Should damp walls cause musty smells and coughs?« Back to Previous Page

After the heavy rains we had last month, I noticed a persistent musty smell in the bedroom on the second floor. The walls seem to be slightly damp despite having used the dehumidifier constantly. My kids have been coughing more frequently too, which could be related. Is there anything specific I should check or do to address this humidity issue effectively?

Absolutely damp walls can indeed cause musty smells and coughs. This situation is particularly common after heavy rains or flooding events like the ones we've seen recently in Dubai. The persistent mustiness you're experiencing, coupled with an increase in your children's coughing episodes, strongly indicates a moisture issue that needs prompt attention.

In the UAE context, especially in Dubai, humidity levels can be quite high, making it even more critical to address such issues quickly. The dampness could stem from various sources including inadequate drainage, faulty plumbing, or simply excessive indoor humidity not being sufficiently managed by your dehumidifier.

Firstly, you should conduct a thorough inspection of the walls and surrounding areas. Look for any signs of water damage like stains, peeling paint, or bubbling surfaces. Use a moisture meter to check if there's excess moisture behind the walls, as this can be hard to detect visually. You might also notice condensation on windows or cooler surfaces in your home.

Given that you've been using dehumidifiers but still experiencing issues, it could indicate that the humidity level in your home is too high for the system’s capacity. In Dubai, with its warm climate and potential for high humidity even during non-rainy seasons, a whole-house dehumidification system might be necessary to maintain optimal indoor air quality.

Moreover, ensuring proper ventilation can help reduce moisture levels significantly. Open windows when possible, especially after showers or cooking, as these activities contribute to increased humidity in the air. Also, avoid using humidifiers unless strictly needed for health reasons and ensure they are cleaned regularly to prevent mold growth.

Given the seriousness of your situation and its impact on your family's well-being, it would be prudent to seek professional assistance. Companies like Saniservice can provide a comprehensive inspection and remediation plan tailored to your specific needs. They will assess the extent of the moisture problem, recommend appropriate solutions, and ensure that any existing mold is properly treated.
