Stop That Sneaky Breeze: How to Seal the Gap Under Your Front Door for Good

Here’s a question for you — have you ever walked past your front door and felt a little whisper of wind sneak through the gap beneath it? Like your door’s got a mind of its own and decided to channel a bit of Antarctica right into your hallway? You’re not alone. Drafts under doors are sneaky little things. They seem harmless, but boy do they add up. Cold toes, rising power bills, rattling pets — no one signed up for that.

Luckily, sealing the gap under your front door is one of those home fixes that’s easier than you think. Whether you're a seasoned DIY-er, a busy parent just trying to keep the house comfy, or someone with a bit more time up their sleeve, this job is worth the afternoon. Let’s roll up our sleeves and get into it.

Why That Gap Is More Than Just a Gap

It’s amazing how something so small can cause so many headaches.

Energy loss: Your heater or air con works overtime when air escapes or sneaks in through the crack. That gap can chew through your wallet before you know it.
Dust and bugs: Gaps are open invitations for creepy crawlies and outdoor mess to make themselves at home. They love an easy entry.
Noise and smells: Live near a busy road or love your neighbours but not their curry? That door gap isn’t doing you any favours.

So, if you’re ready to boot the breeze and reclaim your comfort, here’s how to fix that gap for good.

Step 1: Size Up the Offender

First things first — you’ve got to know what you’re dealing with. Is the gap as thin as a coin, or can you slide half your foot under there? Bigger gaps might need a combo of solutions, but most can be tamed with the right product.

Step 2: Choose Your Weapon

This is where things get fun. There’s something satisfying about picking the perfect gear for the job. Here are a few of the top contenders:

Door snakes: Old-school favourites. Great for renters and super easy to pop in place. We’ve even got cute ones shaped like animals for the kids to name!
Adhesive weather seals: Peel and stick foam or rubber strips that go around the base or frame of your door. Quick, cheap, and easy.
Door bottom seals/draught stoppers: These attach directly to the door and form a snug seal whenever it’s closed. Some even come with brush bristles for smoother movement on uneven floors.
Threshold plates: A more permanent fix — a strip that goes on the floor under the door. Great for wide gaps and heavy-duty wear and tear.

Most of these are a cinch to install with nothing more than a screwdriver (and a good cup of tea nearby). And again — if you’re stuck, we’re always happy to talk you through it at the shop.

Step 3: Lock It Down (Literally)

Once you’ve got your solution sorted, it’s time to put it in. Give the area a quick clean — dusty skirting boards and floorboards can stop seals from sticking properly. If you’re using an adhesive strip or door snake, cut it to length first to avoid the ol’ measure-twice, cut-three-times situation (we’ve all been there!).

For screw-on seals and thresholds, follow the guide on the pack. It usually takes about 15 minutes for a standard door. If it’s an older door that’s warped or uneven, don’t worry. There are adjustable options that work wonders on tricky surfaces.

Added Bonus — The Quiet Life

One of the best surprises when sealing your door is the hush that follows. You don’t realise how much outside noise gets in until suddenly… it doesn’t. Your space feels cosier, calmer, more yours. It’s the kind of fix where you pat yourself on the back every time you pass through the hallway. And your socks? They’ll thank you, too.
