Weatherstripping is the process of sealing openings such as doors, windows, and trunks from the elements. The term can also refer to the materials used to carry out such sealing processes. The goal of weatherstripping is to prevent rain and water from entering entirely or partially and accomplishes this by either returning or rerouting water. A secondary goal of weatherstripping is to keep interior air in, thus saving energy on heating and air conditioning.
Every exterior door, or door to an uninsulated room such as an attic, must be weatherstripped as required by building codes in various jurisdictions. The materials used in door weatherstripping are thresholds, a piece of material (either a sweep or a J-hook) to match the door to the threshold, and the actual weatherstripping itself. Doors can usually be divided into private homes and commercial properties. Some of these doors receive custom weatherstripping at the factory.
Pre-weatherstripped doors for private homes are usually made of fiberglass or a similar material and are shipped from the factory weatherstripped. The doors have a kerf in the door stop so that a foam, rubber, or vinyl strip can be placed inside for the door to rest against when closed. These doors also have the threshold — usually a molded piece of plastic — nailed to the frame in the factory. These units are not difficult to install and require only very little skill.
Custom weatherstripping, compared to pre-weatherstripped units, requires much more time and is considered to be a specialized skill. Weatherstrippers install a threshold, cut the door and install a sweep or J-hook to the bottom of the door, and nail spring-steel bronze into the doorjamb to seal the gap.
This is a short guide on how to replace the old weatherstripping of your car doors.
Tools that you’ll need:
Step 1: Open the car door and determine how the old seal was attached?whether it used screw fasteners, clips, or if it was glued. If it was glued, use a razor to detach the seal from the door. On the other hand, use pliers to remove clips or fasteners.
Step 2: After removing the old seal, clean the area where it was once attached. Use an Emery cloth to sand clips and clear the holes for push clips using a drill.
Step 3: As soon as it’s clean, put the new seal around the frame, stretching it all the way and adjusting it to match its anchor points with the door frame.
Step 4: Secure the new weatherstrip seal in place by using screws, clips, or glue. If you are going to use screw fasteners, identify the existing anchor points to make the task easier. If you are using clips, just push them into the existing holes. And lastly, if you are going to use glue to attach the seal, make sure you spread an even amount of glue on the door frame and on the center part of the seal. After that, press the seal firmly on the door frame and let it dry for about 24 hours before closing the door.
