How To Install Moisture Barrier in Crawl Space 

This is so much better than a full encapsulation and thousands of dollars cheaper. I had to do this style for my crawl space to pass inspection for a quick sale.

Installing moisture barrier under mobile homes is a little bit more complicated because you have very little crawl space and more cuts. would love to see some videos on the best way to install moisture barriers under mobile homes.

Very helpful demo, it's given me the confidence to do my own house. Had quotes to that job that made my eyes water lol.

Thanks for the video.

Thanks Chuck!

Awesome video..I just did my little house..

you are the best! thank you for sharing your knowledge. much love and appreciation

Videos like this are why I love RU-vid

Very helpful. Thank you!

I am glad you explained encapsulated spaces being different. Code says the barrier is thicker attached to walls and columns by six inches, overlays 6 inches per over lap of the plastic and is sealed at all joints. The interior walls would need to be insulated with hard installation I believe.

That's a easy crawl

the secret is a lack of closterphobia and no fear of rat poo

If that's a tight crawl, you should see mine. About to move to an old house with an 18" crawl. Im putting in a moisture barrier, dehumidifier, and sump. That's going to be a fun couple of days 😅

I'm literally stuck looking all over, hopefully someone can help me. My crawlspace the barrier is attached to the joists. Can I just use flashing tape at the seams and Rehang?

Thank you for sharing your knowledge! This is super helpful, I appreciate your generosity so much!

My opinion 20 mil for capsukation is too rigid, 20 mil is two 10 mil pieces together with reinforcded type mesh netting, plus someof those vapor barriers off gas ans it smells like cat pee lol

Exactly what I needed to know. Thanks

Hey Chuck, thank you for all of your videos. I do now believe that I can do my crawl space encapsulation myself. Thanks to you. I live in Montana and I have a 2,000 square foot crawl space with about 4'5" of head room. I have standing water in some places (not much). I'm going to put in drain tiles and a sump pump. My home does not have a forced air furnace. We have propane burning heaters (vented to outside) and a wood stove. I was going to get a dehumidifier and completely encapsulate the crawlspace (cutting off all access to outside). Then maybe put in a floor vent to exchange air to the single story home. Is this a bad idea considering I don't have a way to force air in and out of the crawlspace? What would you do?

Can I staple the vapor barrier up on the beam, floor joist in the crawl space instead of laying it on the ground?

Yes. I just decided to do this. And inwouldve have to take the whole roll in with me.

that’s a lot bigger than my crawl space, you guys made it look more harder than it should, what my father and I did was wrap up the Columns and roll out some 8 foot wraps.

I was worried but now I should not have any problem doing it myself.

that crawlspace has WAY more space than mine...you can actually CRAWL in that one

Great video & content...Thank you!

I only have 1220 sq ft and need to know what type of pins those are. I want to do my moisture barrier myself. And I also have 6 mil.

After seeing my 6 mil vapor barrier dwindle to nothing, I would recommend at least a 12 mil or more.

great video!

Just did mine today but didn’t use the wires to hold it down. Will this be a problem in the long run. The old vapor barrier got water on top cause it would flood really easy and it was 30 years old. Put a new sump in last week but do I need the wire tie downs?

will this help older cold home. my sunroom and living room gets cold. winter. i have it partially the front not cover would this really. help.sunroom need newer window.

So there is is a moisture barrier and then encapsulation. What criteria for one or the other? I was hoping to reduce condensation on my windows.

Informative video .. Thank you

So my crawlspace has been flooding horribly for years apparently. We have just excavated and diverted a river (literally) away from our home. Installed French drain and weeping tile. The builder or previous homeowner put down poly but there was literally 6-10 inches of water underneath the poly. So I have removed it all. The dirt is completely saturated down there still. Question, should I allow it to dry out a little before applying a new layer of thicker poly? Hope this makes sense.

Very helpful. Thank you.

I dream of flat crawl spaces....

Hi chuck, is it necessary to put foam insulation board on the walls or can I just use the plastic up the walls right over the concrete? I am removing the overhead insulation from in between the joists so there will be no insulation in the crawlspace at all. I am in Florida to add some context. Thanks

Dam, that guy is serious! He vapor barriered himself ! 😂😂😂

Thanks for the video - what's the name of the song at the end of your video??

How often?

what mil plastic did you use?

Watching on 2022

Do you need to put lime down before putting the heavy plastic down

Does forget your keys !

how do you hold vapor barrier down if ground is hard ,like with clay

Thx for the video. What pins do you use?

Ball park estimate what does a job cost?

Very helpful video..

Thanks that was helpful

Do you always want to remove old barrier or can you just overlap them?

👍👍

He said 6mm plastic ? That’s 0.2 or 15/64 of an inch. No way is his plastic that thick.

How long will the plastic last generally?
