Having cut a hole through the wall you need to provide a duct to stop debris blocking the hole in the future. Excellent quality air brick protection plate prevents mice and insects from gaining access to properties via holes in air bricks. This is a problem when the central heating goes off at night and the room cools, causing the floor boards and joists to be colder than the humid air around them, in consequence allowing condensation to form on the wood.

So now you know how important they are, make sure you keep your air bricks clear of debris, they are easy to clean, just remove anything piled up against them and use a brush to make sure the holes are free of any build-up. There are instances when proofing a building from the outdoors will prevent a direct route of ingress for mice, and mouse meshing an air brick or fitting an air brick cover can stop mice from easily accessing your building from the garden. If you find you get a major draught then you could fit an air brick cowl, which shelters the face of the vent but still allows air circulation. This can be done very simply with 4 inch (100mm) drain pipes laid side by side as extension tubes for your vents. Sturdy aluminium plate with a circular hole aesthetic, designed to use to cover airbricks – a common access point into properties for rodents.

Homeowners can maintain a cleaner, safer living environment by using air vent covers because they provide a physical barrier that prevents infestations.

A 500mm section of 204 x 60 duct is available for first fix which ensures that connections are accessible after completion of building works. Older houses may have air vents that are made of cast iron, and these can be quite decorative, especially in Victorian houses.

By having air circulating through air bricks into the cavity beneath floorboards cold or damp air does not remain in these spaces and the timbers used in joists and floorboards do not become damp and rot. If unsure, please upgrade to our solid aluminium vent guards that offer 100% protection against any pest. Externally or internally, these covers provide excellent airflow while also acting as an effective barrier against pests. Can be easily installed with a suitable adhesive or fixing screws (not included) If glued, they will need to be held into place until glue goes off. During the winter some condensation will form, usually near the external wall, this could even be confused with rising damp, which is another story altogether.
