As a home owner it's important to consider steps
to take toward
moisture prevention. For a prospective buyer, it's important
that you know if the grade or design issues with the home you are
looking at could one day lead to problems with moisture related
issues. Water and moisture are the biggest enemies to your home.
As a home inspector for the Knoxville, TN area,
one of my biggest concerns is looking for areas of the home that are
either damaged by water and moisture now or that could be in the
future. A poor grade that directs water into the house could cause
deterioration to foundation walls, basement flooding, mold or
rotting of wood in the crawl space. Gutters that are filled up with
leaves or are bent, and downspouts that don't properly direct water
away from the home are also a problem.
It only takes about a 20 percent moisture level
in wood for it to begin to deteriorate. At a 27 percent moisture,
level mold can grow readily.
Moisture doesn't have to be only caused by rain,
either. Plumbing leaks under the sink or under the floor can cause a
lot of problems as well.
Here are some defects related to moisture
problems I've found in recent inspections.
Relatively small cracks on top of a porch were
the apparent cause of water damage to the ceiling of a
basement garage area below the porch. Notice in the picture below
the rust and the bending in and warping of the metal ceiling caused
by rain infiltration.
In this photo, there was rotting wood found along
a chimney damaged by rain water. This defect would not have been
found by just a quick peak into the attic. It was located on the
opposite side of the chimney from the attic entrance.
Here we see venting into the attic. It's
important that bathrooms and dryers never vent into the attic. This
condition can create excess moisture in the attic that leads to
mold, and wood deterioration. These vents should always vent to the
Here we have tree limbs growing over the sides of
a roof contributing to clogged rain gutters and leaves standing on
the roof which can hold moisture on the roof and cause damage to the
roofing system over time.
