How to Soundproof a Room | Easy DIY Guide 

Alternative to SonoPan for Americans: This product is currently only available in Canada, but an excellent alternative (which I have a video about - link in description) is mass loaded vinyl which you can get here: amzn.to/34rxHFC.

We want to thank you for sharing your experiences and providing all of the amazing content. We just moved into our first new home and we are converting the entire upstairs into a recording studio and video production suite for our new RU-vid channel. We found your channel just a few days ago and man how my knowledge and understanding has changed. Your channel is an abundance of experience bottled up with clear and understandable explanations. We are grateful for the way you explain the choices that you make and why. I thought I was going to need to search many videos for different ideas but everything needed is right here. Thank you!🙏

I've been using Sonopan in Montreal for about 20 years. It's a great product. However, I did use double-layer 5/8" drywall with z-channel (with green glue) on some projects. Yes, I know it's overkill, but I did notice a difference. But Jeff is right, it's not worth the price difference for standard construction. Though code-wise, you need 2 layers of 5/8" between a neighbor's wall anyway. But if you're doing a recording studio (which I did), I went up to 3-layers sandwiched with green glue, and mass-loaded vinyl (I had a noisy neighbor, and street noise was quite problematic). It's also important that the drywall doesn't come in contact with the floor, ceiling, and adjacent walls. Give it a 1/8" to 1/4" gap, filled with acoustic caulking. Soundproofing putty is also important for electrical boxes. Important, get electrical box extenders for each box. Oh, and don't forget the door: depending on your needs, get at a minimum a solid-core door. If you have windows in that room and want to reduce noise to and from the outside, have your windows customized with double or triple-pane laminated glass. There's also another product out there that replaces regular drywall, it's called QuietRock. This is made in the USA (available in Canada too). It's expensive drywall, but if you can't get your hands on Sonopan, then this will replace it, provided you get the right thickness for the STC rating you want. Each sheet is basically prelaminated drywall with a green-glue-like compound embedded, but in 1/2", 5/8", and even 1" 3/8 thickness. The STC rating on those is crazy high compared to regular drywall. For the over-killers in you, if building an ultra-quiet room, such as a recording studio, you can also build a room within a room. I used this principle when I build 2 studios in the past. Now that is only useful if you're doing critical sound recordings. Having said all that, this sort of construction is to avoid sound contamination to and from the room. But if you're creating a studio, don't forget to do sound treatment by adding acoustic paneling to the walls. Otherwise, your room will sound echoey with all sorts of standing waves and reflections. In which case, you don't want your room to be perfectly square. But that is a whole other subject.

Not being the troll here but I thought he was opening the box to reveal an actual speaker playing music, not a cell phone that has zero low-frequency information. He could have wrapped that in a towel and got pretty much the same result.

OMG! DAD showed me this 45 years ago! He used it to illustrate how to break thermal bridging. I assumed no one used it. So glad to see it!

Not trying to question the authenticity, but I'm confused why Jeff's older videos on soundproofing (which use the alternate methods) come across in the same way of "this is the best way to soundproof" when he said here that he's been using SONOpan for years. I'm planning on building a home studio in the next few years, so I just want to make sure I'm taking the optimal approach. Would be nice to have an STC rating or comparison to the other methods. It all still seems a bit speculative. The phone in the box was nice, but a phone's max volume honestly isn't very loud and is mostly pushing higher frequencies (no bass), so it isn't the best indicator of effectiveness.

The lower frequency sounds are a bigger challenge than muffling a phone speaker.

I just gotta say this man has taught me so much about how to fix my place he’s practically my father at this point. Goes over each step, even the ones that might seem like “common sense”, and cuts all the filler so it’s just only juicy father-like wisdom. Thank you very much!

I was impressed with how that demo box at the start was so effective until you opened everything up to reveal a … phone. Not exactly an impressive proof of concept, especially for bass. Still. Good content.

this is going to be so good for my slau... drums studio*

I used the Sonopan panels when building my Shed Studio. I believe it works well but OMG what a mess when cutting it! I had green dust everywhere. I suggest wearing a mask when handling it.

lower frequencies, no probs. What about bass?

first three layers, 'oh wow, it really is eating the noise.' pulls out a phone. yeahh. not sure how that might compare to even a 30 watt amp.

Cool stuff. The phone in your box in the beginning only produces high and mid frequencies. How does it block low frequencies? Seems like you need mass for bass blocking, and that stuff doesn't look very heavy?

Major mistake was not securing the R-19 fiberglass batting to the top plate and studs with staples .. Stacking the fiberglass batting and using the friction contact with the studs to hold it in place will NOT be maintained over time. Eventually the fiberglass will slowly sag and compress under it’s own weight, resulting in a 2 foot hollow void at the top of the wall. Some battings have plastic latticing that can be stapled to hold the batting in place.

This is eye opening. My wife and I are doing sound proofing between rooms and have already bought all materials. This would have been a great if we had it as an option in the US. But thank you. This will go to our list of possible tools if we ever need to do it again.

IS this something that can be done to existing walls, or would this be something you can only do for new walls? I am looking to soundproof my office and am a bit intimidated on opening up the walls to do this. Open to any suggestions and would love advice.

I’ve been trying to figure out how to reduce noise, first thought about the walls then and noticed it transmits through the ducting system. Great vid/wall solution!!! The ducting in my place is driven by a single furnace. Great vidz on basement Reno/refurb abs dropping the heat duct to the floor to improve comfort down there! The last bit of logic to solve in my mind for my Reno is if there’s a way to reduce sound transmission between basement and upstairs mainly, whilst having a single ducting heat/cool system inc heat drops… for the whole house 🤔

Great topic, but the speaker from that phone is not anything close to a proper representation of any home audio system,yet alone musical amplifiers. Try a proper speaker with decent frequency range and power. Otherwise the demo sadly is useless.

Great video, I’m looking at adding sound reduction in my basement theater. 13 x 15 x 8.5. Priced it out to about 1000$ for the Sonopan and drywall. Very affordable. Looking at Home Depot Canada. Extremely helpful. Thanks!

STC ratings are only measured between 125 and 4000, while low end sound which is the absolute hardest to isolate/block (i.e. bass guitar, drums etc) lives at 100 or below. With that in mind, try placing a subwoofer in your “magic box” and turning it up the next time that you run a test rather than your cellphone.

Can you please actually *film* a sound test: FIBERGLASS vs MINERAL WOOL?? Since many professional builders swear that mineral wool is a far superior sounding insulation because it is 3 times denser.

while it may serve the purpose that green glue does, it's missing the mass. At 20% thicker, 25% more expensive, and at half the mass than type x drywall, I don't see this being better than double layer type x even without green glue. It may be worth it to reduce labour costs, but a Home Renovision DIYer shouldn't be using this product.

I hate MSV, its so annoying to install. I need to get this in the US asap!

Sound issues are always with low frequency bass. Any idea how it performs with a subwoofer in the box?

Wish someone could come up with a solution that didn't require making your wall 10"+ 🤦‍♂️

I’ve used rockwool safe and sound between floors. 2 layers were used and it helped with quieting noise above tremendously

I love your passion and I can see how invested you are in what you're doing. I also love this video as it gives me ideas for soundproofing our offices for out future build. Thanks for the quality content as always!

I tend to disagree on safe and sound, that stuff is amazing. I just purchased a new townhome and considering pulling the wall and putting safe and sound and then the sonopan and drywall. Think it’s worth it or just use the sonopan?

Try that with a low frequency source, something like 100Hz

Solddd. Thank god I waited before I sound proofed my entire house!

Long time viewer, been watching since 2018 or so. My home project was unique, the background is simple: I remodeled a 1920s home and I wanted it to have a nice, cozy and insulated sound dampening so that if I'm watching a movie in the living room, I can walk downstairs and not hear it 'that much'. The purpose was simply for the notion of eventually living here with someone else, not specifically (and only) by myself. I went a little more than overboard however. Background at the end. So for my total cost for drywall, insulation and green glue, I was looking at about $10/sheet or about $900 or so for all the drywall needed for my entire house. This accounts for the areas which I doubled in drywall, with green glue. Green Glue I spent around $200 or so on, as I doubled the drywall in the main bedroom, the wall that sides both the two bedrooms, the region where the toilet is at (Everyone likes quiet lol). And in the living room / dining room shared wall. In addition, I spent about $500 or so in Insulation through the entire house, insulating every wall. I also spent another $60 or so on rigid form insulation for the upper top hats, to keep density up in this area, and another $200 for the ceiling insulation across each lower part of the house. Then another $50 or so on foam insulation spray for the outlets, romex and low voltage holes, etc. I think given the technology at hand, if it performs just as well as double drywall with green glue, and at the weight of this being 27lb compared to the 48lb of the 5/8ths drywall, I'd 100% sacrifice that extra couple inches of floor space and save and overall back from that entire overhaul probably just to break even in cash. I'm sure the scructure would thank you, too, since 2 layers of drywall gets heavy. Fortunately in my scenario, the house was already double drywalled when I got here (Well it was drywall overtop of lathe board lol...). Anyway, here's the background: My house is smaller, 1100sqft total, 2 floors at about 550sqft. It's a symmetrical rectangular house, where each side at the first floor is split into 10-11ft, and they're "long" sides. So the kitchen/dining room side is a long expansive ~20x10, and same with the living room side. Next is the staircase, which leads up to the upstairs small hallway. The hallway starts with a smaller bathroom, about 50sqft in total floor space when provided with a 2ft by 3ft shower (at the entrance) and a bathtub at the end of the wall (shower is separate from the bathtub). On the wall ajdacent the bathtub is the bathroom vanity, a small 24" with a toilet at the far end of that wall (With a window there, as this 1920s house had a window where the toilet was. I kept this construction all the same). Of course, I'm a little crazy and replaced all of the 1920s cheap windows with moderately lower cost Pella duel pane windows. Continuing through the hallway is the first bedroom. Originally this was the 'larger room', at a womping...10x10ft. The next room is on the 'right' side of that, sharing the same wall and was originally 10x7, and is now 10x14. My original design goal changed over the years. It eventually transformed from 2017 to 2019 into "I want a smart home" and "I want it to be comfortable for a family living". Originally, the plan was to rent. But as times got tough for me, I moved in and have been happy living here since. So for each room, I ran 14 gauge speaker cable through the walls. In most of the rooms, it's just to a singular in-ceiling speaker that has an in-wall Pyle Bluetooth controller to it (Which I soldered up to be hardwired instead of the power supply). The reason was to add Google Homes or Amazon Alexa's to the walls, eventually I'll add those in place, but for now it's used for my cell phone and background music. Additionally, in the living room I ran a normal 7.2 surround setup for that speaker cable, with an additional 4 overhead in-ceiling locations. The purpose was a 'true' 7.2.4 Atmos experience. In the bedrooms, I ran a traditional 5.2 setup, with 2 ceiling atmos speaker configurations. Let me tell you, I don't regret this for a moment. Instead of 'just sound proofing these two rooms, I decided to just go the distance with most of the house. Currently in 2022 I'm nearly finished with the project. The only thing I have left as far as 'construction' is concerned is baseboards and decoration, such as building furniture. I went with butcher block countertops, homedepot east haven cabinets i modified to allow recessed LED smart lighting, and ive already built a few additional cabinets utilzing a lower end table saw and a few tricks ive learned across youtube to do this. I work in IT, not even remotely close to 'construction' and it's my 'weekend hobby', when I'm not working on my car, playing drums or finding something else to get into, at least. But with my project nearly complete for 'construction', now it's just wood working, potentially some unique welding ideas for furniture, or some cool smart home ideas...I really need to get back to utilizing home assistant like i did in my apartment, as that's one thing I'd love to pair up with the number of smart devices i have around the house. I just need to 'get there'. Also, it looks like we actually have this at my local home depot. When I add some walls up in my basement, I may consider this 100% since it'll certainly, almost 100% guaranteed, save me a TON OF MONEY compared two two thick green boards drywall lol.

The more soundproofing videos, the more I'll watch. The Biggest thing making us considering remodeling or move atm

Wonder how this would work for drums 🤔

The frequencies from your phone are pretty easy to stop. If you used a jbl portable blutooth speaker at a moderate volyme that would simulate real soundproofing.

Love your videos! Can't wait to renovate my new unfinished basement!

This is fantastic and timely with my basement finishing plans for this year! I've seen these in Home Depot before, but this gives a good breakdown/comparison over other soundproofing options, thanks for the info.

Great tips sir. Thank you. Was about to ask you for tips on soundproofing the ceiling, as I have an up/down duplex but you answered it at the end. Thanks again and for helping out a fellow Ontarian

Question : Regarding a common wall in a semi-detached house. The priority is using the least amount of space possible, so applying a layer directly over the existing wall. Which one provides more effective sound reduction. Sonopan with a layer of drywall or Quietrock with Green Glue ? Also what's your opinion on Green Glue vs Lowes Indoor/Outdoor Adhesive ? Thanks km

As a hobby, I make sound-deadening “wall art” panels, using basic 1”x2” frames, a bit of canvas, and a tapestry or other decorative fabric. I fill the inside with 1” fiberglass insulation, and typically do 3-panel sets. I wish I could get a hold of this kind of material. The panels I make are great for large interior walls in common areas or offices/bedrooms. Measurable sound decrease, but I wonder what it would be like with Sonopan under the surface.

I’d like to see some info on soundproofing ceilings in a basement. Especially when they contain lights and or hvac. Thanks

Will a door that is not sound proofed, right next to the sound proofed wall, nullify all the sound proofing effects? Won't the sound just travel through the door and nullify the effects? The same way a very small hole in a blackening curtain can create enough bright light to ruin the effects?

Silence is golden. Ducktape is silver.

Please stop working with glass wool without adequate protection, and never use that toxic material for interior insulation, the VOCs go through drywall easy. Extremely toxic material.

GOD BLESS CANADIANS!!!!!! Americans have been silenced, we are no longer “allowed” to e revise our constitutional rights under liberal tyranny. 35 years ago when I got my drivers license, my grandmother told me if I ever had any trouble on the road, find a trucker. They would help me. THEY ARE HELPING THE WORLD! Thank you Canada ❤️❤️❤️❤️

9:00 jeff dont be so dramatic, you can fit roxul in those cavities, you just score the insulation lengthwise where the stud runs and fit the stud in the score line. That said, i am not sure if the roxul is worth the price premium over the pink. but i think it is marginally better

ok but .... my man .... there is one thing that everyone on youtube has been ignoring when explaining these things .... what if I want to hang something on the wall .... a painting or I need to fix some furniture to the wall .... what then?

I'm here reading comments trying to find out what song was playing!!! Anyone?

Ahh man, I wish this was uploaded a few months ago before I already started building my sound booth. Alternating studs to reduce sound transmission is such a great idea

Hm. Frankly: there is no such thing as a wonder-material that outperforms the „normal“ material as and appropriate design. I know, you are kind of hinting to it later in the video, but the video starts as a sketchy ad. But that’s probably only me.

How is SONOpan for sound absorption? Can you reverse the order of the drywall and the SONOpan so that the Sonopan is facing into the room to help reduce echo?

Everyone agree this CLIP made our day:

Hey Jeff, You're correct (I looked), I cannot get Sonopan in North Texas. I am designing and will soon be building a new studio and, after watching your video on mass loaded vinyl, will be incorporating that into my build. The walls (2X6 base & cap with staggered 2x4 studs 16" OC) and ceilings (12" engineered wooden I-Beam joists) of the studio will have 1/2" outer layer of OSB (studio being built inside shop area), Rockwool, 1/2" layer of OSB, 1-lb MLV, and then a 1/2" layer of "QuietRock" will be final interior wall / ceiling inside the studio. Being a metal drummer, I play loud and would like the ability to play whenever I want, without upsetting the neighbors. Yes, this is an expensive solution but, if I want to play at 2:00 AM, I don't want the police called on me for disturbing the peace. Thanks, Tom

I'd love to do this, but what do you do with a doorframe when retrofitting an existing wall? At least one side will now be thicker. Tear out the frame and rebuild?

This is a good idea . Soundproofing is EXPENSIVE ! I ve done it and it’s critical work to be done right .

Dude! This is game changer for me! I going to take this and insulate my basement/ ceiling and create an ISO box for my amplifiers and I see the alternative for us Americans. Thank you!!

Saw your other sound proofing videos and been waiting for one about sonopan, awesome. More importantly what was that song it sounded pretty rad lol

no Mass loaded vinyl? no green glue? Does it compare? If this board is better than that whole setup I would have used this..

Sound based on a Phone Speaker 🤔

it's even better if you use resilient bars between the gypsum panels and the sonopan

So, just the outside of the wall needs the SONOpanel, correct? 🤔🤔

I searched Sonopan on google and STEICO at the Hope Depot here in the U.S. showed up. It says acoustic underlay. Can it be used in the same manner ?

I need this in my whole apartment, I have terribly rude neighbors that bang and stomp at all hours of the day

Sound proofing against a little tinny phone speaker is not the same thing as sound proofing against large bass waves that come from, say, big sound system or a drum set. I could hide a phone playing music with just the insulation and the cover on the box.

Hi, will this isolate the sound of drums? Also about the low ends for this material? Thank you so much for helping. :)

Hold up- what is that song at 0:30 it sounds amazing and I need it - EDIT NVM IT IS: Fight to Win - Sven Karlsson

awesome! I'm looking to sound insulate my ceiling and was told to use resilient channel because a large part of the noise is from footstops/people dropping things upstairs. Would you suggest still using the resilient channel or would this do the trick?

If w have cement wall, & i built wooden frame, the wooden frame shouldn't touch the cement wall at all like to not install the frame on the cement wall with screws? can u explain it?

Only great if you live in Canada as Ive tried to get sonopan here in the US and distributor makes you buy a ton even if you dont need a ton. Not sure why home depot cant carry this easily since they already do in Canada

Would you skip the resilient channel with this setup?

This is amazing! We're buying SonoPan based on this. Quick question, the ceiling already currently has some 3 and 1/2 inch fiber glass insulation, pink panels. Could we use these and add more or should they be discarded? What's the pink fiber glass panels that you show on this video?? Thank you so much!!

No F'in way. Hi Jeff, thank you for giving me a shoutout today (11/14/23) on toilet recommendations. I am in the middle of some serious home reno.. you are my go to guy and now have my uncle following you and your recommendations (you 2 think alike). Anyways, in addition to the new toilet (bathroom remodeling) I am in the process of building a home theater in between 2 kids bedroom. DOES THIS REALLY WORK? I was about to decouple with a 1-2" space between 2 separate studded walls. I want to know more and want to discuss my project more.. how can we connect and how can you help me. My contractor says just to add acoustic panels on the wall and I will be fine... I wish you were / are my contractor.

I was literally just going through your soundproofing videos throughout the years.

So compressing fiberglass insulation doesn't have an effect on sound cancelation? 🤔

Would it be worth it to use resilient channel between the sonopan and gypse?

I almost laughed out loud when he pulled that phone out of the box. Then he had the gumption to say, "if you're building a studio" (I did just laugh out loud). That conducer of a cell phone is not comparative to a 5,7,8,10, or 12" Cone of powered and amplified studio monitors... From the sounds of it (I am watching in x2 speed) It's probably not even even putting out content with any 100Hz waves, not to mention it impossible for sub frequencies like 60,50,30Hz to becoming from a phone. Those and any information below 125Hz are the problematic frequencies in a music studio.

Accustic and thermal insulation have the same challenges. You can have the best insulation in the walls that money can buy but that doesn't matter if you leave your windows open. Sound travels through holes like the one under the door. 😜

I found an outfit that will import Sonopan to the USA (I forget who). But they only sell it in increments of units (60x sheets). I did the math, and even if I drive to / from Canada (Utah Lethbridge), I'd be saving $3,500 (cost of Sonopan + gas + trailer) on just the Sonopan to soundproof my basement. With a home theater and a work from home office, it might actually be quiet!

they, SonoPan, DO NOT sell that product in Europe... any alternatives? available only in Canada! WTF 😡... soundproofing is common need worldwide

Sonopan is just one brand name for Light Weight Density Soundboard (LWD Fiberboard). Sonopan does not compare its product’s STC ratings with other manufactures of Soundboard. In the USA, the only way to obtain any brand of soundboard from any consumer Warehouse Building Supply is only by placing a special order. Places like Home Depot and Lowes only stock and deal with inferior building products and material, usually made in China. All quality items ordered through these stores will cost you a premium markup price. That has been my experience and I’ve built this standard sound proof wall many times in renovations.

Jeff, Thanks so much for all your help. Im almost at the drywall stage for my basement finish. Im looking to keep the sound of my home theater sound in. You like this vs metal furring channels with RSIC clips and two sheets of 5/8? I have to drive 6 hours to pick this up

Would this also work floor ceiling, so that you don’t hear footsteps?

Who wants this now? Who wants to sound proof their gaming room, bedroom, home office? I'll tell you who: *Everyone.* China is selling a ton of adhesive and non adhesive foam panels on Amazon and ebay that don't work, because everyone now wants sound proofing. They work for studios only. The market is screaming for easy square foot adhesive panels THAT WORK, and they just don't seem to exist. If you know about this stuff, patent some new solution and you'll be another Lamborghini-owning youtuber.

Using the extremely low-frequency limited smartphone as a test source for evaluating sound isolation is laughable. Mid and high frequency energy - which is all a phone is capable of producing - are not the frequency ranges that matter to isolation. It's LOW frequency energy, say, 50 to 150 Hz (cycles per second) that's difficult to control and energy in this specific frequency range is essential to any meaningful acoustic isolation test.

Our son is at the age where he likes to watch porn on his tv, so we are soundproofing our bedroom wall so that we don't have to heard him.

Absorbing the sound from a tiny cellphone speaker is hardly an impressive achievement. Show me an attenuation graph from 100-1000Hz and I'm interested.

LOL just the fiberglass is good enough to stop the weak sound from an iphone.

I was recently mesmerized with a soundproofing video Jeff made 4 years ago. This time I found a more recent video that covers soundproofing with new techno that is more affordable. I have some questions about soundproofing a up/down duplex that has recently been completely renovated with new walls, ceilings and floor covering. Does Jeff reply to questions here?

What a lot of 'snake-oil' this really IS. It's a wee phone, phones are not like NOISY-NEIGHBOURS, GET REAL dude !!!

Can this be installed over a neighbor’s entire house?

Stop shilling this product, you have a great channel but this has already been debunked by professional studio makers. You would have a better STC rating if you did 2 layers or drywall in your test assembly and not 1 sonopan and 1 drywall. Your misleading people on this. No serious studio builder would use fiberboard at all. You need mass. You need mass to stop the sound and decoupling, sonopan does neither.

Do not be a hack and cut your studs in a stack by cutting one over top of other one with a circular saw repeatedly. You are gonna end up 1/2" short or long by the 8th stud. People who watch these videos are not tradesman. They are homeowners with limited experience and knowledge. They are not in production home building. Just be smart and setup a miter saw table cut your studs to the length with measuring tape. It will take maybe 10 extra minutes than the hack way. If you want to use your circular saw. Have one stud as your template and use it to mark your cuts. Jeff's way is for framers who build crappy North American houses.

I need to soundproof my extremely paper thin walls I can even tell my sons mini nest to stop!!!! However, I am a bit confused. If my wall is already a stud wall do I need to build another stud wall if using this system or just take the wall back to the original stud? Not sure if I can get SONOpan as I am in the UK but I will have a good go!! 😂

I just saw an ad regarding 3M Damping Foil. I never heard of it before. Any testing of it, especially in comparison and/or conjunction with this product?

A phone playing only high-mid and HF is such a lame test - put your money where your mouth is and show us broadband STC figures.. Sadly, the gullible will fall for it...

I don't think that Matt Risinger would agree with you there! Promoting products that don't sponsor you!!! What kind of a monster are you 🤣🤣🤣

Thank you very much for your videos I learning a lot I would like to where I can find those green panels I am I Quebec Canada and how can I soundproof a room with existing walls I am lady that fix everything in my house thanks to you I really appreciated what you do because you helping people thank you for that Sincerely Martha

Nice video but I will question that an STC of 70 is achieved with this method as claimed in the video. Have you performed any test to prove it as the Sonopad does not provide more soundproofing that a layer of drywall and 2 layer of drywall will provide an STC of around 63

Fiber board? Maaaan I just happened upon this video. I need so much help for my apartment in Philly. I share one kitchen wall with a noisy neighbor and unfortunately have a worse neighbor below. Things have gotten better but still they both show off randomly. I really want an easy way to soundproof my kitchen wall. I cannot build a temporary wall in an apartment especially not using all of that stuff. Please advise. Tx

I live in a townhome. My neighbours aren’t the quietest of people, with lots of thunderous running/jumping/stomping around the house, slamming of doors, and the weirdest of all, they have a drawer that is already kinda loud when they open it, but when it’s closed, they just let it go in at full speed so that thud is loud. Can I do this on my side of the wall and reduce noise transmitted from their end? I don’t even know if it’s worth opening up the drywall just to get this done because of how much work that might be involved.
