Change which way a door opens — HomeGraft

Rehang a door to swap its hinge side or swing direction in one session, with the right wall fixing for your frame.

AB-01Plan the new swing directionDecide whether you're mirroring the hinges to the other edge of the same opening, or flipping the door to open into the other room. Check the new swing won't hit a light switch, radiator or another door, and measure for an even 2-3mm gap at the top and hinge side, 3-4mm at the closing edge. Note exactly where the hinges, lock and handles sit now so you can mirror them precisely later.

KNOW THE RULES

If this is a flat entrance door, a door onto an integral garage, or any fire door, Building Regulations require it to open in the direction of escape and keep its fire-rated hinges, seals and closer. Check before you change how it swings.

AB-02Protect the area and gather toolsLay a dust sheet under and around the door and remove any rugs. Get everything ready: drill/driver, wood and masonry bits, chisel, mallet, screwdriver, combination square and wood filler. Doors are heavy and awkward on your own, so line up a helper for lifting it off and on.

AB-03Check for cables and pipes, then find out what's behind the frameBefore any drilling, find your stopcock (usually under the kitchen sink) and check it turns, so you can shut the water off fast if you hit a pipe. Cables and pipes can run almost anywhere in a wall, not just the usual zones, and a detector misses deep cables, metal conduit and anything behind metal-backed board — treat every hole as if something could be there. If in doubt, isolate the circuit at the consumer unit first. Now work out the wall type behind the lining: run a detector or magnet up the architrave line looking for fixing screws, tap either side of the frame for a hollow (stud) or dead (masonry) sound, and drill a small 3mm test hole near the top of the reveal — reddish or grey dust means brick or block, timber dust means a stud, fine metal swarf means a metal stud, and a hard skim followed by a gap then something solid means dot-and-dab over masonry. Lath and plaster feels springy and shows thin timber laths in the hole.

KNOW THE RULES

Part P of the Building Regulations covers fixed electrical work. Drilling itself isn't notifiable, but if you damage a cable and need repairs or alterations, that work should be done or checked by a competent electrician.

AB-04Take the door off its hingesWedge the door open and have your helper support its weight. Undo the bottom hinge first, then the top, keeping a hand under the door as it comes free. Lift it clear and lay it flat on trestles or a folded blanket to protect the floor.

AB-05Strip the old hinges, lock and handlesUnscrew the hinges from both the door and frame, and remove the lock or latch and handles. Using a combination square, mark the mirrored positions on the opposite edge of the door and frame, copying the exact distances from top, bottom and handle height.

AB-06Fill the old recessesFill the old hinge recesses, lock mortice and screw holes on both the door and frame with wood filler, slightly proud of the surface. Leave it to cure fully before cutting anything nearby, usually 20-30 minutes.

AB-07Cut the new hinge morticesMark the hinge outlines on the new edge of the door and the matching heights on the frame, using the old positions mirrored across. Score the lines with a knife, then chisel a series of shallow cuts to the hinge-leaf depth (usually 2-3mm) and pare the waste flat. Repeat on the frame.

AB-08Fit the new hinges and rehang the doorScrew the hinge leaves to the door edge first, using one screw each to test the fit. With the door supported on packers for an even 2-3mm gap, mark and drill pilot holes on the frame leaves, then screw the door in place. Add the remaining screws once you're happy with how it hangs.

AB-09Move the lock or latch to the new edgeMark the spindle and forend positions to mirror the old side, drill the spindle hole, and chisel a mortice for the lock or latch body. Most modern latches are reversible without new parts; older rim locks may need a new one for the correct handing. Cut a matching mortice on the frame for the new strike plate and screw it flush.

AB-10Fix the hinge side of the frame properly for your wall typeThe hinges now carry the full weight of the door on this side, so the lining needs a solid fixing into the wall, not just the plaster. Check again for cables near the fixing point, especially close to any light switch or socket. Solid brick or block: drill a 7mm masonry hole through the lining, fit a wall plug, and drive a 60mm countersunk screw home. Timber stud: drill a 3mm pilot hole and drive a 60mm woodscrew into the centre of the stud. Metal stud: most stud-wall openings have a timber liner built in behind the lining for exactly this reason — fix into that timber, not the bare steel. A door pulls on its hinge fixings every time it's opened, so if there's no timber liner, don't rely on the metal stud alone; get a timber noggin fitted between the studs first, or fix through to masonry if there's any behind. Dot-and-dab: use a 90-100mm fixing long enough to pass through the board and the dab void and bite into the masonry behind — a standard plug and screw won't reach. Lath and plaster: locate the timber studs behind the laths (roughly every 400mm) and screw into these with a 65-70mm screw, pre-drilling to avoid cracking the old plaster.

AB-11Move the door stop if the door now closes the other wayIf you've just mirrored the hinges within the same opening, the doorstop usually doesn't need to move, as standard linings are symmetrical. If the door now opens into the other room, unpin the old doorstop, refit it on the opposite face, and fill and touch up the old pin holes.

AB-12Refit handles and rosesFeed the spindle through and refit the handles on both faces, tightening the grub screws. Fit any escutcheons or keeps that were removed earlier. If your handles are a handed design, you may need a new set for the correct orientation.

AB-13Test the swing and fine-tuneOpen and close the door several times, checking for an even gap all round. If it binds at the top or bottom, deepen the relevant hinge recess slightly with a chisel. If it doesn't latch cleanly, loosen the strike plate and shift it by a millimetre or two.

AB-14Fill, sand and touch upFill any remaining screw holes or gaps, let it cure, then sand flush and wipe away dust. Touch up paint or varnish on the door edge and frame to match the rest.
