What would it cost to soundproof an apartment?

Hi there,

Well I guess you would just want to do the ceiling and if it is already finished then we would have to recover the whole ceiling either with double five eights and green glue between it or some soundboard.

The price would very you're probably looking at about $2500. But you would have to post some pictures because if it's being lived in at the moment the cleanup from all the dust would be major and everything in there would have to disappear in order for the work to be done so I would have to see it.

And it would take five consecutive trips so the week.

I'm assuming you are referring to sound coming through the floor/ceiling.

Sound travels through vibration so the drywall for the ceiling in the basement would have to be removed and replaced. After removal I would suggest installing Roxul soundproofing insulation right up to the walls as the sound will travel down the walls. This will create a dead space where sound will be trapped and stopped. Afterwards, install resilient channel, which is screwed in on one side only. The other side is free-hanging. The drywall is attached to the channel which produces a kind of floating ceiling, again lessening the travel.

Because this is an apartment you should install type X drywall which provides a longer burn time in case of fire. You can go with more expensive sound board, up to 80$ a sheet(the equivalent of 8 sheets of drywall).

After is re-taping, plastering, sanding, priming and painting. All in all, the cost depends on the materials required and the square footage of the entire ceiling, plus disposal. So the entire job is not going to be cheap. If you want to do it right the first time count on upwards to $5000, depending on decisions to be made on your part and square footage.

Hi Kelly Richard is correct if you dry you may want to contact a foam insulation company to see what they can offer if you have no success let me know

All good answers, but you must also address the topside of the ceiling with a sound reduction mat between the finished floor and the concrete. I went through this already at a 2 storey concrete condo in Wasaga Beach. Can you get you neighbors permission to re-do that suite's floor as well? Just doing the hanging roxul doesn't address the originating sound, only half. (or less)

Extremely pricey in the end.
