Des Plaines sits along the Northwest Highway corridor a short drive from our Park Ridge office. Chimneys here span 150 years of growth from village incorporation through O'Hare-era expansion.
Des Plaines was incorporated as a village in 1869 and chartered as a city in 1925. The city now houses approximately 58,000 residents across four ZIP codes in Cook County. O'Hare International Airport sits along the western city limits, and Northwest Highway runs through the heart of the city, the same corridor where our Park Ridge office is located.
Housing stock spans late-1800s farmhouses, 1920s bungalows, postwar Cape Cods and ranches from the 1940s through 1960s, and continuing infill construction through the 2000s.
Each architectural period in Des Plaines has predictable chimney failure modes after enough decades of weather. Here is what to look for.
Some of the oldest chimneys in our service area exist in older Des Plaines neighborhoods. Original lime-mortar joints have lost binder. Type N (ASTM C270) lime-rich mortar is the only safe repointing match for this 130-plus-year-old brick.
Center-of-roof chimneys serving multiple flues need careful flue isolation during inspection. NFPA 211 Level 2 video scan is essential before any major repair to identify which flue serves which appliance.
Side-of-house exterior chimneys take maximum freeze-thaw exposure. In Des Plaines mortar joints and flashing fail before the brick itself. Repointing on a 30 to 40 year cadence is normal for this stock.
Many newer Des Plaines homes use prefabricated metal flues with manufactured chimney chases instead of structural masonry. These need annual NFPA 211 Level 1 inspection, chase cover replacement, and cap replacement, not the structural repair common in older stock.
Most Des Plaines chimneys can be repaired rather than replaced. The decision usually comes down to four structural questions answered on site.
