ᐅ Flexible Joint Sealants – What Are They and Who Has Experience With Them?

In the cost breakdown provided by our construction manager, there is an item called "elastic joints" listed at around 700€. I had asked about it before, but I don’t remember: what kind of joints are these? I couldn’t find any clear information online, only companies offering these services without specifying where these joints are located. So – could someone please clarify which joints these are?

Silicone joints at the transition between either floors and their baseboards or ceilings and walls on the upper floor.

Could be bathrooms, but also door frames. Possibly also on stairs.

aha... hmm, actually I would have expected that a joint between the floor screed and the floor strip would be included in the flooring contractor’s offer.
In the bathroom, there are still some vertical joints missing in the corner between tile and wall. And we don’t have door frames yet, so I also thought the door specialist would take care of those.

So, in conclusion: I understand that there are still joints in various places – but I had assumed these belong to the respective trades and aren’t handled as a separate task by some other trade?
Alright, then we’ll see...

The interior contractor handles the areas between the walls, while the tile baseboards are provided by the tiler. There is often some splatter, which is the technical term used by professionals. That is probably why there is a separate item for it. These should ideally only be done after about 2 years, once everything has settled.

You should wait at least 2 years before doing that, to let everything settle.

I can only recommend that. Many of the joints cracked in the first few years because we did it right away. I removed the silicone and re-caulked. Applying the new sealant is manageable, but removing the old silicone can be really tricky. Depending on the joint size, I have now inserted a backer rod. This saves silicone in large joints and should make removal easier next time.
