How to Replace Aluminum Trim Around Garage Door

Is your garage door's aluminum trim looking worn out or damaged? Replacing it can enhance your home's curb appeal and improve functionality. Here's a step-by-step guide on how to replace aluminum trim around your garage door, ensuring a professional finish.

Before you start, gather your tools and materials. You'll need a tape measure, tin snips, a drill, a jigsaw, safety glasses, work gloves, a level, a caulk gun, and, of course, the new aluminum trim. Having these ready will make the process smoother and more efficient.

Preparation and Measurement

Accurate measurement is crucial for a perfect fit. Start by removing the old trim. Use a pry bar or a flathead screwdriver to carefully pry it off. Once removed, measure the length and width of each piece. Write these measurements down for reference.

Next, measure the new trim pieces. It's a good idea to add a few inches to your measurements to account for any mistakes or adjustments. Cut the new trim pieces using tin snips or a jigsaw. Safety first: always wear safety glasses and work gloves when cutting.

Installing the New Trim

Before installation, it's a good idea to prime the new trim. This will help prevent rust and improve paint adhesion. Use a primer designed for aluminum, and allow it to dry completely before proceeding.

Bottom Trim

Start with the bottom trim piece. Hold it in place and mark where it needs to be drilled. Drill pilot holes using a drill bit slightly smaller than your screws. This will make it easier to drive the screws in straight.

Attach the bottom trim using screws designed for aluminum. Use a level to ensure it's straight. If necessary, use shims to adjust the trim's position. Once the bottom trim is secure, move on to the sides.

Side Trim

Installing the side trim is similar to the bottom. Start by holding the trim in place and marking where to drill. Drill pilot holes and attach the trim using screws. Again, use a level to ensure it's straight.

If your garage door has a header trim, install it next. Follow the same process: mark, drill pilot holes, and attach using screws. Ensure it's level and centered.

Finishing Touches

Once all the trim is installed, fill any gaps with a paintable caulk. This will give your trim a finished look and prevent water from getting behind it. Allow the caulk to dry completely before painting.

Finally, paint the new trim to match your garage door. Use a paint designed for aluminum, and apply it in thin, even coats. Allow each coat to dry completely before applying the next. Once the paint is dry, your garage door will look as good as new.

Replacing aluminum trim around your garage door can seem like a daunting task, but with the right tools and a little patience, it's a job you can tackle yourself. Enjoy your improved curb appeal and the peace of mind that comes with knowing your garage door is well-protected.
