How Interstitial Condensation Affects The Value of Your House

And what you can do about it

 Interstitial condensation is a very common issue in a number of properties. It’s a problem that can linger, and will definitely need fixing before you consider selling a property.

However, it’s not a good idea to try and make repairs happen yourself. Dealing with this issue is not a DIY job. The best thing you can do is identify the problem, then call a professional in to take care of it. Like most problems of this nature (essentially a structural problem) a persistent condensation problem can bring issues around the value of the property.

So, what is interstitial condensation?

It’s something that can cause quite a lot of damage in a property. And this is mostly due to the way it’s formed in a building. Moist and warm air from the inside of a building turns into condensation, when it penetrates the walls. This type of condensation can penetrate walls, floors and ceilings, so can in theory pose a threat to a whole building.

Problems interstitial condensation can cause

  • Mould. This can be a harmful substance, especially to people who have even minor respiratory problems or allergies. And because it has penetrated a wall, for example, it is much harder to get rid of. It is a real problem if mould forms
  • Problems with the timber. Timber can actually rot if it is subject to interstitial condensation. This can lead to structural problems that could threaten the integrity of a building
  • Affects metal structures. Within the walls of  a building, there are usually some metal support sections that make the building more robust. Interstitial condensation can affect these metals, and cause corrosion
  • Frozen water drops. In cold weather, interstitial condensation can create water drops that freeze. These can expand, and if they do so they will most likely affect the infrastructure of a building
  • Damp is a clear signal that there is a problem. But damp can cause health problems, and these health problems can become major if left untreated

In fact, the best thing you can do about this problem is to take preventative measures.

These include:

  • Make an attempt to deal with the condensation inside the building. In areas that are humid in the home, use fans and dehumidifiers to address the issue
  • You could invest in vapour barriers to address the problem. If you choose to go down this route, remember that there is a certain way they should be used, and a proper consultation on the issue should be carried out with professionals
