DIY vs Professional Damp Proofing: Which Should You Choose?

We sell both DIY damp proofing kits and a full professional damp proofing service. People often ask which one we actually recommend, the answer depends on three things: how much wall you have, how confident you are with a paint roller, and how badly you want it done this weekend.

When DIY makes sense

• Single room or up to 30m² of affected wall.
• You can clear furniture and access the wall safely.
• You're comfortable mixing and applying with a roller or brush.
• Budget-sensitive: you'll save roughly 60–70% versus a contractor.

When to call us in

• Multiple rooms, double-storey, or external walls above 2.5m.
• Heavy salt damage that needs replastering after treatment.
• Combined damp + mould remediation (we handle both in one visit).
• You want the 6-month workmanship guarantee.

Cost comparison

A typical 25m² lounge wall: DIY Xtreme 5L kit ≈ R1,500 + your weekend. Professional ≈ R3,750 + done in a day with guarantee. Either way you're paying for the same active chemistry, the difference is labour and warranty.
