How can I stop persistent dampness near window sills?« Back to Previous Page

After the rain last month, I noticed a persistent dampness around the window sills in my second-floor apartment. Despite using fans and opening windows to dry out the space, the moisture seems to keep coming back. The walls near the windows are slightly stained, and it’s affecting the paint quality. How can I prevent this dampness from recurring and damaging the interior of my home?

Persistent dampness near window sills can indeed be a challenging issue to manage, especially in the UAE where humidity levels may be higher during certain times of the year. The scenario you've described sounds quite common and may indicate underlying moisture issues that need professional attention.

Firstly, it's crucial to understand the potential causes for this persistent dampness. In your case, since Dubai experiences occasional rainfall and high humidity, especially during the cooler months, there could be a few contributing factors. These include inadequate drainage around the building, poor sealing of windows or doors, structural defects in the building envelope, or even issues with the external coating such as paint or render.

To address this problem effectively, here are some steps you can take:

1. Inspect and Repair External Surfaces: Start by checking for any gaps or cracks in the exterior walls near the window sills. In Dubai, which is part of the UAE, it's important to ensure that these areas are properly sealed to prevent water intrusion.

2. Check Drainage Systems: Ensure that all downpipes and drainage channels are clear and not blocked. This can help divert excess water away from your building’s foundation effectively.

3. Ventilation Assessment: While you've already tried using fans, it might be worth assessing the overall ventilation system in your apartment. Proper cross-ventilation can significantly reduce moisture accumulation. Consider installing a dehumidifier if the area is particularly prone to dampness.

4. Professional Inspection: Given the persistent nature of the issue, it would be advisable to schedule an inspection by a professional environmental consultant or building inspector. They can provide a detailed analysis and suggest specific remedial actions that might include waterproofing solutions for your external walls.

5. Regular Maintenance: Once any identified issues are addressed, ensure regular maintenance is carried out. This includes checking the condition of seals around windows and doors during seasonal changes.

Remember, in the UAE, there are no specific regulations mandating certain actions to prevent dampness; however, adhering to best practices can help maintain the integrity of your property and comply with local building codes that indirectly address moisture management.

If you find it difficult to manage or resolve this issue on your own, don't hesitate to contact a professional company like Saniservice at 800-MOLDS (800-66537) or email hello@saniservice.com for assistance.
