Too How To Stop Mold In A Basement Closet much moisture in a home can lead to mold, mildew, and other biological growth. This in turn can lead to a variety of health effects ranging from more common allergic reactions, to http://www.epa.gov/asthma/index.html asthma attacks, and hypersensitivity pneumonitits, How To Stop Mold In A Basement Closet for example.
 
Excess moisture can be in the form of high relative humidity How To Stop Mold In A Basement Closet including humidity generated by people and their activities such as showers, cooking, or drying clothes. Water How To Stop Mold In A Basement Closet can also come from plumbing leaks, wet boots, How To Stop Mold In A Basement Closet or splashing around sinks. Moisture can travel with infiltrating outdoor air (or exfiltrating indoor air) through the building shell, including the foundation. In addition to health problems, How To Stop Mold In A Basement Closet high relative humidity or water that enters building cavities that is not allowed to dry quickly can lead to How To Stop Mold In A Basement Closet problems such as rot, structural damage, and premature paint failure.
 
 Methods to control moisture include building an energy-efficient home with proper air-sealing, proper use of vapor barriers and vapor diffusion How To Stop Mold In A Basement Closet strategies. The entire building envelope, How To Stop Mold In A Basement Closet from the foundation to the roof, should be designed to not only prevent moisture entry, but also to allow any moisture which does enter a means to escape. As mentioned above, people and their activities in a How To Stop Mold In A Basement Closet home are big sources of moisture; thus proper ventilation is also important in order to maintain indoor humidity levels within an acceptable range. How To Stop Mold In A Basement Closet Moisture Control Techniques
 
1. Manage water outside the foundation walls. The ground How To Stop Mold In A Basement Closet around the home's foundation should be graded to slope down and away from the house at a rate of 1/2" to 1" per How To Stop Mold In A Basement Closet linear foot to drain surface water away from the house. Water from down spouts should be directed away from the house, discharging at least a few feet from the foundation. How To Stop Mold In A Basement Closet Test any underground drains with a hose to make sure they are working properly. Drains that are not working should be repaired or replaced with an elbow discharge described above. Be sure that driveways, sidewalks, and patios slope down and away from foundation walls at 1/4" per linear foot. In extreme cases, you may have to dig out How To Stop Mold In A Basement Closet around the foundation and replace the fill with an exterior drain tile and with a good draining material How To Stop Mold In A Basement Closet such a clean gravel. Because this can be very expensive in existing homes, you should get a few opinions as to whether this is necessary. In some areas, there may not be enough How To Stop Mold In A Basement Closet room outside the dwelling to provide proper drainage - in these cases, it is often recommended that interior drain tile and a sump pump be installed to remove water from How To Stop Mold In A Basement Closet basements and crawlspaces. This also can be very expensive.
 
 2. Manage water inside the foundation walls and in the How To Stop Mold In A Basement Closet basement or crawl space floor. If the basement or crawl space has a dirt floor, cover it with 6 mil poly, How To Stop Mold In A Basement Closet overlapping edges by at least 12 inches. Seal any cracks or joints in the foundation wall or slab with an elastomeric caulk. Read EPA's Indoor airPLUS http://www.epa.gov/indoorairplus/construction_specifications.htmL How To Stop Mold In A Basement Closet Construction Specifications "Moisture Control" and http://www.epa.gov/indoorairplus/technical/moisture/1_1.html Technical Guidance to the Indoor airPLUS Construction Specifications.
 
3. Use construction techniques to control water, air movement, How To Stop Mold In A Basement Closet vapor diffusion, and condensation. Use construction methods and materials which promote the drying of building How To Stop Mold In A Basement Closet assemblies. Use construction techniques which reduce the likelihood that warm, moist air will come in contact with cold surfaces, leading to condensation, mold growth, and rot. This includes controlling air movement and using vapor barriers on the warm side of walls and roofs. How To Stop Mold In A Basement Closet Proper flashing and drainage How To Stop Mold In A Basement Closet techniques should be used to keep rainwater out. There are different strategies to achieve this, and the strategies How To Stop Mold In A Basement Closet vary widely depending on the climate. For a good discussion of the approaches, consult a building manual such as the Energy Efficient Building How To Stop Mold In A Basement Closet Association's (EEBA) Builder's Guide for your climate.
 
 4. Roofs. It is important that the roof and flashing details and construction effectively keep water out of the house. It is also important that the roof and attic design addresses the issue of moisture in the form of water vapor to avoid condensation in building cavities. There is no single strategy which will work for all houses in all climate conditions. The important considerations are preventing movement of moisture from the warm side to the cold side of the building envelope, and managing moisture which does pass through the envelope to prevent condensation on building materials.
 
 5. Ensure the How To Stop Mold In A Basement Closet home is properly ventilated, with at least exhaust fans in the bathroom and kitchen and preferably a mechanical ventilation How To Stop Mold In A Basement Closet system designed to ventilate the entire house. (See the http://www.acca.org/Air Conditioning How To Stop Mold In A Basement Closet Contractors of America http://www.epa.gov/epahome/exitepa.htm Manual D and NYSERDA "Homeowner's Guide to Ventilation" for more information.) High relative humidity (RH) can lead to problems with mold, dust mites, and other biological pollutants. How To Stop Mold In A Basement Closet Using exhaust fans in the bathrooms and kitchen can remove much of the moisture that builds up from everyday activities and help to keep RH below 50%. There are exhaust fans on the How To Stop Mold In A Basement Closet market that produce little noise, an important consideration for some people. Another benefit to using kitchen and How To Stop Mold In A Basement Closet bathroom exhaust fans is that they can also exhaust odors and pollutants from these rooms. These fans can be part of an active ventilation system for the entire house, and help to reduce humidity levels. How To Stop Mold In A Basement Closet Vent bathroom, kitchen, and clothes dryer/laundry How To Stop Mold In A Basement Closet room exhausts directly to the outside, not into an attic or other enclosed space.
 
6. Size Air-Conditioning How To Stop Mold In A Basement Closet Equipment correctly. More is not always better. Incorrectly sized equipment can lead to operational and How To Stop Mold In A Basement Closet cost problems. Oversized air conditioning systems can "short-cycle" leading to rapid cooling without reducing indoor humidity levels. This can lead to a variety of problems associated with high How To Stop Mold In A Basement Closet relative humidity. Heat gain and heat loss should be determined for each house. The Air Conditioning Contractors of America provides a recognized standard procedure in the publication, How To Stop Mold In A Basement Closet Manual J®. Equipment should be sized for each individual house because even identically built homes How To Stop Mold In A Basement Closet will be affected by variations such as solar orientation and shading which affect heating and cooling loads. Correct refrigerant charge (not under- or over-charged) and proper maintenance are How To Stop Mold In A Basement Closet also necessary for optimum performance of air conditioners.
 
7. Low How To Stop Mold In A Basement Closet Relative Humidity. Below 30 percent relative humidity, people can be uncomfortable and can suffer from dry mucus membranes which can lead to nosebleeds and infections. How To Stop Mold In A Basement Closet In general, low relative humidity is only a problem during the winter months, when the outside air contains very little moisture. It is this dry outside air entering the home through cracks and openings in How To Stop Mold In A Basement Closet the building shell that causes the inside air to become dry. The greater the amount of outside air which leaks How To Stop Mold In A Basement Closet into the house, the dryer the indoor air becomes. By air-sealing and using energy-efficient construction, uncontrolled air leakage is greatly reduced, a more controlled How To Stop Mold In A Basement Closet indoor environment is created, and moisture can be maintained at acceptable levels without the use of a humidifier. Humidifiers require maintenance to avoid becoming breeding grounds for How To Stop Mold In A Basement Closet biological contaminants.
