Post: Mass Loaded Vinyl between floors for Soundproofing

Hey all,
I'm rehabbing a house house hack where I am living in the downstairs unit and renting the unit above. My unit is done but upstairs, before I put flooring, I've been looking into the best way to soundproof between floors and I discovered MLV as an option. Has anyone used this and had success?
Thanks!

Recently closed on a single family home with a legal accessory apartment in the basement. My wife, daughter, and I are living upstairs and renting out the basement. The house was built in 1938, and it appears that no measures have previously been taken to soundproof anything. We are feeling most anxious about us hearing our renters, and our renters hearing us with our often yelling toddler.
I have heard good things about using mass loaded vinyl to help soundproof. Has anyone on here laid out mass loaded vinyl under their main flooring and been happy with the results? Or were the results underwhelming?
This is the material that I am referring to: https://www.homedepot.com/p/Te...
Hi Benjamin, did you end up using MLV and how did it work?

Hi Joseph, did you happen to use MLV and how did it work if so?

I have a 3 bd 2ba condo and I'm looking to soundproof the shared walls in between the rooms. A total of 3 walls.
what is the best way to do this? I want it done right as this will be a long-term rental if everything goes as planned.
Based on my research here is what I am thinking I should do.
Remove the current drywall | Add Safe n Sound Insulation | add 1lb MLV |Sealant around the walls and outlets | Fire wrap around the outlets then add 5/8 drywall.
Do you think I need to add MLV on both sides of the walls or just one?
Any tips or recommendations?
Hi, did the MLV work well for you?

Hi all,
I was hoping to get some LVP recommendations for a unit that I will be turning into a STR. Preferably one that has good sound dampening qualities!

I wouldn't recommend doing that.
If the subfloor is too soft then the click lock joints on the lvp may not properly engage when you install it. You also increase the odds of the joints popping out of place once people start walking around on the floor and putting heavy pieces of furniture on it. This is more of an issue if you're installing it over carpet (don't even think about doing that haha), but the same general principles apply.
is the noise really that bad? There are other ways to deaden sound between floors, like adding an extra layer of drywall to the 1st floor ceiling and insulating between floor joists. These can be quite a bit of work, though, so I'm not sure if the ROI is there.
Appreciate the feedback. I live in the downstairs unit so i just want to take the extra steps and do everything I can lol. I already had blow-in insulation installed between the floors so i'm hoping that helps

Get an LVP with a pre-attached underlayment. This is standard for most new LVP products. Reduces installation time and costs and makes for a cleaner install. These products are intended to be installed directly over the subfloor.
Lifeproof from Home Depot is a good example of a quality LVP. There are plenty of other good brands out there, though... just do your research and read reviews. Steer clear of the super thin and cheap stuff. You should expect to pay somewhere between $2.50 - $4.00/SF for a good quality LVP (material only, as of July 2022).

Hey BP,
I'm rehabbing an upstairs unit of a duplex and wanted to put LVP. Does anyone have any recommendations of a good/proven underlayment to use to help dampen noise from the upstairs? I know carpet would be my best bet but I still want to stick with LVP. I've heard Floormuffler is ok.

Three things I consider when choosing a CRM for myself was...
How well does it integrate with other technologies I’m using. I feel that it’s important to have technology talk to each other to get the most efficient technology stack. Finding one system that does all is usually very expensive or sub-par.
How well does it integrate with my email. I like to have my conversations recorded and easily searchable through the CRM. I don’t like using the bcc email feature some CRMs force you to use.
Last, how good is their mobile app. It’s nice to have a “not so water down” CRM on the go. Using a desk top version of the CRM on a mobile device can also be inefficient.
I hope this helps.
Hi Elvin, based on everything you mentioned, which CRM did you decide to go with?
Thanks!

Hey everyone,
I was wondering if anybody had experience with "All the Rooms"? We have used AirDNA and Mashvisor before. I really didn't like Mashvisor. AirDNA was way better.
We operate a short term/medium term licensed property management company in the Bay Area and we are trying to get better data to pin point good neighborhoods for ourselves and for our clients.
Hi Gi'angelo,
I was wondering what software you ended up going with? Also in regards to Mashvisor, they also provide long term rental analysis correct? Where as AirDNA is strictly short term rental data?
