As with any other DIY task, you’re going to have to assemble all the necessary tools and materials first.

Here’s what you’re going to need:

  • Internal door frame kit
  • Saw
  • Screwdriver
  • Drill
  • Screws
  • Hammer
  • Chisel
  • Level
  • Measuring tape
  • Pencil
  • Wood glue
  • Sandpaper

And here are the steps you’ll need to follow:

Step 1: Measure the opening

Before you begin, you need to ensure you have the right size door frame for your opening. Measure the height and width of the doorway where you want to install the door frame. Make sure you measure the opening at its widest point, as this will ensure that the door frame fits snugly.

Step 2: Assemble the frame

Next, assemble the door frame according to the manufacturer’s instructions. Read the instructions carefully and follow them to the letter, as the specific process tends to vary slightly from brand to brand. Most internal door frame kits come with pre-cut pieces that fit together like a jigsaw puzzle. Use screws to secure the jambs in place.

Step 3: Trim the head

If the headpiece doesn’t fit into the opening, you’ll need to trim it on either side. Leave some room around the frame so you can make slight adjustments once it’s in the opening.

Step 4: Position the frame

Once the frame is fully assembled, place it in the doorway. Use a spirit level to ensure that the frame is perfectly vertical and horizontal. If the frame is not level, adjust it until it is.

Step 5: Secure the frame

Once you have the frame in position, secure it to the wall using screws. The type of screws you need to use will vary depending on the type of wall you have.

Drill pilot holes in the frame and then screw it into place. Make sure you use enough screws to secure the frame firmly in place.

Useful tips to keep in mind when fitting door frames

 

  • Always wear protective eyewear and gloves when working with tools.
  • If the door frame is not level, use shims to adjust it.
  • Make sure you drill pilot holes before screwing the frame into place to avoid splitting the wood.
  • If the door is sticking, adjust the hinges or use sandpaper to sand down the edges until it fits smoothly.
  • Always follow the manufacturer’s instructions when assembling the door frame.
