Should I worry about musty smell in son’s bedroom?« Back to Previous Page

After the recent renovation of our living room, which we finished about a month ago, I’ve noticed an unusual smell coming from my son’s bedroom. It’s a musty odor that seems to get stronger at night. The window in his room is always closed since it overlooks the construction site next door, and there doesn’t seem to be any mold visible inside or outside the room. What could be causing this smell, and should I be concerned about my son's health?

The musty smell in your son’s bedroom is certainly concerning and warrants investigation. In the UAE, particularly within the context of Dubai, indoor air quality can be significantly affected by several factors including building materials, poor ventilation, and external influences like construction activities.

Firstly, it's crucial to understand that while you haven't noticed visible mold inside or outside your son’s room, musty odors can still arise from various sources. In the UAE context, where high temperatures and humidity during certain times of the year are common, moisture ingress through walls, windows, or from nearby construction sites could be causing this smell.

The presence of a construction site next to his bedroom window is indeed an important factor to consider. Construction activities can introduce dust particles, volatile organic compounds (VOCs), and other particulate matter that may contribute to the musty odor. Additionally, if your living room renovation involved using materials like adhesives, paints, or sealants, off-gassing could also be a contributing factor.

Given the potential health implications for your son, it's highly recommended you engage in a professional inspection as soon as possible. In Dubai, companies such as Saniservice (you can contact them at 800-MOLDS or email hello@saniservice.com) are well-equipped to conduct thorough indoor air quality assessments and identify any potential sources of the odor.

In terms of practical steps you can take, ensure that your son's bedroom is well-ventilated. If it’s a tightly sealed room due to the window being closed for privacy reasons or other reasons, try to open windows during less windy times when the outdoor air quality is better. Additionally, using an indoor air purifier with activated carbon filters might help in reducing volatile organic compounds and odor.

It's also beneficial to keep humidity levels low by using dehumidifiers if necessary. High humidity can encourage mold growth even without visible signs, so maintaining a relative humidity level below 60% is ideal.

Remember, if the smell persists or worsens, or if you notice any other concerning symptoms such as respiratory issues in your child, immediate professional assistance should be sought to ensure their health and safety.
