ᐅ Is it possible to shorten a plastic door?

Hello everyone,

In the next few days, we plan to install a new vinyl floor over our tiles. For this, we first need to apply a leveling compound (2 mm [0.08 inches]) and then lay impact sound insulation and click vinyl. Unfortunately, our plastic door leading to a covered outdoor area will no longer fit after that. It is an older door, and I haven’t seen any way to raise the door frame (there is space above).

This has led me to wonder whether I can shorten the bottom of the door a bit (see photo)? Unless there is a way to raise the door? The appearance is less important for now, as we will eventually replace the door anyway (which is postponed for time and budget reasons).

Many thanks in advance.

Best regards
Daniel Kraft

What speaks against milling the screed in this area? It is definitely possible, and you could create a slope towards the door.

At the door, you can remove at most 3-4mm (0.1-0.15 inches); beyond that, the seal is reached, and drafts will start.

I don’t quite understand, tiles have been laid everywhere, right? Nothing can be done about the door?

Did I read correctly that you want to lay the vinyl flooring on top of the tiles?
In that case, the solution would be to knock out the tiles to gain some extra space. This requires some effort but hardly any cost.
If the door frame has some clearance (measure to be sure), it might be possible to lift the door slightly. For some hinges, this is not designed and can be quite tricky. Shortening the door will likely affect its sealing.

Yes, exactly, leveling compound should be applied to the tiles, about 2mm (0.08 inches), and then the vinyl flooring on top.
