Does anyone have any recommendations for contractors in Jacksonville for soundproofing a band practice room? This one is approx 11x13' with 8 foot ceilings. Not talking about sound absorption foam and insulation which mostly treats the acoustics within room but does little to block sound in and out(especially loud music). My understanding things including decoupling (resilient noise clips)and adding mass ( ie mass loaded vinyl behind drywall and or additional layer of drywall on top with something like green glue between) are needed to effectively do that especially for blocking low end.

Most of the companies I spoke to only do commercial work. After lot of searching I found two but i am still waiting on quotes back from who have not gotten back to me even after several follow-ups. Since this is an expensive project (and have been putting some money aside for the project for a while) i'd rather have work done by reputable contracting company with experience with such work rather then spend good money and find out results are lousy.

As a side note, I also have a family room that could use some soundproofing to cut down on traffic noise and while at it address upgrade poor insulation in that room.

Thanks in advance for any recommendations or helpful input on this.

You might try calling recording studios (maybe mega-churches too) in the area to see who they used.

My guess is that anyone who does this is going to be a "commercial" company since not many individuals have a need for it.

Do some reading first. The 'Studio Building' section of the forums at homerecording.com has some good links.
You essentially have to make a 'room within a room. Starting wtih an 11'x13'x8' room, you're going to end up with a room that is about 9' x 11' x 6'6". I don't know how big a band you have, but that's a small space that still would need acoustic treatment inside it (bass traps in the corners).

Try a product called Home A Sote it comes in 4'x8' sheets. I am a carpenter and first used it to block sound around elevator shafts so that an office could be put up against the elevator shaft. We used it in combination with a studed wall, insulation just regular insulation then the Home Sote instead of sheetrock it worked well. That was back in the 80's. If you do some research on line there is some polyurethane foam I had good results with, a machine shop up against grad student walls LOL. I drilled holes in the sheetrock at 4' and 8' high started at the 4' until it was full and then went to the 8' that can get a little expensive but you won't loose any floor space that way. I have built the room like MikeB said. I built a room inside a guys garage sheetrock on the outside R13 insulation in the walls and HomeSote for the interior walls. I checked back with the guy later He said they were rocking LOUD in there with no more complaints from the neighbors!
