DangerBusters™: 25 Steps for Effective Toxic Mold Removal, Remediation, and Abatement

DangerBusters™ Recommends 25 Steps for Effective Toxic Mold Removal, Remediation, and Abatement

Vancouver, Canada (PRWEB) January 24, 2005

Toxic molds and fungi are a significant source of airborne volatile organic compounds (VOCs) that create indoor air quality problems. Toxic mold growth produces dangerous mycotoxins and infectious airborne mold spores which often cause serious health problems to residents and workers.


Eliminating and preventing toxic mold infestation should include these 25 steps:

1. Learn the techniques and procedures recommended for safe and successful toxic mold inspection, testing, and remediation—whether the property owner prefers Â?do it yourselfÂ? or to hire a Certified Mold Remediator (CMR). How? Read mold remediation self-help books and internet mold advice websites, plus get professional mold guidance.

2. Locate and fix all sources of mold-causing water intrusion such as recurring flooding, plumbing leaks, leaky roofs or siding, blocked air-conditioning condensation drain lines, and high indoor humidity (e.g., above 50 to 60%).

3. Inspect and mold test inside, above, and below each water-penetrated ceiling, wall, and floor with a fiber optics inspection device, a hidden moisture meter, do-it-yourself mold test kits or inspection by a Certified Mold Inspector (CMI), and by cutting out small core dry wall samples from the water-impacted surfaces. Look in the middle and back of each core for visible mold growth.

4. Find and locate all toxic mold infestations (visible and hidden) in the entire home or building by thorough, all-around mold inspection and mold testing (with mold laboratory analysis and mold species identification of collected mold samples).

5. Test the outward airflow from each heating/cooling duct register for elevated levels of airborne mold spores. If there is a serious toxic mold infestation anywhere in a building, airborne mold spores from such mold locations will usually enter and contaminate the heating/cooling equipment and ducts, as well as the rest of the building.

6. Replace toxic mold-infested heating/cooling equipment and ducts if the owner can afford to do so. Otherwise, do repeated mold fogging with a mold fogging machine and an EPA-registered fungicide or an effective mold home remedy into the return air duct while the system is running on fan ventilation to deliver the fungicide to internal surfaces.

7. If any residents or workers are experiencing any possible toxic mold health symptoms, or if there is a strong smell of mold, or if there are visible signs of major mold growth anywhere in the building, or if the building tests positive for elevated levels of airborne mold spores, the occupants should move temporarily to a mold-safe place until after successful mold remediation and clearance testing.

8. Occupants moving out should not take any clothing, personal possessions, furnishings, furniture, or equipment until after such items have been effectively mold decontaminated outdoors [or in a clean room built from plastic sheeting] to avoid mold cross contamination of the temporary living or working quarters.

9. Do not paint over mold problems. Mold loves to eat paint as a snack food. DonÂ?t expect to kill mold successfully by using paint containing a mildicide [too mild to kill existing toxic mold infestation] or with a paint primer sold to hide water damage stains.

10. Before beginning to work in the mold-contaminated areas, contain the moldy work area (and thus contain the toxic mold spores that will be released into the air by opening up mold-infested walls and ceilings) by using wall-to-wall, floor-to-ceiling plastic sheeting as containment walls.

11. After the installation of air tight mold containment walls, dry the work area (especially if still wet from flooding or a now fixed water leak or roof leak) with one or more large dehumidifiers. Improper fan drying can spread mold spores to cross contaminate an entire building and its heating/cooling system.

12. Inside the mold containment area, use a large fan in the window to exhaust air directly outside on a continuous basis to expel airborne mold spores and remediation-caused dust—or better yet, use an industrial hepa filter to filter out mold, with a flexible hose directly venting the exhaust air flow to the outdoors.

13. While working inside the mold containment area, always wear effective personal protective gear such as protective biohazard suit. ($ 10 at safety stores) or painter’s coveralls and booties or a long sleeve shirt and pants; gloves; and a one piece, full face breathing respirator mask with an organic vapor cartridge filtration, available from local safety, hardware, and home improvement stores.

14. Spray or fog visible mold with one or two wet sprayings or foggings of either an EPA-registered mold fungicide or with an effective mold home remedy if the mold remediation funds are low. While spraying or fogging a fungicide no one else should be inside until the spray or fog has dried.

15. Do not use chlorine bleach to kill mold or disinfect moldy areas. Bleach is not an effective or lasting killer of toxic mold growth and mold spores on and inside porous, cellulose building materials such as wood timbers, drywall, plasterboard, particleboard, plywood, plywood substitutes, ceiling tiles, and carpeting/padding.

16. After the killing of all visible surface mold, the next step is to clean off as much surface mold growth as possible. Scrub and clean moldy surfaces and mold growth areas with either Borax laundry detergent (a natural mold cleaner) in warm water or TSP (trisodium phosphate) from a hardware or home improvement store

17. Except for wood support timbers and building materials to be saved, remove and safely discard all other mold-contaminated building materials in doubled up construction trash bags (double bagging) having a 6 mil thickness.

18. Remove all mold growth from the mold-infested wood surfaces. All wood beams, wall timbers, roof trusses, floor joists, plywood surfaces, and other lumber to be saved need to be totally cleaned of mold growth by using power tools such as a planer, grinder with wire brush attachment, and sander—or replace the moldy timbers.

19. Re-spray twice the cleaned out area with another wet spraying of an EPA-registered mold fungicide or an effective mold home remedy to kill any remaining, living toxic mold spores or mold growths.

20. Spray a protective fungicidal coating on all remediated-surfaces prior to rebuilding and closing in the mold-remediated area. The fungicidal coating helps to protect the wood and other cellulose-based building materials against future mold growth.

21. After the final drying of the fungicidal coat spraying, it would be helpful to spray all cleaned timbers and other wood surfaces with a clear, liquid, plastic coating (available from a local paint dealer or hardware store) to make a hard, impenetrable water barrier (upon drying) to protect the wood from future high humidity and water leaks.

22. After the toxic mold remediation is completed, mold test (clearance testing) all of the remediated surfaces plus the air of each room, attic, basement, crawl space, garage, and the outward air flow from each heating/cooling duct register to find out if those areas are now mold safe prior to rebuilding the cleaned out areas with new building materials.

23. Remove mold from all personal property, furnishings, furniture, and equipment that have been exposed to building mold by washing the items outdoors or in a plastic-sheet-built clean room with Borax laundry detergent (a natural mold cleaner) in warm water. In addition, spray a fungicide on all surfaces.

24. Close in the mold-remediated area with mold-free, new building materials which have been carefully inspected to be mold-growth-free, and which have been pre-treated by spraying with one to two wet coatings of both an EPA-registered mold fungicide and an EPA-registered fungicidal coating.

25. On-going cleaning, building maintenance, mold maintenance, and all-around building inspection on a regular basis (including air conditioning and heating equipment and ducts, plumbing, roof, siding, windows, and water supply and sewer lines) are required to help prevent the regrowth of toxic mold infestation problems. A mold-safe building is not a one-time effort.

Keep Your Bathroom Mildew Free and Your Family Healthy? Sashco Sealants Tips that Banish Menacing Mildew

Keep Your Bathroom Mildew Free and Your Family Healthy – Sashco Sealants Provides Quick Tips that Banish Menacing Mildew

Brighton, CO (Vocus) March 26, 2008

The term mildew often refers to the more than 100,000 different species of mold or fungus that exist. According to Sashco Sealants , manufacturer of MildewFree Sealant* (, mildew can be found living on a host of different surfaces and particularly thrives on surfaces like shower walls, tubs, bathroom sinks, bathroom windowsills and other areas where moisture and temperature levels are high. Sashco explains that, “Mildew can be transported by air, water, even insects and animals and can be nearly any color – black, orange, green, or white. Mildew can typically be identified by its thin, layered appearance than can quickly coat entire surfaces.”


Mildew is not only unsightly and can produce an unpleasant musty odor, but can also pose health risks if not eliminated. Although not necessarily always toxic or poisonous, molds and mildews are virtually inevitable in warm, moist environments like bathrooms. According to a quote by, “EPA estimates indicate that 50 to 100 common indoor mold types have the potential for creating health problems.” If members of your family suffer from respiratory infections, asthma, or bronchitis, paying close attention to mildew control is particularly important as exposure to mildew may, in extreme cases, be the principal cause or at least contribute to making symptoms more severe.


Several factors can be attributed to bathrooms susceptibly to mildew growth. They are typically relativity small in size, and regularly generate humidity and temperature ranges of 70 – 90 degrees which provide an environment where mildew flourishes. Bathrooms can create a breeding ground for potentially bothersome and definitely unsightly mildew growth. Once mildew growth occurs, it can spread quickly on bathroom walls ceilings, shower tiles, and grout.


Don’t despair! With regular maintenance and use of products specially formulated for mildew control, maintaining a mildew free home can be simple. Sashco recommends following these easy steps:


1.)    Use a mildew resistant sealant on tubs, showers, and sinks like MildewFree

Sealant* that is guaranteed to prevent mildew growth on the sealant for seven years or Sashco will not only replace the product, but also provide a contractor for re-installation.

2.)    Keep things dry. Wipe shower walls after taking a shower, or dry any excessive moisture from bathroom walls and windows.

3.)    Increase air circulation by opening doors and windows, running a fan, or installing an exhaust fan if necessary.

4.)    Place a box or two of baking soda in damp areas such as under sinks.

5.)    Clean susceptible areas regularly. Surfaces surrounding sinks, shower tiles, tubs, virtually any bathroom surface are highly susceptible to mildew growth and should be scrubbed regularly.

6.)    For deeper cleaning and prevention of mildew, sanitize the area with a household bleach mixture (1:9 bleach to water) to kill any existing mildew. Work the mixture into the joint and scrub well using a scrub brush.

7.)    If excessive mildew growth is already present on tub and tile surfaces, remove old caulking, thoroughly clean with bleach mixture and reapply new, mildew resistant caulking like MildewFree Sealant*.


*Cured sealant is mildew resistant.

Mold & Mildew Removal

It is very important to get rid of any mold or mildew that is in your home or work space. The sooner you can identify it the less damage will have been done. The first warning sign is often a very musty smell. Chances are the mold & mildew are growing in places where you can’t visually see them so make sure you start looking around. You may have more than one source of it as well so don’t stop your search when you come across one problem area.

In order to resolve the problem you are going to have to determine what the cause of the mold & mildew is. In many instances it is the result of a water leak. If you can’t find one then you should call in a professional to look as well. In areas where the climate is very humid it could be enough to trigger the growth of mold & mildew. In such cases you will need to install a dehumidifier in the area to reduce the amount of moisture that will be accumulating.

Anything that you can remove with mold & mildew on it should be taken outside. This includes curtains, rugs, and decorative items. The sunlight is very powerful and it will kill the spores in such items. You may have to use various types of cleaners to get rid of stains from the mold and mildew as well. Other items such as the walls and the carpet will be harder to get rid of the mold & mildew from as they can’t be easily removed from the location.

Since it can be very dangerous to your health to breath in the mold & mildew, you should be cautious when removing it. Wear gloves and a respirator as well as plastic over your clothing. You can get the big sheets of it for painting and then cut holes in it for your hands and head to fit through.

For big jobs of mold & mildew you should call in a professional to do the job. This is gong to be more expensive but you can be sure they will take care of the problem. If the mold & mildew was the result of damage from a water leak or something similar your home owner’s insurance may cover the cost of the clean up and removal. You will need to contact your agent to find out the specifics under your own policy.

Mold & Mildew Smell

One of the most common indicators that you may have mold & mildew lurking at home or in your office is the smell. It is very musty and you likely won’t be able to ignore it. If you do the problem will continue to develop and it will be even harder to take care of.

Since the presence of mold & mildew can also make people sick it is very important to find out what is going on. This way you can come up with a very effective solution to remove it.

The smell of mold & mildew may linger on longer than you like. In many instances you may have to do a second thorough cleaning a week or so later. If the mold & mildew has gotten too bad you will also have to consider replacing part of the wall or sections of carpeting. Do what you can to salvage the original items first but if it can’t be done you will have no choice.

You can definitely use various types of filters and fans to reduce the smell from mold & mildew but it isn’t recommended. Many people think if they can’t smell it they don’t have to deal with it. Yet the spores from the mold and the mildew are going to continue spreading like a wildfire. It can result in too much damage for you to just clean up from. You may end up spending thousands of dollars to get your walls and carpeting redone.

Only after you have removed all of the mold & mildew spores from the area should you consider using fans and ionizers. They can be effective to help get rid of the remaining smell that can linger for a very long time. If you have windows in the area open them to bring in fresh air from outdoors as well. You also want to open curtains so that the natural sunlight can come in. This will help kill off any remaining mold & mildew spores you may have accidentally overlooked.

While the smell of mold & mildew isn’t anything pleasant it at least lets you know you may have a problem to deal with. Pay attention to any new smells like that so you can take care of problems before they turn into something huge.

Mold & Mildew Killer

Getting rid of mold and mildew is quite a chore but it can be accomplished. Many of the chemicals to get the job done though can be harsh. You will be wise to make sure you have plenty of ventilation coming into the area. At the same time you should consider wearing a respirator. This way you won’t breathe in the harmful chemicals used to kill them or the spores from the mold & mildew. One new product called “BarrierTech” seems promising. It kills mold but does not remove the residue, but if you clean with bleach and then spray

the area with “Barriertech”, it will stay free of mold and mildew for at least 3 months and it’s totally safe for the environment, people and animals.

Bleach and hot water are the most commonly used elements for killing mold & mildew. You will want to dilute it with three parts water to each one part of bleach. Don’t attempt to use just plain bleach or you will be overwhelmed by the stench of it. A good mix also ensures that you can wash the walls and floors completely and not miss any areas.

There are some specific products on the market that are also to kill mold & mildew. You can get them at most hardware stores or online. You do want to carefully read the information on how to use them. Some are in a spray bottle and you just use them as they are. Others are in a concentrated form so you have to mix them with water. A mold & milder killer is only going to be effective if you use it as directed.

Once you have complete removed the mold & mildew, you may have stains on your walls to cover up. There are some brands of paint that have mold & mildew killer in them as well. If you live in an area where the climate is very humid this could be a very good investment for you. It will help prevent mold & mildew from becoming a problem for you again.

Look for a quality mold & mildew killer that includes both a fungicide and is a disinfectant. That way you will be killing both the fungus that is growing and the germs associated with them. There are plenty of quality products out there that you can use to effectively kill mold & mildew. If you don’t feel confident doing the job on your own you can hire a professional. They will have quality products as well that they use to get the job done effectively.
