Rising damp and leaking roofs quietly destroy homes. Here's how to know when it's time to act.
The warning signs
Damp starts small, a patch of flaking paint, a musty smell in one room, and ends with crumbling plaster, mould and structural damage. Watch for bubbling or peeling paint near the floor line, white powdery deposits on walls, dark patches on ceilings after rain, and mould in corners or behind furniture.
Rising damp vs penetrating damp
Rising damp comes up from the ground through walls, while penetrating damp comes in through roofs, balconies and cracked exterior walls. Each needs a different treatment, which is why a proper assessment matters, sealing the wrong spot just moves the problem.
When to waterproof
The best time is before the rainy season, when surfaces are dry and products cure properly. In Bloemfontein that means acting in late winter or spring, before the summer thunderstorms arrive.
Fix the cause, not the symptom
Painting over damp always fails, the moisture pushes the new coat off within months. Diagnose the source first, treat it properly, and only then restore the finishes.
Frequently Asked Questions
Can I just paint over a damp patch?
No, the moisture and salts behind the paint will push any new coating off. Treat the source first, then repaint once the wall has dried.
Is damp dangerous?
Persistent damp encourages mould, which aggravates allergies and respiratory conditions, and it progressively damages plaster and structure.
How much does waterproofing cost?
It depends entirely on the source and extent of the problem, which is why we assess first and quote in detail, free of charge.
