Hanover Park sits at the intersection of Cook and DuPage Counties, which means ZIP 60133 homeowners deal with a split of municipal rules and building codes depending on which side of the county line their property falls on. The area is made up largely of post-war and 1970s-era ranch homes, split-levels, and two-stories that were built fast to meet suburban demand. Those homes are aging now, and their bathrooms, basements, and layouts show it.
Winters here are cold and wet, with freeze-thaw cycles that crack concrete, push moisture into basements, and wear down bathroom tile grout faster than most homeowners expect. Summers bring humidity that punishes any basement without proper waterproofing behind the drywall. The homes in this zip code need contractors who understand what that climate does to a house over 40 or 50 years.
