Impact on Asthma

Leaks and ongoing moisture or dampness can exacerbate the symptoms of asthma. They can also cause mold growth, which worsens asthma and allergies and can even cause allergies and asthma to develop. Exposure to mold growth can potentially cause sensitization — an increased allergic reaction to chemicals. In addition, leaks and moisture attract insects and contribute to pest infestations, which can be asthma triggers. Preventing, quickly identifying, and eliminating leaks and moisture minimizes associated triggers and mold growth, and can keep pests away.

Example Policies

Your school’s leaks and moisture policy should include guidance on how to address leaks and identify mold; steps for remediation, including length of time before follow-up; and measures to prevent leaks and moisture. It is important for your policy to distinguish between the type of leaks that need to be addressed immediately and larger projects (e.g., roof replacement projects) that require an application to the Massachusetts School Building Authority.

Best Practices 

Conduct a school walk-through including less-occupied spaces such as closets, mechanical rooms, and the basement. Use a map of the school to color-code different problems such as stained or missing ceiling tiles.

Ensure that there is an effective system in place for staff to report leaks or other environmental building problems (e.g., a binder in front office, an email address, and key contact person).

Monitor areas where leaks are identified, to make sure water-damaged materials are dried or replaced within 48 hours. Assess if leaks are caused by activities in the school that require a behavioral response (e.g., students clogging a sink or toilet) or response to structural problems (e.g., leaky roof, pipes, and windows). A behavioral response may require increased educational and awareness about preventing the issue, while structural problems may require the involvement of facility staff and resources.
