We know that replacing your internal door can sound like a complicated task. Our step-by-step guide will help you get it installed in no time. Whether you’re looking to change all your internal doors, or you just have a few that could do with a refresh, our buying guide is a great place to start if you don’t know what style to choose.


Measure the door opening or the existing door if it's a good fit, to ensure you get the right size door. Measure at three points horizontally and vertically taking the largest measurement to determine the correct width and height door to buy.

Different doors allow different amounts of trimming so if you can't buy the exact size, make sure you check the amount you can trim so that you can achieve the perfect fit.



  • Hold the new door in the frame to see if it needs adjustment.
  • A well fitted door should have a 2mm gap on either side and at the top. The gap at the bottom will depend on the thickness of your flooring/carpet.
  • Plane the door as required, using an electric plane will help you get an even finish, and sand for a smooth finish.
  • Where existing frames aren't square, this can make it more difficult. Buying a doorset which comes with the door already hung in its frame can reduce problems and the time taken to fit the door, ensuring a better finish.


  • Check new hinges fit the old ones in the frame. If not, mark on where new ones will sit and chisel away the extra wood.
  • Screw each hinge in place with one (centre) screw. The hinge knuckle should stick out from the frame edge.
  • Prop the door in the door frame using wedges to ensure correct gap at the bottom.
  • Mark where the top and bottom of the hinges sit on the door.

NOTE: Moulded, real wood veneer, foil, hardboard and MDF hollowcore doors should have 2 hinges. Feature and primed doors should have 3 hinges.


  • Unscrew hinges and lay them on the edge of the door, lining up with the pencil marks. Draw around the hinge.
  • Chisel out the middle to the same depth as hinge flap.
  • Check hinge fits flush and fix with one (centre) screw per hinge.


Support the door on wedges and fix hinge flaps to the door frame. Ensure the door opens and closes smoothly and finish fixing with all screws.


  • Where there is an existing keep, measure the distance from the floor to mark on the door where the latch needs to sit.
  • Hold the latch against the drill bit and mark the depth of the latch on the drill bit using masking tape. Drill into the door to the depth indicated by the tape.
  • Chisel out any remaining debris.
  • Insert the latch and pencil round the outside. Chisel out the recess so that the latch sits flush.
  • Hold the latch in position, but on the outside of the door. Put your pencil through the hole and make a mark. This is where the handle spindle will go. Make sure you mark this on both sides.
  • Drill the hole for the handle spindle.
  • Insert the latch and fix into place.
  • Insert the spindle through the hole and screw the door handle into place.


We pass through doors several times a day and scarcely stop to give them a second thought; this is especially so of internal doors. However, internal and external doors send out a message – they can look either welcoming or forbidding, well-maintained or neglected – and this tells people something about the occupants of the building.

This is why it’s important to keep doors looking good and in good repair, so they function well and look friendly. Just think – what’s one of the creepiest sound effects in a horror film? That’s right, the creaking door…

The style of door also says something – solid oak suggests conservatism and trustworthiness, whereas a sliding door, or a frosted glass door, suggests a more modern ethos.

Whatever style of door you opt for, you need to take good care of it so it lasts for a long time. You’ll probably get specific maintenance advice, but in general, most doors need a similar care regime.
