Frequently asked questions
Are all cracks foundation problems?
No. Hairline cracks <1/8" are usually cosmetic. Wider cracks, diagonal cracks, or growing cracks need professional assessment.
Does insurance cover foundation repair?
Usually no — most policies exclude settling and earth movement. Coverage may apply if caused by a covered event like a burst pipe.
