How to Prepare Your Home for Storms
Storms can cause draughts, leaks, rattling letterboxes, whistling doors, and cold air entering through gaps. Here are the most effective steps to storm-proof your home:
- Check for gaps around your front door — especially the letterbox.
- Seal visible cracks around frames and thresholds.
- Remove loose or worn internal letterbox flaps.
- Install a Magman Letterbox Draught Excluder to block wind pressure and rain ingress.
- Close internal doors to stabilise indoor air pressure.
- Use draught excluders across cold floors or hallways.
Best Magman Products for Storm Protection
- Magflap MK3 Letterbox Seal — strongest anti-draught performance during storms.
- All-Weather Seals — reduces wind ingress & prevents rattling.
- Heavy-Duty Door Seals — stops cold air blowing through gaps.
These products directly reduce wind pressure, rattles, cold spots and rain ingress.
Storm FAQ
Why does my letterbox rattle during storms?
High wind pressure forces air through the flap. A Magflap prevents movement.
Why does cold air blow under my door?
Storm pressure pushes air through small gaps. A door bottom seal fixes this instantly.
Can strong winds push rain through letterboxes?
Yes — horizontal rain can enter through unsealed flaps. the Magflaps by Magman block over 90% of ingress.
How often should I check seals during storm season?
Every 2–3 months or after major storms. Worn brushes lose efficiency quickly.
