I'm currently in the middle of a basement renovation project. I'm in the unfortunate position of fighting with my contractor because they did not soundproof an area properly as had been scoped out, and more specifically they did not apply Green Glue properly. I'm looking for some input so that I can approach them with as much knowledge as possible. First I'll start with the actual issue, and then I'll follow up with some additional details to provide some of the backstory in case it's relevant.
I paid extra for a soundproofing option, which was to include 2 layers of drywall with Green Glue in between for the TV/stereo area of the basement. This includes 2 walls and part of the ceiling. Issue #1
is that they didn't properly stagger the multiple drywall sheets, so the seams for both sheets are in the same spot. Issue #2
is that they only used one tube of Green Glue per drywall sheet. Issue #3
is that they applied the Green Glue with an incorrect pattern (single bead around the perimeter, and maybe 6-8 vertical lines in the middle). All one has to do is go to the Green Glue website and watch the how-to on the main page to see how this should be applied. Actually, all 3 of my issues are even addressed in that video.
My main question is...should I choose to fight this and simply have them redo everything, can the sheets be removed, additional Green Glue applied in the proper manner, and then remounted? Will removing the sheets compromise the existing Green Glue or the drywall itself...meaning, would both drywall layers have to be completely replaced?
Quick backstory in case it's relevant - the company we used I specified upfront I wanted to do some basic soundproofing for the area where I'll have my "home theater". They suggested ROXUL between joists in the ceiling, and multiple layers of drywall with Green Glue in between. Mind you I had not even heard of Green Glue at this point, but after they suggested it, I did a lot of research and decided that was good for what I was trying to achieve. Given that they provided this solution to me, I had an assumption that they knew how to apply it properly. That does not appear to be the case given that they did not use a proper amount, they did not apply properly, and they did not even stagger the drywall properly.
I tried contacting the Green Glue company, Saint-Gobain. Being on a Saturday, I didn't get a response, which I would expect. So I'm looking to get input so I can have a discussion with my contractor first thing Monday morning. I'll contact Saint-Gobain again on Monday, but it likely won't be until after I talk with the contractor. So I'm just trying to get as much input as possible before then, in which case I may not even need to contact the company.
Thanks in advance, and I appreciate any input you can provide.
