Highland Park's housing stock spans soft-brick Colonials and Tudors from the 1920s-1940s near Ravinia through mid-century ranches and split-levels to 1990s construction. Brick repair here focuses on two distinct problems: spalling on pre-war soft common brick where Portland cement repairs trapped moisture inside the unit, and foundation-level displacement on ravine-adjacent properties where shifting soil cracks and dislodges bricks near grade. Delta Tuckpointing serves Highland Park from our Libertyville office, 10 miles away.
Two eras, two failure modes: brick repair on Highland Park's pre-war and post-war homes
Highland Park spans a wider construction range than almost any other community we serve. Homes near Ravinia and the lakefront were built in the 1920s through 1940s with soft Chicago common brick - the same hand-pressed material used across the North Shore during that era. Inland ranches and split-levels from the 1950s-1970s used harder machine-pressed brick. And 1980s-1990s colonials represent a third generation. The median home dates to around 1958.
Brick repair - the replacement of cracked, spalled, or displaced brick units themselves - is distinct from tuckpointing, which restores only the mortar joints. On Highland Park's pre-war soft brick homes, the primary repair need is spalled units: bricks whose outer face layer has fractured and separated. On ravine-adjacent homes, the primary repair need is displaced or cracked foundation-level bricks driven by soil movement.
The mortar used to set replacement bricks must match the original for that home's era: Type N lime-based mortar for the pre-war soft brick near Ravinia, Type S for the harder post-war brick further inland. Getting this wrong causes new damage to the surrounding units.
How Highland Park brick fails
The most common cause of brick spalling on Highland Park's pre-war stock is the legacy of incorrect Portland cement repairs applied in the 1960s through 1980s. Portland cement mortar is harder than soft Chicago common brick. It blocks the moisture vapor path that the original lime mortar system relied on: instead of escaping through the joint, water accumulates inside the brick. When that water freezes overnight, it expands, and the brick face cracks and separates in layers. The mortar joint beside the failing brick can look intact and recently repaired while the brick unit beside it deteriorates. This is the pattern we see on many of the older homes near Ravinia and the lakefront.
The second Highland Park failure mode is ravine-adjacent foundation displacement. The city's terrain includes significant grade changes and deep ravines. Homes near ravine edges sit on soils that shift more than flat suburban lots - frost heave in winter and saturation during heavy rain cause differential movement that stresses foundation masonry. Foundation-course bricks crack and shift outward, and stair-step cracking in the mortar joints above them is the visible signal that the wall is responding to soil movement rather than simple weather exposure.
North-facing facades compound both patterns. Minimal sunlight and lake-influenced humidity keep north walls damp longer than any other elevation, driving more freeze-thaw cycles per winter on the most exposed brick faces.
Matching Highland Park's brick
For the pre-war soft common brick homes near Ravinia, replacement must come from salvage: this brick has not been manufactured for decades, and modern face brick is harder, more uniform in color, and dimensionally different from the hand-pressed common brick it would need to blend with. The color range on pre-war Highland Park common brick includes warm buffs, reds, and mottled blends that require careful salvage yard sourcing and comparison against the existing wall in natural light before any unit is installed.
For mid-century machine-pressed brick on Highland Park's inland ranches and split-levels, manufacturer matching may still be possible for homes from the 1960s-1970s. Where manufacturer matching is not achievable, salvage material from the same era and region provides an adequate match for the harder, more uniform post-war brick profile.
The Portland cement legacy on many pre-war homes means the repair scope often includes two steps: removing the incorrect hard mortar from surrounding joints and replacing damaged brick units. Removing the mortar source that caused the original spalling stops new units from failing while the replacement bricks are being integrated into the wall.
Highland Park brick repair: pricing across two generations of construction
Single brick replacement runs $50 to $150 per brick in the Chicagoland market. Section repair for 10 to 30 bricks runs $500 to $2,000. Lintel replacement with brick reset runs $2,000 to $5,000. Projects involving foundation-course repair on ravine-adjacent homes may include drainage work in addition to unit replacement, priced per project. Every project gets a free written estimate before work begins.
An illustrative Highland Park project: a 1936 Colonial near Ravinia had 11 spalled bricks on the north facade, all at the joint line - the signature of Portland cement mortar trapping moisture in soft brick. The repair required removing the hard cement from surrounding joints, sourcing salvage soft common brick in a matching buff-red tone, and resetting the replacement units in Type N lime mortar. Delta is 10 miles from Highland Park, approximately 18 minutes from our Libertyville office.
