How to Install or Replace Garage Door Trim

The garage door trim is more than a decorative border. Trim seals out rain, snow, wind, and pests, protecting your garage better while giving your home a clean, finished look.

Garage door trim can get worn out over time, and you see it warp or crack, the paint peel, or even notice gaps forming. These issues show that it’s time for a garage door trim replacement. In this guide, you’ll find practical tips and easy-to-follow instructions on how to install a garage door trim or replace it.

Tools and Materials You’ll Need for Garage Door Trim Replacement

Before you start, it’s a good idea to round up everything you’ll need for a garage door trim replacement. You’ll need a pry bar to gently remove the old trim and a hammer with a nail puller to handle stubborn nails that don’t want to budge. A measuring tape will help you make accurate measurements so your new trim fits just right. A miter or circular saw is essential for cleanly cutting the new trim pieces.

When it comes to materials, you’ll need to choose between wood or PVC (polyvinyl chloride) trim. Wood is a traditional favorite, but PVC is often the better choice if you live in a rainy or humid climate since it resists moisture, rot, and pests far better.

Don’t forget exterior-grade nails or screws to make sure that the new trim stays put. You’ll also need a caulk gun and some paintable exterior caulk for a clean look that keeps moisture out.

Take the time to lay out these tools and materials so replacing garage door trim feels smooth, stress-free, and efficient.

How to Replace Garage Door Trim: A Simple Step-by-Step Guide

With your tools and materials gathered, you’re ready to transform the look of your garage. Here’s a quick walkthrough on how to replace garage door trim without needing a professional.

Step 1: Remove the Old Trim

First, use a pry bar to gently lift the old trim away from the garage door frame. Take your time and try not to damage the wall or siding around it.

Step 2: Measure the Area

Before you cut new trim, measure the height of the sides and the width of the top of your garage door opening. It’s always a good idea to double-check the numbers to avoid waste.

Step 3: Cut the New Trim Pieces

Using a miter saw, carefully cut your new trim boards to the measurements you just took. For clean-looking corners, cut the top piece at a 45-degree angle on each end so it fits with the side pieces.

Step 4: Install the New Trim

Carefully place one side piece against the garage door frame. Take a moment to make sure it’s straight and fits tightly against the frame. If you have a level, you can use it. Once the part is in the right spot, attach it securely with exterior-grade nails or screws, spacing them about 12 to 16 inches apart. Then, repeat the same steps for the trim on the other side of the garage door. Finally, attach the top trim piece. Line it up to complete the frame, so you’ll see it all coming together, creating a clean frame around your garage door.

Step 5: Seal it Up and Add Some Style

If you’re using wood trim, seal any gaps with exterior caulk to keep out drafts and moisture. Then, paint or stain it to match your home’s exterior.

Professional Tips for a Smooth Garage Door Trim Replacement

Remember that even small details can have a big impact as you work. While working, take a moment to double-check your cuts before you attach each piece. It might seem minor, but getting those measurements right the first time helps you avoid extra trips to the hardware store.

Another step people often overlook is caulking. A clean bead of exterior-grade caulk around the edges not only improves the look of the trim but also seals out moisture and helps the installation last longer.

Sometimes, you might find hidden wood rot or issues with your garage door alignment once the old trim is off. In those cases, it’s probably best to call in a professional. Experienced technicians can handle everything from a quick garage door repair to a complete replacement.
