Get a dehumidifier. If your basement temps are 65 or below get a unit
that wont freeze till 45-50, All regular, or most units, freeze up near
65f. Sears has one unit that goes to 45f
Buy a digital humidistat or an analog unit designed to be calibrated
and calibrate it. Keep humidity at apx 50% and mold will die on its own.
But the trapped moisture in wood on the floor has to be fixed, best is
remove the wood .
I had mold issues and leaks and killed the mold by spraying walls and
floors with laundry bleach. I stopped the leaks and keep humidity under
65 and no mold has returned.
Bleach will stink bad for 1-4 days, if your wife is there and
pregnant, now is not the best time for this, perhps later when she can
leave for 2-5 days. I would wait on wood removal also to keep the mold
from going airborn, now it is sealed in.
Don`t Red Flag your self to the insurance co with a call.
Pros overcharge for mold issues. A flooring company or construction
company could do the removal of wood quick, you could spray and clean
it. If the floor doesn`t seap up water which you test by taping plastic
on it for a day and test with a 20$ HD Moisture meter, put down tile,
vinyl, or paint and leave bare. I have a 200$ Delmhorst moisture meter.
Your issue is real common, and is no need for panic, just figure the
right way to go about your upgrade. Without controlling humidity mold
will stay, and yours may actualy be ok, but 95% of basements here need
dehumififiers in spring- summer. Just plan out your job a step at a
Ive shopped for humidistats many times, I have 8-10 of them, many are
junk. 95% of the Analog units you see on displays at Ace, HD etc are
made by Taylor and 95% are uncalibrated and vary in store, on display,
5-15%. Digitals are usualy fairly accurate in the indoor range you
need to measure. Taylor makes one Analog unit a 3" round silver unit,
out of maybe 25 they make, that is designed for calibration, it comes
with a tool and instructions that state, "Calibrate every 6 months" so
the rest they make are really worthless, unless digital. There is no
reason to pay extra to over dehumidify or take no action due to a crappy
A flooring company might just be your best bet, they know what
basement floors require, how to test, and spot issues. They will direct
you best on what to do to have a floor that lasts. Humidity control, and
leaks are your issue, but simple to do over time.
Honestly a proper dehumidifier for your temp and sq ft, and a good
humidistat would be my first step today, get a digital unit at a store a
bunch are powered on and you can see " off %" units. Then get a few
bids-ideas from floor companies.
