessed by a CIEC Council Certified Indoor Environmental Consultant to help identify any elevations of allergens in your home and identify the cause and origin so you can take the appropriate corrective action. If you need to have your home inspected for mold make sure your mold inspector is a Florida State Licensed Mold Assessor. To be licensed as a Mold Assessor the State of Florida ensures that your mold assessor is properly, insured, and trained.

Healthy individuals usually are not vulnerable to health problems from airborne mold exposure. If you have concerns about possible health and safety issues regarding mold, immediately contact a medical professional and/or your local government health authority for guidance.

Remember before hiring an IAQ or mold assessor, check with the State of Florida to ensure that your IAQ mold assessor is licensed, insured, and trained.


How do I know if my home has a mold problem?

September 22, 2010

If mold is growing in your home, you most likely will be able to smell it. Have you ever walked into a room that has a musty or earthy odor? You probably are smelling mold. Sometimes, you can see the mold on the surface of an object. In such cases, the item may be discolored or look as if it has smudges or blotches.

Often, you will not be able to see mold that is causing an odor. The mold could be growing behind walls, underneath carpets, or in other hidden areas. Mold growth is common in areas of a home that are damp or have suffered water damage. You should be especially concerned about the growth of mold if your home has had:

• a flood
• a sewer back-up
• an overflowing toilet
• leaking pipes
• a leaking roof
• leaking windows
• humidifiers
• any other serious water-related problems.

Some of these situations can result in the growth of bacteria, which also can cause musty odors and health problems. If you need to have your home inspected for mold make sure your mold inspector is a Florida State Licensed Mold Assessor. To be licensed as a Mold Assessor the State of Florida ensures that your mold assessor is properly, insured, and trained.

Once materials become wet, mold can begin to grow within 24 to 48 hours. If your home experiences a water-related problem, clean and dry any wet or damp areas as soon as you find them. If you live in a rental property, immediately report water problems to your landlord.
The earlier you can detect the growth of mold in your home, the better a chance you have to control it. Early detection and treatment are very important. If you smell a musty odor in your house, start looking for the source immediately and remove it as soon as you find it. Prevention and early detection may save you from paying much greater cleanup and repair expenses later on. If you own your home, damage from mold and the cost of removing mold might not be covered by your homeowner insurance. (Read your policy or call your insurance agent to find out.)

Before hiring a mold assessor, check with the State of Florida to ensure that your mold assessor is licensed, insured, and trained.


Is it possible to have a home tested for mold?

September 22, 2010

Yes, but health agencies and experts do not recommend testing houses as a first line of detection and prevention.

Mold testing can be expensive and time consuming, and it usually requires special equipment and licensed, insured, and trained mold assessors to obtain reliable results. Once you determine the level of mold in a home, there are no standards for judging if the level could cause problems for the occupants or when a house is clean. But most importantly, you probably will not get the results from your mold test for a couple of days or even a week, during which mold problems could become significantly worse.

If you think you see or smell mold in your home, you should immediately contact a Florida State Licensed Mold Assessor to inspect the affected area and identify the cause and origin to prevent the further damage before you wait for test results.

If you have your home tested, a state licensed mold assessor will have to take an outdoor air sample at the same time as the indoor sample. This will allow the state licensed mold assessor to determine whether the number of spores inside your home is significantly higher than the number outside your home. A higher indoor level could mean that mold is growing indoors. Before hiring a mold assessor, check with the state of Florida to ensure that your mold assessor is licensed, insured, and trained.


Creating a Mold Resistant Home

September 22, 2010

Mold can grow anywhere in your home. We’ve got tips for how to keep it at bay.

There is no such thing as a mold-proof home. Mold spores exist in the air inside our homes, but we can cohabit peacefully as long as those spores don’t find moisture and start growing. If they do, it’s only a matter of time before mold spreads, and once that happens, it can be difficult to nearly impossible to eradicate. There is a silver lining: you can’t eliminate mold, but you can discourage its growth. By taking steps to make your home mold resistant, you’ll avoid the headaches of remediation and repair, as well as the potential health problems mold can cause.

When we say mold is everywhere, it’s no hyperbole. All that mold needs to thrive is moisture, a food source, and warmth. The “food source” can be any number of household items or materials: bedding and draperies, upholstered furniture and carpeting, shower walls and windowsills, wallpaper and ceiling tiles. Before you start to imagine yourself surrounded by angry, hungry mold spores, remember these three basic steps you can take to make your home mold resistant:

1. Prevent moisture.
2. Ventilate.
3. Reduce humidity.

Whether your home is new or old, there are specific steps you can take to make it resistant to mold. Mold affects indoor air quality and can make homes difficult to sell. Follow these mold-prevention tips, and you’ll breathe easier, in more ways than one.

Tips for existing homes
It’s important to remember that no action to make your home mold resistant will be successful if you have a perpetual moisture problem or if mold has already taken hold. Inspect your home thoroughly for problem areas, and keep in mind that mold can hide in places you can’t see, such as inside ductwork or above ceiling tiles. If you suspect you already have a problem, talk to a certified mold inspector to help resolve it before taking these steps to prevent mold growth.

1. Be vigilant of areas of potential moisture and clean up spills and repair leaks immediately, removing water-damaged furniture and fabrics if they cannot be dried out completely.

2. Use dehumidifiers to reduce humidity to 30 to 50 percent and fans to increase air flow in your home, especially if you live in a hot, humid climate.

3. Regularly clean and maintain roof gutters.

4. Regularly clean and maintain AC unit drip pans and drainage lines.

5. Vent moisture-producing appliances, like clothes dryers and stoves, to the outside.

6. Raise the air temperature in your home so moisture doesn’t end up on surfaces as condensation.

7. Open closet doors and doors between rooms and move furniture away from walls and corners to allow air to move freely through your home.

8. Ventilate crawl spaces, and install heavy-duty plastic sheeting over dirt to prevent moisture from coming up from the ground.

9. Add a mold retardant like Taheebo tea to houseplant water to stave off growth in soil and on leaves.

10.Clean and vacuum your home regularly, removing those tasty food sources, like dust particles, that mold feeds on.

Tips for new homes
When starting from scratch, you may be better able to control the mold-resistance of your home. However, since more and more homes are being built with energy efficiency in mind, airflow is more restricted in new homes—and good circulation is crucial for preventing mold. Still, you can have a home that is energy efficient and mold resistant by following a few important tips.

1. Use mold resistant construction products, such as mold resistant drywall, which uses fiberglass instead of paper facing, and drywall tape; paint treated with an EPA-registered fungicide, which discourages growth on painted surfaces; mold resistant insulation, such as Nu-Wool; wood treated with anti-mold chemicals, such as FrameGuard’s; and mold resistant trim, caulk, and sealant.

2. Keep construction materials dry and mold-free before installation, and watch for construction defects that may lead to leaks or water entry.

3. Grade the land down and away from the home’s foundation.

4. Install a strong moisture barrier under concrete slabs and basement floors.

5. Waterproof concrete used for floors, exterior basement walls, and the foundation, such as with a crystalline waterproofing system, which allows concrete to breathe so moisture doesn’t accumulate.

6. Insulate pipes and water-supply lines to prevent cracks and leaks.

7. Install gutters that take water away from the house.

8. Equip the HVAC system with a filter or electronic air cleaner for catching airborne mold spores.

9. Install a programmable dehumidifier to reduce indoor humidity and exhaust fans to prevent moisture.

10. Avoid wall-to-wall carpeting, or install plastic sheeting and subflooring between carpeting and a concrete floor to prevent moisture.
