Do I recommend them? No.
You need to be a professional to understand what you need to do.
I wanted to fix the noise the hard floor was making, which, in my opinion, was squeaking and no other noise. When the "Technician" came and we spoke about it and agreed on things to be done, there was no mention of any different sounds – e.g "cracking."
Then- when the job was done, and I spoke to them, I found out that the squeaking was fixed as much as it can be, but there is a cracking sound as well, and nothing can be done about this…But was I not supposed to know about this before when the technician came in, and we spoke?
There was no mention that there are two different sounds, and yes… there is still much noise as you step on the hard floor.
I do regret not going with the one in Brooklyn… :(
