ᐅ Prefabricated garage – cable pinched during location marking

The prefabricated garage (Zapf) was installed. Since it was misaligned, the garage was re-leveled a few weeks later. In the meantime, I prepared coaxial cables for the satellite system and placed them on the garage roof. Unfortunately, part of the cable ended up between the house wall and the garage wall. During the re-leveling, the installers squeezed the cable between the garage and house walls so tightly that it cannot be pulled out without damaging it.

The garage company denies any responsibility and states, "In principle, we are not responsible for cables, coverings, or their installation between our garages and other building components. This is clearly described in our delivery description, where the property owner or builder is held responsible."

To me, this qualifies as property damage and could involve product liability. Am I mistaken? Does anyone have advice on how I should proceed?

I would generally say that the clause is not valid. But I'm just an amateur. They can't just do whatever they want if there's a cable lying there.

If it's coaxial cable, you can go to a hardware store and get a few meters of cable and two connectors and fix it yourself quickly. The whole thing won't cost more than 10€. However, I don't know the exact circumstances based on your description.

I wouldn’t make a big deal out of it; no one, including yourself, thought about the cable, and I wouldn’t blame the garage workers. The damage is minor and easy to fix.

There are 4 coaxial cables, and connecting them without signal loss takes a bit of time. I also mentioned beforehand that cables are already installed there.

Of course, I am not familiar with the preparation of the installation, nor the amount of cables or whether they could have been moved aside. I am also unaware of any other circumstances.
To me, it gives the impression similar to "Watch my car" instead of quickly moving it aside when it’s foreseeable that space will be tight, and then blaming others because something happened.
I could be mistaken. Even four squeezed cables are not a major issue, though annoying. I would measure the attenuation and leave everything as it is if the measurements are acceptable.

These are coaxial cables. I understand what you mean by signal loss, but you can even insert the cables a few centimeters without shielding into the TV and it will still work. Even as a beginner, one side of the connector can be attached in less than 10 minutes. After doing three, it only takes about 5 minutes. So, in about 1 1/2 hours, the whole thing is done. I wouldn’t make a big deal out of it, although I understand it’s frustrating when the company shows no goodwill.
