Q.
We are thinking of buying a building which when we inspected had
considerable mould covering the ceilings in the basement (large black rings
of it). It appears the mould may have developed due to a defective water
fountain on the main floor as the floor around the fountain is damp and
rotten. Also the basement windows have been boarded up for some time as the
building has not been in use for about 5 years.
The smell in the basement
is overwhelming yet the main floor seems in good shape with no smell or
evidence of mould there. What do you think our chances are of getting rid of
this problem? And how do we go about it? Incidentally the basement is 90%
above ground.
A.
It is likely that the basement mould will have grow into the
insides of the floor and walls above, necessitating doing internal
ceiling/floor/wall inspection through 2 inch by 2 inch or smaller inspection
holes cut into those surfaces, as explained at
Mold Inspection
and in the mould remediation section at
Mold
Removal & Remediation. It is also likely that airborne mould spores form
the basement mould will have traveled in air currents to mould cross
contaminate the entire house and its heating/cooling system. Use do it
yourself mould test kits [available for delivery in Canada at
http://www.moldmart.net] to mould test the air of the basement, each room above, attic, and the
outward air flow from each heating/cooling duct register for the possible
presence of elevated levels of airborne mould spores, in comparison to an
outdoor mould control test.

Q.
I have a client who has light colored vinyl flooring in her basement
bathroom and there are dark spots under the vinyl flooring that look bluish
or blackish. The spots look like mould to me, they had this floor put down
around 5 years ago and they now want it replaced before it gets worse or
spreads.
I believe it's because the
cement floor is drawing moisture and being trapped and causing mould. Can I
take the vinyl floor up, kill the mould and then use a ceramic tile on the
cement floor? I have heard there is a rubber membrane available you can put
on the floor then your mesh then scratch coat, does that sound right?
A.
Your diagnosis and treatment plan are very good. What is your
profession? You should expand your expertise to becoming trained and
certified as a Certified Mould Inspector and Remediator. There is a big
demand in Canada for such services, but very few trained inspectors and
remediators. Visit our training website:
http://www.ecology-college.com. As an alternative to the rubber membrane
and probably more effective on a long-term basis is to remove the vinyl,
kill the mould with a strong fungicide, remove the mould growth, and then
apply about a one inch thick new basement floor cement finish containing
adequate amounts of waterproofing compound---or do both this approach and
your good idea of putting a rubber membrane on top of the new floor
waterproofed cement liner.

Q.
I rent a home in Toronto, Ontario and have
recently had many problems with leaking and flooding in the basement. The
landlord has denied any structural problems with his house and so I had an
inspector come to assess the property. Over 20 violations were cited but
unfortunately this inspector was not able to assess the mould problem
because that falls under another jurisdiction.
My question is about black
mould. I have seen what I believe to be this type of mould in the basement
and have just recently discovered that in all probability that the walls are
full of it although it is not all visible. I have a two yr. old daughter who
has also just been diagnosed with asthma and I am now worried for the safety
of my family.
My landlord has just had
the roof repaired and tells me when I express my concern about the mould
that "it will all go away without moisture, now". Unfortunately I have also
just renewed a lease and I want to know the exact danger that we are
potentially in. Thank you for your time and I would greatly appreciate
further information about this.
A.
The leaking and flooding problems in the
rental house are going to generate huge levels of indoor mould infestation,
both visible, and growing inside floors, walls, ceilings, and the
heating/cooling system. The health of your young daughter and your entire
family is at serious risk for major and permanent health damage unless you
move promptly to a mould safe place to live.
Unless you take steps like
the
Tenant Notice to Landlord About Mould,
and doing your own documentation of the mould problem with our do it yourself
mould test kits which we can ship to your Toronto home, it is likely that
your landlord, like most landlords, will do nothing as to safe and effective
mould inspection, testing, and remediation of your rental unit's mould
infestation problem. You would be wise to move to a mould-safe place as soon
as possible. Most mould lords will not spend money to protect tenants against
mould health threats. Learn about
landlord mould liability. If you are going to move out from your present
mould hell, or just move out temporarily during mould remediation, you should
carefully mould inspect and test your temporary or new living quarters prior
to renting or buying and moving to make sure you are not moving from one
mould hell to another. As for your personal property, you are wise to do mould
decontamination by washing all items outdoors by washing them thoroughly
with Borax laundry detergent, a natural mould cleaner, in warm water. Use one
pound of Borax per 1.5 gallons of water. Then spray all items with one or
two wet sprayings of your home-made mold killer recipes. To document your
apartment mould health threats, you can use our do it yourself mould test
kits, available from
http://www.moldmart.net. Learn the
mould remediation steps that your landlord needs to take AFTER you vacate
the apartment [mould remediation while you are in the apartment will make
your family even more ill].

Q.
The
complex I live in has a lot of black mould in the insulation in the
basement. We have started to notice that members of the complex are
getting sick. Most are dealing with bleeding noses, headaches and allergy
symptoms. Could this possibly be coming from the mould?
A.
Yes,
the health problems you list are possibly mould health symptoms---read the
list of the top 60 mould health symptoms at
http://www.moldinspector.com home page.
Basement mould can easily grow into the floors and walls
above. In addition, airborne mould spores from the basement mould can travel
in air currents to mould cross-contaminate the entire Canadian apartment
complex. Here are several helpful mould tips---To get rid of the mould
threat to your health and home investment, first, check your home or
building for water intrusion problems. Make sure your kitchen and bathroom
exhaust vents go directly to the outside, not into your attic or inside
walls.
Check your home carefully for attic, siding, plumbing water
leaks, construction defects, or maintenance degradation which permits
water to enter your home. Make sure that the roof is properly vented to
allow moisture to escape rather than collect in the attic. Check all areas
of your house year round [including basement, crawl space, each room, and
attic] for the possibility of high indoor humidity with a $30 hygrometer
from a large hardware store, Home Depot, or Lowe's. If the humidity
exceeds 50 to 60 percent, you have invited mould to be your permanent house
guest. Use a programmable dehumidifier to keep indoor moisture to a
mould-discouraging 30 to 40%.
Air conditioning systems should be checked to ensure that
they drain properly and do not retain moisture. Moisture, along with dust
particles that occur in the system, creates a breeding ground for mould
that can then be spread by the heating/cooling system through out the
house. Also use your sense of smell and a strong flashlight to thoroughly
inspect all areas of your home for visible mould growth.
Second, use a do-it-yourself mould inspection and mould air testing should be your
first steps to determine whether your home and workplace have a serious
mould infestation problem. You should visually check all areas of your home
with a flashlight and your sense of smell [e.g., duct registers, attic,
crawl space, basement, etc] in accordance with the physical mould
inspection tips provided at Mould Inspection. If there is even a hidden
mould problem inside walls, ceilings, attic, and the heating/cooling
system, usually detectable airborne mould spores will make it into the air.
If the indoor mould levels are elevated in comparison to
your outdoor mould control test, you know that you probably have a serious
mould problem which needs further investigation and possible mould
remediation. You can use mold test kits to mould test any visible mould
growths, the air of each room, basement, crawl space, attic, garage, the
outward air flow from each heating/cooling duct register, and inside the
passenger compartment of your vehicles [often mould cross contaminated if
your home or office is mould infested]. Watch the mould test kits for 7
days. If any of the test kits show a large number of mould colonies of one
more different types of mould [visually different to you], you can submit
the mould test kits into a mould laboratory for mould analysis
and mould species identification [only $49 per mould sample submitted]. If
mould test results indicate a problem, you may then want to then hire a
Certified Mould Inspector to use fiber optics to inspect inside walls,
ceilings, floors, and the heating/cooling ducts for evidence of physical
mould growth, and to do in depth mould investigation and inspection. Learn
the 25 steps recommended for
safe and effective mould remediation. Buy the best air cleaner to remove airborne mould spores from your home, apartment,
or office air to protect your family's or co-workers against breathing in
elevated levels of airborne mould spores.

Q.
Having
new home built and are scheduled to close July 25th. We have noticed in
the basement along one long interior wall is concrete but I refer to it as
interior as it is not the true outside concrete wall. It is the basement
concrete wall along the inside back of garage.) Since the foundation was
poured in January, it remains damp half way up the wall. It is now July.
We live in Pennsylvania.
We have had a lot of rain and noticed a couple of days ago that the
dampness in this area is even darker. We spoke with the project manager
this morning who indicated this condition has been noted and they believe
that since they have not graded a final time yet that water is getting
down into this area and causing the dampness on the wall. Their remedy
first is to power wash the basement floor and then put fans in the
basement to dry everything out and to grade the dirt.
When we spoke with him on the phone this seemed reasonable however when we
looked back at the house plan this is not an exterior concrete wall. Our
thought is why would the dampness be on the interior wall. Grading will
take place outside the exterior wall.
Should we be concerned? Could fixing the problem as he has stated be
sufficient, do we need to have the house tested for mould, or should we get
some type of document from the builder that says if the problem does not
clear up they will be responsible?
Thank you for your assistance.
A.
You
must get this water problem fixed to your satisfaction before buying the
home or you are going to have sufficient water intrusion to enable
big-time mould growth in your new home. The wet wall will drive up indoor
humidity levels, thus making mould be able to grow through out your home,
especially after continually re-circulating airborne mould spores through
your heating/cooling equipment and ducts. The wet wall can also ultimately
have mould growing on it as organic dust and dirt lands on the wet wall,
providing food for airborne mould spores to grow after landing on the wet
wall. You need to have the wall and water problem inspected by a qualified
professional such as a licensed physical engineer, basement foundation
contractor, and/or home inspector. You must discover for sure what is the
cause of the water problem and what is the solution that will work. If the
problem is simply the grade that the home builder says will take care of
the problem, delay the closing until a few weeks after the grading is
done. Better yet, ask your attorney to negotiate a holding of some of the
purchase funds of the house into an escrow account to cover future water
problems. Keeping water and high humidity out of your home is of the
utmost importance to your family's health and financial well-being.
>> July 9, 2003
Q.
I
received a letter from my home builder explaining that they found mould in
my new home, but that they took care of the problem. They also asked me to
sign a waiver agreeing to not bring any claims against them with regards
to the mould found prior to closing. Is it safer to build a new home,
refuse to sign, or sign?
A.
You
need to ask your legal question of an environmental attorney in your area
[Mould Lawyer]. You need to pay for your own mould
inspection and mould testing to know the truth about the existence, types,
and extent of mould infestation in your home and its heating/cooling
equipment and ducts. Your family's health is too important to ruin by
living in mould infestation. To find a Certified Mould Inspector, please

Q.
I
think there is a serious mould problem in the house we are renting. There
has been water / sewage leak under the house. I don't know how long this
has been happening but there was a substantial amount of sewage / water
building up under the house. As soon as the problem was discovered, we
notified the landlord and within a couple of days a plumber came to the
house and fixed the broken pipe. However, he did not clean up any of the
existing sewage / contaminated water. There is a very distinct musty /
damp odor in the house and just recently my infant son has become sick. I
am not sure if there is a connection or not but for my peace of mind, I
would like to find out how much it would cost for testing and when it
could be performed.
A.
You
should use our do it yourself mould test kits with our expert mould
laboratory analysis [Mould Mart] to mould test the area beneath your house,
every room of your house, the attic, and the air flow out of heating/air
conditioning ducts. What you are testing for is the possible presence of
elevated levels of airborne mould spores, a sure sign that you are living
in mould contamination. The sewage line breaks beneath your house will have
caused massive mould growth that may be eating its way into the floors and
walls above. Moreover, broken sewer pipes will cause severe biological
contamination of your home. Your best bet is to move as soon as possible
to a safe place to live. Most landlords will not spend any money for
effective mould inspection, testing, and remediation.

Q.
I
think I have found black mould in our basement shower. I don't want to
turn a claim into our insurance company because I fear it will cause our
insurance price to raise. Our basement has flooded a couple of times in
the past few years . I've been using bleach to take off the mould. Is this
sufficient? I've been reading some of the stories on your Q&A section and
we have also had to snake our drains once a year for the past several
years. We have many old trees around our house and my husband says the
roots are the problem but should I be concerned about mould there as well?
The shower is concrete slab and the bleach is slowly removing it . I'm
also removing mould from the basement ceiling and removing carpet that it
was under. Is this something I can continue on my own using bleach and
thoroughly cleaning or would it be best handled professionally?
A.
Bleach
is too weak to be an effective mould killer. Moreover, it is not
EPA-registered as a mould fungicide. If you want the maximum killing
power, use two wet sprayings of EPA-registered antimicrobial protective coating. Even more important to you is to
find the water source that enables mould to grow in your basement. You
cannot continue to have basement floods if you want to rid your home of
mould. Stopping water problems must be your number one mould remediation
step! You also need to remove all visible mould in accordance with the
precise steps recommended at
Mould Removal. You also need to
inspect and mould test the rooms above the basement, your attic, and your
heating and cooling equipment and ducts for the possible presence of
elevated levels of airborne mould spores, which, if present, would be a
sure sign of a serious mould infestation problem. With as much flooding and
mould growth as your house has experienced in the basement, your upstairs
is possibly mould-contaminated through cross-contamination by airborne mould
spores.

Q.
I am
possibly seeking a mould inspection in my home, particularly in the
crawlspace. Since I have turned on my AC this summer, I have noticed a
strong odor coming from the vents. (I have baseboard electric heat in the
winter and did not notice this smell this past winter.) Upon further
inspection (pulling off the cover to the crawlspace) I noticed the same
foul odor there. I suspect that my AC is drawing some of its air from the
crawlspace and I would like to know if I have a mould problem growing under
my 1975, 1400 square foot ranch style home. What type of inspection do you
do? What does it require on my part? I live in North Manchester, IN and
would be interested in finding out what you can do for me.
A.
Heating and cooling equipment and ducts can cross contaminate mould spores
and mould infestation from one area [such as your crawl space] to other
areas [such as your entire house!]. Your first step should be to mould test
the crawl space air, the air of the various rooms of your home, and the
air flow out of heating/cooling ducts. You can do this either with one of
our Certified Mould Inspectors in Indiana [Mould Professionals] or use our do it yourself mould test kits with our expert mould
laboratory analysis
Mould Mart. You
will need to find and stop the water source that enables mould to grow in
your crawl space. You will need to remove all mould growth in the crawl
space and treat the area with antimicrobial protective coating
[Mould Removal].

Q.
I have
a customer wanting to buy a condo and mould was discovered in the attic
from the bathroom fans venting into the attic. The insulation is black
with mould as well as the plywood sheathing on the roof. The seller thinks
that if he just redirects the vent to the outside this should be all that
is needed. Now, I think this is just the first step. Is it safe for the
insulation to stay where it is and the roof plywood to stay without any
clean up?
A.
The
insulation will have to be thrown out. The mould growing on the wood will
have to be completely removed by a power planer and a wire brush attached
to a grinder----or, better, replaced with new mould-free materials. The
area will need fungicidal treatment with an EPA registered antimicrobial
coating [available at
MoldMart]. All of the other required steps for safe and effective mould treatment explained at:
mould removal section
and mould types section.
In addition, the following areas of the home will need to be
professionally inspected and mould tested: INSIDE the ceilings beneath the
attic, INSIDE the walls beneath the attic, plus testing the room air of
all rooms and the air flow out of heating/air conditioning duct registers
for elevated levels of unhealthy mould spores.

Q.
I recently moved
out of an apartment building that I had lived in for approximately 3-4
years. It seems that after living there for 6 months or so, I started
developing sinus infections and upper respiratory infections which would
lead into bronchitis and pneumonia. I never thought that it was where I
lived. I have allergies and I unfortunately smoke, so I blamed myself. But
the past two years I have been having difficulty thinking, remembering,
and even speaking. I'm turning 31 years old at the end of this month and
don't believe it's from age. When I moved into this apartment, it was
remodeled and new carpeting was put down in the bedroom and the living
room. However, about a year later, the bedroom carpet started developing
black spots, I thought at the time mould. But it had absolutely no odor
when I smelled it. Once the black spots were in the light of the sun for
so long, they faded, almost bleaching circles EVERYWHERE. The bedroom was
the worse place for me to sleep. I just thought that the building was
built in 1960 and it probably was damp. And I've always had one allergy or
another, just not to dust and mould.
Well, about 1 1/2
years ago is when my memory started to go. I would black out, I couldn't
concentrate long enough to tie my shoes, so I went to a psychologist and a
psychiatrist, thinking I was psychotic over some instances. I was
diagnosed, but no medicine worked. So I was at a loss. My fear is my
health, however, I gave birth to my daughter at the end of February. She
was at the apartment with me for five weeks before we moved from there. I
had to get her out because I knew there was something wrong. I'm in fear
for her health. At the time that I moved, I was experiencing severe
headaches, a dusty fumy smell that I thought was a gas leak at one point.
I would sleep like I was drugged. I couldn't breathe well, and plus my
memory problems, and other things I just can't think of.
My questions are:
If this is from Stachy, now that I'm gone from there, will my memory still
get worse? or will it just stay as it is? Also, do you think my daughter
will have severe damage of any sort from living there for 5 weeks? And
what should I do now?
A.
There
is very little research on the lingering health effects of prior exposure
to mould infestation. You were very wise to move from that mould hell for
the well-being of you and your child. You and your child should be
examined by a pulmonary physician who can do diagnostic testing like lung
biopsy, lung x-ray, and mould antibody blood testing. You can check with an
ear-nose-throat specialist to test for mould growth inside your and your
child's nasal cavities and sinus cavities. You can check with a
neurologist as to possible brain damage. The brain problems you have
suffered are typical symptoms of deadly Stachybotrys mould which destroys
brain tissue.
