A door seal in place a the foot of a door leading into a tiled room

Overview

Sealing the gaps between your door and door frame is a highly effective way to help draft proof your home. It can help reduce your heating and cooling costs as well as make your home a more comfortable place to live. It's a simple job that's quick to do. This video shows you everything you need to know to get the job done.

Steps

1Prepare door frame

Prepare the surface of your door frame. External door frames tend to gather dirt, so wipe it down with a damp cloth. If you find rough edges or lumps in the frame, scrape them down with a paint scraper and neaten the surface up by giving it a light sand.

2Install the weather seal tape

Start up in the corner where the door meets the jamb. Peel off the backing on the tape and stick it to the top of the door frame. Run the tape the whole way down to the floor, keeping it nice and straight. Try not to pull the tape too hard as you work down the face – you don't want to stretch it. Cut the tape and repeat the process for the opposite side and along the top.

3Cut the aluminium weather strip to size

Aluminium weather strips are made wider than the size of a standard door. You need to cut them down to size before fitting. Start by shutting your door. Mark where the frame meets the door. Open your door and put the weather strip up against the marks. Copy those marks onto the strip, then use a hacksaw and cutting blade to cut the strip.

4Attach the weather strip to the door

Place your strip on the door and mark where the holes need to be drilled. Remove the strip and pre-drill holes with a slightly thinner bit than the screws. Install the screws into the holes – but don't drive them all the way in. This way you can slide the weather strip down onto the screws. Once the strip is in place, push the flap down to make sure that the rubber strip is touching the sill the whole way along. When you're happy that it's sealing properly, tighten all the screws and secure the strip to the door.

5Mount the actuating button on the door frame

The actuating button pushes the weather strip flap down as the door closes. To install the button, shut your door and push the flap down. Then hold the button in place, so that it keeps the strip flap down, and screw it in to place. It's a good idea to mount the button on the hinge side of the door frame.
