Tools and Materials You’ll Need

- Electric drill with hammer action and suitable bits
- Plastic-sheathed frame fixing screws (minimum size 8x100mm)
- Silicone sealant and applicator gun
- Hammer, chisel, saw, and rubber mallet
- Safety gear (gloves, goggles)
This toolkit, recommended in professional fitting guides, will help you complete the job efficiently and effectively.
Preparing the Door Opening
Proper preparation is crucial for a flawless installation. Follow these steps:
- Measure the Space:
- Accurately measure the width, height, and depth of the opening to ensure the new frame will fit.
- Remove the Old Frame:
- Use a craft knife to score around the old frame and minimise damage to surrounding plaster.
- Cut through the jambs diagonally and remove the frame in sections, ensuring no damage to internal reveals.
- Clean the Opening:
- Clear out screws, nails, and old mastic. Repair any damaged areas with filler and ensure the structure is solid.
- Check for a structural lintel above the opening, as this supports the wall above the door.
How to Build and Fit a Door Frame: Step-by-Step Guide
1. Position the Frame
- Place the frame in the opening, ensuring it’s square and plumb in all planes. Use packers to adjust and stabilise the frame.
2. Mark Fixing Points
- Mark fixing points 150mm–250mm from each corner and no more than 600mm apart for intermediate fixings. For frames with transoms, position fixings 150mm–250mm from the transom centreline.

3. Align the Frame
- Double-check alignment with a spirit level. Adjust packers as needed to keep the frame square.
4. Drill and Secure
- Drill holes into the brickwork (not mortar) at the marked positions. Next, insert and tighten plastic-sheathed fixing screws to secure the frame, taking care not to over-tighten and distort the frame.
5. Seal the Perimeter
- Apply silicone sealant around the frame’s perimeter for weatherproofing and to prevent drafts or water ingress.

How to secure a door frame to a wall?
Secure the frame with plastic-sheathed fixing screws drilled into solid masonry, not mortar. Ensure packers are placed near fixing points to prevent frame distortion.
