Wall Damp Proofing Johannesburg

What Proper Wall Damp Proofing Involves in Johannesburg

Wall damp is rarely just a paint problem. It begins when moisture enters through exterior walls, cracked plaster, weak joints, or failed internal barriers. Once inside, it causes bubbling paint, mould spots, and eventually structural weakening if ignored.

Effective damp proofing requires identifying exactly where moisture is entering, understanding how far it has travelled, and applying the correct system to stop water penetration permanently. We work on both the exterior and interior sides of the wall to ensure a complete, long lasting solution.

For damp caused by rising moisture from ground level, see our rising damp treatment.

Why Our Damp Proofing Approach Works

Johannesburg’s walls take a beating from heavy summer storms, intense sun, and day to night temperature shifts that crack coatings and weaken sealants. Quick fixes do not survive these conditions.

We use high performance coatings, fibre reinforced systems, and moisture barriers that remain flexible and watertight. For internal damp, we apply treatments that block moisture at the substrate before restoring the wall surface.

This method ensures moisture is stopped at its entry point and prevented from spreading deeper into your home.

If the damp is caused by water entering through damaged exterior surfaces, our exterior painting and protective coatings can also improve long term protection.

Who Our Damp Proofing Service Is Designed For

Our wall damp proofing work is ideal for:

• Homes with recurring damp spots or bubbling paint
• Exterior walls exposed to heavy storms and direct UV
• Rooms with stained or mould forming interior walls
• Properties where damp returns despite repainting
• Older buildings with cracks or weakened plaster
• Commercial buildings needing durable, low maintenance protection

If you see damp marks that grow after rain or walls that feel cold and damp to the touch, professional damp proofing is necessary.

Problems We Solve Before They Become More Serious

Wall damp spreads quickly when left untreated. Our treatments prevent:

• Water seepage into interior walls
• Bubbling or peeling paint
• Mould growth and odours
• Structural softening of plaster and masonry
• Cracks that widen during storms
• Water stains that return after repainting

Stopping damp early protects both the appearance and structural lifespan of your home.

Benefits and Outcomes of Professional Wall Damp Proofing

Once your walls are properly treated, you gain:

• Dry, clean, and smooth walls
• Long lasting waterproof protection
• Strong external coatings that resist UV and storms
• A healthier indoor environment without mould
• Fewer maintenance problems and repeat costs
• A neater, more durable finish inside and outside

Clients appreciate that their walls stay dry even in the wettest months, reducing long term repair expenses.

How Our Wall Damp Proofing Process Works

We follow a structured, thorough process to guarantee results.

Full inspection of damp affected areas
Identification of moisture entry and mapping the spread
Cleaning and preparation of the surface
Application of the correct waterproofing or moisture barrier system
Replastering or finishing where needed
Final protection coating and quality check

This ensures both the source of the damp and the resulting damage are fully addressed.

For walls exposed to significant runoff or pooling water, stormwater drainage improvements may also be recommended.

Common Questions About Wall Damp Proofing

Does damp proofing fix interior and exterior problems?
Yes. We treat both sides depending on where the moisture is entering.

Can damp come back after treatment?
Not if the correct system is applied and the moisture source is properly sealed.

Do you treat mould as part of the process?
Yes. We remove contaminated sections and ensure moisture is blocked so mould cannot return.

How long do the coatings last?
High quality waterproof coatings can last several years with proper application.

Can you repair cracks before waterproofing?
Absolutely. Crack sealing is a vital part of preventing damp.
