• Before You Move

     

    Protect yourself by hiring a Licensed Home Inspector to inspect your potential new home. If you identify problems, have the landlord or seller correct them before you move in, or even consider moving elsewhere.

    • Have professionals check the heating and cooling system, including humidifiers and vents. Have duct lining and insulation checked for growth.
    • Check for exhaust fans in bathrooms and kitchens. If there are no vents, do the kitchen and bathrooms have at least one window in each room? Does the stovetop have a hood vented outside? Does the clothes dryer vent outside? Do all vents exhaust to the outside of the building, and not in attics or crawlspaces?
    • Look for obvious mold growth throughout the house, including attics, basements and crawlspaces, and around the foundation outside. See if there are many plants close to the house, particularly if they are damp and rotting. They are a potential source of biological pollutants. Downspouts from roof gutters should route water away from the building.
    • Look for stains on the walls, floor or carpet (including any carpet over concrete floors) as evidence of previous flooding or moisture problems. Is there moisture on windows and surfaces? Are there signs of leaks or seepage in the basement?
    • Look for rotted building materials, which may suggest moisture or water damage.
    • If you or anyone else in the family has a pet allergy, ask if any pets have lived in the home.
    • Examine the design of the building. Remember that in cold climates, overhanging areas, rooms over unheated garages, and closets on outside walls may be prone to problems with biological pollutants.
    • Look for signs of cockroaches. (Carefully read instructions for use and any cautionary labeling on cleaning products before beginning cleaning procedures.)
    • Do not mix any chemical products. Especially, never mix cleaners containing bleach with any product (such as ammonia) which does not have instructions for such mixing. When chemicals are combined, a dangerous gas can sometimes be formed.
    • Household chemicals may cause burning or irritation to skin and eyes.
    • Household chemicals may be harmful if swallowed or inhaled.
    • Avoid contact with skin, eyes, mucous membranes, and clothing.
    • Avoid breathing vapor. Open all windows and doors, and use an exhaust fan that sends the air outside.
    • Keep household chemicals out of reach of children.
    • Rinse treated surface areas well to remove all traces of chemicals.

    Correcting Water Damage

    What if damage is already done? Follow these guidelines for correcting water damage:

    • Throw out mattresses, wicker furniture, straw baskets and the like that have been water damaged or contain mold. These cannot be recovered.
    • Discard any water-damaged furnishings, such as carpets, drapes, stuffed toys, upholstered furniture, and ceiling tiles, unless they can be recovered by steam cleaning or hot-water washing and thorough drying.
    • Remove and replace wet insulation to prevent conditions where biological pollutants can grow.

    Reducing Exposure to Biological Contaminants

    General good housekeeping, and maintenance of heating and air-conditioning equipment, are very important. Adequate ventilation and good air distribution also help. The key to mold control is moisture control. If mold is a problem, clean up the mold and get rid of excess water and moisture. Maintaining the relative humidity between 30% to 60% will help control mold, dust mites and cockroaches. Employ integrated pest management to control insect and animal allergens. Cooling-tower treatment procedures exist to reduce levels of Legionella and other organisms.

    Install and use exhaust fans that are vented to the outdoors in kitchens and bathrooms, and vent clothes dryers outdoors. These actions can eliminate much of the moisture that builds up from everyday activities. There are exhaust fans on the market that produce little noise, an important consideration for some people. Another benefit to using kitchen and bathroom exhaust fans is that they can reduce levels of organic pollutants that vaporize from hot water used in showers and dishwashers. Ventilate the attic and crawlspaces to prevent moisture build-up. Keeping humidity levels in these areas below 50% can prevent water condensation on building materials.

    If using cool mist or ultrasonic humidifiers, clean appliances according to the manufacturer’s instructions and refill with fresh water daily. Because these humidifiers can become breeding grounds for biological contaminants, they have the potential for causing diseases such as hypersensitivity pneumonitis and humidifier fever. Evaporation trays in air conditioners, dehumidifiers, and refrigerators should also be cleaned frequently.

    Thoroughly clean and dry water-damaged carpets and building materials (within 24 hours, if possible), or consider removal and replacement. Water-damaged carpets and building materials can harbor mold and bacteria. It is very difficult to completely rid such materials of biological contaminants.

    Keep the house clean. House dust mites, pollens, animal dander, and other allergy-causing agents can be reduced, although not eliminated, through regular cleaning. People who are allergic to these pollutants should use allergen-proof mattress encasements, wash bedding in hot water (130° F), and avoid room furnishings that accumulate dust, especially if they cannot be washed in hot water. Allergic individuals should also leave the house while it is being vacuumed because vacuuming can actually increase airborne levels of mite allergens and other biological contaminants. Using central vacuum systems that are vented to the outdoors, or vacuums with high efficiency filters may also be of help.

    Take steps to minimize biological pollutants in basements. Clean and disinfect the basement floor drain regularly. Do not finish a basement below ground level unless all water leaks are patched and outdoor ventilation and adequate heat to prevent condensation are provided. Operate a dehumidifier in the basement, if needed, to keep relative humidity levels between 30% to 50%.
