Weatherize Your Home

Weatherstripping can help seal air leaks in areas of your home, such as doors, windows and attic access points. If you decide to take on an entire home sealing project, identify all the air leaks in your home, including those in unseen holes or pathways in your plumbing, wiring and HVAC system.

How to Choose Weatherstripping

To choose the best type of weatherstrip for your window or door, make sure that it will withstand the temperature changes, friction, weather and wear and tear associated with the location. See the table below to learn about the different types of weatherstripping.

Weatherstrip Your Doors

Weatherstrip Your Doors

Doors require two different kinds of weatherstripping: door sweeps for the bottom and foam tape for the top and sides.

Step 1

Clean the stop moulding with soapy water and allow it to dry completely.

Step 2

Cut foam tape to fit each side and the top of the door.

Step 3

Peel the back from the foam and press it into the inside of the stop moulding.

Step 4

Cut the sweep to fit the door.

Step 5

With the door closed, screw the sweep to the door so that its bottom is in contact with the floor.
