How to Fit an External Door in 12 Simple Steps

When fitting an external door, you have two different scenarios. You may be cutting into an existing wall for a brand-new entrance, or simply replacing a door that has already been framed in. There’s a lot more work involved when creating a new entrance, rather than upgrading an existing door, but we will take you through how to do both.

When you’re creating a new entrance on a blank wall, you have to ensure that you maintain structural integrity. Follow these steps in order to install a front door properly:

  1. Gather the necessary tools and materials
  2. Determine the door size and rough opening
  3. Mark the rough opening on the wall
  4. Remove any existing wall covering
  5. Cut the wall studs and header
  6. Install the header
  7. Frame the sides and bottom of the rough opening
  8. Check for plumb and level
  9. Secure the frame
  10. Check for proper clearance
  11. Install any required additional framing components
  12. Insulate and install the door

1. Gather Necessary Tools and Materials

You will need a tape measure, framing square, circular saw or reciprocating saw, hammer, nails or screws, framing lumber, shims, and a level.

2. Determine the Door Size and Rough Opening

Measure the width and height of the door you intend to install. The rough opening should be slightly larger than the door size to allow space for framing, shimming, and adjustments.

3. Mark the Rough Opening on the Wall

Use a pencil to mark the dimensions of the rough opening on the wall, ensuring it is plumb and level.

4. Remove Any Existing Wall Covering

If there is drywall or other wall covering in the area where the door will be framed, carefully remove it to expose the studs.

5. Cut the Wall Studs and Header

Determine the desired height of the rough opening and cut the existing wall studs accordingly using a saw. Next, cut two horizontal header pieces using the appropriate dimensions and material.

6. Install the Header

Position the header above the rough opening and secure it to the existing studs using nails or screws. Ensure it is level and securely fastened.

7. Frame the Sides and Bottom of the Rough Opening

Cut two additional studs to the height of the rough opening and install them vertically on each side of the opening. Secure them to the existing studs and the header. Cut and install a bottom plate at the bottom of the rough opening, securely attaching it to the studs.

8. Check for Plumb and Level

Use a level to ensure that the sides, top, and bottom of the rough opening are plumb and level. Make any necessary adjustments by adding shims behind the studs.

9. Secure the Frame

Once the frame is level and plumb, secure the studs and header together with nails or screws. Ensure the frame is sturdy and well-anchored.

10. Check for Proper Clearance

Verify that the rough opening provides enough clearance for the door to open and close freely without rubbing against the frame. Adjust the frame or shim as needed to achieve the proper clearance.

11. Install Any Required Additional Framing Components

Depending on the door type and installation requirements, you may need to add additional framing components such as cripple studs, jack studs, or a sill plate. Follow the specific instructions for your door type.

12. Insulate and Install the Door

Once the framing is complete, you can insulate the surrounding areas if desired. Then, follow the manufacturer’s instructions to install the door slab, including attaching it to the frame with hinges and installing any necessary hardware.

If you’re replacing an existing door, you cut down the steps drastically. Before you buy front doors, be sure to follow steps 1 and 2. You need to be sure that your new front door fits into the existing space. Once you have your door, then you can skip to steps 9 through 12.

Top Tips When Fitting Your External Door

Hanging a door frame can sometimes present challenges or unexpected issues. Here are some troubleshooting tips to help you address common problems that may arise during the process:

Uneven or Out-Of-Square Rough Opening

If the rough opening is not perfectly square or level, it can make the door frame installation more challenging. Use shims strategically to adjust and level the frame as needed. Place shims behind the hinge and latch-side jambs to create a plumb and square installation.

Sticking or Rubbing Door

If the door sticks or rubs against the frame when opening or closing, it may indicate a misalignment. Check the hinge-side gap to ensure it is consistent along the entire height of the door. If necessary, adjust the position of the hinges or shims to ensure the door swings freely.

Gap Between the Door and Frame

Gaps between the door and frame can compromise energy efficiency and security. Adjust the shims or hinge positions to minimize gaps as much as possible. To address gaps further, use weatherstripping or door seals to fill the gaps and improve insulation. You can also use add-ons or wood, which come in very handy if your door is a few centimetres smaller than your opening. Since trim will cover the extra wood, no one will even notice.

Misaligned Latch or Strike Plate

If the latch doesn’t properly engage with the strike plate or the door doesn’t latch securely, you may need to adjust the position of the strike plate. Use a chisel to enlarge the recess or move the strike plate slightly to align it with the latch.
