cost to sound proofing a townhouse common wall
The wall size is 17ft by 8 ft. I want to rip the existing drywall and double the depth of the stud (it's probably only 1.5inch thick now with crappy insulation) and use thicker/best grade insulation. Would also consider to build in two wall sconces as decor or some other artistic elements on the wall. what's the best sound proofing materials to use? And any contractor would be good at knowing the sound proofing material as well as the decor/art part? I'm in GTA. Thanks
