How to get rid of penetrating damp

When it comes to damp or mould in your home, penetrating damp can often be the most intrusive and difficult to get rid of. External issues such as a leaking roof, blocked drains and damaged water pipes are the main cause of penetrating damp in your home, Regular maintenance to your property is important to keep any issues at bay before they become a serious issue.

What is the cause of penetrating damp in my home

If penetrating damp is already becoming a serious issue within your home, the first thing you need to do is identify the cause before you can treat it. Generally, penetrating damp is caused by one of three external problems:

  • Leaking walls
  • Gaps in window frames and doors
  • Leaking water from damaged gutters and downpipes

Though gutters, drains, windows and doors can all b e fixed relatively easily, dealing with leaking walls can often be a little more of a problem.

It could be that the bricks used to build your home have become old and porous, so are almost acting like a sponge to allow water to get into your home. You can either replace them, which can be expensive and inconvenient, or paint them with an exterior silicone water-repellent fluid or lime wash, that will allow walls to still breathe but stop the water from entering your property.

Alternatively, the penetrating damp in your home may be caused by problems with your cavity walls. Modern homes tend to have a cavity between two walls, to ensure that there is adequate space for any moisture penetrating through the exterior wall to evaporate before it gets to the inner wall. However, if a window or pipework ‘interrupts’ the wall, this can affect how effective it is – and you may need a cavity tray to act as a way to drain any water away from the inner wall to the outside through ‘weep’ holes.
