  1. Measure the door

    Weather stripping comes in different sizes, so measure the depth of the door frame before making a purchase. If there is already weather stripping in place, peel off a portion and take it with you to the hardware store to get the same size.

  2. Remove existing weather stripping.

    Peel off any existing weather stripping and use an adhesive remover to remove any remaining adhesive. Lightly sand the area, if required, to remove all traces of the old weather stripping. Clean the area well and allow it to dry completely.

  3. Apply weather stripping

    Measure and cut sections of the new weather stripping and apply it to the entire door frame for a completely weather-tight seal.

  4. Install a door sweep

    Measure the bottom of the door and cut the door sweep to fit it exactly. Close the door and install the sweep so that the bottom of the door sweep is in contact with the floor.
