Mold Abatement in the Basement
Mold can be serious business, but I think that the hysteria about it enters the realm of being big business. Mold education is always a more effective first step than panic. Because the house we bought has some moisture issues, I looked into educating myself about mold and moisture problems and found some excellent resources that helped me feel very good about managing things in our new place. First, I read A Brief Guide to Mold, Moisture, and Your Home, a PDF from the U.S. Environmental Protection Agency (EPA). Then I took an online mini-course: Introduction to Mold and Mold Remediation for Environmental and Public Health Professionals from the EPA. I was able to complete all 9 chapters and all of the tests in one night. (This course is for general education, and is not a certification.) The EPA also has this great chart for cleaning. Home Depot and others sell mold kits, but proceed with caution. Mere traces of mold spores are expected; mold is all around us outside. Indoor mold growth (beyond a small, normal amount like in the fridge or bathroom) is really the problem. Many people think that bleach is the default mold cleaner, but this is not correct. While bleach is an effective mold killer on non-porous surfaces, it is not effective on porous surfaces. In other words, it will kill mold on a tile floor, but unless your grout is sealed that makes part of your floor porous. Drywall is also porous. I don't think bleach is best for anything ever so I wouldn't even consider it for non-porous surfaces. Hubby uses it to clean his home brewing supplies and won't change his ways, but I personally don't ever use it. Here is some more info on bleach & mold and why bleach is not the best choice. So, with bleach out as an option, what is left? Here are the steps that we took:
We are at about 3 months out and none of the mildew has returned! On to the pictures… | |
Before--Large Room in Basement
Mildew is primarily from the gutters not working and thus water collecting near the house. Plus we've got general filth and ickiness down there. In these pictures, brownish spots are filth, blackish spots are mold. The room has much more grime that it does mold. But, it still has to be dealt with.
After Mold Remediation
Walls: after steps described above. Floor: cleaned with Murphy's Oil Soap and my mother-in-law's amazing floor electric scrubber. The goal was to get it clean enough for the movers to put down boxes. At some point, all of the flooring in the basement will be replaced. I would like to do it soon, but we have bigger priorities and an area rug can help cover it up.
Before--Other side of the big room in the basement (leads to the second kitchen which is a scary place that we have only done demo work in)
After Mold Remediation
(The stairs are very ugly because of chipped paint. I just brought home floor paint samples to decide on for painting them. Yay!)
Before: Other view of the big room and the craft closet
Before: Close up of the craft closet. This is the worst mold in the house. We'd seen much, much worse in other houses so we weren't daunted by this. But, it is certainly was enough to indicate a water problem and enough to warrant careful abatement. The mold here is from toilet leak in the bathroom on other side of wall that went on for so long and was extreme that the moisture rotted the bathroom subflooring and rusted everything metal nearby. Someday I'll share those scary pictures.

Unpacking in the craft closet
Unpacking in the big room. The basement is not heated, so we haven't done much down there but unpack some things and make sure that everything is up on blocks and nothing touches the walls until we make it through a few more months with no moisture problems. So far, so good! In theory, we could play video games down there now (that is what it is set up for) but it is too cold.
Come summer, hopefully it will feel refreshing down there and we'll start some real work.

When it comes to removing mold, it can be dangerous; that is why it is advised that your home or business undergo a professional mold removal. California residents, at least most, are unfamiliar with how to properly remove mold.

In extreme situations whereby you might find extensive water damage mold after the cleanup, you might opt to enlist the help of mold removal companies which have professional experts to manage black mold removal on your behalf.

First commenter, I am so glad that since I am not a California resident my work stands. LOL! This comment cracks me up.
Dear Readers, obviously consult a professional if--after developing an educated opinion so you at least can be a prudent shopper--you are not comfortable remediating yourself (for example things high on the EPA chart that require special clothing and containment). We saw houses that we wouldn't touch with a ten foot pole in our house shopping journey. This obviously was not one of them.

teamdwms: Oh, wow! This looks great. You guys did a great job on restoring the area and cleaning everything back up. It is always smart to hire the professionals because if the mold spot isnt completely cleaned up and you paint over it - it will just bubble up the paint and resurface to create more problems in the future.

We are almost six months out with no problems, so it seems we did the job right!
