Hello,
I’m usually a silent reader since I do a lot of work on our house myself.
A bit about me: I’m 28 years old and bought a bungalow of 74 m² (800 sq ft) about 1 1/2 years ago. This year, the old aluminum windows had to be replaced because they were letting in a lot of cold air.
Anyway, based on a colleague’s recommendation, I chose a window installer who mainly works on new builds, just like with my colleague.
Putting aside the work attitude of the tradesmen, I just wanted to ask if this is normal. For your information, they didn’t meet their schedule and will come back in the next few days to install the patio door and to complete the trim, sealing, and insulation of the roller shutter box, which they simply forgot until I mentioned that it was supposed to be insulated. This is contractually agreed upon.

Here, specifically the connection at the window sill, are they probably sealed tight with trim strips?
And just now I noticed that in this case, the trim strips at the window sill are already coming off, which would theoretically allow water to enter freely.
Here, the exterior trim strip is also slightly detached, so I looked inside directly—it’s possible to see up to the inner trim strip, indicating poor foam sealing? Who knows how the others look underneath.
Please don’t be too harsh, this is a professional company—a self-employed master carpenter. Since the windows were replaced in an old building, no sealing tape was used inside or outside. Outside they rely on weatherproofing with trim strips plus additional silicone? And the same inside?

I think it will be "visually sealed," with trim and lots of silicone. Not much more is to be expected.
I hope no standing water will accumulate in front of the window.

I have a question where I could use some advice.
Yesterday, the team finally came back and completed the remaining work, including installing the trim and sealing.
The guys were about to finish for the day, and I pointed out some foam sealant on two windows. They tried scraping it off roughly with a utility knife and measuring tape, but since it didn’t come off completely, they used some kind of cleaner. One of them mentioned that if too much cleaner is used, the white residue might show later.
He said he was done, but some residue was still visible, so he kept scrubbing. The final result looks like this.
See attachment.
You can clearly see how smoothly the area was scrubbed, and how deeply the foam sealant soaked in—it has been on the window for 4 weeks.
The same issue is present on a basement window.
The supervisor came by today, and I showed him all the defects. Two windows will be replaced by the manufacturer due to damage to the film covering. However, for the window with the foam sealant, he said it will not be replaced, and I won’t receive a full refund. He said we would have to come to an agreement.
Oh, and in the meantime, he tried to convince me that a wider trim could be applied instead. But that would align flush with the water drainage cover, and even that wouldn’t fully solve the problem.
What do you think? Is it reasonable to insist on a replacement?
I would really appreciate any information.
