Right now, I currently run a http://www.homedepot.com/p/AcuRite-D...d-Temperature-
In my house to measure the humidity levels in my house. I don't know the accuracy level of
such a device.
I have only taken measurements in my basement over the past week.
My above the ground garage (which an addition/family room sits on top of the garage) sits @ about
82% humidity. I can see paint chipping off of the ceiling of the garage. When I take a
dehumidifier, the dehumidifier definitely takes the humidity down to 45% and it doesn't take very
long for the humidity to drop down to 45% (at least in my opinion - like a couple of hours or
less). The garage has no block windows just an old garage door that has a small opening @ the
bottom right corner (nothing major in my opinion). The floor is cement and the walls are made of
big concrete a couple of minor openings in the areas where mortor would go (maybe 2 inches long).
There might be about 3 or 4 of those. Nonetheless there are about 3 or 4 of those. Would it
behoove us to look into a newer garage door?
Adjacent to the garage is a "I don't know what this room is" room. The room has a raised wood
subfloor and I have NO clue as to what is under there. I do know that there is an exposed plumbing
stack that goes down the wall (closest to the garage) and runs down under the raised wood sub
floor. The room also has a very very very old thin carpet on it that I want to get off of the wood
subfloor. Right now, this room is just housing junk as we just moved in a month ago. The humidity
is high in this room as well. I haven't left my humidity device in the room yet to track the
humidity. This room has a block window (prb 3x5) and a fire place which I don't know much about
and haven't used and won't use until I get that inspected.
This "I don't know what this room is room is" room is adjacent (opposite f the garage) to an open
finished basement which has drywall, carpet, tile, built-in entertainment center. I kept the
humidity device in this room for several days and the humidity level hangs around the upper 50's
to the low 60's. This room has 3 block windows (one is prb 3x5 and the other 2 are prb 2x2). One
of the 2x2 windows has a screen option in the middle where I could open a small portion of the
window. This room also leads you into a HVAV/laundry room and a small/narrow storage closet. The
laundry/hvac room has a 2x2 block window w/a vent in the middle.
There is a single door that will let you into each of the above adjacent rooms.
I have had the humidity device in the first floor living room and the humidity hung around the mid
50's. I haven't even brought this to the 2nd floor. I think I might lose it if I see those numbers.
We do have central air through out the house and this house was built in 1938 and we get a nice
air flow from the vents on the second floor. A lot better than I had ever expected. I have also
not even touched the 3rd floor/attic yet. A full bathroom on the 2nd floor have a fan that we use
The house is made of concrete block/brick and only the addition has a vinyl on it. The front of
the house has a tree and shrubbery. The side of the house has shrubbery next to it and that
surface is mostly clay. maybe the grade needs to be re-visited on that side. While I would admit,
MAYBE some of the drainage might need to be revisited, all of the drainage is draining away from
the house and drains might want to be tied in underground and go to an underground pool that would
collect the water.
I also see some step cracks in the mortar about the width of a hairline, could that be an air leak
and could that be a cause?
The windows on the house are relatively new 4-5 yrs.
I am at some losses and I just can't afford to Pi$$ money away. I am just tring to find the rood
cause(s). Again, there is no visible water coming into my house that I can see. Also, during this
whole process I have basically kept my thermostat/air on 70 deg. Can the high humidity in the
basement effect rest of the house? Although it seems as the whole house is humid and I don't know
where it is starting from. Maybe a vapor barrier for the room w/the wood subfloor? Maybe regrading
the perimeter of the house? Internal perimeter drainage system?
THANKS IN ADVANCE!
