A door weather strip is a seal fitted around a door’s frame to block drafts, moisture, dust and insects. The live forecast above shows conditions affecting how well a standard seal performs, especially during cooler or windier weather.
What does a door weather strip actually do?
A weather strip seals the gap between the door and its frame. It stops warm or cool air leaking out, which cuts energy bills and keeps indoor temperature steady. It also blocks rain and dust from entering, and reduces noise from outside. Common materials include rubber, foam, silicone and brush strips.
Which type should you choose for an external door?
For an exterior door, a durable rubber or silicone seal works best. Foam strips are cheaper but wear out faster. A door bottom seal — fitted to the bottom edge — handles the largest gap. Door frame seals, often adhesive-backed, fill smaller gaps around the sides and top. Check the live forecast above; if strong winds are expected, a firm seal is more important.
How to install and maintain a door weather strip
Clean the door frame surface first. Measure the gap, then cut the strip to length. Peel the backing and press it firmly into place. For a door bottom seal, screw or slide it onto the door’s base. Check the seal each season; replace it if it cracks or loses grip. You can find door weather strip kits at hardware stores like Bunnings.
When to replace a door weather strip
Replace it when you feel a draft, see light through the gap, or notice the seal is flattened. A door weather strip bunnings stock includes basic foam and heavy-duty rubber options. For external door seals, choose one rated for outdoor use — it resists UV and rain better.
Can I use a door weather strip on a sliding door?
No — sliding doors need a different seal, usually a brush or pile strip that fits into the track. A standard adhesive strip won’t work and may block the door from moving.
How much does a door weather strip cost?
Foam strips cost around $5–$15 per roll. Rubber or silicone door bottom seals range from $20–$50. Full door weather strip kits are $15–$40 at Bunnings and similar retailers.
Does a weather strip stop all draughts?
It stops most, but not all. Gaps at the hinges and threshold may need additional sealing. A door bottom seal fixes the largest draught, but check the whole frame for smaller leaks.
