We're planning on moving to Waterfront soon and I want to find a renovation company that can properly hide my wires and AV system so that it's baby proof. I also want to know if they can sound proof the living room or the baby's room so that when we're watching TV, playing video games or listening to our hi-fi, it won't disturb her when she's sleeping.

From my last experience renovating our current home, the renovation companies are not very knowledgeable when it comes to hiding the wires and such. Any advice would be welcome.
