Need ballpark costs of soundproofing a small condo
I'm considering buying a small ground floor apartment-style single level condo of about 700-900 square feet and likely to be between 5 and 10 years old. I have not picked out anything yet, but they are all at least vaguely similar in size and layout.
If I buy, before I move in, I want to get it soundproofed as well as is practical, by replacing interior dry wall with QuietRock on all the walls that are either shared with neighbor or that have exterior (street or parking lot etc.) on the other side. I also want to add additional soundproof glass over the sliding glass patio door and medium sized (3x3?) window that would be in the bedroom or living room.
I would also like to remove the ceiling over the approx 12X12 master bedroom, treat the underside of the floor above with soundproofing and then replace the bedroom ceiling with a more soundproof version.
These are the things I'm looking at.
Quietrock walls facing outside and shared wall: http://www.quietrock.com/
I would use "Solution 3" over the bedroom ceiling: SOUNDPROOFING CEILING
I would add soundproof windows over the existing windos and sliding glass door to the patio:
This is just an example of a floorplan I might choose"
If I chose the floor plan pictured above, I would want QuietRock along the master bedroom wall all the way to the walk in closet, soundproof the master bedroom ceiling, add soundproof glass over the slider to the patio and the window behind where the sofa is shown.
Other condos I would consider buying would be somewhat similar to this. What price range should I expect the cost of having a contractor or handyman do this work?
