How to replace cavity sliding door furniture?

[Bell_xo]

Hello Living in my new build home nearly three years now.... pretty standard so im changing things here and there... I have three cavity sliding doors two which lead in to the pantry and laundry and one that leads to the garage. I changed the door handle on the cavity sliding door leading the the garage to a lock one which unfortunately rattles and is very annoying although it does lock successfully keeping the dogs from getting into the garage. The handle also has a turn thing that could potentially cause more damage. Due to this and my installation I am planning on changing the lock mechanism and replacing the door at some stage. Regards the two other sliding cavity doors appears the piece that knocks to the wall is unnecessary and has only caused damage so I have taken this part out. I would very much appreciate guidance on how I could fill this area and also a good suitable locking mechanism for the door that leads to the garage. Please see pics. I am hoping I can get this sorted so does not look messy and falling apart! Thank you

Hi @Bell_xo,

Welcome to the Bunnings Workshop community, it is fantastic to have you with us.

The unfortunate reality with cavity doors is that, because they require clearance to slide, their associated hardware is not made to the tightest tolerances, which can cause rattling at times. The lock you have already got is about as good as you can get for this style of door.

One thing you can do, assuming there is enough of a gap, is add a Moroday 6 x 7mm x 5m Black MWS8 Self-Adhesive Brush Seal on each side of the door pocket.

This would allow the door to roll freely while helping to dull the timber-on-timber sound caused by any rattling.

If the rattling is from the metal of the lock, if space permits, you could try adding something like a Surface Gard 10mm Clear Round Rubber Bumper inside the cavity in the striker plate.

To fill the hole from the unused parts, you can use Turbo Builder's Bog, which is a two-part filler that will set hard as timber. You can apply it to the hole, allow it to dry, give it a sand, then paint it.

Let me know what you think and if you have further questions, please don't hesitate to ask.
