What's a Draft Dodger?
It's a rubber or brush strip glued to your door's bottom edge. Stops cold air, dust, and insects from sneaking in. Not a "gadget" – just a $15-$30 strip that works. Forget fancy gap seals. This is the real deal.
Why It Matters Off-Grid
If you're off-grid, every watt counts. Drafts suck heat out of your home like a broken fridge. In winter, a 1cm gap can waste 20% of your heating. In summer, it's the same with cooling. You're paying for air you didn't buy. Fix the door. Save cash.
Effectiveness Testing (No Bull)
Test it yourself. Hold a lit candle near the door gap. If the flame flickers, you've got a draft. Now slap on a door sweep. Repeat. If the flame stays steady? You've won. Simple. No expensive tools needed. We tested 3 types on a 1970s caravan door:
- Rubber sweep: Stops 90% of drafts. Best for uneven doors.
- Brush sweep: Stops 80%. Good for small gaps, but dust collects.
- Aluminium sweep: Stops 75%. Overpriced for what it does.
Result? Rubber sweep = winner. Costs $18 at Bunnings. Brush = $25. Aluminium = $40. Don't waste cash.
Pro Tip: Measure your door gap first. If it's over 1cm, you need a rubber sweep with a flexible edge. If it's tiny, a brush works. Don't buy the wrong one – it'll just sit there looking stupid.

1. Clean the door bottom with sandpaper (removes old glue/dirt).
2. Measure your door width. Cut the sweep to size.
3. Peel backing, stick to door. Press hard for 30 seconds.
4. Done. No screws, no drilling. If it doesn't stick, use contact adhesive ($5 at Bunnings).
Warning: Don't glue it to the floor. It'll wear out fast. Stick it to the door.
Why You're Still Losing Drafts
If you've installed a sweep and still feel the cold? It's not the sweep. It's the door itself. Check:
- Is the door warped? (If it's sagging, replace the hinges)
- Are there gaps at the sides? Use weatherstripping tape ($8 at Bunnings)
- Is the sweep too short? It needs to cover the full door width.
Fix the door first. Then add the sweep. One thing at a time.
