Step-by-Step Guide
Step 1: Measure the opening
Check the width, height and depth of the opening at several points. Make sure the new door and frame will fit with enough room for adjustments.
Step 2: Prepare the opening
Remove the old door and frame if needed, then clear away debris, old sealant and loose plaster. The opening should be sound, square and ready for the new frame.
Step 3: Position the frame
Lift the frame into place and use packers to hold it level and plumb. Check both sides and the top before fixing anything permanently.
Step 4: Fix and check alignment
Secure the frame with screws, checking alignment as you go. Open and close the door to make sure it swings smoothly and seals evenly.
Step 5: Seal and finish
Apply suitable sealant around the frame to keep out draughts and water. Fit trims or finishing pieces once everything is secure and working well.
- Get a helper for lifting and holding the frame.
- Check the door swings the right way before fixing.
- Use packers to prevent twisting.
- Test locks and latches before finishing the sealant.
Composite doors are heavy, so take care when lifting and support the frame properly to avoid injury or damage.
Final Thoughts
A well-fitted composite door should close cleanly and feel solid. Careful measuring and steady fixing are the keys to a good result.
