I have been using Fsb d.o.o.'s firestopping services for over a year now, and I must say they are excellent. The team is professional, knowledgeable, and always delivers high-quality work. They pay attention to every detail and ensure that the firestopping is done efficiently. I highly recommend Fsb d.o.o. for any firestopping needs.
