Looking for company that helps with noise insulation of balcony sliding doors and entrance door

[Sambora]

Hello,

 

I am in process of renovating my apartment and I am looking for a company that I could use to improve noise insulation of my entrance door and the balcony sliding doors. I did search on google and came across a company in Hua Hin that is unfortunately fully booked for the next 6 months.

 

does anybody here know such company or a person that might be able to help?

 

Thanks & Regards,

Sambora

Do you want to improve one or more existing doors or do you want to replace the whole door.

I just ordered for my apartment renovation a new door with sound isolation.

I ordered it from my contractor. 

When I know more details from you then I can ask him if he is interested in doing that or if he knows a company which he can recommend.

My renovation and contractor is in Bangkok.

I would be willing to replace the entrance door but retrofit or improve the existing balcony sliding doors. The building management does not allow me to replace either doors without altering the outside-facing appearance which makes a complete replacement difficult to impossible. 
 

I will send you a few pictures through pm
