FOUNDATION CRACKS ARE BAD
is not uncommon to find cracks in the foundation. This goes
for new houses as well as old ones. While there is a great
deal of engineering that goes into “reading” these cracks,
there is one rule that you should never forget. “Horizontal
cracks are a problem”. Of course not all vertical cracks
are acceptable, but they are generally not as serious as
a horizontal crack.
cracks in a new house: Most new foundations will develop
small vertical cracks. These cracks are a result of the concrete
shrinking as it cures. These cracks are about 1 /8
inch wide or less. They don’t affect the structure. The only
concern is leakage. If you see small cracks in a new foundation,
don’t panic. In fact, in a new home, some builders will pre-crack
the foundation and fill the crack with flexible material.
Few things are more misunderstood than plaster cracks on the inside of the house.
The following crack types are not generally related to structural
• a small crack (less than 1 /4 inch) that follows the corner
of the room where two walls meet
• small cracks that extend up from the upper corner of a door opening
following cracks may be related to structural movement –
• large cracks (larger than 1 /4 inch in width)
• cracks that run diagonally across the wall
• cracks on the interior finish that are in the same vicinity as cracks on the
exterior of the house.
