DOORS & WINDOWS
Tackling condensation on windows & doors
THE DIFFERENT AREAS OF CONDENSATION
Condensation is caused when water vapour collects on colder surfaces . This creates a misty appearance , which can turn into a covering of larger water droplets in more severe cases . There are three main different ‘ areas ’ of condensation .:
• Inner condensation , which collects on the inside of your windows
• Outer condensation , which collects on the outside of your windows
• Gap condensation , which collects between the two panes of glass on doubleglazed windows and doors
Both inside and gap condensation cause problems and should be addressed as soon as you can to prevent further issues and expense .
Gap condensation within your double-glazed units seriously reduces the energy efficiency and will have a noticeable effect on the temperature in your household , not to mention your energy bills . If you have more than one failed unit , you could find that your heating bills are higher and that you experience more issues with damp and condensation on the inside of the window , due to the decrease in energy efficiency .
Inside condensation can cause damp or mould in the worst affected rooms . This usually manifests as green or white patches with discolouration of paintwork and / or peeling wallpaper , usually in the upper corners of the affected room . You may also be able to smell the damp as it can emit a rather musty odour .
If you commonly find condensation on the inside of your windows and doors , it ’ s quite likely you ’ ll experience some mould or mildew at some point . If the condensation is leaving puddles of water on your window sills or flooring , you should address the issue as soon as you can . Mould and damp is not just unsightly , but can pose serious problems to your health such as respiratory issues and allergic reactions , so getting it sorted sooner rather than later is paramount .
Outside condensation does not cause problems with your property but may be frustrating , as your external views are misted up .
CONDENSATION SOLUTIONS
For inside condensation , there is no quick fix . Instead , tackling it is an ongoing issue and will mean adapting your lifestyle in some key areas . Firstly , ensuring your home is well ventilated is paramount , as this will allow water vapour to escape and fresh air be drawn into your home . Open a window when you ’ re cooking and when you ’ re in the bath or shower — try to do this all year round if you can . When you first spot condensation , open the window ( or a window in the same room ) a small amount and wipe up any moisture which has already formed with a towel .
Installing a dehumidifier can also make a big difference , and it is worth researching the best size and power for your needs before purchasing one , as there are a wide range of options available . Drying clothing inside the home is one of the worst causes of water vapour , so aim to dry your clothes outside or tumbledry them where possible . Where this is not an option , ensure your windows are open and try not to put out too many wet clothes at once . It ’ s not a good idea to dry clothes in a room which does not get a lot of sunlight due to the direction it faces or because it is in shadow , as this can exacerbate issues with mould , so when indoors is your only option , aim to dry your clothing in sunnier , well ventilated rooms .
Outside condensation should clear on its own and should not stay for very long . However , the severity of it can vary depending on how much sun your home gets . If outside condensation is becoming a problem , your local DIY shop is likely to stock a waterproofing spray which can be applied to the outside of the glass to ensure the condensation cannot ‘ stick ’ to the surface as easily . Check with whoever installed your windows to ensure this does not affect any warranty you may have .
Gap condensation can only be solved by having the unit replaced , which may be under warranty or covered in your home insurance policy . If not , you don ’ t have to worry about replacing the whole window or door as the glazed unit can be removed and a new one can be fitted into the same frame .
