DIY Mold treatment (by Jason [VA]) Posted on: Jul 10, 2018 4:34 PM
Message:

Today I was at a property conducting a post move out inspection where I noticed the subfloor was extremely wavy in two rooms. I pulled up the laminate flooring and found the particle board subfloor was pretty badly warped.

I went under the house to investigate and found that most of the insulation was moist and covered in a thick layer of white mold. It formed stalactites of this mold in some areas. I don't recall ever seeing moisture underneath of this property before and I can't find any smoking guns quite yet, but that's another issue.

I'm going to remove all of the insulation and then treat the mold. Can anyone recommend a good DIY mold killer (I was hoping for something a bit more potent than bleach and water).

After it's treated I'm going to add automatic vent fans under the house and will replace the vapor barrier and insulation as well.

I've documented the water meter's reading so I can compare it in 24 hours to see if I have an underground leak somewhere. --73.177.xxx.xx

Go to Home Depot and get concrobium and you can fog the area and get rid of the mold --68.32.xxx.xxx

You will also need a professional Full Face Mask with a filter rated for Mold - 100%, not a 95% or less filter with only a small membrane but a thick filter.... Mask will cost $100-$150 and the filters are around $20-$30 a set. --47.156.xx.xx

Yes be careful around this stuff - ventilate now slowly, same company made a product called -mold armor-, I have been using peroxide in my shacks, this could get worse before better once you remove the insulation, take it out to dry in the sun - the UV will assist killing whatever you have but cats will like it if you have strays around the place. --76.188.xxx.xx

Another vote for Concrobium. Once that is dry, we also paint over it with Zinsser Mold Killing Primer. --67.184.xxx.xxx

+1000 on using a quality respirator. A guy I know was rehabbing an old mobile home with water damaged floors. He got so sick from the mold he had to stay overnight at the hospital. --96.234.xxx.xxx

Jason,

Bleach helps but does not kill mold. You need a MILDEWCIDE such as Concrobium or such. We use a hospital grade cleaner which includes a mildewcide from our local janitor supply house.

I'd never heard of using peroxide. How effective is it? It would be nice to know of something that works well before the need arises (know what's needed before I encounter the problem). --71.213.xx.xxx

Used concrobium last fall after discovering a water heater leak under stairs. Several days of spraying concrobium, cutting out drywall/insulation, eventually primer with mold inhibitor primer and a last coat of concrobium. Looked good in the spring and will be back to check it shortly since it is our vacation condo. Note to self, the next time the cleaner sends a photo of a mushroom growing in the front hallway, have him check under the stairs for the cause! --24.61.xxx.xx

For years I've been spraying mold with a solution of 1/3 water, 1/3 hydrogen peroxide, 1/3 white vinegar. Hasn't failed me yet.

Good call TW, and WAY less expensive! Water free, vinegar negligible, and Hydro-perox fairly cheap at any pool supply store (Used for cleaning the filters). After we moved from our residence with a pool, we had a gallon+ of hydro-perox left over, and I found that cutting it half with water cleaned a LOT of stuff 'whistle-clean.' (toilet, drains, garage floors, concrete walks, floor grout, etc--even once the blackened bottom of a fry pan!) Never thought to add vinegar but couldn't hurt.

And YES to well ventilated (use a fan) and yes to the mask too. Mine as borrowed so I never knew it cost that much! --108.87.xx.xxx

Thank you all for the pointers. I have a high quality mask that I've used on other projects, so that isn't an issue. Also, I bought Concrobium and will be following up its treatment with mold foggers soon thereafter. --73.177.xxx.xx

Hydrogen peroxide also took out black stains in oak flooring that I believe was puppy pee. Put white cotton towels over the spots, keep wet with the peroxide for several hours and let dry. It will take the finish off, but we sprayed the area with a couple of coats of spray urethane before scuffing and sanding for the new urethane it needed anyway. --64.222.xxx.xx
