Should high humidity cause mold growth?« Back to Previous Page

After the heavy rains last month, I noticed a musty smell in both the basement and one of the bedrooms. The humidity levels seem to be quite high, even with the dehumidifier running all day. My kids have been complaining of itchy eyes and coughing more frequently since we moved into these rooms. Could this be from mold? What signs should I look for to determine if there's a problem?

High humidity levels can indeed lead to mold growth under certain conditions. In the context of dubai and the uae, where we experience significant temperature fluctuations and occasional heavy rains, maintaining appropriate moisture levels within your home is crucial for preventing mold proliferation.

In our region, relative humidity (RH) levels above 70% create an environment conducive to mold development. The presence of a musty smell, which you've noted in the basement and one of the bedrooms, along with increased humidity despite running a dehumidifier all day, suggests that your indoor air may indeed be harboring moisture issues. This is particularly concerning given the reported allergic reactions experienced by your children.

Mold spores are ubiquitous and can easily become airborne once conditions are favorable for growth. In dubai homes, areas prone to higher humidity like basements, bathrooms, or even poorly ventilated bedrooms present a risk of mold colonization. The fact that you've noticed these symptoms in both the basement and one room indicates a potential issue that should not be overlooked.

To assess the situation properly, it is highly recommended that you engage with a professional environmental inspection company, such as saniservice.com, to conduct a thorough evaluation. They can use specialized equipment like moisture meters, thermal imaging cameras, and air quality sensors to pinpoint areas of high humidity or mold growth. The number 800-MOLDS (or 800-66537) is available for immediate assistance.

In the interim, while waiting for a professional assessment, you can take some preliminary steps. Increase ventilation in affected rooms by opening windows whenever possible and using exhaust fans to remove excess moisture. Regularly clean areas susceptible to mold growth with solutions containing bleach or borax, which are effective against many common indoor molds. Additionally, ensure that there is proper drainage around your home’s foundation to prevent water from seeping into the basement.

Remember, while these measures can help mitigate immediate discomfort and potential damage, they do not replace a comprehensive inspection by an expert. Mold remediation requires careful handling to avoid cross-contamination or further spread within your property.

By taking these steps, you are proactively addressing what could be a serious health issue for yourself and your family in the uae environment.
