10 Signs of Rising Damp
There are 3 types of damp that can affect properties – condensation, penetrating damp and rising damp. Rising damp occurs when ground water soaks into a wall or floor – similar to how a sponge absorbs water. A damp proof course and membrane stops water causing damage to a property by sealing and protecting it. A damp proof course is built into a wall above ground level with a damp proof membrane laid beneath a concrete floor. Newer houses will have a damp proof course and membrane although houses built prior to 1875 may not.
Damp proofing can get damaged over time, which can result in rising damp. It could also be the level of the ground is higher than the damp proof course or there is something amiss with drainage. The key signs of rising damp to look out for include:
- 1. Tide marks on the inside and outside wall; usually no more than a metre above ground level
- 2. Damp stains above the skirting board
- 3. Crumbling or rotting skirting boards
- 4. Discoloration or staining on walls
- 5. Deposits causing blistering on walls
- 6. Black mould
- 7. Peeling wallpaper
- 8. Rotting floor boards
- 9. Raised floor coverings
- 10. Smell – you can often smell damp even if you can’t actually see it
The cause of the damp needs to be identified before it can be removed as different damp issues can require different treatments. Frank Schrijver are rising damp specialists with their innovative Schrijver System an economically friendly way to lower humidity levels inside your property, leading to dry walls and continuous protection against damp.
Working with natural ventilation processes, it permanently removes rising damp. Installed outside your home, dry air flows through a series of handmade elements. This causes a drop in temperature and a “cold bridge”, taking moisture from the wall interior where it is deposited within the element. This then evaporates outside resulting in continuous damp protection.
The Schrijver System is the green alternative to damp proofing. With a lifetime guarantee, there’s no mess or redecorating required, and it’s kinder to the environment as no harsh chemicals are used.
