Weatherproofing your door

Job description:

If you run your hand around the edge of your closed door and feel a cool draft, your weatherstripping is probably worn, cracked or deformed. Install a weatherstripping kit with a foam rim and stop energy-wasting air leaks around entry doors . Use a door sweep to seal the bottom of the door. Lift the door by the doorknob to check for loose hinges. Maintaining an airtight seal on your doors is essential for stopping drafts and keeping you warm in your home. Replacing weatherstripping on newer doors is fairly easy. However, older doors were made without integral weatherstripping and it must be added. Weatherstripping kits are available and include two side strips, a top strip and fasteners.

Step by step guide to weatherproofing a door:

1. Measure the top of the frame from side to side when your door is closed.

2. Mark the length on the short section of your new weatherstripping with a clear, sharp line.The weatherstripping kit will come with two long pieces for the side door post and a short piece for the top.

3. Begin with the top and make precise measurements and cuts to get a nice, airtight fit.

4.Place the nails about 2 in. in from each end (to avoid splitting), and space others about every 12 inch.

5.Press the new weatherstripping against the door so it compresses slightly along its entire length . Make sure not to compress it too much as the door won't latch when you close it.

6. Make this cut first, leaving plenty of length for the bottom cut.

7. Make sure that the door shuts and latches easily before you put the nails in place. However, the weatherstripping also needs to fit snug to the door over its full length.

8. For small adjustments, pull the nails and start them in a new spot, or loosen the screws if you’re using metal weatherstripping.

9. When you paint the wood rim, keep the paint off the foam.

10. Measure the width of the door from inside and mark the length on your new sweep. Shut the door, then look for daylight and feel for cold air coming under the door. If you see a lot of light or feel a draft, install a new door sweep.

Caution: Door sweeps last longer, but won't always work if they brush or rub against the floor or carpet when you open the door. If the floor, carpet or rug is even with or higher than your threshold , you can't use a sweep. Enjoy the warmth in your home!
