For this friend

Try to find out which of your friends recently made repairs, especially in the kitchen or in the bathroom and ask for this friend to visit. See how the tile is laid and, if you like the result, ask the master’s phone: the most effective way to find out something is still “word of mouth”. If there are no acquaintances with a new repair, it’s already worse, but you don’t have to be upset. In almost every city there are city forums on the Internet — try to ask for advice there, find out who recently made repairs and is satisfied, and who is the opposite: the names of unscrupulous masters or the names of the chatts will be excellent in choice.
