Draughty Cold Air? How to draught-proof your home

Aluminium Casement Window on a house

If your home is feeling a little breezier than usual, there’s a good chance you’ve got a draught somewhere.

A draught isn’t the end of the world, but if left unattended, it can cause issues with your heating bills and may lead to damp appearing and the ensuing damage that entails.

Luckily, draughty windows and doors are relatively easy to fix. This short guide from Indeluxe Windows should give you a good idea of where to look and how to fix those pesky draughts.

Draughty Windows 

Window draughts are caused when the window casement doesn’t sit flush against the window frame.

Over time, window frames can be warped slightly through exposure to the elements and sometimes the seal can be damaged, allowing the cold air to enter your home.

Run your hand around the window frame to feel where the air is coming through.

If you can’t feel the draught with your hands, a candle or lit match will help; the flame will flicker where the air is coming in. Once you’ve identified where the draught is, you’ve got a couple of choices to repair it.

Foam Strips. These are relatively affordable and versatile. They are foam strips that stick to your windows where the window meets the frame, thereby closing the gap and preventing air from entering your home. However, be sure to get the right size for your window: too thick and it will prevent your window from closing; too thin and you’ll still have a draught. They are also unsuitable for sash style windows. 

Brush Strips. Like foam strips, brushes can be attached to your window frames to insulate the gap between the window and frame. These are more expensive than the foam strips but more effective and can be used to good effect on sash windows. 

Draughty Doors 

There are a number of areas where a door may cause a draught. The sides and bottom of the door can be fixed with brush strips, similar to those described for windows.

A draught excluder can also be used to prevent draughts from the underside of your door.

Other areas of the door responsible for your draughts are the keyhole and the letterbox. A letterbox flap or brush is an affordable solution and reasonably simple to install – just be sure to measure your letterbox before you buy as they come in a wide range of shapes and sizes. 

Keyhole draughts can be eliminated through a simple hinged cover. These are metal discs that can be lifted to use the keyhole and will then drop into place once the keyhole has been used. 

Once you’ve draught-proofed your home, you should start to notice a difference in your heating bills and your home will certainly feel more warm and cosy.
