Crawl Space Mold Removal Tips | DIY Mold Remediation Crawl Space


Hey there Michael church with CrawlSpaceNinja.com and today I want to talk to you about mold removal in your crawl space. Did you know that 90% of the people who call us think that there’s no mold in there crawl space although they have high humidity and standing water? Then when we go out to do an assessment on the crawl space we find mold everywhere to the surprise of the homeowner. Now this could be because some people don’t know how to look for mold or even if they saw it they wouldn’t know what they’re looking for. So I want to give you a little tip on how to look for mold in your crawl space that may not be jumping out at you. For example you know if it’s not all black and fuzzy and all that you may not exactly know what you’re looking for take a really high beam flashlight like an LED light along the joists take the light and put it right up against the joist and shine down the wood you can do this on the subfloor as well and you want to shine the light down the wood and put your head right behind the light and look and what happens is if you have a little bit of mold getting started or even something that is kind of a light in color like a light gray mold or something like that that’s hard to see it’ll show that up really good it’ll give you an opportunity to see if there is something growing on the subfloor now of course there is no substitution for an actual mold test so what we recommend also is that you use a mold test in order to identify what type of mold you may have and also how much because all crawl spaces and all houses have mold in it what you want to see is do you have dangerous molds at high levels so the only way really to do that is with a mold test okay so if you are concerned about mold in your crawl space and you’re not sure if you do have mold or not a great way to handle this is with our DIY mold test this is something that we make available on our website very easy to use and you actually send it off to a lab for a full result so if you’re looking to get an inexpensive mold test done here is a great way to do it is with a DIY mold test kit okay so what do you do if you find mold in your crawlspace there’s a lot of misinformation about this in fact there’s a video that I recommend you watch and it’s going to be right here it’s the five crawl space repair mistakes that most homeowners and contractors make and it will talk about some of the ways to make sure that you’re preparing the crawl space for mold remediation you also don’t want to use any kind of bleaches or anything like that I know that’s a very controversial thing some people all just throw bleach on it well a few things about bleach number one is it still not been proven to effectively disinfect mold on porous surfaces and of course a porous surfaces wood so the other thing is bleach is very very destructive to whatever you put it on including yourself I don’t know if you’ve ever been exposed to bleach but you certainly don’t want to be exposed to the fumes of bleach another thing you want to make sure of before you start your mold remediation or mold removal project is you want to make sure that whatever’s caused the mold you have plans to correct fairly quickly you don’t want to go in and remove all the mold wait a month or two and whatever caused the mold is going to bring it right back so if it’s high humidity standing water a plumbing leak whatever the case may be make sure you address that and dry out the crawl space because the wood can be absorbing all that moisture so you want to get a moisture level of the wood under probably 15% maybe even closer to 12% and you can get a moisture meter like a surface moisture meter or a probe moisture meter to check the moisture content of the wood before you get started a couple of other notes I want to talk to you about is is what they call protective equipment PPE you want to make sure you have a mask and goggles and you want maybe a Tyvek suit depending on if you’re sensitive gloves and of course safety things like that you also want to put the crawl space under negative air and perhaps use what’s called a HEPA air scrubber because once you start attacking that mold it’s going to want to survive so it’ll start to spore if you spray anything on it or you start rubbing it off mold has a tendency to want to move to another place so you certainly don’t want it moving up into your house you put the crawl space under negative pressure you can move that mold spore out of the crawl space instead of allowing it to go up inside your home there’s a couple of different options that people choose when they’re addressing mold they’ll just spray it with a disinfectant and not remove it and then they’ll also want it removed and disinfected and then the third option is they’ll want it removed disinfected and then a protectant put on to ensure that mold doesn’t come back keeping humidity low is in fact a protectant but they actually make some really good compounds to spray on the crawlspace to ensure that the mold does not return and I’ll get to those in just a second but the first thing you want to do is if you’re going to address the mold and remove it we recommend the Anabec System that is a wonderful peroxide based system that attacks the food source of the mold and also disinfects the mold it can be used for bacteria viruses different things animal damage if you’ve got like a raccoon or a possum that got in there and destroyed the crawl space and stunk could place up it’s a really good product for that some of the other ways to physically remove the mold would be to use a HEPA vacuum cleaner now these could probably be rented at Home Depot or Lowe’s and if you had a shop vac you can add a HEPA filter to it so just using rags and brushes with a good disinfectant is the best way to attack surface molds and one other thing just remember that applying or just spraying a disinfectant on mold does not make the mold go away here’s a few pictures of a house we just did old farmhouse the homeowner was not interested in visibly or physically removing the mold they just wanted us to apply disinfectant to kill the mold okay the last product I want to tell you about is the Anabec X70 and it is a water intrusion protectant as well as a mold preventative so it actually stops moisture from penetrating into the wood kind of like sealing the deck or a stain on your deck does so it’s a really good protectant to keep humidity out of the wood and different things like that it also uses a silver nano technology to kill mold spores I don’t know if you know this but silver is a natural antifungal if you want to put a protectant on your crawlspace to make sure the mold doesn’t come back the X70 is what we use now one last thing I do want to say about the X70 product is it’s not a substitute for dehumidification so if you are still high humidity if you’re over 60% you want to make sure you control that humidity okay well that’s all I had to share with you today I really appreciate you watching this video and I hope you liked the video and share it and subscribe to our channel and I’ll see you next time thanks again and make it a blessed blessed day thank you very much

    As a new home-owner, I'm glad to have found your channel! Here we seem to have a yellow powdery-looking mould that can grow in damp soil – it looks creepy! I'm becoming convinced that ventilated basements are not the best idea, especially where summer humidity can be high. I know that dehumidifiers can be effective in encapsulated crawl spaces, but could HRV or ERV systems also be effective (perhaps in conjunction with a dehu)?
