Causes of Rising Damp

Most properties are made with some sort of protective barrier around the bottom of the property. This is to help prevent water seeping in and rising up through the property. This form of damp proofing can be achieved with the use of slate, bitumen and plastic. Which material a building has will depend on when the property was built and some older properties damp proofing may erode over time, some older properties may not even have these measure put in place to begin with.

Treatment for Rising Damp

When it comes to treatment for rising damp it is recommended to not try and deal with it yourself. With damp, it can be difficult to understand the full extent of the problem before it is tackled head-on. Not only can the extent of rising damp be a lot worse than you thought, there could also be harmful bacteria in the damp that may require specialist equipment to deal with safely.

Painting or wallpapering over rising damp will not help the problem but can, in fact, make it worse. Damp isn’t simply moisture on a wall, this moisture must come from somewhere, so getting a professional to determine the cause of the problem is essential for effectively dealing with the situation. If the route of the problem is not treated successfully the problem will just keep coming back, costing you more time and money.
