How To Treat Damp Walls On Your Property

Knowing how to treat damp walls could be the crucial difference between a minor inconvenience and a major headache. But to give yourself the best shot at solving the issue, the key is to identify the signs as soon as possible. These include:

  • Condensation
  • Mould growth
  • Musty smells
  • Damp patches
  • Discolouration
  • Curling wallpaper
  • Stained skirting boards

Without the right damp wall treatment, your living space could turn from home to a health hazard before you know it. Use our guide to understand the causes, preventative methods, and what to do if you’re suffering from damp problems.

What causes damp issues? 

Damp walls come in varying forms and can damage your property from both inside and outside. Let’s take a look at the different conditions that lead to them:


If you’re experiencing dampness, condensation is a likely culprit. It occurs when moisture is absorbed into a warm property, and released as liquid condensation when cool. Cold surfaces, such as your walls, will pay the price. 

Penetrating damp

Damp issues inside your home can easily come from outside sources. Rain penetration from the exterior of your property can leak through to your inner walls, absorbing the moisture and leading to dampness.

Rising damp

Groundwater around your home is not uncommon. But without proper damp-proofing this can rise up through your property’s foundations – the impact of which can be felt on your inner walls as damp.

How to treat damp problems

If you’re lucky enough to spot the problem early, you can get to work using simple techniques for treating damp, and even prevent it in future before any further damage is done. Not only could this save you money, but it could save you from living in an unsightly and potentially dangerous environment.


Condensation can be curbed with regular actions around your home. Firstly, improve ventilation with open windows and fans in high-moisture rooms such as bathrooms and kitchens. Steady use of central heating can also help, ultimately reducing dampness on internal walls. 


Removing moss and other debris from your gutter and roof is an easy way of preventing collections of water. By doing this, you’re stopping moisture from leaking through into your interior and dampening your walls. Insulated cold walls and indoor heating can also reduce the impact of penetrating damp.

What should I do if I have damp walls on my property?

If everyday preventative methods aren’t quite cutting it, then you may want to consider taking more rigorous action to ease the affected areas. Here are some suggestions:

  • Use black mould removal and apply a damp seal
  • Repair or protect exterior masonry to prevent penetration
  • Install damp-proof courses and damp-proof membranes for rising damp

These procedures can be beyond most people’s DIY capabilities, so you should always call a professional. Attempting this yourself may not only be dangerous but could result in damage to your home – leading to huge, unwanted costs.
