How to extend the height of an internal door?

[Noyade]

I'm wanting to extend the height of a new hollow internal door. Distance and width below. When the photos were taken - it's just sitting on the floor with no clearance yet. I have an assortment of tools including a thicknesser - but I'm hoping not to have to use it.

Also - how to hang a door videos would be appreciated.  👍

Cheers!

Hi @Noyade 

I nominate the 70 x 35mm 0.9m Short Pine Run Of Mill to be attached to the bottom of the door. I would say that the bottom of the door is not as visually noticeable as the top of the door when being opened. 

This is the closest piece of timber I could find that meets the measurements that you need. It will still need to be trimmed, but you won't need to take too much off.

I suggest timber glue along with Zenith 10G x 75mm Countersunk Rib Head Chipboard Screws - 14 Pack. I recommend Parfix 500g Ready To Use Multipurpose Filler or similar to seal the joint. Please don't forget to drill pilot holes to prevent splitting the patch and door frame.

Here is a handy step by step guide: How to hang a door

If you need further assistance, please let me know.

Thanks @EricL 

Much appreciated! I never thought of the bottom of the door. 🤔 Excellent idea.

Cheers!

Afternoon @EricL 

Thanks for the wood tip - the size worked a treat. I don't know why, but I had thoughts of having to wander around the wood section looking for dressed hardwood to fit.

I just ripped it to size and length. With a poor shoulder, I found it easier to space the bottom of the door and work upwards, so I will now need to instruct anyone who enters the house to keep their eyes to the floor. 😁

Great work @Noyade! Thanks for sharing your results.

I now need to make a 'fake' door jamb. I want all this to be removed at a later date - call it a temporary bedroom door/wall encasing an old living room area entrance.

If you took a cross-section of a typical internal door jamb - what would it look like?

Cheers.

There are a couple of different styles @Noyade. One's a solid rebated piece of timber and the other has a stop trim piece nailed on.

Thanks @MitchellMc 

I'm gonna try making your profile seen on the left, but outta inexpensive pine. I don't expect a perfect finish to paint - but what filler do you recommend for the glued spaces and wood irregularities?

Cheers.

A couple of doodles of how I'm filling in an opening with a 'fake' wall and door.

Hopefully to be taken down at a later date.

I'm gonna try this. Never seen a powder form before. I live a sheltered life.

Hi @Noyade 

Just a friendly reminder not to add too much water. Keep us in the loop and tell us how it performs.
