Mold Remediation Steps

We moved out of our house on April 16th, 2011. Spore counts of mold (especially stachybotrys) were very high and our Environmental Relative Moldiness Index (ERMI) was 20.3. [This translates to a 32 on the HERTSMI-2 scorecard] We also had aspergillus, cladosporium and wallemia sebi. It took a long time to get our house to where we could live in it without getting sick. We moved back in on February 10th, 2012.
This remediation cost $40,000

Here are our remediation steps:  (See note at bottom!  This is what we did then but not what we would do now!)

Step 1. – empty the house of all belongings. The only things we left were appliances and built in cabinets. Even those we moved, cleaned inside and out, and decided whether they could be kept.

Step 2. Rip out any building materials that have a hint of mold on them. Growing or standing. We rented a dumpster that would be taken out of town and burned.

Step 3. Clean everything. We used many cleaners in our process. Some had no effect and I would call them useless. It took 10 months to get it to the point where I was not getting sick in the house anymore. This is by far the most time consuming step.

It helps if you have become sensitive to mold. You can become the tester. That was what I did. “Nope. Still can't live here… clean some more.” My poor husband. Those of you who know Mike, know he worked hard on making our house livable for me and the kids. He probably could have lived there through the entire process, but we couldn't. My son and I had gotten very sick in that house and from now on we have to be very careful we are not living in sick buildings.

We did decide that a mixture of 50/50 ammonia to water was the best cleaning solution. Giving the best results after cleaning. I still use ammonia and water for cleaning… luckily for me, I don't react to ammonia. Some do. Some become very sensitive after mold exposure or other environmental toxic exposures. They develop sever Multiple Chemical Sensitivity (MCS) and react to everything. Since the mold exposure, I have problems with lotions, hairspray, perfume, make-up, candles, deodorants and probably more… but I am fine with most plastics, cleaning products and most fabrics.

The most helpful tools were the MaxBlaster ozone blaster, a RIGID shop HEPA vacuum, then later the Miele canister HEPA vacuum and a garden sprayer that we kept filled with our ammonia mixture. The ozone blaster has to be on a timer so it shuts off automatically. When no one is going to be in the house for a day or so… run ozone for 12 hours and let it sit for 4 or more hours after to let the O3 turn back to O2. It kills mold, bacteria and viruses… and believe me if you have mold, you probably have bacteria and viruses too! When they say ‘sick building', that's what you have.

Ozone blast, clean everything with ammonia, HEPA vacuum, repeat. When the house starts to get cleaner… I was able to pinpoint trouble spots in the home. Concentrate on cleaning that area until you no longer react to it. Sometimes I would get sick from cleaning and I had to take time off… or wait until my husband did it. When we were close to done with the house, I was still reacting to the refrigerator, the stove, the microwave, the dishwasher… some we cleaned, some we got rid of… some we replaced. We had to decide based on how easy they were to get into and clean.

Step 4. Put it back together using the most environmentally friendly products we could afford. Vermont Naturals Polyurethane is my best friend. If something wood that I LOVE is still making me sick… I have been putting Vermont Naturals on it… and it seems to be working for me. Some things are just too emotional to get rid of… like my hope chest, and my grandfather's cedar bedroom furniture… Not all wood needs a coat of poly… but some does. This is how I am dealing, not sure it is ‘approved' for mold encapsulation on wood, but it works for me.

Only bring one item into the house at a time so that you can tell what (if anything) is making you sick. I bought three new mattresses and had to take one donated mattress. I had to cover that with mattress covers but we can live with it until we can afford to buy a new one. Thankfully, I am not reacting to plastics or fabrics and I have been able to buy new bedding and couches without being overly careful.

When we went furniture shopping, I was super in tune to whether the place we were shopping for furniture made me react. We spent 4 hours in Huck Finn's Warehouse in Albany, NY… and I felt sure that they didn't have any mold. We bought a floor model… and I sniffed it. INHALE BIG. I have to live with this furniture! CAN I?

We started moving things into the house on February 1st. We didn't move in (sleep there) until February 10th, 2012. It's March 2nd and I am still feeling fine in the house. Everything in the house is new. We have 2 storage units full of stuff that I cannot go near, nor will I allow it in my house.

Some notes:
My husband wore full hazmat suit when he was ripping out moldy building materials. The mask he used was a Moldex 9000 and we got the hazmat suits from the same company.

We used plastic to close off rooms once they were cleaned and we worked our way through the house, cleaning methodically.

If there were an isolated room with mold, that room should be plastic-ed off from the rest of the house so as not to cross contaminate.

The guidelines we used for mold remediation were the ones that were written for asbestos clean up. Although mold is not regulated like asbestos is… it is quite dangerous and should be treated as the bio-hazard that it is.


latest updatesIn July/August of 2014, I started to get sick in my home again. No new leaks, just not feeling well and not getting any better so I did HERTSMI and it came out to be very high.

I found and purchased a machine that eradicates mold and mycotoxins and I am feeling good in my home again – here is a blog I wrote with the before and after test results.

  1. I like that you reminded us first of emptying the house of all contents there. Sometimes the mold remediation process is stalled by keeping movable appliances around the house and it leaves molds on the seams. We will need a cleaning expert nearby to help us out on molds at our house.

  2. Thanks for all this great info! I am totally overwhelmed. I have 2 hi tech machines because I suspected mold but couldn’t find the leak until recently. So do you think running those machines in the home for awhile after we remove the damage and fix it will be enough to stop reacting or do I have to take everything out of the house? I mean I plan to clean everything but just not sure what I should keep etc.

      Yes, Holly. We had a couple of water damage problems since we started using Hi Tech. We just fix the damage, clean and keep running Hi Tech. That’s a good plan. Fix the damage, run Hi Tech. If there is a wall being replaced, it’s a good idea to leave it open for a couple of days to let the Hi Tech air clean inside the wall rather than just tear down and replace. Tear down, wait 2 days (run Hi Tech) and then put it all back together. As for furniture and stuff – as long as air is getting to the area, it is being cleaned so open drawers, closets, books so the air can get to the inside.

      Depending on how close you are to one year with your Hi Tech bulbs and reactor pads, you might want to have new ones on hand to have the most power you can to clean the air. The bulbs and pads do break down during one year – so they work best on Day One and are losing effectiveness by Day 365 with diminishing effects throughout the year. If I were you and I was at 9 months, I would replace now.

      It’s always best to accept that this happened and that it will be fixed and you will be fine. Any resistance and fear is the old way of running from mold coming back to haunt us. There is nothing to fear. I have used Hi Tech for almost 8 years now and never fear mold anymore.

      Think how lucky you are that you found the damage & that you have Hi Tech!!
