How to protect your blinds from window condensation

4th January 2021

Some people choose to leave their blinds closed throughout winter, but did you know that this can quickly lead to mould and mildew? The reason for this is condensation forming on the inside of the windows. When it sits for long periods of time, it can result in rotting wood, peeling paint, and mould making itself at home on the blinds. Fortunately, there are steps you can take to protect your blinds from window condensation. Read on to find out more.

Why does window condensation occur?

Condensation happens when warm air comes into contact with cold surfaces, such as windows. When temperatures drop in winter and you have your thermostat turned up, the heater air inside you’re your home collides with the glass that’s been made colder by the cold weather outside. It’s a similar process to your bathroom mirror fogging up after you’ve had a bath or shower. Condensation most often occurs on older windows or windows which are constructed from a single pane of glass. These types of windows lack the insulating barrier which double glazed windows provide.

Reduce humidity in your home

One of the most effective ways of protecting your blinds from window condensation is to reduce humidity levels in your home. Kitchens and bathrooms are particularly humid, so it can be a good idea to use fans in these rooms to circulate air. This can help to remove the condensation that has built up whilst showering, bathing, or cooking. Don’t forget to open the blinds regularly in these rooms. This will let air flow more easily, particularly with awkward windows like bay or corner windows. 

Another thing to consider when trying to reduce humidity in your home is if you have a lot of plants near a window? Many people don’t realise that plants can actually make a room more humid. Therefore, it’s worth spreading them out across several windows or even multiple rooms.

Insulate your windows 

Single-glazed windows are still relatively common, particularly in older homes. If your property has them, it’s worth adding an insulating barrier to help reduce condensation. You could use cling film or even a window insulation kit to limit the transfer of colder air. Placing a thin, clear plastic material around the window frame can create an extra layer of insulation and prevent the loss of heat through the glass. The idea may be simple, but it’s highly effective and relatively easy to do yourself. If your home has single glazed, old, or sash windows, it’s worth considering insulating them to keep condensation at bay.

Check there are no leaks 

Checking for window leaks is a good idea if you’re struggling with condensation. If the problem is only happening on certain windows, you may have a draft problem. If there’s moist air entering the property around a specific window, moisture will collect on that window first. You’ll need to check there are no leaks around the window. You may need to call a professional who can reseal or even replace it, depending on how big the leak is. 

If you’d rather do the job yourself, you should caulk and replace weatherstripping in the gaps. You can also add foam sealant to the area between the frame of the window and frame of the house. Keep in mind that if there are leaks in your windows, this can also mean greater energy loss and rising costs to keep your home warm in the winter. Energy-efficiency plummets when there are gaps in your windows.
