Weather Stripping Your Lee’s Summit Home

Fall is an excellent time to ready your home for the upcoming winter weather. Wondering how to start winterizing a house? The first step would be checking your weather stripping to ensure your home is properly protected for the icy winds that are just around the corner. By ensuring you have closed any leaks with weather stripping you can help lower your energy costs this winter.

So what is weather stripping exactly? Weather stripping is the process of sealing openings, such as doors or windows, from outside elements. Weather stripping can also be used to refer to the materials or product used to provide these seals. Weather stripping seals out water or snow along with the cold air and allows you to keep the heated air inside your home.

You can visually inspect the front door weather stripping or the weatherseal around the windows, but there are a couple of ways to test the sealing capability of these seals. On a windy day you can close all your doors and windows and check the seal by feeling around the edges of them to see if you feel any wind coming into your home. A visual check is an even better indicator. Using something that creates smoke, such as an incense stick, you can move the stick around the edges of all doors and windows. If the smoke trail is anything other than vertical you have an air leak.

When applying weather stripping be sure to consult the items packaging for specific instructions, but we have a few general guidelines to keep in mind.

  • Weather stripping should be applied to clean and dry surfaces in temperatures above 20° F.
  • Measure twice and cut once! Make sure you are measuring the area to be weather stripped and the weather stripping twice to ensure you are making an accurate cut.
  • When purchasing weather stripping add up the perimeter of all doors and windows to be weather stripped and add an additional 5-10% to accommodate for waste. You also need to make sure you are purchasing the appropriate width and type of weather stripping needed for that specific application.

There are a number of different types of weather stripping that are required for different applications. There is V-channel (V-strip/Tension seal), which can be used on the sides of double hung windows or sliding windows or the top or sides of a door. Felt can be used around a door or window sash or in a doorjamb. Foam tape is used for the top and bottom of a window sash, around doorframes, or for attic hatches or inoperable windows. And a door sweep is used at the bottom and the interior side of a door.

Window Weather Stripping


Winterizing your home by making sure your windows have proper weather stripping can help lower your heating bill by keeping heated air from escaping out or allowing cold air to enter your home. When applying weatherseal to windows you want to ensure that the weather stripping does not interfere with the operation of the window.

Door Weather Seal

You should ensure that exterior door weatherstriping covers the entire doorjamb, uses one continuous strip along each side, and verify that the weather stripping meets tightly at all corners. Choose appropriate door sweeps and weatherseal thresholds for the bottom of doors. You should choose a thickness that creates a good seal between the door and doorjamb but does not make the door difficult to shut. Because of the continuous rubbing on flooring you should pay careful attention to door bottom weather stripping to ensure that it is still in good condition and providing a good seal. A good door seal provided by adequate door weather stripping can help lower your energy costs by preventing cold air from entering your home and heated air from escaping.
