Air bricks are small openings in the walls of many buildings. Their main origin of existence is air circulation, especially underneath wooden floors and inside wall cavities. Proper ventilation helps keep away dampness and mould, which over time, can even cause structural deterioration. Many prefer air brick covers to keep the openings away from pests, deposits and water, more so external air brick covers for external walls.
Installing air brick covers would look so straightforward that little errors creep in, only to become giant issues in the future.
1. Using The Wrong Size Cover
The Mistake: Most people buy a cover that is too big or too small for the air brick.
Why It Is a Problem: A cover that is too small cover will not correctly protect the air brick, while a big one may not fit well or look nice. A poor fit can allow entry to insects and water.
How to Avoid: Always measure your airbrick before buying the cover. Pick the exact size of cover for the brick. If unsure, take its photo and measurements along to a hardware store or consult one of the online DIY guides.
2. Installing The Cover Upside Down
The Mistake: Most air brick covers have slats or grills designed to face downward, preventing water ingress. Installing them the other way round will defeat this purpose.
Why is it a Problem? The air brick will allow rainwater ingress, causing dampness and damage within the wall if the slats face upwards.
How to Avoid: Check the cover design beforehand. Need labels, instructions, or diagrams showing which side is up? When in doubt, ensure the slats slope downwards.
3. Not Fixing The Cover Securely
The Mistake: Some covers are pushed into place, or improvised weak glue is applied.
Why It Is a Problem: In the case of fitment by an unwary mind, some cover can blow away in strong winds or be pried off by some animals. This leaves the air brick exposed, bringing forth some more damage.
How to Avoid: Use the correct screws or fixings to mount the cover onto the wall; many external air brick covers come with screw holes or fixing kits. Follow the manufacturer’s instructions carefully.
4. Covering Wet Or Damaged Bricks
The Mistake: Covering a damp or crumbling air brick with a cover without addressing the problem is a mistake.
Why It Is a Problem: Moisture getting trapped by the cover and aggravating the condition, moreover, the cover may not stay put on damaged bricks.
Avoiding: Always check the air brick before putting on a cover. If you see damp patches, cracks, or some damage, be sure to repair it first. For severe cases, you may need help from a professional.
Conclusion
Air brick covers make excellent additions to the house, particularly those exposed to weather elements, insects, and dust. Wrong installation, however, would cheerfully do more harm than good. So, by avoiding the above mistakes, you will ensure your air bricks are adequately protected; at the same time, your home will not be impeded in its breathing capability.
