Damp Proofing

4 Causes of Damp you Need to Know About

Damp is a problem you should never ignore as it can cause serious health problems to people living in your home as well as problems within your property. While you can remove the nasty look of damp and mould easily, you’re only removing the symptoms rather than the cause.

To treat damp effectively, you need to know the causes of damp. We’ve put together 4 common causes of damp that you should know about to help identify where your problem is coming from.

1. Building defects

One of the major causes of damp is a defect in the building materials. Cracked mortar can give moisture an entryway into the property, which over time can result in damp.

The best way to check whether you have a damp problem related to the building materials is to check whether there is a watermark on an exterior wall. Then you can check whether there are things such as cracks and gaps around windows and get them repaired as soon as possible.

2. Excessive condensation

Another big problem leading to damp and mould is too much condensation, which can happen if there isn’t enough ventilation. When steam hits cold walls, it leaves surfaces wet to the touch. This is particularly a problem in bathrooms and kitchens. Over time, this causes mould to grow.

If your walls are already insulated to the highest level, it can be difficult to solve this problem. Try improving your ventilation, like putting extractor fans in the kitchen and bathroom, and opening windows when you’re cooking and showering. You could also use a dehumidifier.

3. Failed or inefficient damp proofing

Watermarks or mould on ground floor walls indicate rising damp, which is not a problem you want to have around for very long. This happens when there is too much water in the ground with nothing to stop it rising up the walls. This can be due to lack of damp proofing or damage to the wall.

If you think you’ve got rising damp, you’ll need to install or repair the damp proof course at your property, and you could consider having a damp proof membrane installed too.

4. Damaged roof

Loose or missing roof tiles and other materials can encourage damp to form on ceilings or at the top of walls on upper floors. It’s important that you get a professional to check the roof and do any repairs necessary.

You might also want to get your loft inspected at the same time to ensure that water hasn’t been penetrating through for a long time.

Although damp can be a nightmare, luckily there are plenty of professionals to help you damp proof your home and prevent the causes of damp. Use our service to get up to 4 quotes from reliable contractors in your area.
