Jakub is a decent man. I just wanted to have a regular check about a possible leak I suspected, he got the details from me and explained on the phone, probably nothing I needed to worry about, just did not want to charge me for anything that was a low probability, but if I still wanted it done, he could come and do the check. He did a thorough one, and explained every detail, and put on his suggestions, and reasonings. I'm going to work with him in the future.
