Quick DIY Guide to Replacing Garage Door Seals

Replacing garage door seals is an easy task for any home enthusiast. The door’s seal acts as a barrier for dust and unwanted elements from entering your garage. This makes it one of the essential parts of a garage door. This article gives a step-by-step guide on safely and quickly replacing your garage door seal.

Separate the faulty garage door seal

The first step in replacing the garage door seal is to separate the faulty seal from the rest of the track. 

Clean the bottom track of your garage door

Next, clean off any dirt or debris that may have accumulated on your bottom track using a damp cloth or sponge. You can also use a wire brush to scrape any rust or corrosion built up over time. Be careful not to use anything abrasive, as this can damage the new seal and cause damage to other parts of your garage door.

Pull the new seal into the bottom track

Once you’ve cleaned up any loose material on your bottom track, pull in a new garage weather seal into the door track.

Clamp the bottom track in wet caulk 

After removing all old weather seals and cleaning up any dirt or debris, you will need to put some fresh silicone caulk around your bottom track so that when you put your new weather seals back in place, they can stay secure instead of falling.

Remove rust from the garage door seal

Use a hacksaw to cut away the rusted portion of the track. If you do not have a saw, you can use an angle grinder or any other power tool to remove the metal in one piece. 

Once you have removed all the rusted metal from your garage door tracks, use a wire brush to clean up any remaining debris on the surface. Once this is done, paint over areas that need repainting with an epoxy primer or enamel paint. Paint will ensure that no further damage occurs to your garage door.

Remove the Rotting trim of the garage door 

Remove the old trim and sheetrock from the door. You can do this by removing the screws or nails holding down the trim and then prying off the trim with a screwdriver or chisel.

Install a new jamb on your garage door. The jamb is the metal frame that holds up your garage door and keeps it from being able to open too far or close too far. You’ll need to remove any existing screws or nails holding down your old jamb before installing your new jamb on your garage door frame.

Lastly, attach a new stop moulding to your garage door frame. Attaching this stop moulding allows you to adjust how far you want your garage door to remain open. 


A garage door seal is an important part of your door, but many homeowners neglect to replace the seals on their doors or just do it too late when the damage is already done. Fortunately, replacing garage door seals is something you can do yourself and save a lot of money. It’s important to keep your garage door in good working order to last for years and keep you safe from the elements.
