A company that does not follow its own business, does not do the job fondly and willingly. As a customer, you need to follow, squeeze, constantly tell. I was not satisfied with the overall functioning and the staff they worked with. Even if their work is incomplete or erroneous, there is no apology or acceptance of mistakes. For example, even though they connected the hot water connection of the boiler in reverse, I could only bring it to 3 far-fetched days to fix it. And when they came, I got the answer ”extra wages come out, we can't deal like that, labor increases". Come on, then I said I'll do it. They left without making corrections. You can see the final version of the work they left in the images I added below. After they left, I did the so-called difficult job myself. You can see that I also added the work I did to the last image. In short, you encounter simple requests that we expect in a business sense, lazy reluctant attitudes towards our demands. I definitely do not recommend staying away.
