About this city

Highwood chimneys, by the numbers

Highwood was incorporated in 1886 and houses approximately 5,000 residents in Lake County along the Lake Michigan shore. The compact city sits between Lake Forest and Highland Park.

Housing concentrates in 1890s through 1940s construction with substantial Italianate, Tudor Revival, and bungalow styles. Lake Michigan proximity drives freeze-thaw cycling.

By era

Common Highwood chimney problems by housing era

Each architectural period in Highwood has predictable chimney failure modes after enough decades of weather. Here is what to look for.

1880s-1910s

Late Victorian and Queen Anne

Original lime-rich mortar joints in Highwood's oldest chimneys have lost binder over more than a century of weather. Tuckpointing requires Type N (ASTM C270) lime-rich mortar to match. High-Portland-cement mortar will spall the historic brick within five to ten years.

1900s-1940s

Lakefront masonry estate

Tall slender chimneys with decorative caps and corbels in Highwood take maximum wind and lake moisture exposure. Crown rebuilds often require structural repair below the crown, not just cap-and-seal, plus original brick salvage to preserve architectural integrity.

1920s-1930s

Tudor Revival

Decorative chimney corbels and ornate caps deteriorate first because they extend beyond the main flashing line. Crown rebuilds in Highwood's historic neighborhoods often require salvaging or matching original brick to preserve curb appeal.

1930s-1950s

Cape Cod and Colonial Revival

Center-of-roof chimneys with heavy postwar use show creosote-glazed flue tile and crown cracks. Annual NFPA 211 Level 1 inspection plus crown sealing is the right cadence for this stock in Highwood.

Decision aid

Repair or replace, how we decide

Most Highwood chimneys can be repaired rather than replaced. The decision usually comes down to four structural questions answered on site.

Repair when
  • Mortar joints are deteriorated but the brick itself is sound
  • Crown is cracked but the underlying structure holds plumb
  • Cap is rusted or missing but flue tile is intact
  • Flashing leaks but the chimney has no settlement cracking
Replace when
  • Brick is spalling across more than 30 percent of the chimney face
  • The chimney is leaning, settling, or pulling away from the house
  • Flue tile is cracked, displaced, or missing in multiple places
  • Internal liner has corroded through and chimney is unlined

Highwood FAQs

Questions from Highwood homeowners

Highwood is approximately 40 to 50 minutes drive from our Park Ridge office. Inquiries received during business hours are typically returned within two hours and inspection windows are usually available within one to two business days. Active leaks should be called in directly to (847) 685-1043 for priority dispatch.
The Highwood Building Department requires permits for structural chimney rebuilds, full chimney replacements, and changes that alter the flue path. Routine repairs such as tuckpointing, crown sealing, cap replacement, and cleaning generally do not require a permit. We pull and manage permits on permit-required jobs.
East-facing chimney exposures cycle through freeze-thaw 30 to 50 percent more often than inland Lake County. Annual NFPA 211 inspection is essential.
Yes. Highwood has substantial late-Victorian and Italianate housing stock that requires lime-rich Type N mortar (ASTM C270) for repointing and crown rebuilds. Mismatching with modern Portland-heavy mortar damages original brick within 5 to 10 years. We match mortar by sample on historic homes.
Highwood's lakefront pre-WWII stock needs Type N mortar matching, structural crown rebuilds, and flashing replacement. Annual inspection is essential.
