Lingering, Hidden Sources of Indoor Mold Exposures
If you are someone who has dealt with mold or environmental illness, you know firsthand how difficult it can be to finally feel safe and secure again in your home, especially if your home is where you became sick in the first place. Even after a major mold remediation, it is easy to sometimes feel like you are just one step away from another mold catastrophe or from finding that one place inside your home that was not fixed and cleaned properly and that still triggers your symptoms. One statistic a heard from a very well-known naturopathic doctor is that one out of every three of her mold patients remain symptomatic due to failed or insufficient mold remediations. They thought they had taken care of the mold problem but remained sick and not improving until additional cleaning work was done, or they found the mold source that had been missed the first go around.
One in three odds that a mold remediation will fail is obviously a very scary statistic, especially since the cost of the work can be large and usually comes with zero guarantees or free do-overs attached. I know that when I returned to our home post mold remediation, I still felt symptomatic and like my throat and sinuses were closing and swelling when I would enter some rooms or be around certain belongings. At the time, I felt like my body had transformed into sort of a divining rod for mold. One whiff of a musty room or a piece of furniture that smelled “off”, and I would feel mold symptoms and anxiety build inside of my body. And, while I do believe that a lot of what I was feeling was brought on by “mold PTSD” and the fight or flight response triggered just by being back inside of my home at the “scene of the crime”, so to speak, where my life and my health had taken such a horrible downturn, I also know now that there were some lingering, hidden locations where I was still having mold exposures. Those areas turned out to be small and not major leaks or water damage, but they were exposures all the same, and my body, because it desperately wanted to heal, was NOT having it.
How Did I Know Where to Look?
It took almost 6 months for us to fully remediate our home and to make it safe enough for us to move back in. We literally gutted almost all interior walls and ceilings, and replaced the HVAC system, the ductwork, and all of the attic insultation. We also got rid of most of our furniture and belongings. We redid roofing, gutters, and downspouts, and even replaced our garage door. (Note: Now that I know so much more than I did back then, I do NOT think it is always necessary to discard all furnishings and belongings. While each case is different, many things can be successfully and safely cleaned.) In a sense, this made it easier to find where I was still reacting, because reentering a clean slate and an empty home made the rooms and items that were still irritating my body quickly apparent. More importantly, though, during the environmental inspection and remediation processes, I learned a lot about two important pieces of the puzzle when searching for the source of a mold exposure:
- Where mold likes to grow—anywhere there is moisture, less light, less airflow, and organic material to feed on;
- How my body reacts to mold when I am around it—throat closing, sinus pressure, highly agitated, and almost instant onset of brain fog. (Note: These are just a few of my symptoms. Everyone who is susceptible to mold illness reacts to mold differently and exhibits different symptoms. HERE is a great resource on this website for more information on evaluating your symptoms to see if they could be a result of mold-triggered illness.)
Overtime, I was able to use those 2 puzzle pieces to put together where those lingering exposures were occurring. The cool thing is that when you know where the exposures are, you can usually use tools and proven methods to clean or fix them. Then, the result is not a failed remediation, but a home that you and your family can live in as you regain your health.
An Inconvenient Mold Remediation Truth
Before I move on to telling you about where those hidden exposures were for me and my family, I do want to address sort of the dark secret of any mold remediation no matter who does it and how great that person or company is at their job: If you have mold or environmental illness, it sometimes takes more than the initial mold remediation to fully take your home back from mold.
In other words, the best remediator can come in and do the best job fixing and removing the mold from your home, but after that, you will need to practice mold hygiene and mold maintenance to continue to progress yourself forward. Because your body is now sensitized to mold, avoidance in all forms will be your greatest ally. The effort and the amount of work required will definitely vary from home to home, person to person, and depends on how big the mold problem was and on how long it went on in the home, etc. No matter the details, though, I believe it is important to begin cleaning your home and maintaining your home with preventing mold in mind. The silver lining is that you discovered the mold and discovered it was making you sick. You have a leg up, because you know your enemy, mold. So, now you will need to take it seriously, and to look for and address it wherever it continues to pop up and affect your health.
Potential, Lingering Sources of Mold Exposure in Your Home
This leads me to my list of places where I encountered mold in our home after we had moved back in. None of these places were areas where we looked for major mold problems. Some of these places would have never even occurred to as potentially problematic before we got sick. Maybe if the mold had not taken us out, they would have never bothered us. I guess I will never know. The point is that when we returned, I discovered them because one or more of us was reacting and still had lingering mold symptoms, even though our home was now considered “safe” by environmental mold and mycotoxin testing standards. My hope is that by sharing my experience, it will enlighten anyone who is at home and still struggling to get and feel well. Reading this list may give you your “Aha Moment” that leads you to the source of the problem. Maybe I can help you save time spinning your wheels.
Places in Your Home Where You Could (Still) Be Getting Exposed to Mold:
- Your refrigerator water and ice dispensers. How many times, if ever, have you looked closely at where you are getting your ice and water? If you haven’t, do yourself a favor and take a good look. If there is mold growing there, and you are using those dispensers daily, they need to be cleaned. HERE is my post on how to do it.
- Your bathroom and kitchen sink faucets. This can be a big source of exposure for children especially. My kids used to drink out of our bathroom sink when they brushed their teeth or woke in the night. I never thought to look at the faucet until I saw my son drinking from it. His GI symptoms were still terrible when we moved back in. When I looked, I found that the aerator on the bathroom faucet was black with mold. When my husband opened and removed it, I could not believe the gunk. After I cleaned the kids’ faucet, I did our master bathroom and kitchen sink as well. Now each time I clean, I also clean the underside where the water comes out to prevent this from happening again. I steam blasted the aerator to clean it and then use the EC3 Spray on it weekly to keep it clean.
- Bathroom/kitchen sink stoppers and drains. How many times do you pull up your sink stoppers and see hair and black gunk on them? Well, not only is it on them, but it is also is the drain itself and can even be in the pipes. If you are leaning over your sink to brush your teeth and wash your face and feeling mold symptoms, this is usually your culprit. It is a good idea to treat all your drains once per month with a enzymatic cleaner that dissolves hair and mold. Hydrogen peroxide is also a wonderful way to tackle this problem. I will have an in-depth article about this soon on my BLOG.
- Refrigerator drain pans and coils. A refrigerator can actually harbor a lot of dust, mold and bacteria, that you never see. Home and environmental inspector Jeff May clued me into this in our interview. Many people do not realize that when your refrigerator fan turns on, whatever is on the coil and in that drip pan is blowing all over your kitchen and into the air in your home. Follow the manufacturer’s instructions to access the coil and HEPA vacuum all of the dust off of it and clean it thoroughly. If you have a handheld steamer that can blast concentrated steam, that is a great non-toxic way to clean it. It is also smart to move your fridge away from the wall periodically to check to make sure it isn’t leaking where you cannot see it.
- The undersides of furnishings. I don’t know what kind of a housekeeper you are, but until my mold ordeal, I dusted, vacuumed, and did “normal” cleaning. I never thought to look under furniture. If you ever stored any of your furnishings in an attic or basement before bringing them inside, make sure to turn things over to check them. If there is humidity, dust, and moisture, many times, mold can grow on the underside of wood tables, chairs, etc., and go completely unnoticed and undetected. Then, anytime you eat at that table or sit in that chair, you get mold symptoms. Walk around your home and notice these unseen places. If you see mold growth, not only address it by cleaning the furniture thoroughly with something like EC3 Mold Spray, but also address any humidity issues that could be contributing to the problem in the first place.
- Your dishwasher. Our dishwashers are designed to clean our dishes, but they need cleaning too. Periodically, you need to remove and clean the screen in the bottom of your dishwasher and the gasket around the door. These remain wet and with the addition of food residue can harbor lots of mold and bacteria. If you react every time you open the dishwasher, this is likely your culprit. HERE is my post on some dishwasher hacks.
- Your garbage disposal. Because we put both food waste and water in our garbage disposals, they can become reservoirs for mold and bacteria. Your garbage disposal needs to be maintained just like you maintain any other area in your home. It must also be treated with a cleaning solution designed to combat mold and bacteria periodically. One of the best and easiest ways that I have learned to clean ours is by using our kitchen sink stopper to fill the sink with warm, soapy water and one full cup of EC3 Mold Solution Concentrate. As the sink drains, run the disposal until all of the water is gone. Sometimes, if the situation is more pronounced and cleaning does not get rid of a smell or mold, you will need to replace the garbage disposal.
- Interior framing and ledges around windows. Windows can be sources of condensation and water intrusion. If your windows are leaking, are improperly flashed on the outside, or are broken, they will need to be fixed or replaced. This is a big job and is often looked for by an inspector as a source of mold. In fact, we had to have many of ours replaced. When replaced, usually the window casing and surround is replaced, but the wood frame on the inside of the home is left. If water ever came inside or condensed on the inside of your windows, all of the interior framing around the window needs to be thoroughly cleaned and wiped down with something that will treat mold. If the windows were properly fixed, cleaning will often solve the problem. If there is an ongoing water issue of any kind, the mold will return, though. My advice is to clean the entire surround and frame with something like a peroxide cleaner, Benefect, or EC3 and then watch very carefully for any discoloration or mold growth afterwards. If it comes back, you need to look into where the moisture is coming from and figure out how to solve it. Windows are wonderful, but not when they are making you sick!
Did reading my list turn on any lightbulbs? Did it make you go investigate and find a moldy culprit? In no way is my list meant to cause more anxiety and fear. I hope it will cause action and bring renewed health. I wholeheartedly believe that a home can be made safe for a “moldy” person. I made ours so, and believe that with enough knowledge, anyone can do the same.

Hi i’m glad I found your website. My husband and I are moving into a new to use house (1958) next weekend. We demoed the house down to the studs, bare floor underlay, replaced most of the windows, ( moved 3 large stationary windows), replaced all insulation, blower door testing, new electrical, new plumbing from the hook up at the road throughout the house.. The walls and finish are made to resist mold. I have a great functional med DO. who is helping me. I will certainly read more on your website. I think my husband will appreciate the clarity on the writing.
I have the mold problem and related health issues but trying to cover all the bases is often overwhelming.
Do you have any articles relating to water filtration? Any recommendations for reading and filtration products? We have clean well water, periodically tested, but we are moving to a location with municipal treated water.
I have read on the EWG that reverse osmosis and additional filtration can get most potential problems removed from the water. I am not comfortable making any choices because I don’t really know or understand enough about the systems. I also don’t want to make a costly mistake.
I appreciate your help.
Hi, Judy,
I have an older post on my moldfreeliving.com blog about water filtration, but didn’t write about specific brands. I always recommend whole house filtration if you can afford and maintain it. If not, at least filter all drinking and cooking water. My favorite systems are iSpring 3-stage filtration system, APEC Top Tier Supreme Water Filter System, Woder Water 10K-Gen 3 Ultra Capacity Direct Connect. They all filter flouride, chlorine, and almost all contaminants. I am not a huge fan of reverse osmosis as it remove all beneficial minerals from the water as well. I hope that helps.
I purchased several of the bags that contain activated charcoal that are advertised to rid the home environment from odors, mold, mildew, mycotoxins, etc.
If these activated charcoal contents capture fungal mycotoxins, wont the mycotoxins continue to secrete their toxin if they are not killed even though they may be trapped on a charcoal particle?
I have not had any success with charcoal bags with anything except moisture and VOCs or scents. For fungal mycotoxins, I have not seen the studies for the environmental use of charcoal and if or how the toxins would be neutralized. My assumption is that they are absorbed, or gathered, like when charcoal is used in the body, but not neutralized. If charcoal is used as a binder, it binds to the toxins for excretion, but if those processes are not working correctly, can the toxins can still be recirculated. I think charcoal could definitely be useful, but should also be used with proper mold hygiene and cleaning techniques, like HEPA vacuuming. I hope that answers your question?
Did you do mold testing that showed there was still an issue? Just wondered if these are areas that just need to be tackled regardless of testing results (how you feel shows more than testing, testing doesn’t catch everything).
I found that testing just didn’t cut it for me once I was so sensitized. I really needed to get down to the nitty gritty and consciously practice “mold avoidance” as much as possible in my home. Now that I monitor for things and really limit physical exposures, I am doing so much better. Avoidance truly is the best medicine.
Thank you Catherine for taking the time to write this. Trying to keep myself mold free is the most challenging and frustrating thing I have ever had to. It makes me feel so much better to know I am not alone in this fight. I actually purchased some EC3 spray and even spray it in my air vents each week when the unit is off. I also have been using the laundry version in the washing machine with the idea that it will not only keep my clothes mold free but maybe even the washer since it’s a front loading machine.
Love it! I think it is so important to find your groove and to find the things that really work for you. I have my routine now that includes cleaning, HEPA vacuuming, and checking on places in our home that could have leaks, etc. I have also found that properly treating things proactively is hugely helpful. Thank you so much for writing. I love everyone sharing tips!
