With the rainy season upon us, we wanted to share with you different areas in and around your home to look out for when considering damp, mould and water damage – and what you can do to try to prevent it. 

So, Let’s start this off with the more familiar spots!

1) CondensationWhat is condensation | Whoever You Need

This is probably the most common issue that people see in their homes. Caused by moist, warm air on cool walls and in areas of the home that have generally more moisture in the air such as the bathroom.

A great way to prevent this from happening is keeping rooms well ventilated or painting walls with anti-mould paint which works to prevent the build-up of mould including back mould – use this in areas of high condensation and humidity such as your bathroom and kitchen. Finally, if damp is already an issue in your home, using a dehumidifier will reduce humidity levels making your home less acceptable to mould and mildew. 

What is Penetrating Damp | Whoever You Need
2) Penetrating damp

This is caused by water seeping through your walls which can travel across your walls and even through the ceiling.

The main cause for this tends to be from structural issues with the building itself such as cracked walls, leaking roof, leaking pipes under your bath or faulty guttering. If you notice dark patches on your ceilings or walls you should consider getting a professional out to look at it.

This is exactly how it sounds – from water travelling up through the walls from the ground. This is usually caused by a lack of drainage or the ground outside being higher than the damp-proof course of your home, both resulting in water seeping above and getting in.

You can check for signs such as damaged skirting boards, floor covering lifting up or wet patches and peeling paint or wallpaper. If you notice any of these issues occurring in your home, be sure to get it checked out to avoid structural damage. 

So what areas of the home can be effected?

You may not even be aware that there is a leak behind your shower until it is too late but signs to look out for are, loose tiles, paint peeling from the wall around the shower or a musky smell in that area. If you notice any of these signs, it is important to get it looked at by a professional as soon as you can. Gone untreated, water can leak into the wooden structure of your bathroom and adjacent rooms and cause mould.

5) Behind your dishwasher

This is just like your washing machine except there are a few more areas that can cause issues. Check around the rubber lining of your dishwasher for any cracks or holes – this can be done by placing a piece of paper at different spaces of the door, close and try to pull onto the paper. If you can easily pull the paper out then chances are, you need to replace the rubber around the door to ensure the sill is tight and prevent any leaks. Other checks include the hose for holes, the valve is connected securely, and the draining system is not clogged.

Over the years, window frames can become damaged, window sills can become broken and water can begin to seep into your home and walls. If you think this might be the case for your home, try replacing the sill between the glass and gasket and clean any muck from the bottom of the frame. If your window looks to be leaking around the structure of the window, it would be a good idea to call in a professional window replacement company to avoid any further damage.

Given the nature of the hose pipe, there is a good chance it can become loose over time and begin to leak. Water tends to run down the inside or outside of the wall, causing damage. If you notice a dark patch underneath the pipe faucet then this is a good indication that there is a leak present.

9) Aircon unit

These appliances have a pan inside that collects condensed water which moves around inside to its evaporator coils and then to a drain though a small line. The line can become clogged causing an overflow with the drip pan which can lead to mould accumulating inside. To clean your aircon unit, hoover up any debris within the appliance and using soapy water, wipe down all surfaces of the unit, allowing enough time to dry completely. You can then apply an aircon conditioner cleaner and a mould-inhibitor. Here is a more in-depth article on cleaning your aircon unit.

Leaking chimney | Whoever You Need

10) Around your chimney

The main causes for a damp chimney is salt contamination, condensation and obviously rain. Issues can be either with the chimney stack itself, from water travelling to the base of the stack allowing room for moisture build up. If the mortar around the chimney stack is split or cracking, water can also seep into the chimney breast. The damp proof course may also be damaged, if it has one that is. All of these are things to look out for but with a professional who is equipped to safely check and make the appropriate rebuild.
