Just four words neatly summarize what has to be done in effective and safe
Canadian
mould removal,
mould remediation, mould mitigation, and mould abatement:
CONTAIN, KILL, REMOVE,
and PROTECT.
(1) CONTAIN
the mould from spreading into uncontaminated areas;
(2) KILL
the mould;
(3) REMOVE
the dead mould; and
(4) PROTECT
the cleaned out area against future mould infestations.
Whether you plan on doing your own
Canadian
mould removal
and remediation, or hiring a
Certified Mould Contractor or
Certified Mould Remediator, follow these twenty-five steps
to completely and safely remove mould problems, contamination, and
infestation from your home, condominium, rental apartments, office,
warehouse, retail store or other real estate building in Canada. Where relevant,
mould testing and mould remediation suggestions from the U.S. Environmental
Protection Agency are included below.
The mould removal and remediation techniques explained below are useful for
removing and remediating mould from wood and other cellulose-based building
materials such as OSB board, drywall, plaster, plywood, and ceiling tile,
as well as mould growing on concrete and masonry surfaces such as bricks,
blocks, and poured concrete walls and floors. To remove mould from
furniture, appliances, clothing, and other personal property, please
follow the detailed mould decontamination instructions and procedures for
each different type of personal property, as explained in the mould
self-help book
Do-It-BEST-Yourself Mold Prevention, Inspection, Testing, and Remediation.

prosecuting or defending a mold legal claim, read
Mold Legal Guide [ebook]. Each ebook is only $15.00
each, or buy all five for only $49.total in the mold library combination
explained at Mold Mart.
2. Locate and fix all sources of
mould-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%].
Follow
the dozens of water-intrusion prevention and remediation suggestions
contained in the in depth ebook
Do-It-BEST-Yourself Mold Prevention, Inspection, Testing, and Remediation.
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 mould test kits [available at large home
improvement and hardware stores] or a
mold inspection by a
Certified Mould Inspector [CMI], and by cutting small core dry wall
samples. Remove and look in the middle and back of each core for visible
mould growth. You can also cut off thin veneer
moldy slices from each core sampling, and then insert each veneer slice
into a do it yourself mold test kit to watch for mould growth over a 7 day
time period. More valuable to you in mould insights, would be to put each
sample into a separate zip lock bag properly labeled with property address,
precise testing location at that address, date of testing, name of tester
[you probably], and your full contact info, and then to mail your
collected samples to the mould lab you desire to use.
For low-cost mould testing, use
inexpensive Scotch®Tape to do
lift tape mold sampling and/or do
bulk physical sampling [collect physical pieces of moldy building
materials or other items], and then send the tape samples or bulk samples
to a mould lab of your choice for mold species identification.
4. Find and locate all toxic mould
infestations (visible and hidden) in the entire home or building by
thorough, all-around
mould inspection and
mould testing (with mould laboratory analysis and mould species
identification of collected mould samples).
"You may
suspect hidden mold if a building smells moldy, but you cannot see the
source, or if you know there has been water damage and residents are
reporting health problems. Mold may be hidden in places such as the back
side of dry wall, wallpaper, or paneling, the top side of ceiling tiles,
the underside of carpets and pads, etc. Other possible locations of hidden
mold include areas inside walls around pipes (with leaking or condensing
pipes), the surface of walls behind furniture (where condensation forms),
inside ductwork, and in roof materials above ceiling tiles (due to roof
leaks or insufficient insulation)," warns the U.S. Environmental
Protection Agency.
° For all
building locations wherein you see visible mould, use the clear Scotch
tape
lift sampling method, or scrape visible mold particles into a mould
test kit [available at large home improvement and hardware stores].
° Conduct an outdoor
mould control test by using a do-it-yourself mould test kit outside your home or building with the test kit being at
least five feet out from any roof or porch overhang. You need this outdoor
control test for comparison of results from your indoor mould testing.
° Use a fiber
optics inspection device, a hidden moisture meter, and internal wall and
ceiling cavity mold testing to search for hidden mould growth.
5. Test the outward airflow from
each heating/cooling duct register for elevated levels of airborne mould
spores. If there is a serious toxic mould infestation anywhere in a
building, airborne mould spores from such mould locations will usually enter
and contaminate the heating/cooling equipment and ducts, as well as the
rest of the building. Use do it yourself mould test kits to collect possible mould spores in the outward air flow
from each register with the system running on fan ventilation.
6. Replace mould-infested heating/cooling equipment and ducts if the owner
can afford to do so.
Otherwise, do repeated mould spraying with a
mould fogging
machine and a
mould home remedy recipe into the return air duct while the system is
running on fan ventilation to deliver the fungicide to internal surfaces.
Do mould fogging for at least one half hour to hour into the return air
duct of the central heating/cooling system.
Air
conditioning-heating equipment and duct mould problems.
When humid air passes
over chilled cooling coils, water condenses and drips through the coils
into a collection pan, from which it continuously drains. Problems with
these systems may occur when this water collects and becomes stagnant
either on the coils or in the drip pan. When standing water is present, a
biofilm will develop. This biofilm is composed of bacteria and fungi that
are embedded in a slimy matrix. Other organisms such as amoebae and algae
may also occupy this comfortable growth site, feeding off the accumulated
organic material. Learn how to deal with this important problem at
Cooling Coil. In addition, it is common for the condensation line from
the cooling equipment to become clogged, backing up water into the air
conditioning unit and then, from there, into the house or building.
If there
is a serious mould problem anywhere in a home or other building, airborne
mould spores from those points of mould contamination will enter into the
heating/cooling ducts and/or equipment to mould contaminate both, and thus
the entire building. Of course, the opposite is also true: if there is
mould infestation growing inside the heating/cooling ducts and/or
equipment, the heating/cooling system will efficiently spread airborne
mould spores through out the entire home or building through air
distribution of the running system. In any home or building with mould
infestation, you need to mould test the outward air flow from each
heating/cooling duct register for the possible presence of elevated levels
of airborne mould spores in comparison with your outdoor mould control test.
Use a
Certified Mould Inspector or do-it-yourself mould
test kits, the use of which is explained at
Mould Inspection.
When
doing mould remediation of a house or building, the heating/cooling mould
problems should be fixed first, and then you can seal tightly with plastic
sheeting all inward and outward duct registers. Don't run the system until
the rest of the home has been effectively mould remediated and the building
has passed mould clearance tests done by an independent
Certified Mould Inspector not involved in the mould remediation work, or
by your use of do-it-yourself mould test kits available at a large
hardware, home improvement, or safety store..
If you
fog a mould home remedy
recipe into the return air duct while the system is running on
fan ventilation, you can get substantial amounts of mould remedy delivered throughout the system. While spraying or fogging a mold fungicide
[spraying step 1] and subsequently a
Mould Home Remedy Recipe [spraying/fogging step 2] inside the
heating/cooling ducts and equipment, no one [except the protected
applicator] should be in the home or building during the spraying or
fogging application. The person doing the spraying or
fogging application needs to wear proper personal protective gear, as
explained at point 13 below.
7.
If any residents or workers are experiencing any possible toxic
mould health
symptoms, or if there is a strong smell of mould, or if there
are visible signs of major
mould growth
anywhere in the building, or if the building tests positive for elevated
levels of airborne mould spores, the occupants should move temporarily to a
mold-safe place until after successful mould remediation and clearance
testing.
Hot Tips:
Do you want or need quick and immediate mould relief? The first
immediate action you can take is to remove almost all of the airborne mold
spores 24 hours per day from the air you breathe in your moldy home,
apartment, or workplace by running one or more of electronic air cleaners
(Friedrich being the best brand in effectiveness according to
Consumer Reports)
in different areas of your house, rented house/apartment, or place of
employment. Your second immediate action is to use a hand-pumped garden
type of sprayer to spray two coatings of a low-cost home-remedy
fungicide in all rooms, attic, basement, crawl space, garage, and the
heating/cooling equipment and ducts [through the return air duct while you
are spraying directly into the return air duct] of your home, condominium,
apartment, office, or other building. You can also place small to
large fans in key areas of rooms/areas being mould-sprayed to help the mould
fog to reach all areas of a room or area.
Let each fungicidal spraying dry for about one to two hours while the
fungicide is killing the mold. Then fan dry the area quickly to remove
excess moisture from the spraying procedures. Then fog with two layers of
homemade
antimicrobial coating
to help protect the areas against future mold growth. After each spraying,
let the fog set for about one to two hours, then dry the area quickly with
fans. The person doing the fungicidal spraying or
fogging application needs to wear proper personal protective gear, as
explained at point 13 below.
8.
Occupants moving out should not take any clothing, personal possessions,
furnishings, furniture, or equipment until after such items have been
effectively mould decontaminated outdoors [or in a clean room built from
plastic sheeting] to avoid mould cross contamination of the temporary
living or working quarters.
9. Do not paint over mould problems.
Mould loves to eat paint as a snack food. Don’t expect to kill mould
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. Do
not rely on
Kilz to kill mould or anything---it does not kill mould, and the
product is NOT an EPA-registered fungicide. Kilz is a good product to hide
or camouflage defects like water damage stains prior to painting over
problem areas AFTER mold remediation has been completed.
10. Before beginning to work in
the mould-afflicted areas, contain the mouldy work area (and thus contain
the toxic mould spores that will be released into the air by opening up
mould-contaminated areas) by using wall-to-wall, floor-to-ceiling plastic
sheeting as containment walls. How to make effective mold containment
walls, including a mold-secure entry way into the mould containment area,
is explained in detail in the ebook
Do-It-Best-Yourself Mold Prevention, Inspection, Testing, and Remediation.
Use 6 mill thick, clear plastic sheeting that you can buy at a hardware
store or home improvement center.
11. After the installation of air
tight mould 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 or an industrial size dehumidifier. Improper fan
drying can spread mould spores to cross contaminate an entire building and
its heating/cooling system.
12. Inside the mould containment
area, use a large fan in the window to exhaust air directly outside on a
continuous basis to expel airborne mould 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. You
need to exhaust more air to the outside than is entering the containment
area to create negative air pressure. (You know you have negative air
pressure when the plastic containment sheets are being sucked inward
toward the work area rather than bulging outward away from the work
area.).
13. While working inside the mold
containment area, always wear effective 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 using an organic vapor cartridge
filtration, available from local safety, hardware, and home improvement
stores. You also need such personal
protective gear when you spray
Mold Home Remedy Recipes], followed up with the EPA-registered
fungicidal coating or with a low-cost, homemade
antimicrobial coating Here are more details on
advisable personal protective gear---
° Tyvek protective biohazard suit.
[available at safety stores] or painter's coveralls and booties, or long
sleeve shirt and pants.
° Gloves: either disposable latex
or good work gloves. "Long gloves that extend to the middle of the
forearm are recommended. When working with water and a mild detergent,
ordinary household rubber gloves may be used. If you are using a
disinfectant, a biocide such as chlorine bleach, or a strong cleaning
solution, you should select gloves made from natural rubber, neoprene,
nitrile, polyurethane, or PVC. Avoid touching mold or moldy items with
your bare hands," recommends the U.S. Environmental Protection Agency.
° Avoid breathing
in airborne mould spores. Wear a 3M brand
one piece, full face breathing
respirator mask using an organic vapor cartridge filtration, available
from your local safety store, Home Depot, Lowe’s and other home centers
and hardware stores. Alternatively (but less comfortable in your ease of
breathing) you can use hole-free Chem-Splash eye goggles ($4) along with a
separate breathing mask with cartridge filters ($30) from the same stores.
Alternatively, "In order to limit your exposure to airborne mold,
you may want to wear an N-95 respirator, available at many hardware stores
and from companies that advertise on the Internet. (They cost about $12 to
$25.) Some N-95 respirators resemble a paper dust mask with a nozzle on
the front, others are made primarily of plastic or rubber and have
removable cartridges that trap most of the mold spores from entering. In
order to be effective, the respirator or mask must fit properly, so
carefully follow the instructions supplied with the respirator. Please
note that the Occupational Safety and Health Administration (OSHA)
requires that respirators fit properly (fit testing) when used in an
occupational setting; consult OSHA for more information (800-321-OSHA or
osha.gov," advises the U.S.
Environmental Protection Agency.
° Wear goggles.
Wear eye goggles with no holes [such as Chem-Splish] if you are not
wearing the 3M brand one piece, full face breathing respirator.
"Goggles that do not have ventilation holes are recommended. Avoid
getting mold or mold spores in your eyes," advises the U.S. Environmental
Protection Agency.
HOT TIP:
You can order a custom-fitted full face breathing mask by contacting your
local 3M branch. Custom-fitted full face masks do a better job of keeping
mould spores from entering inside the mask [and therefore into your body].
HOT TIP:
If you have a beard, shave it off prior to wearing a full face mask
breathing respirator to obtain a tighter fit to your face to help keep
mold stores from entering inside the mask and your body.
14. Kill surface mould
growth by with one or two wet sprayings or foggings of an effective
mold home remedy mold cleaner---read
Mold Home Remedy Recipes. While spraying a fungicide, no one
else should be inside until the spray or fog has dried. Use a hand-pumped
garden sprayer or a small electric sprayer. If doing mould fogging, fog
the Mould Home Remedy Recipe for at least one half hour in each room, and
one half hour to hour into the return air duct of the central
heating/cooling system while the heating/cooling system is running on fan
ventilation. If possible, remove all furniture from each room to be fogged
to fog the empty room [without furniture blocking access of the fungicide
to wall and floor areas]. Then repeat the process but on the second effort
with the furniture put back in the room to do mould killing on the
furniture itself.
IMPORTANT OZONE WARNING:
Do not use an Ozone Air
Purifier/Ozone Generator to kill mould. Ozone is ineffective in killing
mould. Ozone can only kill what it comes into
contact with. Ozone cannot get at, and thus cannot kill, mould growing
INSIDE drywall, wall, carpeting, upholstered furniture, wall cavities,
ceiling cavities, and floor cavities. Besides being ineffective at killing
hidden mould [the worst type], a high ozone treatment can easily damage all
rubber and plastic parts it comes into contact with such as rubber and
plastic components of appliances, electronics of all types, exposed
electric lines and extension courts, and hvac controls. Ozone is also
unhealthy to humans according to the U.S. Environmental Protection
Agency, which specifically discourages the use of ozone for mould
remediation. For more information on the ineffectiveness of
Ozone and the Ozone Air Purifier to kill mould and other indoor
air contaminant, read the highly-informative U.S. Federal Appeals court
decision:
Federal Trade Commission and the Court of Appeals.
A recent medical health study has discovered that indoor ozone is
especially unhealthy for women.
15. Do not use chlorine bleach
[sodium hypochlorite] to kill mould or disinfect mouldy areas. Bleach is
not an effective or lasting killer of toxic mould growth and
mould spores on and inside porous, cellulose building materials such as
wood timbers, drywall, plasterboard,
particleboard, plywood, plywood substitutes,
ceiling
tiles, and carpeting/padding. Learn more about
why bleach doesn't work at
bleach and mold.
16. After the killing of all
visible surface mould, the next step is to remove and to clean off as much
surface mould growth, mould stains, and mould odors as possible. "Dead
mold may still cause allergic reactions in some people, so it is not
enough to simply kill the mold, it must also be removed," recommends the
U.S. Environmental Protection Agency. Persons cleaning mold
should be free of mold symptoms and allergies. Gloves should be worn
during cleaning. A good first step is to use a hepa vacuum cleaner to
remove loose [invisible to the eye] airborne mold spores and mold growths
deposited on all surfaces such as ceilings, walls, floors, and upholstered
furniture. Vacuum at least twice, going in a different movement direction
each time you do the vacuuming---e.g., horizontally the first time and
vertically the second time. Scrub and clean thoroughly and completely
all surfaces [including furniture and appliances] with Borax laundry
detergent, a natural mould cleaner, in warm water. The cleaned area should then be thoroughly dried.
Dispose of any sponges or rags used to clean mold.
If
you cannot clean off the mold growth and mold stains with a hard scrubbing
with Borax in water, then you probably need to replace the
building materials themselves with new ones---preventively-treated with
the EPA-registered fungicidal coating. "If you are unsure about how to
clean an item, or if the item is expensive or of sentimental value, you
may wish to consult a specialist. Specialists in furniture repair,
restoration, painting, art restoration and conservation, carpet and rug
cleaning, water damage, and fire or water restoration are commonly listed
in phone books. Be sure to ask for and check references. Look for
specialists who are affiliated with professional organizations,"
recommends the U.S. Environmental Protection Agency.
17. Except for wood support
timbers and building materials to be saved, remove and safely discard all
other mould-contaminated building materials (such as particle board,
drywall, plaster, plasterboard, ceiling tiles, paper-backed insulation,
mold-laden insulation, plywood, plywood substitutes, and
carpeting/padding) in doubled up construction trash bags (double bagging)
with a 6 mil thickness. "Absorbent or porous materials, such as ceiling
tiles and carpet, may have to be thrown away if they become moldy. Mold
can grow on or fill in the empty spaces and crevices of porous materials,
so the mold may be difficult or impossible to remove completely," advises
the U.S. Environmental Protection Agency.
18.
Remove all
mould growth from the mould-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 mould growth by using power tools
such as a planer, grinder with wire brush attachment, and sander---or
replace the mouldy timbers. Mould cannot eat polystyrene insulating
board such as Pinkboard or Blueboard, but mould can grow on organic dust
which lands on the insulating board. "The
only sure way to [kill mold] requires the physical elimination of mold
and moldy materials by thorough cleaning or removal of the affected
materials."---American Industrial Hygiene Association.
19. Re-spray twice the cleaned out
area with another wet spraying of an effective
mould home
remedy to kill any remaining, living toxic mould spores or mould
growths.
20. Spray a protective fungicidal
coating on all remediated-surfaces prior to rebuilding and closing in
the mould-remediated area. The fungicidal coating helps to protect the wood
and other cellulose-based building materials against future mould growth. After the second spraying of a
mould home remedy recipe
has dried, spray one or two wet coatings of a mould home remedy
fungicidal coating designed to protect wood against future wood
infestation problems..
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 well-stocked local paint dealer, hardware store, or home
improvement center] to make a hard, impenetrable water barrier [upon
drying] to protect the wood from future high humidity and water leaks.
22. After the toxic mould
remediation is completed, mould test (clearance testing) all of the
mould-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 mould safe prior to
rebuilding the cleaned out areas with new building materials. "Surface
sampling may be useful to determine if an area has been adequately cleaned
or remediated," advices the U.S.
Environmental Protection
Agency. There should be NO residual mould smell and no
mould or water stains anywhere.
23.
Remove
mould growth, mould stains, and mould odors
from all personal property, furnishings, furniture, and equipment
that have been exposed to mould infestation by washing and scrubbing
the items thoroughly and completely outdoors [or in a plastic-sheet-built
clean room] with Borax laundry detergent, a natural mold cleaner,
in warm water. Learn the recommended mould decontamination procedures for each type of
clothing, furniture, electronics equipment, and other personal property in
the ebook
Do-It-Best-Yourself Mold Prevention, Inspection, Testing, and Remediation.
24. Close in
the mould-remediated area with mould-free, new building materials that been
have carefully inspected to be mould-growth-free,
and which have been pre-treated by spraying with one to two wet coatings
of both a
mold home remedy recipe and an EPA-registered fungicidal
coating.
25.
On-going cleaning, building maintenance, mould maintenance, and all-around
building inspection on a regular basis (including air conditioning/heating
equipment and ducts, plumbing, roof, siding, windows, and water
supply/sewer lines) are required to help prevent the re-occurrence of
toxic mould infestation problems in your Canadian home or other building.
Creating a mould-safe building is not a
one-time effort.
