Easy Wood Window Trim

Window Trim Installation

Over the Christmas break we decided to work on our Tiny House, beginning with the Quail Grove office area. This is also where I spend most of my time writing.

We almost have this room completed and over the weekend we installed wood window trim.  This was a fun project that was actually easy from start to finish and needless to say we had the best time working together.

Robert is a whiz with measurements and I’m just happier than ever being outside sanding and staining.

Supplies for this Project Included:

  • Table Saw
  • Electric Sander
  • Finishing Nails and Hammer
  • Wood Stain, paint brush and rag
  • Cedar and Pine Wood

Measuring window boards

Cutting the base Window Board

The windows in this building were framed using 2 x 4 boards and our plan was to trim them with stained pine and cedar.  There’re no specific measurements for this project because windows come in all shapes and sizes.

I’m focusing on how we accomplished this activity and if you like the results these instructions will be easy to implement in your own home.

Beginning, with the base of the interior ledge Robert decided to use cedar.  He measured from inside the existing window ledge in addition to the overhang.

Then he used the table saw to perfectly cut those corner measurements so this piece would be a perfect fit.

From Stain to window trim install

Staining and Window Base Board Install

Once that board was fit, Robert handed it off to me for sanding and stain.  We used American Eagle from Cabot because this color was perfect and it  matches the office furniture.

After sanding is complete be sure to remove additional saw dust before applying a brush with stain.

Cover the entire board and wipe the excess off with a rag.

This board was installed first, using finishing nails.  Hammer from the top and you’re ready to move on.

Staining Pine for Window Trim

Sand and Stain the Pine Boards

This rest of the trim involved pine boards, each piece was cut to fit and then handed off to me for smooth sanding and stain.

I really like working with this pine because the grain always shines through perfectly and it dries fast.

You can also stain boards first and then cut, just remember you’ll still have to touch up the ends before installation.

Window Measurements and install

Inside Window Measuring and Install

Measure and cut the inside boards using pine starting from the left side first, followed by the right.  The top inside board is measured last before we move onto sanding and stain.

Once these pieces are dry, they’re installed the same way as they were measured, left, right and top using a hammer and finishing nails.

Window Frame Measuring and Install

The final step is to frame the window against the wall, this will also cover those inside boards so you have a nice framed window.

Begin by measuring the top board first, line it up with cedar ledge board so the edges match. This will leave the top frame with a little overhang.

Then measure the distance on the left side first followed by the right, cut and finish with stain.

The install for the frame begins with the top board first, then add the left and right boards with a hammer and finishing nails.

That was it, super easy and we completed three windows in an afternoon.  To get a better view of our handy work enjoy this little video.

    Love the way it looks! Trimming out the doors and windows really makes a space look finished. Great job, as usual!

      Thank you – was fun and next up is to finish that trim above and move on to the loft.

  2. Christine says:

    Oh my, Carole! Your office looks amazing! I think you were spot on to add that other window!! You have so much natural light and who wouldn’t want to work in that?! Love the wall color and that desk!! P.s I Totally agree with you on how a positive attitude can change everything!! Have a great weekend!!

    1. Carole says:

      Thank you – that desk goes back several generations, I inherited from my Dad when he passed. Funny thing all the furniture is our sons and when he’s settled off it goes with him, even the desk. I kept one piece of furniture from our downsize for us, a box… LOL

      That natural light is fantastic and this space does make a neat office but it would also make a nice living area. Great weekend to you too!

    Wow! Those windows are beautiful. I can’t believe you did that yourself. And, you make it look easy.

    1. Carole says:

      It really was that easy and so inexpensive, went so much faster when we work together too.

  4. Charlene Dryman says:

    The window looks great. My hubby builds, and I love the staining, also. We use 1 x 4’s for the window trim and also around doors and for baseboards. No sense spending tons of money on fancy trim. I love your office.

    1. Carole says:

      Thank you Charlene – Staining is relaxing and I just love how the grain lifts. I completely agree with you and thanks so much for sharing.
