Is there anyone out there that got soundproofing put in their condo? If so, who do you recommend and what is the average price range?

Soundproofing in a condo is going to be an expensive proposition… You’d basically have to remove all the existing sheetrock (or plaster, which would be worse), and then do either 1 or both of 2 things:
1- insulate the space between studs, if it weren’t already insulated.
2- add something called resilient channel before the sheetrock- this is supposed to deaden around 40% of the sound…

You could then also add double 5/8″ sheetrock to increase the effect even further, but all of this would be very costly to do simply to soundproof…

the best way to do this is before consrtuction however I am assuming you are talking about a retrofit.

Are yot trying to do a home theater or does your whole condo need sound proofing?

If new construction a good way to do it is to use roxoul FASB (fire anntuantion sound batt) or mineral wool. both are a dense green insulation. this adds mass to the structure making it harder to vibrate.

from their you hang resilliant channel under the joists and then attach the drywall to that. this isolates the drywall from the joist. there are additional steps you can take by making sure the vapor barrier extends all the way down and using acoistical sealants at the bottom.
this isolates the vibrating floor joist from above from your ceiling.

My guess though is you bought a condo and can now hear the upstairs condo..

There seems to have been a time in the late 90s that builders got away without puting anything in between the units. I know 84 adams and 531 jefferson and many many others are like that.

As a retro fit… the principles are the same, you either need to add mass to the structure/wall or insulate the materials that are vibrating together.
You can add mass by blowing in insulation. In a retrofit one way to isolate is to use a product called green glue. this is very popular with the home theather crowd. You apply the glue to your current wall then install another peice of sheet rock over it. costs for the green glue are around .50-.60 a squre foot but now you need to install a new drywall wall over it.. cost for new drywall various a lot depending on the size of the job.
