Damp and Timber Specialists for 50 years

What is Rising Damp?

Damp is something no homeowner wants to deal with. More than just an eyesore creating decorative spoiling, it can invite mould into your home and if not rectified could damage the structural integrity of the property.

Rising damp is just one form damp takes. It happens when groundwater rises through the foundation of your home and up into your floors and walls. Typically caused by a breakdown of your existing damp-proof course (DPC), it can spread deeper into your walls and into more rooms if not caught in time, eventually requiring expensive repair work. That’s why it’s so important to get it treated as soon as you spot the warning signs.

Prokil have been the South’s go-to choice for rising damp removal for over 50 years. When you book a survey with us, we’ll assess your home to quickly get to the root of the problem. We’ll then plan out a course of treatment and draw up a competitively priced quote for our remedial services. Finally, we’ll use our years of expertise to stop rising damp in its tracks, clearing away damaged material and installing an advanced damp-proof course and specialist remedial plastering works wherever damp may seep in.

The end result? A clean and dry home, safe from damp in all its forms.


What Causes Rising Damp?

Rising damp is caused by water from the ground being drawn up vertically through the permeable wall structure. This process is called capillary action.

As the water rises, it brings with it salts and minerals from the ground (namely, nitrates and chlorides of a sodium base). The moisture deposits these salts as it evaporates from the surface of walls, leading to decorative spoiling. The rate at which rising damp progresses depends on your property’s material and the level of moisture in the ground.

If you don’t currently have a DPC installed within your home, or if your existing DPC is faulty, you’re much more likely to experience rising damp. This is because a DPC creates a waterproof barrier in your wall; without it, there’s nothing stopping rising damp from becoming an unwelcome guest in your home.

Why Is Rising Damp A Problem?

Rising damp can cause a range of problems, especially if left untreated for a long period of time. These include:

  • Decorative spoiling
  • Plaster falling off the walls
  • Timber decay
  • Mould and black mould growth
  • Weakened internal structure

These issues are why it’s so crucial to get rising damp dealt with in the correct manner by a qualified, experienced company such as Prokil.
