Reducing Draughts At The Bottom Of The Door

The edges of a door can be one of the main areas causing a draught. Moreover, the bottom requires a different fix to the rest of the frame. But it is a relatively easy fix to make a draught proof door.

The best fix at the bottom of a door is to use a door sweep. That is a thin rail that connects to the bottom of the door with a brush attached. Furthermore, a door sweep provides a seal and prevents draughts from entering.

For a temporary fix, you may consider investing in a draught excluder. These work in a similar way but they aren’t as secure or efficient. A common problem for draught excluders is that they can move away from the frame when shut externally. That is why a door sweep is the best choice to prevent a draught at the bottom of your door.


How To Stop A Draught From A Letterbox?

It is relatively easy to stop a draught from a letterbox. The two best options are low cost and can drastically reduce a draught coming through the door. Furthermore, a cause of these draughts is use and incorrect closing of the letterbox. 

A simple way to reduce this is to install a draught excluder on the internal opening. These excluders work in the same way as the door sweep and block the draughts flowing through the door. Alternatively, you could install an external wall letterbox. That could become a considerably more expensive option if you decide to replace the door and to remove the letterbox opening altogether.

Draught Proofing Cat Flaps

It may seem obvious due to the large hole a cat flap creates in a door. However, with the right modifications, you can prevent a draught coming through a cat flap.

First of all, if you don’t require a pet flap for whatever reasons you may want to consider replacing your door to remove the flap. Although, that is not a suitable choice for everyone. You can start by sealing around the outside of the cat flap. That will prevent draughts from entering any gaps. 

A better option is to reinstall a weatherproof pet door. These offer a seal to the outside that allows your pets to enter and exit freely.

Draught Proofing A Keyhole

Usually, it is older keyholes that cause a problem with draughts. You can resolve cold air coming through the keyhole by installing either a cover or a brush draught excluder.

These both work to prevent draughts flowing through an open keyhole and are extremely easy to install. The brush draught excluder can be a more aesthetic option by fitting on the inside of the escutcheon.

Problems With The Door Frame

You may be looking at a costly fix if it is your door frame causing the problems. Wooden doors frames can warp and leave the opening inefficient. 

If the frame isn’t warped but letting in a draught, you may be able to install weather stripping. These are pieces of wood that fit around the door to create a draught proof seal. However, if the frame has warped, it may be time to consider replacing the door.

A new composite or uPVC door will provide more energy-efficiency. Plus, with various styles and accessories, a new door can be as unique as you like.
