DIY vs Professional Damp Proofing — Which Should You Choose?
An honest breakdown of the cost, time, skill and risk involved in DIY damp proofing vs hiring a contractor.
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 10-year 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.
