Justice sits just southwest of Chicago along the Des Plaines River corridor, a compact village where nearly every street is lined with 1950s-1970s brick ranch and raised-ranch homes built for working families. Those original chimneys were sized for coal and oil furnaces, not the gas systems most homeowners run today. That mismatch - oversized flues, unlined masonry, decades of acidic condensate - is the single biggest reason Justice homeowners call us for crown repair and custom cap installation. We’ve replaced hundreds of deteriorated crowns on 79th Street, 83rd Street, and throughout the 60458 ZIP code. When we say we’ll be there when we say, we mean it.

Our Chimney Cap & Crown Services in Justice
Crown Repair
Crown repair is our most frequent call in Justice, and there’s a reason specific to this village. When homeowners here converted from coal or oil to gas heating - most did so in the 1970s and 1980s - the original oversized flues were rarely relined. Gas exhaust doesn’t generate enough heat to draft properly through those wide chimneys. The result: acidic condensate pools at the crown, corroding mortar and clay tile from the inside while freeze-thaw cycles attack from the outside. We see it on virtually every Justice job. Our crown repair removes deteriorated material, reforms the crown with proper slope and overhang, and seals it against the moisture that rolls in from the Des Plaines River corridor. Done right - and we stand behind it.

Custom Cap Installation
Standard box-store caps don’t fit Justice’s problem. Those oversized, unlined flues need custom caps engineered for the actual opening, with proper screening and a lid that sheds water away from the crown. We measure on-site, fabricate to spec, and install caps that account for the real dimensions of these 50-70-year-old chimneys. A self-reliant homeowner might bolt on a wire-mesh cap from the hardware store. We’ve pulled dozens of those off Justice chimneys, rusted and undersized, having accelerated the very decay they were supposed to prevent. Our custom caps use professional-grade materials from DuraFlex and Gelco, sized for your flue, not a generic approximation.

Crown Coating
For crowns with surface deterioration but sound structural integrity, crown coating extends service life significantly. In Justice’s climate - that relentless freeze-thaw cycle crossing 32°F dozens of times each winter - an uncoated crown absorbs water, expands, contracts, and cracks within a few seasons. We apply Gelco waterproof crown coating after proper surface preparation, creating a flexible barrier that moves with the masonry. It’s not a substitute for crown repair when the structure is failing. It is a smart preventive measure for crowns that are sound but aging. We’ll tell you which category yours falls into, with photos you can see.

Cap Replacement
Cap replacement in Justice often follows the same story: a homeowner installed a cap years ago, it was never quite right for the oversized flue, and now it’s rusted, wind-damaged, or creating moisture traps. We remove the old unit, inspect the crown beneath (damage often hides under a bad cap), and install a replacement that fits. Our crews carry common sizes and can fabricate custom caps on short notice. Most cap replacements in Justice are completed in under two hours, with the 90-Day Done Right Promise backing every installation.

Trusted Brands We Service in Justice
We work exclusively with professional-grade materials - no builder-grade substitutes that fail in Chicago winters. For Justice’s demanding conditions, we specify DuraFlex stainless steel caps and liners, Gelco waterproof crown coatings, and Olympia Chimney components where the job calls for them. These are brands engineered for freeze-thaw corridors and acidic flue gas, not mild climates. We stock local inventory for fast turnaround, so Justice homeowners aren’t waiting weeks for a part to ship. When we say most jobs complete in a single visit, that readiness is part of it.
Common Chimney Cap & Crown Problems We See in Justice Homes
- Condensate-corroded crowns from oversized flues. The gas furnace in your 1960s ranch produces water vapor and mild acids that pool in the wide, cool flue. Over decades, this eats the crown mortar from the inside while the surface looks merely weathered. We pull off crowns that seem intact until you probe them.
- Freeze-thaw separation at the flue tile joint. Justice’s position in the Chicago metro freeze-thaw corridor means crown mortar expands and contracts dozens of times each winter. Eventually the crown separates from the flue tile, opening a direct water entry path. The Des Plaines River moisture in the air makes it worse.
- Undersized wire-mesh caps trapping moisture. Self-reliant homeowners often install hardware-store caps that are too small, too flat, or too porous. They don’t shed water properly, they rust through in a few seasons, and the mesh clogs with debris. We replace these with properly engineered caps that ventilate without admitting rain.
- Spalling brick faces and efflorescence below the crown. When the crown fails, water runs down the chimney exterior. In Justice’s moisture-heavy air, that water carries salts to the surface, leaving white efflorescence and causing brick faces to flake off. The damage is visible from the ground - and it starts at the crown.

FAQs - Chimney Cap & Crown in Justice
Yes. The original flue in your Justice ranch was built for coal or oil exhaust, which is hotter and more voluminous than gas. A standard cap sized for modern gas flues will leave gaps or create draft problems. We fabricate custom caps for these oversized openings, with proper screening and water-shedding design. Call (888) 289-6055 and we’ll measure your flue on-site - estimates are free.
Every year, ideally before winter. Justice’s location in the freeze-thaw corridor, combined with above-average moisture from the Des Plaines River, accelerates crown deterioration. An annual Level-2 camera inspection with photos lets you catch separation at the flue tile or condensate corrosion before water enters the masonry. Our $89 seasonal tune-up includes this inspection.
It can, if the crown structure is still sound. Crown coating is preventive, not restorative. We apply Gelco waterproof coating after cleaning and minor crack repair, creating a flexible barrier against Justice’s freeze-thaw cycles. For a crown that’s already separating from the flue tile or significantly spalled, repair or replacement is the honest recommendation. We’ll show you photos and tell you which category you’re in.
Natural gas combustion creates water vapor and carbonic acid. In a properly sized, lined flue, the exhaust stays hot enough to carry these out the top. Your Justice ranch’s oversized, unlined flue was built for coal - much hotter exhaust. The gas exhaust cools too quickly, condenses on the flue walls and crown, and that acidic water eats mortar from the inside. It’s the single most common hidden damage we find in Justice chimneys. The fix is proper relining and a cap engineered for the actual flue size.
Usually yes. Wood stove flues run hotter and handle different exhaust than gas furnace flues, but the cap principles are similar: proper fit, adequate screening to prevent sparks and debris entry, and water-shedding design. If your workshop chimney is also an older masonry unit, it may have the same oversized-flue issue. We can inspect both in the same visit and spec the right cap for each application. Call (888) 289-6055 to schedule - estimates are free.
