My 100 year old house had a very squeaky second floor hallway. I was considering replacing the floors but fortunately found squeak knights online and decided to give them a shot at reducing the noise. The results were better than I expected. They did the hallway and part of the front room and there is a 90% improvement. I am so glad I took a chance on this service as it was much more affordable than replacing the floors and no mess. I am going to have them back again to do more squeak reducing magic.
