Noise From Upstairs Neighbours (Sound Insulation Company)

Dear Readers

The upstairs condo has a balcony on which the owners have guests and the noise is come down into the condo.

I want to know if there is a company in Bangkok which can help to fit a falst ceiling and inject foam insulation for sound into it. Apparently these companies exist in other countries.

I realise that there are other ways of dealing with the issue, but I have made up my mind to do this as it works.

I would really appreciate it if anyone could point me in the right direction

Cheers
