ᐅ House built in the 1960s – Should the interior plaster be left as is or completely removed?

Opinions on this differ widely. I have already had 2-3 craftsmen in the house; one argued that it makes sense to renew all the interior plaster, while the others said it would be a waste of time and money since it is completely unnecessary if the interior plaster, although 60 years old, is still in good condition. What is the common opinion?

Why do you want to renew the plaster? What other renovations are planned?

I have gutted the entire house. Ultimately, the goal is to reach KFW 70 standard.
- new roof
- new insulation
- ventilation system
- new heating (heat pump / underfloor heating)
- ...
(the list is practically endless and has already been detailed in several forum posts.)

For me, the question is why some experts recommend removing all the interior plaster, even when it still adheres well and has been dry. In the former kitchens and wet rooms, I followed that advice, as I didn’t want to take any health risks there.

To generate jobs and income.

In that case, I would leave it in place as well.

Even here, the plaster would still have been usable.

I have never had plaster replaced during renovations in any of my properties. Even in my owner-occupied home, the plaster from the 1960s is still in place.

If the plaster looks fine, I would leave it as is.

On the other hand, you mentioned stripping the interior. That makes me think of rewiring the electrical and plumbing systems to bring them up to current standards, as well as adding a network. If there has been a lot of chasing for these updates, then considering new plaster might be a good idea.

Yes, the electrical and plumbing are also completely removed and need to be reinstalled. The amount of chasing was limited, so leaving the plaster should be fine.

My main concern was whether it makes sense, since the house – and the plaster – are already quite old.
