Damp Proofing in Sunderland, Newcastle, Durham, South Shields, Gateshead & Chester Le Street


Rising damp is most commonly found in older buildings where the original damp proofing has either failed or has been incorrectly installed. Left untreated it is not only unsightly, but it can seriously damage your property. At Wallseal Preservation, we understand how worrying it can be if you discover rising damp in your property, and we know exactly what to do to remedy the situation quickly and effectively.

What is rising damp?

Rising damp is moisture from the ground that rises up through brickwork and mortar. Groundwater contains minerals and salts that are left on the surface of the walls as they dry out. This draws moisture from the atmosphere, creating a ‘damp’ feeling to the walls and the room in general.

What causes rising damp?

The most common cause of rising damp is the failure of the building’s damp proofing or the ‘damp course’. This can be caused by simple ageing, damage caused by new building work to the property or construction around the outside of the building.

What should I look for?

There are some tell-tale indicators of rising damp that include:

  • A damp, ‘musty’ smell when entering a room
  • Peeling wallpaper or paint, especially at floor level
  • A ‘tidemark’ on the wall above skirting boards
  • A damp, clammy wall surface
  • Salts emerging from the wall surface

What should I do?

If left untreated, rising damp can cause serious structural damage to your property. So it is important to call in the experts as soon as you think you might have a problem. They will be able to assess your situation and most importantly, provide the right action to remedy the situation. This could include the injection of a new chemical damp proof course to the affected walls, and the application of specialist re-rendering tanking techniques.
