Dealing with damp patches on walls can be highly bothersome, as they not only detract from the visual appeal of a room but also create an environment conducive to mould growth. The presence of mould can significantly impact your health, particularly if you have allergies or asthma. Additionally, a cold and damp internal wall can make a living space considerably uncomfortable.
Fixing Damp Wall
Fixing a damp internal wall involves identifying the source of the dampness and taking appropriate measures to address it. Here are the steps you can follow to fix a damp internal wall:
- Identify the source of dampness: Dampness in internal walls can occur due to various reasons, such as leaks, condensation, rising dampness, or penetrating dampness. It's crucial to determine the underlying cause before proceeding with any repairs.
- Fix any leaks: If the dampness is caused by a plumbing leak or roof leak, it should be repaired immediately. Look for signs of water stains, dripping water, or moisture around pipes, ceilings, or roofs. Engage a professional plumber or roofer to fix the leaks and ensure proper waterproofing.
- Improve ventilation: Condensation is a common cause of dampness in internal walls, especially in areas like bathrooms and kitchens. Ensure proper ventilation by installing extractor fans, opening windows, or using dehumidifiers to reduce excess moisture in the air.
- Treat rising damp: Rising damp occurs when groundwater seeps into the walls from the ground. To address this, consider installing a damp-proof course (DPC) or damp-proof membrane (DPM) to prevent moisture from rising. This may require the assistance of a professional damp specialist or builder.
- Deal with penetrating damp: Penetrating damp happens when water penetrates through the walls from the outside. It can be caused by damaged or poorly sealed external walls, faulty guttering, or cracks. Repair any cracks in the walls and ensure that the external surfaces are properly sealed and maintained. It might be necessary to hire a professional to carry out repairs or apply waterproof coatings.
- Remove mould and treat affected areas: If mould has developed on the damp wall, it's important to remove it thoroughly. Wear protective gear, such as gloves and a mask, and clean the affected area with a mixture of water and bleach or a fungicidal cleaner. Allow the area to dry completely before proceeding with any repairs.
- Repair and redecorate: Once the source of dampness has been addressed and the wall is dry, you can proceed with repairing any damage. This may involve re-plastering or repainting the affected area. Use appropriate moisture-resistant materials, such as water-resistant plaster or paint, to minimize the chances of dampness recurring.
- Monitor and maintain: After the repairs, monitor the wall periodically to ensure that the dampness doesn't return. Regularly check for any signs of moisture, mould growth, or new stains. Maintain good ventilation and promptly address any leaks or other issues that may arise.
If the dampness persists or the repairs seem extensive, it's advisable to consult a professional contractor or a damp specialist who can assess the situation and provide tailored advice and solutions.
