If you’re a homeowner in New Jersey — especially in Bergen County, Passaic County, or Essex County — you may be wondering:
New Jersey’s climate — heavy snow, Nor’easters, coastal moisture, and aggressive freeze-thaw cycles — makes siding damage more common than many homeowners realize. What looks fine on the surface can hide serious structural issues underneath.
