Blower Door Testing
 | |  | |  |
The Blower Door Testing is crucial when
trying to find where air leakage points occur.
We can determine how leaky the home is
overall and know how it compares to an air
tight home, leaky home or average home. If
a home is too tight with no ventilation, we will
know when the test is done and can
prescribe proper ventilation strategies to
prevent Mold, excess moisture and lowered
indoor air quality.
The Blower Door depressurizes the house to
Negative 50 Pascals which all homes are
measured. The Cubic Feet Per Minute flow
is measured across the fan to determine air
flow of the home after the Cubic Footage of
the home is calculated.
After the home is considered "leaky" we then
travel around the entire home and find
construction gaps, cracks, voids in
insulation, failed caulking areas,
innadequately sealed fireplaces etc... Every
Home is different and will show more or less
what can be done to reduce major leakage to
reduce Heating and Cooling losses. Air
leaks can also cause moisture condensation
areas leading to saturated wood, insulation
and Mold.
We then report on those air leaks with digital
photographs and describe in detail what air
sealing products to use to seal those areas.
