Replacing Door Molding

Hi All,

It’s time to tackle a home project! My cat that passed away in March had claws and was over 16 years old. She liked to scratch at the door frames to mark the rooms as her domain… and I think claim us too since we slept in the rooms. Anyway, so because of that, and because our new cat doesn’t seem to have the same inclination… it’s time to replace the damaged moldings.

Here is a video where I show and explain to you how to take them off first and then clean the scilicon caulking off to get a good clean finish on the new molding when installing it.

I then continued the with this no talking sped up video of me installing and putting on the caulking. In the middle (at about 6 minutes) I show the tip of the tube cut at a 45 degree angle so that it’s easier to apply in a fine line:

After the caulking has sat for at least 24 hours to cure you can then tape and paint it to blend in with the existing walls and framing around it, as well as over the caulking itself to get rid of the nail look and generally just make it all clean looking again.


  • Xacto knife (I’m using a Slice cutter from Amazon, a part goes to Autism research.)
  • Claw hammer
  • Molding
  • Saw
  • Mietere box (I used this….I still love it for my purposes.)
  • Silicone caulking
  • Paper towels or cloth to clean the silicone up after

Instructions from start to finish of my project:

  1. Start by taking a picture of your molding and measuring the thickness, width, and height before going to the store to make sure you get the right molding. They come in many varieties so you want to make sure and get the right one.
  2. My doors are 83 1/4 inches high at the point of the 45 degree angle so I got the moldings that matched my existing ones that were 84 inches high. Then used my mietere box to cut the 45 degree angle at the top making sure to cut at the correct angle so that the thickest edge would be on the outside of the door with the tallest part of the 45 degree angle on that side. (Double check… I had to get a replacement for one of mine because even knowing this… I didn’t double check.)
  3. Once that’s done, you’ll need to paint them the desired color. (I did this before taking the other trim off so that I could put the new on right away and not have my kids putting their fingers… or anything else in the area of the door frame and the drywall…..the things we parents have to pre-plan for. 😉 You only need to paint the front and sides however as the back and ends won’t show.
  4. From here now it’s time to take off the old molding:
    • Slice with your Xacto knife along all edges that have silicone… usually you’ll have to do left, right, along any baseboard and along the 45 degree angle.
    • Once that’s done, using a claw hammer or can use this recommended tool as well, you’ll want to pry the old molding up being careful to look for any paint that might be sticking that you’ll want to use your knife on to not peel all the paint up off your walls.
    • After you’ve removed the molding make sure to remove any nails in the molding or the wall for safety reasons. (I also then reuse those nails if I can in the new molding, which I was able to do above.)
    • Also you’ll want to clean the area that you took the molding off of by ensureing no extra silicone was left behind and then wipe with a very damp cloth to remove any dust to give the best seal for the new molding.
  5. Apply Silicone to the wall and other places that the molding will touch. You want enough to do a thorough job, but not enough that it will all gush out when you nail up the new molding. You don’t want to waste it. You can see me apply it in the second video above.
  6. Put the molding in place holding for about 5 seconds to ensure it won’t slide during the nailing process….you don’t want a crooked door look.
  7. Nail in place. I used 12 nails to apply 1 side molding to the 8 ft door.
  8. Wipe away any excess silicone oozing out and apply it into the grooves of the edges of the molding. You’ll want to then apply more to the molding edges as well to get an even line of silicone.
  9. Once that cures for at least 24 hours…. Wash with a damp cloth to ensure you’re not painting over dirt. Also while you’re there you may start to see other blemishes… take it from me… always attempt to wash any blemish away before painting it. Otherwise you could just be trapping dirt and other yuckies.
  10. Now go ahead and tape off and paint to get your desired finished look. This took me a few weeks start to finish for me… but that’s becuase I would take days in between to do the next step with everything else crazy in my life happening in one fell swoop. lol. The replacing of the actual molding after painted and cut was honestly 20 minutes with me taking my time to do it right and neatly for each side. The most time consuming part is all the painting.
  11. Enjoy your fresh new look again!!

Have a great day, and keep creating!!

I am a mom of 2, wife, and am always looking to create something myself instead of buying it. I met Katy from Little Katy Bugs after becoming a mom, and we both love to craft, both have active families, and a tactful way of telling others what we truly think. I LOVE THAT!!! Art is subjective and so is crafting. So, you may not love everything we make or do, but our goal is to inspire you to create yourself and make things that you will LOVE! We do still sell some of our crafts on the site, at craft fairs, and Katy now participates in a booth store front. Check out our Facebook page for more on the booth. Sometimes we just need inspiration and camaraderie. I hope we can help provide those things to you. Sincerely Donna Beth, a Co-Blogger of
