Is your home feeling frosty this winter? If so, run your hand around the inside perimeter of your exterior doors to feel for drafts. If you feel a chill, then most likely the door weatherstripping needs replacing. Weatherstripping has the tendency to flatten down, crack or become worn over time. If your door is exhibiting these signs, then you should install new weatherstripping to eliminate the cold rushing in. Not only will your house feel warmer, but also you will help save on your home's heating bills.

*Door Weatherstripping Foam

Door weatherstripping replacement kits are available in a number of options. The simplest and least-expensive solution is foam. You can find foam door weatherstripping at any home improvement store and it comes in varying thicknesses and lengths. It only costs a few dollars per roll on average, with industrial strength weatherstripping costing upward of $30.

Foam door weatherstripping has a sticky backing that is protected by paper. All you need to do to install this is to measure the doorjambs, cut an appropriate length of foam, peel off the protective paper and then install the weatherstripping around the doorframe. It's that simple. However, because foam is so easy to cut, it's also vulnerable to dry rot and tearing.

*Door Weatherstripping Kits

As an alternative to low-cost foam, you can also buy door weatherstripping replacement kits that consist of foam wrapped around a wood or metal flange. There are also door weatherstripping kits that are comprised of a vinyl bulb and metal flange assembly. Each door weatherstripping kit that includes a flange contains two long sections for the door side jambs, as well as a shorter section for the top doorjamb.

To install this kit, again measure the height of the side of the door jamb and the length of the top of the door jamb. Next, cut the pieces. Note that you should cope cut the door weatherstripping flanges at 45-degree angles where they butt up against each other. This will enable clean 90-degree angled corners, and provide for a continuous flow of the foam or vinyl bulb insulating material around the doorframe.

After cutting the strips to the correct length, position them tightly against the outside-facing closed door so that the foam or vinyl bulb compress slightly. While holding the door weatherstripping flanges in place, secure them to the doorframe with nails. The nails should be spaced approximately 12 inches apart.

*Installing Door Sweeps

If your door has leaky drafts around the base, you can install door sweeps. Door sweeps are a type of door weatherstripping that attaches to the base of the door so that when the door closes it forms an airtight seal with the bottom of the doorframe.

So if you want to eliminate the drafts in your home this winter, check your exterior doors for drafts and install door weatherstripping replacements where needed. You feel warmer, and you'll save a small bundle on your home heating bills.
