Mold Overview:
Mold and mildew are naturally part of our lives. They are living growing organisms found everywhere, even within your home. Mold needs two primary things to survive and grow, moisture and a food source. Food sources are the most abundant. Paper, cardboard, sheetrock, wood, and any cellulous material can support mold growth. Moisture is the key that connects mold with its food source. Mold spores are microscopic and on virtually every surface in your home. They await moisture to begin their growth cycle. We find moisture through water leaks, high humidity, flooding, etc. Poor air circulation will greatly add to the problem by not allowing proper drying to occur. If materials are not dried properly within 24 hrs., mold growth can occur and quickly spread.
Why are molds a problem?
Molds produce allergens, and can create health problems especially to those who are susceptible to allergies. Certain molds, such as Stachybotrys,(often called "black mold"), Penicillium, Aspergillus, to name a few, can produce mycotoxins, which are potentially harmful to the human body and can cause some serious health issues such as: itchy watering eyes, sneezing, coughing, asthma and other symptoms that are not commonly reported. There is continual research on the effects of mold on humans, and how susceptibility to common molds play a role in personal reactions.
How should a mold remediation or "mold removal" be done?
Mold should be "cleaned up", or remediated, only by a professional certified remediation contractor. A contractor should be certified and follow specific guidelines for mold remediation and water damage. Do not take it upon yourself to clean a mold contaminated area. This could lead to illness and further contamination. First, the water leak, intrusion, etc., must be corrected. Failure to do so will only hinder efforts. Second, the area must be placed under containment and negative pressure, via the appropriate size air scrubbing system. This will help to prevent cross contamination, trap airborne mold spores in a Hepa system and provide the appropriate air changes during the remediation project to clean the air. Third, contaminated materials must be removed properly and contaminated surfaces must be scrubbed and/or sanded if need be, then Hepa vacuumed to collect mold spores. Finally, all surfaces must be treated and/or damp wiped with an EPA approved biocide to kill any surface mold and penetrate porous surfaces.
In addition, if there is an HVAC system in the home, it is highly recommended that the system be cleaned with a Hepa equipped unit and sanitized to prevent re-contamination.
This is a complicated, detailed process and not one for the amateur or weekend warrior to undertake. In most cases, an Industrial Hygienist, or a Certified Testing company is contracted to provide pre and post testing to ensure that the mold has been properly remediated and that levels are equal to or below outside standards.
Mold can never be completely removed from our lives. With every opening of a door, or window, molds enter our homes. If as a homeowner, you have questions, concerns, or notice health problems occurring, contact a Certified Remediation Specialist and have an inspection.
