Framing Your New Sliding Glass Door Without Having To Use Difficult Miter Cuts

Now that you have replaced your home's old worn sliding glass door with a newer model, you need to frame the interior with wood trim. If you are not experienced with cutting miter cuts on wood trim, then you are likely worried about how the results will look. Thankfully, you can use some decorative blocks to prevent the need of making any miter cuts at all.

To this end, here are the instructions you need to easily frame the interior of your home's new sliding door without having to deal with miter cuts or any other complicated construction techniques:

Step 1: Gather All of Your Supplies

To frame your new sliding glass door like a professional contractor, you need to gather the following tools and supplies:

  • two decorative framing blocks
  • three strips of interior wood trim
  • a hacksaw or chop saw
  • a level
  • a small hammer
  • finishing nails
  • wood putty

In addition, you will also need some paint and a paint brush to paint the trim to match the rest of your room once you have finished installing it.

Step 2: Attach the Decorative Blocks on the Top Corners of the Sliding Glass Door

To start this project, you need to attach the decorative blocks on both of the top corners of the sliding door using your hammer and finishing nails. Use the level to make sure the decorative blocks are straight. Once they are level, then nail the blocks to the wall by placing a nail into each corner.

Step 3: Measure and Nail the Strips of Wood Trim on the Top and Sides of the Door

Once the decorative blocks are installed, then hold the strips of wood trim up against the wall and cut them to the right lengths using your hacksaw or chop saw. Nail each trim strip in place with the finishing nails. Nail the trim every foot or so to keep it from bowing as it expands and contracts with weather changes.

Step 4: Wood Putty All of the Nail Heads in the Trim

Finally, before you can paint the wood trim, you first need to place a small dab of paintable wood putty over each of the finish nail heads. While you can use a putty knife for this, it is much easier to simply use the tip of your finger. Place the putty over the nail heads and then wipe off any excess using a cotton cloth. Once the putty dries, then you can paint the trim to match the rest of your home's interior decor. For assistance, visit
