Draught Proofing

August 9th, 2018

As the winter kicks and screams its way through February, and your bones are chilled, well, to the bone, the last thing you want to come home to is the freezing cold house. It’s around this time that you start to notice those little cracks under doors and nooks that allow a whispering draught to torment you at night.

Whilst in the summer draughts are a welcome addition, allowing ventilation into your property when uncontrolled they can be a real nuisance and waste a lot of energy. In fact, it is estimated that drought proofing will actually save you on average between £20 and £50 a year.

This isn’t even taking into account the fact that draught free homes are comfortably heated to lower temperatures, enabling you to turn down your thermostat – potentially saving you another 10% off of your heating bill.

So the question is, how can you draught-proof your home?

There are some simple steps to take, and whilst you can make general little improvements there are also some larger improvements that will safeguard your property for years to come. Simply put, the best way to draught-proof your house is to install improved windows and doors, which can not only keep the heat in but the costs of heating down. However, there are still plenty of little things that can be done to improve conditions.


Quite often old casement and sash windows warp and contort over the years leaving audible gaps between the frame and the sill. The installation of brush strips between the sashes and sill will go some way toward combating this, though this is only a temporary fix. You can also get a range of rubber strips which you can fit yourself to act as a buffer between any gaps. Installing new sash windows made with a multi-layered hardwood is a more permanent solution, which will not suffer from the timber movement that many older designs do.


External doors are the next biggest contributor to draughts, and there is a range of products that you can install to help with gaps around and under the door. There plenty of screw-on kits which form a second seal around the door, though these can be unsightly. Alternatives can be found in internal draught excluders which either fit under the door or just inside the frame which will also go some way to keeping warm air in.

Keyholes and Letterboxes

Pivoted covers on both internal and external keyholes, whilst the installation of strong spring mounted letterboxes, as well as sturdy brush units, also prevent air passing through the actual door.

Skirting and Floorboards

Either through poor installation or over years of use, gaps can form between floorboards and the skirting. There are some very good flexible sealants on the market which can plug these holes, and which often stand the test of time.
