Draught around door

Draughts around doors can be very frustrating. Unfortunately, doorways tend to be very susceptible to creating draughts as they tend to be in hallways that enable easy air circulation and as large apertures, there are many opportunities for gaps to open up which however, small can be very noticeable.

Common issues

4 main issues cause draughts around doors, air movement caused by natural air movement (convection), damage to seals, items caught in the frame and trickle vents. It is also important to mention that air movement in a property should be promoted to avoid issues with damp and mould but this needs to be in the context of your space being comfortable.


This is the normal movement of air around a door and is caused when cold or warm air moves through a property. Doors can cause this especially if they are in heated hallways where there is a large amount of air movement between upstairs and downstairs. Letterboxes can accentuate this problem if a draught excluder is not fitted. A full-length curtain hung over the door can be a very good way of reducing issues with convection.

Damaged Seals

On an Everest door there are 2 rows of seals around your door one on the leaf and one on the frame. Have a look around the door and investigate for any visible damage, loose seals, gaps or debris between the seal and your door when closed. It could be possible that there is a loose seal. All Everest doors are fitted with Qlon seals which are made of a form of memory foam and do not perish or lose their shape but they can come loose. These will need to be pushed back into place and this can be done by hand. If you are missing a seal please contact customer services and we can arrange for replacement seal to be sent to your home.

Incorrect set up of the door leaf

If all seals are present and intact, please check for any gaps between the door leaf and frame, a requirement to adjust the door position may be needed, please refer to simple door adjustments.

Night/Trickle vents

Finally, you may have a trickle vent installed at the top of the door. These are designed to promote air circulation and do not provide an air-tight seal. They are recommended as part of building regulations to promote good ventilation in a building as they enable small amounts of air circulation. This helps with issues such as damp but as explained above convection will increase the speed of air circulation in extreme hot or cold periods. Its important to note that where fitted they are not designed to be air-tight when closed.
