Good morning everyone.
A few months ago I registered here in the forum because I had a question regarding a house we wanted to buy.
Now we have bought it and moved in about 2 weeks ago. Now I have to say: there is still quite a lot to do.
First, I would like to start with the windows. There is a draft throughout the whole house.
The house was built in 1998, and the double-glazed windows are also from that year. The house is completely brick-faced. When I look at the transition from the brick facing to the plastic windows, there is a gap. On the right and left in this gap, a black foam is visible. The bottom edge is completely “open,” so you can still see the wooden blocks used as spacers during installation.
I actually expected that these areas would be sealed with silicone and would now like to fix that. However, I am unsure because people have been living in this house for 18 years. Maybe this gap is also supposed to be there?!
Can someone give me a tip? That would be great. I can also upload a photo if needed.
Thanks in advance
Best regards
Mika

Yes, go ahead and take a photo.

Silicone is definitely not what is needed, it is unsuitable for that.

Thank you for the response. I thought construction silicone would be suitable? When I look at other houses (while driving by), they always have a white strip there that doesn't look like a molding, but rather like a rubber joint due to its "irregularity." Here are a few example pictures. Best regards Mika

So on the sides we have foam rubber strips - Kompriband. At the top and bottom it is sealed with rubber compound (silicone?).

Normally, compressible tape and a fleece are used on the outside – as is common with us and according to RAL guidelines.

In a 90s house, sealing compound was usually used, and that worked as long as you renewed the compound eventually.

Of course, it’s annoying that the block is visible... normally, the blocks are not visible from the outside. If you really want to, you can do it with suitable sealing compound, but it has worked fine so far.

Nowadays, new buildings usually no longer use something like that...

Thank you for the answers. Well.. what does it mean to want it urgently.... I would like the house to be a bit less drafty.. I have the feeling that wind is coming in everywhere or through. In my feeling, the gap under the window could be a weak point (also when it rains)... Therefore, I would like to seal it. On the sides, I see it more as an aesthetic measure. Based on your answers, I would say it is correct and normal... Would it be wrong to seal the windows (except at the top, of course) with BauSilikon? Best regards and have a nice rest of Sunday. Mika
