Composite door installation should be taken out by a qualified fitter to ensure it is done correctly. The installation requires at least two people, as the weight of the front door can make it tricky to handle. You can also click here to hire a professional front door tester online.

If everything is present and correct, you can begin the process of removing the old front door. To begin with, run a knife around the outside of the old door frame, both inside and outside. Next, remove the old front door from its frame.
If your new front door comes with a sill, you need to do some measuring and cutting. The sill provided is often bigger so that you can create a sill horn if you want. Measure the width of the doorway as well as the distance between the outside brick and the inner plasterwork.
Next, carefully copy these measurements onto the sill and cut away the excess. Squeeze a layer of silicone along the bottom of the doorway and apply the sill, ensuring it is level.
Before installing the new front door, first, attach the handle, then remove the protective tape from the inside of the door only. Position the new door in the open doorway, using packers between the frame and bricks to ensure stability. When it is stable, open the door in the frame and support using bricks.
Using frame fixing screws, screw the frame to the wall, making sure not to overtighten which may damage the frame. Do the same on the opposite side of the frame. Next, chisel off the excess of the frame packers.
