What Proper Rising Damp Treatment Involves in Johannesburg
Rising damp is not a surface problem. It begins below ground level when water travels upward through brickwork and enters your interior walls. Paint starts blistering, plaster crumbles, and a persistent musty smell develops. Treating it correctly requires stopping the moisture at its source, not simply repainting over the damage.
We assess how far moisture has travelled, determine whether the original damp course has failed, and rebuild a moisture barrier that permanently stops water from rising through your walls.
For damp issues caused by lateral moisture or exterior leaks, you can also explore our exterior wall waterproofing service.
Why Our Rising Damp Solutions Work
Many Johannesburg homes have old or ineffective damp courses that can no longer block moisture. Our treatment does not rely on temporary fixes or surface coatings that eventually fail.
We use professional chemical DPC injection to form a new horizontal barrier inside the wall. Once the moisture is blocked, we remove contaminated plaster, allow the wall to dry properly, and apply specialist waterproof plasters and coatings that ensure the problem does not return.
This approach stops rising damp permanently, protects the structure, and restores the integrity of your walls.
If moisture is also affecting lower areas such as basements or retaining walls, our structural waterproofing services may be needed for full protection.
Who Our Rising Damp Treatment Is For
This service is ideal for:
• Homes with damp marks creeping upward from the skirting
• Properties with blistered paint or crumbling plaster
• Ground floor rooms with musty or mouldy smells
• Older houses with deteriorated or missing damp courses
• Buildings where damp is spreading into adjacent rooms
• Property owners wanting a guaranteed long term solution
If the damp patch grows after rain or seems to rise from the floor up, it is almost certainly rising damp that needs professional treatment.
Problems We Solve Before They Spread Further
Rising damp can spread faster than most homeowners expect. Our treatment prevents:
• Paint blistering and peeling
• Crumbling plaster and wall softening
• Mould growth and health issues
• Structural weakening of the wall
• Wood rot in skirtings and door frames
• Permanent stains that return after repainting
Stopping the moisture early avoids costly interior repairs and ongoing wall damage.
Long Term Outcomes You Can Expect
Once your rising damp is treated properly, you gain:
• A stable, dry wall with no recurring moisture
• Clean, smooth plaster ready for painting
• Healthier indoor air without musty odours
• Long term structural protection for your foundations
• A permanent barrier that stops damp from returning
Our clients are often surprised at how much fresher and cleaner their interiors feel once the damp is eliminated.
How Our Rising Damp Treatment Process Works
We follow a structured, proven method to ensure the damp is stopped at the root.
Detailed inspection to confirm true rising damp
Moisture measurement and identification of the damp source
Chemical DPC injection to create a new moisture barrier
Removal of salt contaminated plaster
Replastering with damp resistant materials
Application of waterproof coatings if needed
Final assessment to confirm complete moisture control
This process ensures a permanent fix rather than repeated cosmetic repairs.
Common Questions About Rising Damp
How long does rising damp treatment last?
A correctly installed chemical DPC is a permanent solution that lasts as long as the building structure.
Do I need to replaster the walls?
Yes. Contaminated plaster must be removed because salts and moisture remain trapped inside.
How long before I can paint again?
Depending on conditions, walls typically dry within a few weeks after treatment and replastering.
Will the damp come back?
Not if the source is rising damp and the chemical barrier is applied correctly. Our treatments come with guaranteed results.
Can rising damp affect adjacent rooms?
Yes. Moisture can spread sideways. Treating early prevents this.
If the rising damp is linked to exterior drainage issues, our subsoil drainage solutions can help prevent recurring moisture buildup.
