What is Rising Damp and how can you Prevent it in Your Home?

Rising damp is a common problem for homeowners, but it can be dealt with.

There are three main types of dampness that cause the issue: external sources, internal sources and condensation. External sources are usually due to rainwater getting in through cracks or gaps in the wall.

Internal sources are usually due to water from plumbing leaks seeping through walls or under floors. Condensation is caused by high humidity levels inside your home which cools down as they pass through cold bricks on their way out towards the colder outside temperature.

If you have rising damp, seal up all cracks and gaps in the walls. There are various types of sealants like fibreglass mesh tape that can be used.

If there is water coming through worse than before then it may be due to plumbing leaks that need to be fixed ASAP.

Which Type of Dampness Causes the Issue?

There are two main types of damp that you can get in your home, condensation and moisture penetration.

Condensation occurs when the air is humid and comes into contact with a cold surface. The humid air will condense on the cold surface, such as a cold wall.

The wet surface will dry over time and the moisture will just evaporate and leave no traces. Moisture penetration is more common than condensation and is usually due to water leaking internally.

When moisture penetrates and builds up somewhere, it can cause mould growth. Mould spores can grow and spread all over your home, causing further damage.

If this is the case then you will likely need to contact an expert to come out and inspect the building. When a damp proofing expert has inspected your home and diagnosed the problem, they will be able to issue you with a definitive solution.

How can you Tell if Your Home has High Humidity Levels?

To find if your home has high humidity levels, you need to first figure out if the humidity in your home is the cause of your problem.

Look for signs of condensation or water stains on internal walls, ceilings and window frames. If the condensation is forming on the inside of your house, then you could be dealing with condensation.

However, if the condensation is forming on the outside of your house, then you could be dealing with condensation penetration. If your home has high humidity levels, then you will hear condensation forming outside as the air is absorbed into the cold walls.

In which case you will likely need to hire a damp proofing company. When a damp proofer inspects your house and notices that condensation is forming on the outside, then they will need to work out why this is happening.

To fix condensation penetration, damp proofing experts will first carry out a thorough inspection of your home. They will look for where the condensation is forming and then use this process to work out the cause.
