Why Trim a Door for Carpet

There are many reasons for wanting to trim a door for carpet. Perhaps you noticed that it looked like this when you first moved into your place and just never fixed it, or maybe you just recently noticed the issue yourself. Either way, this guide is going to show you how easy it is to fix so that you won’t be bothered by the problem again. 

Materials You Needs

  • Razor Blade (Preferably retractable like this one )
  • Tape Measure (Preferably the Flexible Measuring Tool )
  • Level (Preferably a Black Leveling Tool )
  • Pencil or Sharpie
  • Utility Knife with New Blades

Steps On How to Trim a Door for Carpet:

Step 1: Pencil  Measure the Width of Your Door

  • Use your tape measure to find out how wide your door is. Write it down (using a sharpie or pencil) on the back of your door. For example, let’s say that you find out that your door is approximately 22″ wide. That would mean if you want everything to line up nicely that you need to have a piece of carpet that is roughly 22″ wide. Also, if your door is stained or painted, remember to include the width of any molding around the edge as well. 

Step 2: Measure Your Starting Point from the Top and Bottom Edges

  • Look at both ends of your door and find out how far down from the top your carpet needs to start. Then, take that number and subtract it by how wide your door is. So let’s say that you find out that for the bottom edge of the carpet to line up with the edge of your door properly, it needs to be around four 5/8″ from the bottom of your door, and your door is 22″ wide. That means that you should start the padding 4 5/8″ from the bottom of your door. Then do the same for finding out where to start it from the top, but you would add how wide your door is to this number instead of subtracting it like you did in step 1.

Step 3: Remove the Door Stop Molding (if it’s needed)

  • If you find out in step 1 that you need to remove more than 1/8″ on either side, then you will need to remove some of your doorstop moldings. Do this by using a razor blade and carefully cutting along the molding until you can easily pry it off (see picture below). This will not need to be done if you only decided to remove less than 1/8″.

Step 4: Remove the Door Knob or Handle Set

  • If your door is still locked, then unlock it, and then take out all of the screws that hold the knob or handle set in place. You should see something like the picture below when it is completely taken out.

Step 5: Measure How Much Edging You Need to Take off Your Top Molding

  • Use your tape measure and measure how much you need to remove from the top molding by following how wide your door is (22″). For example, let’s say that you find out that you need to remove 1″ from the molding. If your door is stained or painted, remember to include the width of any molding around the edge as well.

Step 6: Mark Where You Need to Cut

  • Once all of these measurements have been found, it’s time to make the measurements for your door itself. First, take out your tape measure and find exactly where to start marking with a sharpie or pencil (whichever you prefer). Then, use your level to make sure that everything will be straight (see picture below).
  • Once you have marked where to cut over both edges, take out your razor blade or utility knife and cut along the marks you made on your door. Try to make your cuts as clean as possible, but don’t worry too much if they are a little jagged because you will be covering them up later with the carpet padding anyways.

Step 7:  Cut Your Edging for the Door Stop Molding

  • Here comes the messy part. First, take your doorknob or handle set and cut around it about an inch in so that you can take it out without messing up too much of your carpet padding. Please do this by using your utility knife, making very careful but firm cuts until you can pry it off the door. Once it’s completely removed, take a look at your carpet padding and see how much you need to remove from around the edge of the molding (see photo below).

Step 8: Cut Off Your Door Padding

  • Use your utility knife again to remove enough padding so that it starts at exactly where you measured for in the previous step. If the padding is too thick for you to cut through easily, then just score it a few times with your utility knife until enough of the carpet comes up so that you can tear some off (see picture below).

Step 9: Put the New Carpet Pad Down

  • Once you have cut enough of your door padding off, go ahead and unroll some of your new carpet pad. Then, put it face down on a flat surface and measure how much you will need to cover up where you measured for in step 7 (see picture below).
