Congrats on the house! and welcome to the area!!

It would have been a good idea your drain (when you made it) to see it. Thank you ,good job.

I just want to say thank you for all the education you have provided me. We went from owning a stick built house with a regular basement to a mobile home out in the country. When I built the skirting for the crawl space i added 6 mil poly to the ground as per the recommendation of the building inspector. I also fully insulated the skirting walls to R14 and vapour barriered them from the inside, to keep the house from getting too cold underneath in our brutal winters. Looks like I got those things right! Here's where I went wrong. I opened up all my vents this summer and turned on the heavy duty fan (our first summer here), its been very humid and i wake up the last couple days and humidity levels have soared to 99% under the home. I have a wireless temp and humidity sensor under the house so I can monitor readings easily. Off to KZread I go to figure out what I can do! I watched your videos for hours last night. This morning I put a dehumidifier underneath the home, closed up the vents (insulated as well) and started dehumidifying and to my pleasant surprise I've dropped 10% in just a half hour and still dropping. Thank you so much for posting all these videos online, you literally protect peoples homes and personal health by providing this service. cheers!

+John Dove Great question. We like the dry air coming out of dehumidifier to point towards the back of crawl space.

I know a builder whose own one-story house (that he built) had excess moisture in his crawl space. He had a crawl space dehumidifier installed, much like in your videos, and after several months, his wood flooring became warped and squeaky. He said his sub flooring, etc got too dry. He disconnected the dehumidifier, replaced all his flooring and installed a couple of foundation vent fans. Location is Lebanon, TN. I love your videos, but correct solutions to crawl space moisture seem so house-specific. Hard to judge what to do.

Absolutely, if you get a dehumidifier that does not have a humididstat then you could be in trouble. We prefer to keep the crawl space humidity level around 50%. If you start getting below 40%, you'll risk wood beginning to crack. Thanks for pointing that out.

Thanks! Fortunately, my vented and unsealed crawl is nice and dry, but Spokane has the wet season in spring, and we get dry heat. Winter is dry cold. One thing: Guys...just do NOT insulate your crawl cieling/home floor. Wood breathes and can dry-so long as you don't put something all over it to trap moisture! So the only insulation I have is in the crawlspace vents and door, but it is held in place by anything, so air can get around and under it. It gets decently wet in spring, but dries quickly and I have zero mold, zero rot down there. Inspector approved. Again-we get hot and dry from July-October, so the home has time to warm and dry. I am looking at encapsulating it due to this part of the country having super high levels. Otherwise I would leave it alone.

The only time I have seen this work is if the fan is used to draw conditioned air down out of the living envelope and through the crawlspace. If using fans to just draw air from outside you just end up with the fans running constantly and it pretty much raining in the crawlspace from spring throughout the summer due to the high outdoor relative humidity in the Ohio Valley.

Yes, you can use one dehumidifier as long as there is good air flow, but make sure your dehumidifier is sized properly for the space, otherwise it may run nonstop trying to keep the three areas at the humidity level you have set. Keep in mind that if you're creating air flow between the three areas, you will end up pushing the conditioned air from the basement as well, and end up paying to condition two spaces you won't be spending much time in. The Aprilaire dehumidifiers we sell will run more efficiently and less often than your typical box store dehumidifier.

Great coverage of issues. What does a homeowner do if your crawl space "floor" is in flood zone AE where open vents are required per FEMA? The building floor itself is well elevated above the required base elevation, but the crawl space is enclosed, thus requiring the open vents.

2100 sq. foot crawlspace encapsulated in Southern Illinois where we get the extreme of all 4 seasons (sometimes all in one day!) If I have a crawl space ventilation fan pulling 240 CFM (thus creating a negative pressure in the crawlspace) am I better served with the dehumidifier in the house since that is largely where the crawl space make up air would come from or in the crawlspace itself or both? I feel my humidity levels are typically a bit high in the house as well so my logic is to make that comfortable then pull that dehumidified air into the crawl.

@billmiller2125

4 жыл бұрын

I have an interesting application...I had a house built in which I was trying to control crawlspace humidity by pouring a slab floor in the crawlspace...and then coating the floor with some concrete sealer. The block walls of the crawlspace and bond have been sprayed with 2" of foam. It is not a conditioned space (yet) and I still observe humidity levels near 60% in the summer (a good 20% higher than in the conditioned space in the house). From this, I see some minor buckling of my hardwood floor. I live in a high water table area, so a humidity source is always present around and under the house. Due to my proximity to a river, I am required to maintain flood vents (that can open during times of flooding) instead of a normal vent. With my electronic humidity meter, I find that my opening in the block wall for the flood vents, and the flood vents themselves, are a large source of humidity entering the crawlspace, hence I'd like to 1. seal the block wall cavities that are open...and 2. create a removable seal/insulator for the flood vents. I'm thinking I can spray foam the block wall cavities to close them off....but I was thinking of using some 4" thick closed cell foam to create a removable insert to seal the flood vent. I plan to have my HVAC guy extend furnace ducting into the crawlspace with a cold air return to make this space "conditioned". I would appreciate your comments...especially your thoughts on a removable feature to seal the flood vents. Thank you !

You mentioned that having vent fans wouldn’t make much of a difference because it is pulling humid air into the crawl space and then back out. That makes a lot of sense. If I do not have the budget to install new barrier/sump pump/dehumidifier system, is there a way to make the vent fans more effective? Possibly having the vent fans ALL moving the air out of the space rather than through? Our house is pretty humid in the summer, and although the crawl space doesn’t look too bad, I know that allowing it to continue in this humidity until I am able to fix it properly could cause even bigger problems. Any temporary quick fixes you can recommend?

In this particular crawl space, the BEFORE pictures showed the vent fans that flow THROUGH the crawl space. We recommend the Lomanco vent fans that give negative pressure, pulling the air out only. There are not any fast fix it recommendations. The standing water will not be able to escape without trenches and a sump pump. The moisture and condensation will occur unless you have a dehu and vent fan.

If there is a place for that moist air to go after you heat up the materials it should work good but unfortunately I am not familiar with your climate. Sorry, I hope that helps.

Spleujo, are you talking about "humidity" or "relative humidity"?

You should install a water management system anywhere there is water intrusion. I hope this helps!

Guess I missed it but when you encapsulate a crawl space do you also close ALL the old vents or do you leave one or two open for some kind of ventilation . Id think to close it up tight . Looks like you guys do a great job . Im thinking bout using foam board on the ground under my vapor barrier along with the R- 10 foam board along the outside walls . WOuld that be overkill to do that Love the idea of the de humidifier & sump pump

We install a ventilation fan blowing out in 1 vent and seal the rest. For the foam board, make sure that it is rated for ground contact!

Thanks much . I'm planning on doing this to my home before I sell it . Cant be leaving the stalactites hanging down cause I know how bad I hate being under there with them . You are the first company I've seen on youtube that seems to know what you're doing . Thanks for your help !!!

Great video! Question. I noticed the insulation on the walls stopped short of going all the way up still showing several inches of the block at the top. why is the insulation not run all the way to the top of the block foundation? I only ask Because I’m going to attempt to do my own. I only have a slight humidity issue in the summer. I’m hoping this will decrease that issue?I don’t think you come to Illinois? 🤔

We dont come to illinois sadly! we stop 3 inches below to allow for termite inspection, that will depend on your local building code what you can do. Insulating walls will help but to truly decrease humidity you would need a dehumidifier. Hope this helps!

Do you always add a sump pump as a precaution or only if there is water actually getting in?

Im wanting to encapsulate my crawl space. There is a crappy black barrier on the raw dirt already so im wanting to install over that. My question is how do I go around pipes on the walls?

i have a question about craw space dehumidifier, ours seem like it is between at 63 and 65 percent, the dehumidifier fan is set to auto, my question is should we turn fan to on to keep moving area to get rid of the moisture? not sure why it isnt going lower then 62 percent. thanks so much

Usually when the relative humidity isn't going down, it's either due to improper insulation or the dehumidifier coils not functioning properly. Without a thorough inspection, we can't really give you an honest or accurate answer. We hope this may point you in the right direction though. Thanks for watching! Have a happy and blessed day.

What determines whether you trench inside or outside the wall for water drainage issues? Do you drill weep holes in the concrete block to drain the block to the french drain? I saw that on a hydro armour video.

@CrawlSpaceNinja

6 жыл бұрын

Great question. Usually cost is the determination. Easier and less expensive most of the time to do it from the inside. Weep holes are useful when you have a lot of water filling the block and it is coming in faster than it can drain out.

Crawl Space Ninja what if we did trenching all around the outside of the home to help? Would weep holes still be necessary?

@CrawlSpaceNinja

5 жыл бұрын

@@37south14 It would be up to you. We choose to not do weep holes in order to make sure water does not come into the crawl space too quickly for the drainage system to handle and cause the plastic to float. If your exterior drainage is taking care of the majority of the water it is likely you won't need weep holes.

Do you have a vapor barrier that also blocks radon gas? My crawl space has large white rocks covering the floor. Would the rocks puncture the vapor barrier?

No we do not have a vapor barrier that can block radon, we do have underlayment to protect from rocks. diy.crawlspaceninja.com/?s=underlayment

My crawlspace is dry 9 months of the year in Anchorage, AK. During July, August and September it is about 70% humidity. There is a fan mounted to the rim joist which pulls air from the house, not the outside, and exhausts the air outside during those months, but the humidity does not decrease very much. The rim joist is not ventilated and no outside air flows into the crawlspace except from the house. Any suggestions?

Is your crawl space encapsulated? We would recommend a dehumidifier to continuously control the humidity year round and an encapsulation would help make sure the dehumidifier is not overworked. It is possible that your living space air is humid and shouldn't be going into the crawl either, but you won't know for sure without a humidity monitor.

Is it a good idea to put peR gravel on top of the vapor barrier. Jim

@CrawlSpaceNinja

4 жыл бұрын

No, it would be hard to go in and out if you need any work done. in fact there are times when there is gravel we have to either install an underlayment or double up on the vapor barrier to make sure it doesn't get punctured.

Can the Lomanco fan be throttled with a generic fan speed controller? The code here in CA only requires 1 cfm for each 50 sq ft of encapsulated crawl space. I am encapsulating a 400 sq ft space, so need less than 10 cfm. If not, any recommendations? Thnx!
