What Chicago homeowners should know

Chicago's harsh winters, frequent freeze-thaw cycles and lake-influenced weather are hard on roofs, masonry and plumbing. The city's classic housing — brick two-flats, three-flats, workers' cottages and bungalows built from the late 1800s through the 1930s — almost always has a full basement.

Heavy summer storms can overwhelm the combined sewer system and push water back into basements, so basement flooding is one of the most common and expensive repairs in the city. Backwater valves, overhead sewers and sump pumps are common upgrades.
