Mold Inspection Process. A mold
inspection is a modified home inspection of the house focused on
moisture control, plumbing leaks, floods, and storm water
drainage. Before starting, there is a client interview and
tour of the property.
Information gathered is
critical to understanding how the house may be performing.
Part of the process is determining how occupants make use of the
moisture control features of the house. If the house is under
contract, the home inspection report is
Outside Inspection. After the tour and
interview, a mold inspection begins with a full review of roofing, attic
ventilation, siding, utility penetrations, windows, doors, foundation,
crawlspace, gutters, and grade drainage. A check is made to
see if all components are installed and sealed
While outside, the size of the air
conditioning system is noted and compared to the heated square feet of
the building. For an average house, there should be 400-700
sqft per ton of cooling. Energy efficient houses my have
around 1000 sqft per ton.
Inspection. Once inside, the moisture control features of
the house are observed and may be operated. Key features
include ventilation, temperature control (with the heating and cooling
system), and humidity control.
Moisture vapor levels
are measured and compared to expectations, given the season, time of
day, occupant use of moisture control features, and building
construction. Relative humidity should be less than 50%, where
35-40% is ideal.
Components of the air conditioning
system are checked for a reasonable match. If warranted, a
comparison of the supply & return ductwork is checked against to
the capacity of the equipment it is attached to.
Stopping the Water.

Beware of Mold
Remediators Doing Mold Assessments! A Certified Mold
Inspector should do independent mold inspection and testing.
Home inspectors trained in home performance issues are better qualified
to the mold inspection because they have to know how and why every
system in the house works together. Understand that most home
inspectors are not trained in home performance. Their
contracts usually specifically exclude it.
remodelers and builders are not building scientists either, so they end
up doing what the they know and ignore what they do not
understand. Finding a mold remediation company who understand
the moisture control principles of building science are rare, but there
Mold testing should also be done by a
disinterested, independent third party. Initial tests should
be taken and interpreted by an independent mold inspector to avoid
scams. It's okay if a mold remediator wants to take mold samples
themselves to determine their own work performance before clearance
testing. Just be aware of the "fox guarding the hen
