How to draught-proof a front door
No matter if your door is composite or uPVC, these tips on how to draught-proof a wooden front door will stop winter chills dead in their tracks.
Fit a brush strip
The bottom of your door is the main culprit for draughts. So, fitting a brush strip is highly recommended. All you need to do is cut the strip to the required length and then fasten it in place with screws or nails for long-lasting draught exclusion. For best results, position it so the brush lightly sweeps the floor.
Add draught strips
Self-adhesive foam draught strips are also highly effective at preventing air leaks around the door frame. Installation is easy — simply cut the draught strip to length, aiming for a tight fit, and stick it in place. You’ll need to ensure the door and frame are scrupulously clean so the adhesive strip sticks effectively.
Seal keyholes and letterboxes
No matter how small the gap, it can let in unwanted draughts. It’s helpful to cover keyholes with an escutcheon that slides out of the way. You can also fit a letterbox flap to keep out cold draughts or invest in a wall-mounted letterbox that doesn’t require any hole in the door.
Use a draught excluder
Draught excluders are incredibly effective at stopping unwanted cold air. And with so many attractive designs, you’re sure to find one that fits your decor. Look for ones that span the door and are weighty enough to stay in place but move when you open the door. Or try making one yourself from an old sweater. Draught excluders also work well for internal doors when you need to keep the warm air in.
Check the door frame
It’s also worth checking around the door frame for any gaps that could let cold air leak in. You’ll need a tube of masonry caulk and a gun to fill any gaps inside and out.
Upgrade your door
If your old front door is notoriously draughty, it could be time for an upgrade. Look for energy-efficient glazing with a high U-value. Wood or composite doors are highly thermally efficient and have a beautiful aesthetic to enhance your home.
