14 ways to help reduce condensation in your property

By EnviroVent

Condensation is perhaps the most common form of damp that can appear in your home and can cause structural damage to your property including wallpaper to peel away, damp patches to appear on walls and a build up of moisture, which causes streaming windows.

Left untreated condensation can lead to mould growth which can be potentially harmful and lead to serious health issues and breathing difficulties which is why it is important to reduce humidity levels in a property.

The reason condensation appears in your property is due to a lack of adequate ventilation which causes humidity levels to rise. As we spend more time indoors and make our property more energy efficient the build up of moisture and humidity levels increase.

In fact, four people living in a 3 bedroom property would create 112 pints of moisture a week from just breathing, cooking, showering and boiling the kettle.

So how can you reduce the condensation in your property?

If you constantly have to wipe condensation off your windows and have a dehumidifier running for lengthy periods of time then you may want to think about whole house ventilation as a permanent solution to condensation and to improve the air quality indoors for your tenants or family.

If you are looking for a short term fix rather than a permanent solution then here are our suggestions to reduce the condensation levels in your property:

Tip 1:

If you have a washing machine or tumble dryer in your property, ensure that it is vented correctly. From just one load of washing two litres of water is emitted into the air.

Tip 2:

Where possible, try to dry your clothes outdoors to prevent excess moisture from building up in your property. If you are unable to dry your clothes outdoor then keep them in a bathroom with the door closed and windows open until the clothes are fully dry.

Tip 3:

When cooking food, boiling the kettle or taking a shower, ensure that your kitchen or bathroom door is kept closed to prevent the moisture in the air from going into colder rooms which will cause condensation to form if it touches a cold surface.

Tip 4:

When cooking ensure that you cover your pans with a lid to reduce moisture being created from the water boiling. Also, ensure you are using an extractor hood if you have one above the cooker or an extract fan if you have one installed, these are designed to help reduce moisture created when cooking. Remember, don’t turn off your extractor fan as soon as you finish cooking as the moisture can still be in the air even when you have finished, instead leave it on afterwards for 10-15 minutes to help to clear the humid air. Another option is to purchase an extractor fan with intelligent humidity sensors which speed up when you start boiling water and slow down once humidity levels have returned to normal.

Tip 5:

Similar to when cooking in the kitchen, when you are taking a shower or having a bath ensure that you turn on your extractor fan to remove the steam and moisture that is created when running warm water in a cold environment. This will help reduce the amount of condensation that appears on your bathroom windows and walls.

Tip 6:

Portable gas bottles and paraffin heaters produce a lot of moisture, along with a lot of toxic fumes. Not only is this form of heat causing excess condensation in your property, it is also a health and safety hazard which is stated in most tenancy agreements as not allowed in rented flats.

Tip 7:

Many families have house pets and plants which produce a lot of moisture. Make sure you cover up your aquarium or fish tanks to prevent excess moisture. If damp patches start to appear on your walls or you start to notice more surface condensation on your windows and walls near to your house plants then look to move them outdoors.

Tip 8:

If you don’t have an extractor fan in your bathroom or kitchen then make sure that you wipe down any cold surfaces when you have been cooking or taking a shower to remove any moisture that may have settled on the surface. This excess moisture in the air sits on the surface and will quickly turn to mould if left untreated.

Tip 9:

Do not overfill your wardrobes or kitchen cupboards. A lack of ventilation and air moisture trapped in warm overfilled cupboards can become a breeding ground for mould as the air is not able to circulate freely inside. You might notice a musty smell or clothes might have a damp feeling to them which is a sure sign that the cupboard is overfilled.

Tip 10:

For the same reason as above, make sure that your furniture is at least 50mm away from the surrounding walls so that air can circulate around the property. Try to ensure that your wardrobes are placed against internal walls in your bedroom which will be less cold than external walls and less likely to cause damp and mould problems.

Tip 11:

Ensuring an adequate amount of heating in your property will improve the internal temperature of surfaces in the house and reduce the likelihood of condensation. Also, make sure your home is energy efficient by ensuring you have insulated walls and double glazed windows installed so the heat doesn't escape from the property.

Tip 12:

If you use a room on a regular basis, such as a living room and the weather is not cold outside, open a window slightly to improve the ventilation in the room. Breathing is a major cause of condensation so this will help to improve the ventilation in your property.

Tip 13:

Double glazing, loft insulation and draft proofing will help to reduce the amount of heat that is lost from a property. Installing insulation will help to keep the temperature of the surfaces inside your property at a higher level.

Tip 14:

Adequate ventilation is essential to allow the moisture to escape from a property before it turns into condensation. Installing an energy-efficient extractor fan in the kitchen and bathroom can improve the humidity levels and prevent condensation.

Lots of valuable information. I will definitely add a link on my website to enable people to visit Envirovent's information and solutions to combat this common issue.

We have some rising damp issues around our property. Especially in the winter, like you said. Since the winter will be here so soon I've been looking for tips to reduce the condensation. I like your tip of making sure that our washer is vented correctly. I can see how that would help. Thanks for the wonderful tips. I think they will help a lot.

Some really useful tips here! I've had loads of problems with damp in the past and I always tried using a dehumidifier. Originally I bought a dehumidifier but it didn't work. I ended up buying a PIV unit and it reduced the amount of mould build up in my bedroom - couldn't recommend it enough, especially for people with breathing difficulties.

These are some excellent tips! I had condensation in between the double glazing of one of my window.

I wish my tenants would read this article. I understand that ventilation is required but tenants do not help the issue when they dry their clothes indoors and don't think about putting lids on pans. I've gone above and beyond to ensure my tenants are happy. I have even installed a tumble dryer in one property which I know wasn't used by the last tenant as it still had the instruction manual inside the dryer. Tenants will always complain as they think it is a problem with the house and not the person living in the property.

For some odd reason I find my walls get wet in mild, clammy, damp/wet weather, when its crisp and frosty it's less of a problem, no idea why this should be, I have the top and bottom of my windows open a bit all year round and when I cook windows, door and extractor fan go on, the walls of the house that are the outside walls cannot have things along them in late autumn and winter, where as in spring and summer it's not an issue. Getting fed up the mould ceilings which in this 200 year old house are high so I can't get up there to clean them in spring.

I use crystal granial boxes but have no visual signs of damp or mould on the carpets or walls.

I lived in my property for 8 years before renting out for 3, I've been back a year and my tenants greased all the windows shut and taped all the vents up. Guess what... I have a damp issue!

Would just like to say how pleased we are with the unit we had fitted in our bungalow last year we left leaving feedback till we had given it a full year in all weathers , we had a bad condensation problem and black mould on the window frames and corners of the ceilings, we are pleased to say we haven't had any at all since having the unit installed , we are thrilled this winter not having to wipe all the condensation of all the windows every morning . Anyone thinking of having one fitted you should go a head ASAP .

Thank for your valuable tips for reducing condensation. It's really great to read your tips.
Johnny McCarron Tue, 19th September 2017
We recently moved our washer and dryer to our utility room, just off the house. We have already noticed a huge decrease in moister buildup in the house. Our next step is to add a fan in the bathroom. We have a 7 year old that loves his long hot showers.

Check to see if you have any water leaks, especially under the floor. I found this to be my problem, a leak from a pipe joint under the bathroom floor was causing a major condensation problem, leak repaired condensation gone.
Jeanetta Edwards Mon, 13th November 2017
Where do I get a free advice on condensation from please need to get rid of it from all windows and walls.
Indrajeet Sat, 25th November 2017
Thanks for the valuable information. For the last few weeks every morning, I am seeing moisture on my double glazed window. Today was the worst of all days. I guess its due to the fact that yesterday night was the coldest. Am I right to think that I should not leave the windows open, as the cold air will get through this and builds moisture on window.
