A window is not merely a home feature, it is a window of opportunity that allows you to look upon the soul of the home.

Including a window, trim elevates the aesthetic while offering a protective layer to the head and jambs of a window. Especially in the case of the exterior window trim, these moldings are designed to offer protection and are best suited when they are waterproof.

While covering any gaps that may be present, window trim also helps set a unique and distinctive style. This is especially true for interior window trims where decoration and insulation are the primary purposes.

For both, the right installation is key. If you have been wondering how to install window trim, let us assure you that is a relatively straightforward process that can be achieved with a base level of understanding.

Some of the tools that you need to have at your disposal for this process are listed below:

    • Air hose
    • Air compressor
    • Caulk gun
    • Brad nail gun
    • Safety glasses
    • Utility knife
    • Miter saw
    • Hammer

Here are some simple steps following which you can install window trim:

 

Step #1: Mark Out the Length

When you decide to install window trim, you must remember to start the process from the top. On one end of the trim, create a 45-degree angle. You have to hold it so that the angle’s short end overhangs the hallway onto the jamb. After this, you will be required to mark the other end with the interiors of the jamb.

Step #2: Space It Out

Position the top piece and clasp the trim at least 3 inches away from the jamb found at both the corners and alongside the window casing’s base. After this, you have to get the trim nailed to the jamb with 1-inch long brads. There should be a gap of inches between each of the brads. The thicker portion of the trim should be nailed to the framing with 2-inch long brads.

Step #3: Inspect The Fit

On one corner of the trim board, cut a 45-degree miter and then, adjust the miter in a way that demonstrates the perfect fit. Then, score a line 3-inches across the cut length past the jamb’s bottom. First, you have to get the nail trimmed to the jab and then, nail it to the window casing framing.

Step #4: Use Glue and Pin

Get the corners fastened and then, use glue and pin, along with 1-inch brads, to join the miter from both directions. As soon as you accomplish this, remove the extra glue splattered around with the help of a damp rag.
