Why Does My Property Need Damp Proofing?

Damp problems are often hidden at first, but they can quickly spread and cause serious damage to both residential and commercial properties. In areas like Johannesburg, where changing weather conditions and moisture exposure are common, proper damp proofing is essential to protect your building and prevent long-term structural issues.

If left untreated, damp can slowly travel through walls and floors, leading to visible damage and unhealthy living conditions.

Without proper damp proofing, moisture can result in:

  • Bubbling or blistering paint on walls and ceilings
  • Peeling plaster and surface deterioration
  • Persistent damp patches on interior and exterior walls
  • Musty or unpleasant odours inside the property
  • Mould and mildew growth affecting air quality
  • Rising damp visible near skirting boards and lower walls

 

Investing in professional damp proofing helps stop moisture at the source, protect your property’s structure, and prevent ongoing repair costs and recurring damp issues.

FAQ

Questions We Have Received

What causes rising damp?

Rising damp occurs when groundwater is drawn up through porous building materials such as bricks, mortar, and plaster. This usually happens when the original damp-proof course (DPC) has failed, deteriorated over time, or was never installed correctly. Signs of rising damp include peeling paint, bubbling plaster, damp patches on lower walls, and white salt deposits.

Can damp proofing be done from inside the building?

Yes. In many cases, damp proofing can be carried out from the interior of the property. Modern injection damp-proofing systems are designed to create an effective moisture barrier within the wall structure. The best treatment method will depend on the source and severity of the damp problem, which is why a professional assessment is recommended.

How long does damp proofing last?

A professionally installed damp-proofing system can last for many years, often 20 years or more, depending on the building structure, moisture levels, and the quality of the materials used. Regular maintenance and addressing any underlying water ingress issues can help maximise the lifespan of the treatment.

Will damaged plaster need replacement?

In most cases, yes. Damp can cause plaster to deteriorate, become contaminated with salts, and lose its adhesion to the wall. Once the damp-proofing treatment has been completed, affected plaster is typically removed and replaced with a suitable damp-resistant plaster system to ensure a long-lasting and aesthetically pleasing finish.
