Tools:

Supplies:
  

  • Wood trim boards in various sizes. Primed is less work. Works with both MDF or solid wood.

Header boards: - width of window

  • 1 piece 1 x 6
  • 3 pieces 1 x 2
  • 1 piece 1 x 1
  • 1 piece 1 x 4

Side casing boards: - height of window

  • 2 pieces 1 x 4 (one for each side)

Window sill or stool - width of window

  • 1 piece 1 x 6 and 1 x 2 or to fit (make deeper than original window sill)

Apron: width of window

  • 1 piece 1 x 4

Instructions:
 

  • Remove original outer window molding gently with a pry bar. Leave all other wood intact, including the window sill if flush with wall.

Window sill:

  • Create a window sill to place on top of existing. Determine how wide (left to right) to make the sill by measuring with two side casings dry-fit into place. Cut the sill an inch longer (on each side) past the side casings. Trim inside of sill with a jigsaw to shape. Nail into place.

Side casings:

  • Cut two side casings: measure from window sill to top of window. Nail into place.

Header:

  • Cut header boards to the full width of the window measuring the width of both side casings.
  • Stack header wood, then assemble with a nail gun before installing. 1 1x6, 1 1x2, 1 1x1, 1 1x4 - or install one board at a time on top of the window.
  • Install intact header on the top of the window.

Apron: 1x4

  • Add an apron under window sill. Cut board same width as both window side casings width.

Finishing:

  • Sand, prime, caulk, then paint the window trim with 2 coats of semi gloss paint.
  • Add faux mullions to bare windows by using sign grade vinyl cut into strips. (use color of your window frames)

Notes

Note:
While primed boards are more expensive, they are definitely less work, offering a more professional finish.
Suggestion: in blog post, click on and print the window image with the descriptions and sizes.
