Mold Remediation Advice
Here are some important questions to consider before the mold remediation process should take place.
- Are there current moisture problems throughout the building? Often leaks and flood water can disappear under floor boards or into water cavities after a water leak, water damage or a flood..
- Have building materials been wet longer than 48 hours? Many times condensation can cause water build up in locations where no leaks or water can get to. Noticing dampness is a very good indication that testing for mold remediation should be done.
- Are there hidden sources of water, or is this humidity too high and causing condensation?
- Are the building residents experiencing musty or moldy odors? When a foul or musty odor is detected mold damage may have ocurred in invisible areas.
- Are the building occupants reporting new health issues? Consistent complaints of people or pets experiencing allergic reactions, often means mold could be forming in damp places. Getting a professional test can reveal the location before mold remediation is recommended.
- Are the building materials or furnishing visibly damaged? Pay attention to consistent or new dampness to the building interior or exterior structure. If it is wet are remaining damp and not drying out quickly, mold damage can start to set in.
Before Mold Remediation, testing and identification is the first step.
Sometimes it is necessary to take air or surface samples to determine the type and/or quantity of mold spores in a certain amount of air or on a given amount of surface area.
For the IAQ indoor air quality professional, this information can be useful in determining where the mold damage and growth is in the building by comparing the concentrations of one area to those of another. Also, it can be a useful tool in determining the effectiveness of a mold remediation project by comparing the beginning concentrations to those at project conclusion.
What are appropriate control methods for mold remediation?
There are a number of options available for mold remediation, depending on the size and type of surfaces affected. Most important is the need to control dust associated with the cleanup activity. Dust should be controlled using damp cleaning methods and by using HEPA vacuuming system. This refers to high efficiency particulate air, meaning that the vacuum filter is capable of removing particles that are 0.3 UM (micron: 1 millionth of a meter) in diameter at 99.97% efficiency.
The goal of mold remediation is to remove or clean contaminated materials in a way that prevents the emission of mold spores and dust contaminated with fungi from escaping the defined work area and entering other occupied or non-abatement areas. At the same time, special care has to be taken to protect the health of workers performing the abatement and mold remediation.
Ideally, any water intrusion incidences should be stopped and cleaned as soon as possible usually within 24 to 48 hours. The more time that passes before removing the water damage materials and the cleanup and drying process has begun the greater potential for mold damage. In all situations, nevertheless, the fundamental cause of water buildup must be remedied or mold growth will recur.
