Damp Proofing HQ – Condensation, Rising Damp and Water Leak Detection Information and Advice

damp proofing

Having a damp home is very common in the UK. The weather is often humid and rainy and this condensation in the air can make its way into homes where it then settles onto walls, fabrics, and carpets. Older homes were often built without vapour barriers and other hindrances to moisture and hydration in the air, which causes damp and condensation in the home. Cellars especially can be damp and humid and see rising damp over the years, if steps are not taken to fix this issue.

Rising damp can be very dangerous to homes as this encourages mould growth which in turn damages building materials and is hazardous to one’s health. Consider what is meant by damp versus condensation and other moisture problems, and how to detect it in your home so you can then better understand how to address this problem.

What is the Meaning of Damp?

There is a difference between damp and condensation. Condensation refers to the changing of matter from liquid to solid, whereas damp refers to the presence of moisture itself. A towel may be damp if it is wet as this means it has moisture, but that moisture is not technically condensation if the towel simply absorbed it.

The two terms, damp and condensation, are often used interchangeably, but condensation is more technically the moisture that clings to surfaces and often occurs when moisture in warm air meets a cold surface. This is why you may see condensation on the bottom of soda bottles or along basement walls; the moisture in the warm air meets those cold surfaces and that moisture then turns from its liquid to its solid state, forming condensation. Cold air cannot hold moisture as warm air can, so when that moisture meets the cold air along the surfaces its state changes, from liquid in the air to solid that clings to those surfaces, thus becoming condensation.

The words are also used interchangeably because they may cause each other or be related to one another; when you have rising damp in your home, there is more moisture to form condensation, and when condensation forms, this holds moisture in the air, making it feel damp. While the two are similar and often spoken of in the same way, it is important to know that they occur differently and are two different things as far as home repair.

Do Damp and Condensation Always Come as a Pair?how to treat damp walls

While damp and condensation often occur together and the words are often interchanged, they do not always come as a pair in every home. Condensation typically happens in cooler areas, so if your home is warm it may be damp but have little condensation that forms. Light dries up moisture in the air, so if your home is bright and gets plenty of sun exposure, this may dry up the dampness in the air before it can condense on walls. This light also helps to heat your home so that the materials of the home are warmer; if your walls are warmer from the outside light, they are less likely to form condensation even if you keep the inside cooler with an air conditioner.

You may also have dampness due to water leaks but these are often concentrated in one particular area of the home, so that they may not lead to dampness in the air but may form condensation on pipes and around other building materials. Larger leaks may cause dampness in the home if pipes are not cold enough to form condensation; the water from the leaks may evaporate into the air and cause it to become damp, even though you have little condensation build-up.

Could the Use of a Water Leak Detection Service Help Cure Your Damp Problem?

If your damp in the home is caused by water leaks, then a water leak detection service may be your best solution. Trying to cover up mould damage is just part of the solution; you need to address the reason for the rising damp in your home and cap off leaks at their source. If you do not address the source of the damp in your home or do not find a solution to condensation issues you may have in the cellar or basement, you will continue to see mould grow and continue to need repairs and replacement for building materials.

A water leak detection meter or service will help you to determine leaks behind the walls and get them fixed before the water does damage to your property.

Could Your Damp be Rising Damp?

Once you’ve determined if your problem in your home is damp or condensation, you then need to see if your damp is rising damp. A little bit of damp in the home may not be dangerous but if it’s rising damp, this can spell trouble for your building materials and property overall. Rising damp typically signals problems with pipes or other materials that may indicate the need for updated plumbing; if you have leaks in one area due to poor or old plumbing, chances are you may then begin to see leaks in other areas as well!

A good water leak detection meter can alert you to rising levels of damp in any are of the home, and if it’s damp or condensation that is the problem. These meters are small and inexpensive and may be used just about anywhere. You may also need to call on the services of a professional in order to determine the location of a water leak and to determine if there is condensation behind the walls. If condensation is forming behind walls, this leads to mould build-up and in turn, may then lead to expensive repair bills. Water leak detection is just half the job when you have dampness or condensation; the source of the problem needs to be addressed but any damage already done to your home also needs to be fixed as well.
