Deerfield's 1960s-1980s colonials, ranches, and split-levels used hard machine-pressed brick that still has useful life - but two specific failure modes are producing brick unit damage that tuckpointing cannot fix: steel lintel corrosion above windows and doors, where expanding rust physically displaces and cracks the brick course above the opening, and chimney crown failure, where cracked crowns allow water to saturate and spall upper-course chimney bricks from inside. Delta Tuckpointing is 8 miles from Deerfield, a short drive from our Libertyville office.
Lintel rust and crown failure: the two brick repair drivers in Deerfield
Deerfield grew rapidly during the 1960s through 1980s, and its residential housing stock reflects that era: well-built colonials, ranches, and split-levels with hard machine-pressed brick that has held up through 40 to 60 winters. The median home dates to around 1970. The brick itself is sound, but two specific brick unit failure modes are now appearing at age-predictable rates across the village.
Brick repair - replacing the unit rather than just the joint - is the right intervention when a brick has physically cracked, shifted, or spalled. The two patterns driving brick repair calls in Deerfield are distinct enough that the diagnostic step is critical: identifying whether the unit is failing from lintel expansion below it or from crown-driven moisture inside a chimney determines both the repair scope and what additional work must accompany the brick replacement.
How Deerfield brick fails
The most structurally significant brick failure in Deerfield is displacement and cracking driven by steel lintel corrosion. Steel lintels bear the brick load above each window and door opening. After decades of moisture exposure, these lintels rust. Corroding steel expands significantly, pushing the masonry above the lintel outward. On Deerfield colonials near Deerfield Road from the 1970s, this pattern is visible as a bulge or outward shift in the brick course directly above windows and as cracks radiating from the corners of window and door openings. The displaced bricks are under active stress: simply repointing the mortar around them without replacing the lintel will not hold. The expanding steel will reopen the joint within one season. The correct repair is lintel replacement, followed by resetting the displaced and cracked brick units in fresh mortar.
The second brick failure mode is chimney unit spalling from crown deterioration. Thin, unreinforced chimney crowns on homes from the 1960s and 1980s crack at predictable 40-year intervals. A cracked crown admits water directly into the flue, bypassing the exterior mortar joints. That water saturates the upper-course chimney bricks from inside. In winter, freeze-thaw cycling acts on the moisture inside the brick unit and cracks the face. The visible result is spalled faces on the upper chimney courses - failure that starts at the interior surface and works outward.
Deerfield's tree-lined streets add a third contributing factor. Shade from dense canopy extends moisture duration on north-facing walls. Brick on these shaded elevations stays damp longer after rain and snowmelt, cycling through more freeze-thaw events per winter than the same brick on the exposed south facade of the same house. North wall spalling appears earlier and progresses faster on the most canopy-shaded Deerfield streets.
Matching Deerfield's brick
Hard machine-pressed brick from the 1960s-1980s is more uniform in color, texture, and dimension than pre-war soft common brick. The narrower color range and consistent surface character of post-war production brick make manufacturer matching a realistic first sourcing option for Deerfield homes. Regional brick manufacturers from that era documented their product lines, and production records can sometimes identify a current or discontinued product that matches closely enough for repair work.
Where manufacturer records do not produce a match, salvage brick from post-war Chicago-area construction provides the alternative. The harder, more regular character of post-war machine-pressed brick makes salvage matching more straightforward than the variable tones and textures of pre-war soft common brick.
Deerfield brick repair cost: lintel, chimney, and per-unit pricing
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 above a window or door runs $2,000 to $5,000 depending on the number of openings and extent of displacement. Chimney upper-course brick replacement as part of a crown repair and tuckpointing project is quoted per scope after roof-level inspection. Every project gets a free written estimate before work begins.
An illustrative Deerfield project: a 1975 colonial near Deerfield Road had displaced brick above three windows from rusted steel lintels and 5 spalled upper-course chimney bricks from a cracked crown. Both repairs were completed in the same mobilization - lintel replacement, brick reset and replacement, crown rebuild, and chimney tuckpointing. Identifying both root causes before pricing was what made the repair durable. Delta is 8 miles from Deerfield, approximately 14 minutes from our Libertyville office.
