If you’ve ever noticed rainwater pooling inside your doorway or felt a chilly draught creeping in, your door may be missing an important layer of protection. Water ingress doesn’t just cause discomfort — over time it can lead to warped frames, damp patches, and higher heating bills. The good news is there’s a simple fix: a door weather bar (also known as a rain deflector or drip board).
🌧 Why Doors Leak in Wet Weather
Even modern uPVC and composite doors can suffer from leaks and draughts if they don’t have proper protection at the base. Common causes include:
-
Gaps at the door threshold where the frame meets the ground
-
Heavy rainfall running directly down the door surface
-
Missing or worn-out weather bars or seals
-
Poor drainage around the door area
When water isn’t diverted away, it can seep inside, damaging flooring, skirting boards, and even the door itself.
🔒 The Role of a Door Weather Bar
A door weather bar is a slim strip fitted horizontally across the bottom of the door. Its job is simple but effective: to deflect rainwater away from the threshold. By preventing water ingress and reducing draughts, it helps keep your home warmer, drier, and more energy efficient.
Unlike bulky draught excluders, a weather bar provides a neat, built-in solution that blends seamlessly with your door.
