Just in time for Halloween.....
I have what sounds like a slow dripping (or ticking perhaps - it sounds
more like a drip to me) in one of the walls in our home. The noise seems to
coincide with the arrival of colder weather.
The sound was evident through the winter months and then went away for the
warmer months. It's now back. It does seem to be related to the outside
temperature but not to whether or not we are running our furnace. We live
in Ohio and the weather has been cool (40s occasionally at night) but we
haven't been near freezing or anything.
We moved into the house last January, the house is 10 years old and is a two
story with basement. Standard wood frame construction, forced air gas heat,
about 3200 square feet.
The noise is in the wall separating our family room from our garage. I am
aware of no plumbing in the wall. There is a cold air return near the base
of the wall in one area.
The garage is on a slab and the family room sits above a basement crawl
I first noticed the noise a few weeks after we moved in last winter. I
assume the noise was water dripping from the overhead Master Bath (not
directly overhead but I figured water was finding its way down the wall). I
checked for water damage or the presence of moisture in the cold air return,
basement crawlspace, garage, etc. We had the carpet in the family room
replaced (worn) and didn't notice any signs of moisture.
I've not torn into the wall and I've not hired anyone to specifically check
out the sound. I have had a roofer, plumber and HVAC technician listen to
the sound and give me their theories.
The roofer advised that it was unlikely (because of location) to be coming
from the roof. The plumber advised that it could be a leak but that there
should be evidence of moisture somewhere.
The HVAC tech advised that the temperature imbalance between the warm air on
the inside of the wall (family room) and outside wall (unheated garage)
might be causing condensation to form in the wall.
The house was vacant when we moved in. Original owners had taken a company
relocation so I can't ask anyone re: if the noise was something they lived
Any suggestions would be appreciated - thanks !
