Picking the right trim or casing for your window can greatly increase the appeal of your living spaces by seamlessly blending with the environment. But how do you exactly install your new window trim? Read on as Handyman Connection of Mountain View discusses how.

Step 1:

Start by cutting a 45-degree angle on one of the trim. Hold it properly so that the short end of the angle overhangs by at least ⅜ inches onto the jamb. Mark the other end and make sure it’s flush with the inside of the jamb. The result is your standard 3/16-inch reveal.

Next, you’ll be placing the top piece. Hold the trim 3/16 inches away from the jamb at both ends and right along the base, and then nail the trim into the jamb. We suggest using 1-inch brad nails and space them every 6-inches between each nail. For the thicker portion of the trim, use 2-inch brad nails.

Step 2:

For the side trims, you’ll want to cut a 45-degree miter on the end of the trim. Use the top part as your guide then cut the length by around 3/16-inches in. Remember to nail the trim on the jamb first and then the framing just like with the top piece for a secure fit. If you want, you may also glue and pin the corners to really secure it. Do the same on the other side, taking note of your earlier adjustment. As with the first side trim, use the top piece as a guide.

Final Steps

The bottom trim has the same measurements as the top part so all you really need to do is follow the same adjustments you used before. Use the three trims as your guide and seal the side areas with glue for greater stability and security.
