Easy Doorway Makeover in 9 Simple Steps

Spruce up the house after a paint job or add the finishing touch to a renovation by hanging new internal doors.

Easy Doorway Makeover

There are lots of reasons you may need to hang a new internal door at your place.

A major renovation can change the layout of a home while building an extension can add doorways, creating the need for new doors.

Replacing old or mismatched doors is also an easy and affordable way to instantly refresh interior spaces, particularly if you’re painting walls or updating floors.

Hanging a new door, including the jamb and hardware, is a simple DIY project that can be completed in just one day.

And doors can be purchased in kit form with a jamb that already has the hinge housings.

Jambs and doors can also be bought separately, offering a greater variety of sizes and styles.

If you’re installing a new jamb as well as a door, you will need to check the doorway studs for plumb, then measure the size of the opening to determine the door size.

For this project, we installed a 2040 x 820 x 35mm hollow-core door and separate 92 x 30mm jamb.

Hollow-core internal doors have additional blocking inside one edge, identified by a sticker that marks where the lockset should be installed.

1. Make the jamb

Cut two stiles equal to the height of the door, plus 20mm clearance, and a head piece the width of the door, plus 46mm for two gaps and two stiles.

Cut a housing to the rebate depth at each end of the head.

Chisel out the waste

Mark hinge locations on the door, 200mm from the top and 250mm from the base.

Transfer the locations to the stile, tracing around a hinge to mark each recess.

Use a combination square to mark the depth of the recess.

Mark the hinge recesses on the edge of the door 2mm narrower than on the jamb to stop the door from binding on the jamb.

Use a sharp chisel to make relief cuts to the depth of each recess, then pare out the waste.

With the hinge in the door recess, drill a pilot hole towards the back of the hinge hole so the screw will pull the leaf tightly into the recess.

Secure the hinge with a screw, check the clearance, then drive in the remaining screws.

On a pair of level sawhorses, assemble the jamb around the door and drill clearance holes through the head.

Drill pilot holes into the stile ends and secure with screws, then check that the door opens smoothly.

Secure packers in the opening at the hinge locations, and equally spaced above and below, to correct for any studs that are out of plumb.

Use a long spirit level to check for alignment and to ensure the top gap is consistent.

Position the jamb and align the hinge side with the wall cladding.

Drive a single nail at the top packer, using a spirit level to plumb the jamb.

Secure with nails through the packers, punching the heads below the surface.

Align the lock side of the jamb, using wedges to create a 3mm gap around the door.

Attach the jamb with one nail, then close the door and check the gap.

Move the wedges in or out to adjust, then secure the jamb with nails

9. Add the architrave

Set the architrave 5mm back from the inside jamb face.

Cut left and right architraves with mitred tops, securing with brads.

Mark the head piece from the gap and cut to size, attaching with PVA adhesive and brads.
