Questions About Soundproofing Ceiling For Footfall Problem


We recently purchased a 2 bedroom, 2 bathroom condo (~1300 sqft) that was built in 2003 and after moving in, we immediately noticed a noise issue (footfall) with our neighbor upstairs and has upset our quality of life – we hear them walk back and forth all day, vacuuming, arguing, etc. After talking with some of the other neighbors and one of the original owners, we learned that the complex was poorly constructed (at least from a noise perspective) and in fact, the builder / condo board went back into each of the units many years ago to blow loose insulation into the ceiling area of each of the units to deaden the footfall, but as you might have guessed, it didn’t help.

After reading about this subject and contacting some soundproofing companies both locally and through Google, the solution appears to be even less clear. I have learned that one option is to remove all of the existing ceiling drywall in my unit, then install 2 layers of drywall directly to the existing subfloor above with green glue, then install fiberglass insulation (or wool) between the existing joists, then decouple the new drywall ceiling by using RSIC (Resilient Sound Isolation Clip) along with hat channel; all of this seems 'terribly expensive'.

These are 2 story units, and we are on the main floor, and the neighbor is directly above us. The good news is that our ceilings for the most part are 10’ feet high and a local contractor has suggested installing 1x2 on the existing ceiling and then installing 3/4" foam board followed 1/4" drywall. There has even been talk of spraying acoustic foam (similar to that in recording studios?) between the joists without opening the ceiling by finding a company that can scope the ceiling and then cut open small sections as needed. We have chatted with the neighbor upstairs and unfortunately it seems they have some kind of hardwood floor without any type of acoustic underlayment which from my research would be the best option for noise, but unfortunately this is not an option as the HOA does not mandate any type of underlayment.

If anyone has any real world experience or suggestions on how to mitigate this footfall, we would surely appreciated it.

Thanks in advance!
