Do I need to insulate subfloor if I insulated my brick Foundation

Thanks for information, what if your attic has paneling already and you want the whisper pan

May I ask what is the mode setting for on the front interface ...just got mine June 2024....after washing filter and reinserting the unit sounds twice as loud... Thanks for time

So then its an easy DIY project?

How do I buy this product? Can I get your phone number?

Michael, code is different for covered vent / open vents for where? Are you talking about N. Carolina?

Here in Illinois! When I call companies near me, they say that soda blasting is too messy to do in a crawl space. Instead, they use a HEPA vacuum and then spray it with chemicals.

What’re your thoughts on laying down a second layer of vapor barrier over top of our existing vapor barrier in our encapsulated crawl space. It’s about ten years old and we’ve been down there a lot doing plumbing and other maintenance. The barrier we have now looks rough and has holes.

Hi! We had mold air testing done in our home and the mold in our home air matched the air in our crawlspace. Long story short, there is absolutely no visible mold. We also just had all of our duct work replaced because there was gaps between the ducts and our vents but there is still mold in the crawl space air. Is it possible that it is just coming from the ground? If so, how would I deal with that without having to use harsh chemicals to kill it?

We bought a home with a crawl space. We have zero knowledge on them. The crawl space is completely sealed. There are no vents anywhere on the outside walls. There are 2 vents in the crawl from our heating / air conditioning. Last winter my husband went to check on the sump pump in the crawl and said the crawl was hotter than the house because the heating/air vents were open fully. So he closed them 3/4 of the way. He went to check the crawl again today and said there is some condensation on the “gravel” (dont know what it is) he said not much but there is a line from the pipe condensation. Our question is, should these 2 heating/ cooling vents be open/closed, seasonal? Thank you.

I don't see the link where I can purchase the mold home test kit. Will you send it to me? Thanks!

For Frigidaire, if you call the number on the dehumidifier, in 10 minutes you reach the "extebded warranty" person, who then put me on hold for 35 minutes. The lady said that they don't think it is recalled, even though the CPSC website clearly says it was. Who do you contact?

What is a good brand for a crawlspace fan? I live in a salt air environment near the beach.

I AM INTERESTED IN THE E80 MODEL- LOOKING TO CONNECT DIRECT TO WASTE LINE - DO YOU KNOW THE SIZE OF THE DRAINAGE TUBE COMING FROM THE PUMP TO WASTE LINE SO I CAN PICK UP THE RIGHT SIZE CONNECTOR TO 3/4 INCH PIPE CONNECTED TO WASTE LINE- THANK YOU

Anybody have any tips on insulating a crawl space that was a front porch but now its a living space. No insulation anywhere. The left wall is open with lattice covering the opening and cinder block wall to the basement on the right. The floor is not insulated and dirt base. Im not sure if i need to foam board the floors thats above and foam board the cinderblock? It has no mold but its a living space that needs insulation 😵‍💫😵‍💫

Does it help to add gypsum to clay soil?

Hey Michael, got a question for you. I have a venter crawl space that sits on a concrete slab and has block for the walls. I'd like to insulate amd encapsulate. What I can't understand. Do I first attach foam board using Hilti nails, then encapsulate over the foam? Or do I encapsulate first then attach the foam? If the latter, how would I attach the boards over the barrier?

thank you! I already have an encapsulation that needs to be redone!!

After learning what this is and what it does its now on the "no squish" list....helpful little horrors. I only see them in the spring and fall when its generally more damp and gets chilly at night...i should probably invest in a dehumidifier

Whenever I’m in a situation such as this I always ask myself, “What Would Crawlspace Ninja Do?”

My main basement maintains a consistent 45% humidity level. An attached addition has a crawlspace with a 2 ft. by 3 ft. pass through. The crawlspace level is 65% humidity. I want to try a fan first placed in the pass through opening. Should I set the fan to blow INTO or OUT of the crawlspace? Thank you.

Bought a manufactured home last year, finally ripped out the carpet in the living room and replaced it with a vinyl floating floor and under that a very thick quiet mat moisture barrier. Once summer hit the subfloor under the vinyl has started warping. o_0 I am assuming the vapors can no longer escape due to the moisture barrier and is causing water damage on the subfloor causing it to warp. Before I replace the subfloor I need to figure out how to stop this from happening again... I am hoping just removing the moisture barrier under the vinyl floor will stop it... but idk.

You should also talk about the air lock problem, i installed a pump myself, and i did not know about it... untill the pump jam. Took me a bit to sort it out!

I live in a house that was built in 1830. stone foundation. no vents, no plastic, no insulation. My house smells so bad. Ive been living there 3 years and I cant stand it. Im at a loss

Your videos are very informative and greatly appreciate the info. However, centipedes are not insects. They are arthropods belonging to the class Chilopoda of the subphylum Myriapoda, an arthropod group that also includes millipedes and other multi-legged creatures.

Should I go with 10 mil or 20 mil vapor barrier?

Great advice well presented. Thank you.

Nice video!

Great, honest video!

Is there anyway I could contact you personally? I just started my business. I went through certification, but I’ve got a couple of questions about mix.

Cellulose any day. Glass fiber is not air tight. Natural convection destroys its thermal resistance in the loft attic.

I have a basement with an attached crawl space that has about a 3ftx3ft opening, but the crawl space is really just a shorter part of the basement. It is finished with concrete and block walls just like basement. We’ve never had moisture issues until last year when we had a roof leak that was dripping behind the wall down into the crawl space. Since then we’ve been having a hard time keeping basement/crawl space dry. My husband sealed the floor and walls in the crawl space with randon seal and we run a dehumidifier in the basement but it doesn’t get levels down in the crawl space area. I got a fan to put into the opening that has 2 smaller fans built in that can blow in, out, or exchange air. Should I blow dry air into crawl space, suck the moist air out to blow into the basement with the dehumidifier, or have one blow in and one suck out?

Looks good compared to my 125 yr old stone walls which are covered in dust,dirt, and ? Plus I'll be on my belly trying to do this.

Thanks, Im going to give this a shot myself first, had a water main feed line leaking for a while but didnt know until it burst. Crawlspace is soaked and the plumber indicated some mold growing. My first thought was to get everything dry first, then clean, then put something on to help prevent regrowth. I hadnt thought about having to replace the insulation until I saw your other video that mentioned the paper backing retaining mold and spores. Thanks!

This guy is a pro

Does encapsulation reduce noise from outside sources?

Does insulation go under or over the vapor barrier on walls

very good video! Question; my wooden floor is sagging when I step between supporting beams that are laid approximately 3 feet apart on the concrete floor apparently, there are not enough of support beams between the concrete floor and wood floor. I think they should have laid those supports every foot or so to give it more stability, then put the wooden floor on it and that should made it really solid floor. This is a cottage so previous owner did not invest lots of money in quality work. because sub-floor is poorly constructed and there is a quite of a sag when you step between sub-floor beams, my question is - can I inject the spray foam between existing floorboards and concrete surface by drilling through the floor boards in order to help stiffen the floor? I am thinking that maybe drilling the holes in the floor on every couple of feet between the supporting beams and injecting the foam will stiffen the floor, then I would lay over this a new hardwood floor. any pros or cons?

I feel like it’s useless to kill mold. I have to take environmental tests that cost $1100 and the mold will still grow no matter how it may be toxic to us. Ugh!

Hey there! I really appreciate this video and how you frame alternative options besdies (extremely expensive) encapsulation. It looks like the Vollara FreshAir Cube isn't available new anywhere. Do you have any other air purifier you would recommend for a musty-smelling crawlspace? Or do you know where we can purchase a FreshAir Cube? Our master bedroom is directly above our crawlspace and the smell from our vents keeps my wife up at night :(

I think of it as something that is very well worth it if you are LIVING in the home for a while, not something you'd do right before selling. So it's not about adding value, but adding quality of life while you're in the home. Also, if you have issues, it's going to further degrade the integrity of your home as time goes on (mold, rot, damage to wood floors, etc.). My CS encap eliminated an insect and rodent issue that nothing else would fix, the house stopped "swelling" in the summertime (doors sticking, cracks forming, etc.) and it uncovered some water intrusion that had rotted about 8 feet of rim joist/sill plate that had to be repaired. It was worth every penny (or if you DIY, every back-breaking moment of work), but I plan to be here a while. Not everything is about resale. Consider that you're extending the life of your healthy home, which will increase in value over time, which is also a return on the investment.

Ah I think your interpretation of the data during the colder months is wrong. There’s essentially no difference between all of them. The error bars overlap each other essentially every single case. There’s no statistical difference.

Hi there sir, I live in Long Island New York near the water, but we rarely get any floods here; but also because we are so low, the foundation is mostly wet. I'm brought 2 foundation companies to check out my crawl space And one of the companies told me to eliminate all access windows and leave only 1 and make the crawl space air tight, and put a moist barrier on the ground, foam spray on the walls and installation on the ceiling. The other company told me to leave all 3 windows and put automatic ventilation windows with a commercial dehumidifier and a sub pump, and he also told me to put the same floor barrier with foam on the walls, but he told me I don't need Insulation on the ceiling. Which one should I do? Also the first company told me that I should replace all brick support columns underneath with metal adjustable rods and the other company said to leave the support as it is. They are so opposite and I don't know what to do, and they are both experts with lots of years of experience with high reviews. What would you recommend sir?

Should there be hangers attaching the floor joist to the rim joist?

👍

Thank you so much!! I was considering doing this within dehumidifier but now I am going to put in the dehumidifier as a backup. 😊
