“How to Soundproof old plaster Rowhome?”

“Dear PoPville,

I’m in an old rowhome, and while the sound between neighbors with our brick walls is fine, we have bedrooms on top of each other where you can hear EVERYTHING.

I’m determined to find a solution and I’m curious if anyone has added insulation between their ceilings and floors and if they had success?

Because most old ceiling/walls are plaster in DC, I’ve been told by contractors that adding insulation can be dangerous as plaster will attract too much moisture.

Other soundproof methods seem to be for non-plaster homes. So before I do anything crazy, I’d love to hear your thoughts!

As an FYI, I’ve tried to reduce airborne and impact noise by sealing windows and doors, double paned glass, and a healthy amount of rugs, but the stubborn issue is airborne noise between floors.”
