What causes the dampness to rise within internal walls?

There are various causes for the increasing dampness within internal walls. Certain reasons help us understand clearly the active driving force behind the presence of heavy moisture in the walls internally.

Following is a list of the top causes of dampness within your walls:-


  • Failure to Construct a Proper Water-Repellent Structure:-

    Dampness may occur in your internal walls if the water-repellent structure is not built properly, or if there are certain defaults in making the system. It also happens in case the repellant system has been degraded or has become too old.

  • Defective Drain Pipes:- Another significant cause of dampness inside your walls can be damaged drainpipes. If there are any leaks in the guttering, it can lead to a high level of moisture accumulation within the walls. Therefore, it’s essential to ensure that the drainpipe is intact, without any cuts or weaknesses along its length.
  • Crumbs in the Roof Tiles:-

    When small cracks start taking place in the roof tiles, it can also cause water leakage from a particular source. Little cracks will allow the water to move through it which will result in creating a high level of moisture in your internal walls.

  • Condensation:-

    You may have felt hot moist air present in your room sometimes. When this warm wet air gets associated with the cold internal surface of your wall, we call it Condensation. It can certainly give birth to high dampness inside your walls.

Amongst all these causes, condensation is the most common form of dampness which can be easily found even in well-built structures. You may also have suffered from this kind of problem sometimes. It can even create health-related concerns. Therefore, it is important to deal with the issue at the proper time and with the proper solution. So, in the next section of this study, we will be going to discuss the primary causes of condensation dampness to get an idea of why such a problem arises.

This problem can be generally caused due to the:

  • Improper construction of the gutters

  • Destruction to the roof

  • Rupture in the mortar of your wall

  • Defects in the things attached or screwed to the wall

Preventing Damp Issues on Internal Walls


Preventing damp issues on internal walls is just as important as knowing how to treat them. Here are some tips to help you avoid damp problems in the first place:

  1. Maintain Proper Ventilation: Good ventilation is essential to reduce humidity levels inside your home. Ensure that your rooms have adequate airflow, especially in areas prone to moisture build-up like kitchens and bathrooms. Consider using extractor fans or opening windows regularly to allow fresh air in.
  2. Fix Leaks Promptly: Any leaks in your plumbing or roof can lead to dampness on internal walls. Regularly inspect your home for leaks, and address them as soon as they’re discovered.
  3. Insulate Your Home: Proper insulation can help regulate indoor temperature and reduce the chances of condensation forming on walls. Make sure your home is well-insulated to prevent cold spots where moisture can accumulate.
  4. Use a Dehumidifier: In particularly humid climates, using a dehumidifier can help maintain the right humidity levels inside your home, reducing the risk of condensation dampness.
  5. Check External Drainage: Ensure that rainwater is effectively drained away from your property. Faulty drainage systems can lead to water seeping into the walls from the outside.
  6. Seal Gaps and Cracks: Seal any gaps or cracks in your walls and around windows and doors to prevent rainwater infiltration.
  7. Regular Maintenance: Perform routine checks on your internal walls for signs of dampness. Early detection can help prevent the issue from worsening.
  8. Consider Damp-Proofing: If you live in an area prone to damp problems, you may want to consider professional damp-proofing solutions for your internal walls as a preventive measure.
