Our Chimney Cap & Crown Services in Harvey
Crown Repair
Crown repair is the most common call we get from Harvey’s 1920s-1950s bungalows. The original lime-mortar crowns on these chimneys were never designed to last a century without maintenance. After decades of Chicago’s freeze-thaw cycles, they crack, flake, and wash out. Water follows those cracks straight into the flue, spalling interior tile and rusting dampers. We grind out the damaged material, reform the crown with proper slope and overhang, and seal it with HeatShield crown coating. A typical crown repair in Harvey runs $340-$580.
Multi-Flue Cap Installation
In Harvey’s multi-unit two-flats, shared chimneys serving both furnace and fireplace flues in a single masonry stack frequently develop cross-contamination and blockages that go unnoticed until a tenant reports a CO or smoke issue, making full flue separation inspection a standard part of our cap and crown service here. A properly sized multi-flue cap with separation barriers stops debris migration and keeps each flue independent. We recently worked on a 1920s brick bungalow on 155th Street where the original terra-cotta crown had cracked, letting water seep into the flue and spall the interior tile. We replaced it with a custom DuraFlex stainless steel multi-flue cap and coated the crown with HeatShield’s crown sealer to protect against Harvey’s severe freeze-thaw cycles. Multi-flue cap installation in Harvey typically costs $420-$750.
Crown Coating
For Harvey chimneys where the crown is structurally sound but weathered, crown coating buys another decade of protection. We apply HeatShield’s flexible crown sealer, which bridges hairline cracks and repels water while allowing the masonry to breathe. This matters in Harvey, where the Chicago-area freeze-thaw cycle - with temperatures swinging across freezing dozens of times per winter - is particularly destructive to the aging soft-brick and lime-mortar chimneys common in Harvey, accelerating spalling and joint erosion that must be identified during every cleaning visit. Crown coating runs $280-$420 in Harvey.
Cap Replacement
Missing or improperly sized caps are everywhere in Harvey. Some blew off in a storm years ago and were never replaced. Others were installed by a previous owner who guessed at the size. An oversized cap on an oil-to-gas conversion flue traps condensation, accelerating liner spalling in oversized masonry chimneys. We measure your flue precisely and fabricate or stock the correct cap from Gelco or Copperfield. Standard cap replacement in Harvey: $180-$340.

Common Chimney Cap & Crown Problems We See in Harvey Homes
- Original lime-mortar crowns on 1910-1955 bungalows crumble after decades of Chicago freeze-thaw cycles without maintenance. These crowns were poured with weak mortar mixes and no reinforcement. By the time a Harvey homeowner notices a leak inside, the crown has already failed structurally. We inspect for this on every call.
- Improperly sized caps on oil-to-gas conversion flues trap condensation, accelerating liner spalling in oversized masonry chimneys. Many Harvey homes converted from oil to gas heating in the 1960s-80s without chimney relining, leaving oversized flues prone to condensation, acidic byproduct buildup, and interior liner spalling. The wrong cap makes this worse by restricting airflow.
- Shared multi-flue stacks in two-flats lack proper separation caps, allowing debris and cross-contamination between furnace and fireplace flues. Without a multi-flue cap with separation barriers, squirrels nest in one flue and their debris blocks the other. Or furnace exhaust pressurizes a fireplace flue. We’ve found both.
- Missing caps leave flues open to rain, snow, and animal entry. In Harvey’s older neighborhoods, it’s common to find flues that have been open for years. The resulting water damage to fireboxes, dampers, and liners is extensive and expensive. A $200 cap prevents thousands in rebuild costs.

FAQs - Chimney Cap & Crown in Harvey
Harvey’s bungalows were built with lime-mortar crowns and soft brick that weren’t designed for a century of freeze-thaw abuse. Newer suburbs use harder brick, Portland cement crowns, and often have flue liners from day one. The original crowns in Harvey have simply reached end of life. Call (888) 289-6055 for a free inspection - we’ll show you photos of exactly what’s happening up there.
Yes. A properly sized multi-flue cap with separation barriers stops cross-contamination between furnace and fireplace flues in shared stacks. In Harvey’s two-flats, this is critical because a blocked furnace flue can backdraft into a neighboring unit. We inspect shared stacks for separation integrity on every cap and crown job. Call (888) 289-6055 to schedule - estimates are free.
It can. Oil-to-gas conversions often left oversized flues that run cooler and wetter than designed, producing acidic condensation that attacks mortar from the inside. The exterior crown may look intact while the flue interior deteriorates. We use level-2 camera inspection to check this. Crown coating or repair plus a properly vented cap solves most cases. Call (888) 289-6055 for an exact assessment.
A quality stainless steel cap lasts 15-25 years in Harvey’s climate. Galvanized steel caps often fail in 5-8 years. We see plenty of rusted-through caps on Harvey chimneys that should have been replaced a decade ago. If your cap is older than your memory of installing it, it’s worth checking. Call (888) 289-6055 - we’ll inspect it at no charge.
Yes. Many Harvey chimneys have non-standard flue sizes, multiple flues at odd spacing, or exterior dimensions that don’t match modern catalogs. We measure on-site and fabricate custom caps from DuraFlex or Copperfield components, usually installed same-day or next-day. Custom caps in Harvey run $420-$750 depending on complexity.
