How to Install Garage Door Trim – A Guide for Homeowners

1. Measure the Garage Door:

Before purchasing garage door trim, measure your garage door’s width and height. Measure from the surface of the weatherstripping to the top of the door frame to determine the length of the pieces you’ll need. Be sure to buy a little extra to allow for cutting and waste.

2. Prepare the Surface:

To properly install the trim, clean the surface where it goes and make sure it is dry. If the door has already been painted, sand any rough spots or blistering paint and clean off any debris sticking to the surface. If it is a new door, ensure it is free of debris and clean the surface.

3. Cut the Trim:

Once you’ve measured the width of your garage door, trim the wood to match the length of the door while also allowing for an overhang on either side. If the corners of the doors are curved, you can use a jigsaw to cut the trim. Then, paint the trim with a primer and let it dry completely.

4. Install the Trim:

In this step, two people will hold the trim in place while you nail it up. Ensure the trim’s bottom edge is flush with the door, and the upper edge sticks out. Take a nail and apply it to the ends of the trim, leaving other nails for the center of the trim strip. Use finishing nails with caulk on the heads to create an extra bond on the wood. Repeat the process for all the remaining trim pieces. Be sure to wipe off any excess caulk.

5. Finishing Touches:

Once all the pieces are in place, use wood putty to fill in nail holes and any gaps between trim pieces. Smooth out the putty with a putty knife and let it dry completely before sanding it down. To complete the look, paint over the wood putty with the same color paint as the trim.

6. Caulking:

This essential step helps keep water out of your garage and prevents potential damage. Apply a generous bead of caulk along all the edges where the trim meets the door frame. Use your finger or a putty knife to smooth out the caulk for a clean look.

7. Final Inspection:

Take a step back and check if there are any gaps or imperfections that need to be fixed. If everything looks good, then you’re all set! Your new garage door trim is installed, and your garage will look fresh. Remember to regularly inspect and maintain the trim to keep it in good condition.

5 Considerations Things When You Need to Install Garage Door Trim

1. Measure the Trim

Before you install your garage door trim, you should take careful measurements of the area where you will be installing it. This will help ensure the trim fits correctly and is not too long or short. Be sure to measure the space’s width and height to get an accurate measurement. If possible, you should also measure from wall to wall to ensure that your trim pieces line up with each other.

2. Choose a Trim Material

Once you have measured the space where you will be installing your garage door trim, it’s time to choose a material for your trim. There are many different types of trim materials available on the market today, including wood, vinyl, aluminum, and composite materials. Each type of material has its own advantages and disadvantages, so it’s important to do some research before making a decision.

3. Consider Your Budget

When choosing a trim material for your garage door, it’s important to consider your budget and the look and feel you want for your home. Some materials are more expensive and may require more maintenance over time.

Additionally, some materials may not be suitable for extreme weather conditions or heavy usage areas such as garages or workshops. It’s important to weigh all of these factors before deciding which material is best for your needs.

4. Prepare the Area

Before installing your garage door trim, you should prepare the area by cleaning it thoroughly and removing any debris or dirt that could interfere with the installation process.

Additionally, suppose any nails or screws are protruding from the wall where you plan on installing your trim pieces. In that case, they should be removed before installation to prevent damage to either yourself or the trim pieces themselves during the installation process.

5. Install Trim Pieces

Once all preparations have been made and all necessary tools are gathered together, it’s time to begin installing your garage door trim pieces! Depending on what type of material you chose for your trim pieces, this can involve cutting them down in size using a saw if necessary before attaching them with screws or nails directly into place on the wall surface around the opening of the garage door frame itself.

Be sure to double-check all measurements before beginning the installation process since even small mistakes can lead to costly mistakes later when everything is finished!

Benefits of Install Garage Door Trim

Installing garage door trim can be a simple and cost-effective way to enhance the overall appearance of your home.

It’s also essential to ensure that the trim is level and straight and that all seams are properly sealed to prevent moisture from seeping in. While making these mistakes may be frustrating, they are easily avoidable with careful planning and attention to detail.

Using the Wrong Type of Adhesive or Fasteners
