Mold Resource NEW YORK ASSEMBLY BILL A01466 (2011)

Mold is a type of fungus that appears in areas of a home or property that have been exposed to water. In order for mold to develop, it requires a combination of moisture, warmth and an organic matter to feed on. There are over a thousand variations of molds, both toxigenic and non-toxigenic, that can thrive in a home. Molds spread and reproduce by releasing countless tiny, lightweight spores, which travel through the air...


The governing bodies for Mold and remediation for New York City is among the most stringent in the nation.  This information  is excerpts  from New York City Department of Health and Mental Hygiene with credits and website access below for  “ Guidelines on Assessment and Remediation of Fungi in Indoor Environments”  “Fungi (mold) are present almost everywhere.  In an indoor environment hundreds of different kinds of mold are able to grow wherever there is moisture and an organic substrate (food source). They can grow on building and other materials, including:  the paper on gypsum wallboard (drywall); ceiling tiles; wood products; paint; wallpaper; carpeting; some furnishings; books/papers; clothes; and other fabrics.  Mold can also grow on moist, dirty surfaces such as concrete, fiberglass insulation, and ceramic tiles.  It is neither possible nor warranted to eliminate the presence of all indoor fungal spores and fragments; however, mold growth indoors can and should be prevented and removed if present.” Below is the website and pdf of the guidelines for your convenience.


How can molds effect people?

Some people are sensitive to molds. For these people, exposure to molds can cause symptoms such as nasal stuffiness, eye irritation, wheezing, or skin irritation. Some people, such as those with serious allergies to molds, may have more severe reactions. Severe reactions may occur among workers exposed to large amounts of molds in occupational settings, such as farmers working around moldy hay. Severe reactions may include fever and shortness of breath. Some people with chronic lung illnesses, such as obstructive lung disease, may develop mold infections in their lungs.


In 2004 the Institute of Medicine (IOM) found there was sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, cough, and wheeze in otherwise healthy people; with asthma symptoms in people with asthma; and with hypersensitivity pneumonitis in individuals susceptible to that immune-mediated condition. The IOM also found limited or suggestive evidence linking indoor mold exposure and respiratory illness in otherwise healthy children. In 2009, the World Health Organization issued additional guidance, the WHO Guidelines for Indoor Air Quality: Dampness and Mould [PDF - 2.52 MB]. Other recent studies have suggested a potential link of early mold exposure to development of asthma in some children, particularly among children who may be genetically susceptible to asthma development, and that selected interventions that improve housing conditions can reduce morbidity from asthma and respiratory allergies, but more research is needed in this regard.

Mold Remediation/Cleanup and Biocides

The EPA website below:  The purpose of mold remediation is to remove the mold to prevent human exposure and damage to building materials and furnishings. It is necessary to clean up mold contamination, not just to kill the mold. Dead mold is still allergenic, and some dead molds are potentially toxic. The use of a biocide, such as chlorine bleach, is not recommended as a routine practice during mold remediation, although there may be instances where professional judgment may indicate its use (for example, when immune-compromised individuals are present). In most cases, it is not possible or desirable to sterilize an area; a background level of mold spores will remain in the air (roughly equivalent to or lower than the level in outside air). These spores will not grow if the moisture problem in the building has been resolved.

Checklist for Mold Remediation

Investigate and evaluate moisture and mold problems. Please note that this checklist was designed to highlight key parts of a school or commercial building remediation and does not list all potential steps or problems. This checklist is also available separately - Checklist for Mold Remediation (PDF) (1 page, 20 K, About PDF)


• Assess size of moldy area (square feet)

• Consider the possibility of hidden mold

• Clean up small mold problems and fix moisture problems before they become large problems

• Select remediation manager for medium or large size mold problem

• Investigate areas associated with occupant complaints

• Identify source(s) or cause of water or moisture problem(s)

• Note type of water-damaged materials (wallboard, carpet, etc.)

• Check inside air ducts and air handling unit

 Throughout process, consult qualified professional if necessary or desired
