How to fit a door closer

Video by Charlie DIYte. This walk-through is based on the video "THROW AWAY THE INSTRUCTIONS! How To Fit A Concealed Door Closer" from Charlie DIYte, who works through the whole fitting in a refreshingly honest way — including why the supplied instructions are often more confusing than helpful. Worth watching before you pick up a drill, particularly the bit where he positions the arm bracket on the frame.

1. Choose the right type of closer for your door

There are two types you are likely to deal with in a typical British home. The overhead closer — a rectangular unit that mounts on the face of the door and frame — is the most common and the easiest to fit. The concealed closer sits inside a routed slot in the door edge and frame rebate, so it is invisible when the door is shut. It looks a lot neater but takes a bit more care to install.

For most internal doors in a semi-detached or terraced house, either works well. That said, if the door opens onto a hallway and you want a tidy finish, concealed is worth the extra effort. Check the weight and width of your door first — most residential closers are rated for doors up to around 80 kg and 1,100 mm wide. Anything heavier needs a higher-rated unit.

2. Mark up the door and frame carefully

Most closer kits include a paper template. Before you even think about drilling, fold it and position it as directed — usually with the door at 90 degrees open, so the arm lines up correctly with the pivot point on the frame. Tape the template in place, then use a sharp pencil or bradawl to mark every hole through the printed circles.

Double-check which side of the door the closer sits on. On a standard push-side installation the body goes on the door face; on a pull-side installation it goes on the frame. Getting this wrong means your fixing holes end up in the wrong place entirely. To be fair, it is an easy mistake to make if you just dive straight in without reading through the positions first.

3. Drill the fixing holes cleanly

Use a sharp wood bit at the correct size — the kit instructions will specify, but it is usually 3 mm for pilot holes in softwood. Drill squarely; an angled hole means the screw will pull the mounting plate off true. If you are fixing into a hardwood door or a composite door with a steel core, you may need a slightly longer screw or a metal-rated bit.

For a concealed closer, you will also need a chisel and mallet (or a router if you have one) to cut the rebate for the closer body. Work to the depth marked on the template — too shallow and the door will not close fully; too deep and the arm will not engage properly. Take your time here; a clean rebate makes the rest of the job straightforward.

4. Fit the closer body and the arm bracket

Screw the closer body to the door first, then the arm bracket (also called the shoe or pivot block) to the frame. Do not fully tighten anything yet — leave the screws just slightly loose so you can adjust the position once the arm is connected. The arm needs to sit level when the door is in the closed position; if it angles upward or downward the closer will drag or pop open.

On an overhead closer, connect the arm to the body by pushing the pin through the pivot hole and clipping or threading the arm onto the frame bracket. On a concealed closer, the arm simply slides into the slot in the frame plate. In both cases, once everything looks aligned, go back and tighten all the screws fully.

5. Adjust the closing speed and latch action

Most closers have two adjustment screws in the body, usually accessible with a small flathead or hex key. The first controls the main closing sweep — how fast the door travels from fully open to about 15 degrees from shut. The second controls the latch speed — the final snap that seats the latch in the strike plate.

Turn the main sweep screw clockwise to slow the door down, anti-clockwise to speed it up. Start in the middle and test a few times before fine-tuning. The latch speed should be just enough to click the latch home reliably; set it too fast and the door will slam at the end of its travel, which defeats the whole point. Mind you, in a windy East Kent hallway you may want a little more latch tension than you would in a sheltered room.

6. Test the door thoroughly and make final checks

Open the door fully and let it go. Watch how it moves through the whole arc — it should swing smoothly and slow noticeably in the last 20 degrees before the latch clicks home. Push it open at different speeds to check it does not bounce back off the frame or stall before it latches.

Check all fixing screws one final time. It is worth coming back 24 hours later and giving them another quarter-turn, as wood can compress slightly once the closer has been used a few times. If the door starts to squeak or drag after a few weeks, a small drop of oil on the arm pivot point usually sorts it.

When to call a handyman

Call Richard if the door is badly warped or dropping on its hinges and will not close cleanly even without a closer, or if you need a fire door closer fitted to meet building regulations — those need to be certified units and they need fitting correctly. Composite and steel doors with tricky cores can also be awkward to drill without the right bits; if you are not confident, it is worth getting someone in rather than making a mess of the face of an expensive door.
