5 top common causes of damp in the home

Most home owners will have to deal with damp at some point in their life, and it is important to be aware of the factors which encourage damp. This information can help you from the moment you first think about buying a house through to any issues which may arise many years down the line.

Keep an eye out for damp issues in these areas of your home for damp free living!

Leaking gutters and rainwater pipes

This is probably the most common cause of dampness in solid external walls, particularly above installed damp courses. Guttering and water pipes can become clogged with debris such as falling leaves, which need to be checked regularly and cleared out. The chances are that your guttering is high up, meaning that it can be precarious for you to clear them out yourself – especially if you are not confident with heights. There are numerous guides online to help you with your type of guttering if you want to do it yourself, or check with local tradesmen who can offer this service.

High ground levels

If your home is on a slope, then the ground may be built up against the side of your home. On older buildings this can increase over the years without you noticing it, leaving the ground level higher than the damp proof course. If the damp course is too close to the ground level, this can also be an issue. The damp proof course should be at least 15cm above the external ground level.

Blocked vents

Ground floor vents can cause a build-up of moisture in wooden beams and walls. This can cause condensation in hidden areas and slowly rot timbers. Depending on the structure of your house, this may be a relatively minor issue or a serious one, but it should still be rectified. Even if it is a ‘minor’ issue, it can lead to greater problems further down the line and exacerbate other damp related problems.

Chimneys & hearths

Chimneys have reduced functionality compared to previous generations, but they are still vital for your heating systems and for the transfer of waste gasses to keep your home safe. Although they are designed to let gasses out, they can often form a conduit for damp to enter your home. This can come directly in through open chimney pots from rain water, or by the drawing up of ground water through chimney breasts and walls.

General build quality

Although it shouldn’t be, poor build quality is a leading factor in the occurrence of damp issues in the home. When corners have been cut and jobs have been completed inadequately, it can void the installation of a damp proof course. You should check thoroughly around your property, paying special attention to external walls and any joins such as windows and doors.

When all of these factors are taken into consideration, you should have a good head start on preventing damp issues within your home. If issues do arise, then you can be sure that the selection of damp treatments we stock will help you.
