My goal for the exterior of our home was for it to look like a sweet, cozy cottage. Buying new windows just isn’t in the budget, so I decided to recreate a look that I love with the windows we already have.

Here’s a shot of the windows before we started the project.

Before we really even started I decided to use some 1/2” masking tape to mark the lines and give us a better idea of weather or not this was something we really wanted to do.

After a day or two of having the tape up I decided it was go time.

I purchased 4- .75”x.25”x7’ window/door trim pieces from lowes and painted them the same color as our window frame.

The back side that is up against the glass I painted black to match the inside of the window.

(This window is very old.. it was silver metal and because replacing it isn’t an option yet I opted for painting it which is why it’s two different colors.)

We cut the wood to size and measured each section individually to make sure it fit just right.

To attach it to the window we used e6000 glue and painters tape to hold the wood in place while the glue hardened.

After about 6 hours, I removed the tape and used a straight edge razor to remove any excess glue that seeped out of the edges.

All in all I am thrilled with the results. If buying new windows isn’t an option but you like this look, I highly recommend trying this! It’s added just the right cottage charm to our home and it makes a great backdrop for pretty flowers.

    Will the wood not rot from weather exposure since not treated wood?

  • Monique Monique on Aug 07, 2023

    And how do you make them removable, exactly??

    Why did you not use plexiglass? Can’t figure out how just the trim is going to keep the cold out?

      I live in rented property-- but you can do this sort of thing on the INSIDE of the glass--- make removble, for cleaning, and NOT permanently installed-- if you move-- take them with!!!! Good luck on your project!
