Thank you so much for this video. I brought a older home last year that was made with stucco walls. It is freezing in the winter. Not a drop of insulation 😳😳😳 I'm going to try this. I will definitely report back how my electric bill is 😃 afterwards!!!!
For tight packing you drill in the middle and start with the hose all the way up. When it's full, retract the hose and knife it down all the way to the bottom. Turn on the blower again and slowly pull the hose. This is to fill the gaps and maximize the density.
I know this video is old but thanks for posting. Tight pack and diamond blade are great tips. Getting ready to do this over the weekend. Do you remember how many bags you used per cavity?
Yeah... or does the insulation settle all the way down to the bottom of first floor? Some house had balloon framing so there is a cavity running up from first to 2nd floor so that's why I'm wondering.
I believe the insulation come out at the top and falls to the bottom. Slowly filling up the cavity. That's why I can't understand why he doesn't just drill the holes close to the top? Pushing the hose up and then pulling it back out seems to make less sense than just starting with a hole at the top of each section. But maybe I am missing something?
Not a dumb question. Marking the blade is a great technique. If the wiring is attached to studs and you measure correctly you should be able to avoid the wiring.
How Thick are your wall cavities, 4 or 6", and did you have trouble maneuvering the hose around the plaster pushed through the lath inside the wall? Getting ready to do this project but with blow in fiberglass, also planing to drill holes from the outside wall (wood clapboard). Just wonder if I'm going to run into issues with a tight 4" wall cavity further restricted by protruding piaster and using a machine meant for blowing attics
Just curious- why decide to do it from the inside? Seems a lot more work moving out things that are inside the house, cleaning up the drywall dust and cellulose particles, etc
I've done it from outside also. I do prefer that if you are planning on siding the house anyway. Also if you have vinyl siding you can remove one row of siding and do it from the outside. This house had aluminum siding and the apartment was vacant because tenants switched out.
Does the hole have to be that big? Can't I make a smaller hole? Why not make the hole on the top of wall since the hose is directed to the top anyway? Thanks for making the vid, have lathe and plaster and looking for ideas (minimally invasive ones).
@@Iiifly2 I don't have any answers, just questions like you. I think the size of hole depends on the type of system you are using. The type of blower and insulation will dictate the diameter of the hose and hence size of hole. I think you can make hold on top but then you just have to have a stool always to step up to that height. I wish there was a system that was foam and used a small diameter hose, maybe like one inch diameter or something. It would take longer for the foam to come out since the bandwidth is less but that's ok, that's the tradeoff. If you find such system please let me know.
@@nofurtherwest3474 SE thoughts here, would rather make smaller holes towards the tops of the walls, harder to see, easier to patch, I am going to research and see what I can find out about equipment
I know its early still, but did you find the adventure worth it in the saving department ..... i was wondering because i got to do mine but the wall will be all strip, maybe rockwool would be better in that case?
your video is the only one where I’ve seen you push the blower towards the ceiling rather than the floor first. your method definitely looks like it worked extremely easy but do you have any thoughts about filling it from the bottom to the top? or is it basically the same thing and it’s just preference? thanks for the video and hopefully for your response!
This is a great video that shows 3 different techniques using plexy glass so you can see what works best. They demonstrate inserting the hose to the ceiling.
If doing this from the outside after removing vinyl siding, is it difficult to find the studs/cavities to fill them? My nightmare is I pull the siding off and can't figure out where the cavities are to drill holes and fill them from outside. Doing this from inside would be extremely difficult as we live in my house.
Is it possible to do this while the resident and all his (my) furniture is still there? I have an apartment in a co-op, and I want to do this for the purposes of sound isolation. My living room wall is fine, but I hear every word said on the other side of the bedroom wall. Possible to just wrap furniture in plastic, plastic off the doorway, and do this job?
Yep , cover it , finish the job, patch holes repaint and clean, uncover, reclean dust, uses floor drop sheets , hang a drop sheet curtain over bed room door, and keep closed to isolate dust from spreading to other areas , block the floor vents, remove window screens, then you can help push dust outside with a box fan, use a shop vac with dust bags,, I'm a retired pro, your welcome
@@kickfliphctp I taped over the holes with mesh tape. Then applied the mud thick. It soaks through the tape nicely. After it dries for a few days you can sand and apply 2 more coats.
You might need a stud finder. If you look very carefully you can sometimes tell where the screws or nails are in the wall. That should let you know where the studs are. Also you may be able to tell by knocking on the wall.
786otto , thanks. I think I understand. It will be much easier to push the rigid hose up the wall & the cellulose is more tightly packed coming out of a smaller diameter tip
@@ynnamduff5721 Exactly ,as you blowing it in go up and down and pack it it , i bought pvc semiflex hose 2" size about 10 feet long and worked fine .More and tighter you blow celulose in the wall better result , it is a dusty operation so best if place is unocupied .Good luck.
A vapor barrier is always great. You should have a vapor barrier behind the siding. You can't add a vapor barrier without removing the sheetrock or lathe and plaster.
I'd say no. Plaster walls were laborious and time consuming to build, and of higher quality than drywall. If you live in a historic house with surviving original details that has the original plaster walls, it's definitely worth it to keep the original walls, as they add to the character of the house.
you guys probably wanted better masks. I don't know how people end up with permanent damage from 9/11/01, but if it's possible to ruin your lungs in a single day I feel like that's enough to warrant a quality mask when doing old house wall stuff
Interesting 🤔 So Doctor energy Saver wanted to charge $6118.22 to do the wall and Attic are they Fucking Crazy Now I see this Video it’s so easy to do thank to this video A project needs to be made

Any update?
Empty promise
Update
Thank you for taking the time to make this video.
You make the holes up high toward ceiling and put the pipe down it and pull it out as you go
The best DIY video for indoor insulation wall. thank you for saying how to get the machine!
why not just drill at the top?
That is what you are supposed to do
Valid question 😂
Because that would make sense

One bag filled about 1.5 cavities.
@@pjbuttertime why can't you cut a hole in the top and fill it from the top?
can this cause mold ?
No, cellulose insulation is quite good.
Dense pack is the best they say because that stuff settles and leaves air pockets.
So you did the upper half, do you also remove the hose and do the same to the bottom portion of the wall?
Yeah... or does the insulation settle all the way down to the bottom of first floor? Some house had balloon framing so there is a cavity running up from first to 2nd floor so that's why I'm wondering.
@@nofurtherwest3474 it settles dude

Why don't u make a hole in the top and fill it that way?
I was wondering the same. Why not start with the hole at the top. Seems like that would make more sense. What am I missing? Thanks for the video BTW.
maybe a dumb question but how do you ensure that you won't be cutting through any wiring?
mark the blade the thickness of the drywall (1/2" or 5/8") and then stop when u reach the mark and be careful
Not a dumb question. Marking the blade is a great technique. If the wiring is attached to studs and you measure correctly you should be able to avoid the wiring.
I need this done in Charlotte, can you recommend?
oohh is the house nice and warm now?
Yes. The heat bill is very low also.

4"
They are 4". It is easier with a smaller hose. And make the hole a little extra big
How many inches is the opening on hose ?
How do you know it’s tight packed?
Great informational video, thank you.
Excellent video thanks for sharing
About how much of a bag do you think it used to fill a column of the wall?
Maybe half a bag
Just curious- why decide to do it from the inside? Seems a lot more work moving out things that are inside the house, cleaning up the drywall dust and cellulose particles, etc

@@nofurtherwest3474 not yet. Heating season over so have 6 months or so to figure this out. Lmk!

@@greglemon230 cool sounds good!
Why on earth would you put the machine inside, it has a 50’ and 100’ hose, it was probably harder cleaning the dust than the project
Can you put the holes towards the top of the wall? Then blow it down the wall?
That seems like a great idea
I know its early still, but did you find the adventure worth it in the saving department ..... i was wondering because i got to do mine but the wall will be all strip, maybe rockwool would be better in that case?
This was a rental. I dont pay the bill. I'm sure it has to be much better though.

Maybe making the hole at the top of the wall and filling cavity would work better
What size is the hose or what size hole did you drill?
What about fire blocks?
Old homes with lath do not fire block in fact its open to the attic not even a top plate for some ..
If doing this from the outside after removing vinyl siding, is it difficult to find the studs/cavities to fill them? My nightmare is I pull the siding off and can't figure out where the cavities are to drill holes and fill them from outside. Doing this from inside would be extremely difficult as we live in my house.
Did you do it? If you get lucky with the 1st hole, you can just peak inside to see where the next stud is. Not a big deal
Get a high quality stud finder
What they don't tell you in this video is that the rental machines don't have a strong enough blower motor to dense pack the walls properly.
Nice video! Gonna do this in our sunroom
Same...my sun roof is burrrr central
Is it possible to do this while the resident and all his (my) furniture is still there? I have an apartment in a co-op, and I want to do this for the purposes of sound isolation.

How did you patch the holes afterward?
I used fabric mesh tape for mudding sheetrock. I had to sand and reapply mud several times to get it right.
@@kickfliphctp I taped over the holes with mesh tape. Then applied the mud thick. It soaks through the tape nicely. After it dries for a few days you can sand and apply 2 more coats.
I'm not am expert by any means but could you use same hole saw for drywall and use the drywall piece to place in plaster hole them mud?
@@ODRASyep.. screw in a shim on the back, place the cut out circle in the hole.. screw to the shim and cover with mud... easy
Good job!
I think it would’ve been easier iIf you guys made a hole Higher in the wall more closer to the ceiling
I agree to that.I will be doing this tomorrow and that's what I'm gonna do!
How big was the hole? So you only made on hole about middle of the wall? I want to do our garage
The hole was 2.5". Sometimes the rental equipment has varying sizes of hose. You may need to adjust the hole accordingly.
@@pjbuttertime can i do the hole more closer to the roof?
How much insulation did you use? What was the sq ft per bag and how many sections did one bag do?
One bag filled about 1.5 cavities.
40kg/m3! For walls.
Thank you 🙏
How did you find your studs behind the plaster?some of my are spaced 12 16 and 24 built In the 20s.
You might need a stud finder. If you look very carefully you can sometimes tell where the screws or nails are in the wall. That should let you know where the studs are. Also you may be able to tell by knocking on the wall.
How is it holding up ? Any mold I need to do this as well .. how did you find the studs that is my concern ..
Any advice would be much appreciated
Where did you get the diamond hole saw?
You can buy them at home depot/lowes/manards, or just order one off of Amazon
Should have ridgid hose flex pipe to insert in wall and pack celulose in cavity
Why?
@@ynnamduff5721 With ridgit hose you can push it into the wall and dense pack insulation lot better than just blowing it in .
786otto , thanks. I think I understand. It will be much easier to push the rigid hose up the wall & the cellulose is more tightly packed coming out of a smaller diameter tip

so what happens over time with NO VAPOUR BARRIER?
Good question I imagine it soaks up that moisture causing damage down the road.
Do you notice a difference since adding the insulation?
This was for a rental. I don't pay the utility bill however I was told the bill has been lower even during the coldest months.
@@pjbuttertime What an awesome tenant!
What'd you do about having a vapor barrier?
A vapor barrier is always great. You should have a vapor barrier behind the siding. You can't add a vapor barrier without removing the sheetrock or lathe and plaster.
Could you drill holes from the top and fill the insulation from top of the wall?
You can definitely do that. You my find it's easier and faster to drill in the middle of the wall.
@@pjbuttertime ok. Thanks.
is it better to just take it down and drywall?
That is better.
I'd say no. Plaster walls were laborious and time consuming to build, and of higher quality than drywall. If you live in a historic house with surviving original details that has the original plaster walls, it's definitely worth it to keep the original walls, as they add to the character of the house.
@@Ratplague707lol character? Hahaha no one will ever see them
That will be a diamond core bit,not a diamond blade.

Why not make holes at the top and let gravity do the work

I don't get it why do you guys destroy the walls at eye level instead of just going into the attic and spraying downwards?
The Problem is the air. If you blow cellulose inside there is no venting for the air. So your wall gets a bump.
What size hole? what is the diameter of the hose?
