We waste enough money and energy trying to keep our homes warm in the winter. Don’t let this energy and money leak through the cracks in your drafty doors. Poor insulation in your doors can have a number of causes. If you can figure out what the problem is, it will make it much easier to repair. Some of the solutions below might be helpful. If you are unable to distinguish what the exact problem is, then just try the solutions below, and your home will be more comfortable, efficient, and inexpensive to heat and cool.
If you have a drafty door, the first thing you will want to check is for loose hinges. This is the first thing you want to check for because if your problem is loose hinges, it is a far easier and cheaper fix than any others. To check for loose hinges, all you need to do is lift the door from the knob. If the door budges either up or down, that means your hinges are loose.
If you discover that your door has loose hinges, just take a screwdriver and tighten the screws. However, if you tighten these screws and still feel a draft, you probably have another problem as well.
Weather Stripping Top and Side Jambs
If you believe that damaged weather stripping is the cause of your draft, you are able to buy weatherstripping kits at many hardware stores. The first step is to buy your kit and read the directions. Then you will want to measure the top of your door frame, followed by the side. You want to make sure these measurements are as precise as possible. Remember that you are trying to stop the draft and make your door airtight.
To ensure that you get this airtight fit, test the weatherstripping before really nailing it in the frame. Ensure that it is compressed just enough, not too much. Make sure that your door will close, latch, and lock.
Install New Sweeps
If you notice that the draft is coming from below the door, especially if you notice you can see light through the bottom of the door when it is closed, then you will need to install new door sweeps. Door sweeps are more durable than weatherstripping. However, for some, weatherstripping will be the ideal option, even in the threshold. To check to see if sweeps will work for you, look at the height of your flooring. Is it an even height with the threshold of your door? Is the flooring higher than the threshold? If you answered yes to either of these questions, you will not be able to use sweeps on your door.
Of course, the first thing you will want to do is measure the length of the threshold to see how long your sweep will need to be. Then, you will cut the flexible flap and flange to size. Put the door sweep in where you plan to install it. Then measure, mark, and drill your pilot holes. Position the new sweep, apply pressure, and drive the screws in where needed. To test the seal and fit, open and close your door. To ensure a great seal, you then want to cut out two pads out of 1/8 inch felt and nail them on the bottom of each side of your door frame.
Use Foam Tape
If you live in an older home or have doors that are slightly warped, foam tape might be a good option to draft-proof your doors. You might also want to consider foam tape if you feel that some of the other suggestions are beyond your skill level. Just be aware that this solution is not as long term as many others. Foam tape is very easy to use. Just make sure the surface is clean.
Then you will measure the foam weatherstrip tape, cut it to size, pull the back off of the tape, stick it in your door stop where needed, check to make sure the tape and door make a seal, and make any necessary adjustments to stop the draft. You want to apply the tape to the door stop on the latch side of the doorjamb and the top. However, when you apply the tape to the hinge side of the jamb, you want to apply the tape to the actual jamb, against the door stop.
Use a Door Snake or Towel
Another possible inexpensive solution to drafty doors are door snakes. These can be purchased at many big box stores or online. It is also possible to make your own so that you can customize it. There are many online tutorials to make your own door snake. If you do not have the extra money to spend on a door snake, although it is less effective, you can use a towel.
Recaulking your doors and windows is another inexpensive choice. Of course, this is a more intensive and time consuming process. If you are feeling a draft through your door, check both outside and inside and see if the caulking has deteriorated over time. It is a good time to recaulk both doors and windows regularly. Shim the jambs behind each hinge making sure that the jamb remains plumb.
