We’ve been working on Hammond chimneys since 2014. We know the Hessville bungalows with their alley-load access and narrow driveways. We know the Robertsdale two-flats where technicians before us have tried standard caps on oversized clay-tile flues and failed. Our Chimney Cap & Crown team doesn’t guess at what’s needed. We inspect with a camera, show you the photos, and tell you straight what the fix is and what it costs before we start.
Why Hearthstone Chimney Co. of Chicago Is Hammond’s Preferred Chimney Cap & Crown Company
Hammond homeowners call us back because we document what we find and stand behind what we do. Over 42 years, we’ve built a reputation in Lake County and the Calumet region for showing up when we say we will and fixing the actual problem, not the symptom.
Our reviews from Hammond customers consistently mention two things: the photos they can see and understand, and the fact that we don’t leave until the job is done right. The 90-Day Done Right Promise means if something isn’t right, we come back. In writing. No arguing.
Response time to Hammond is typically same-day or next-day. We’re familiar with the parking constraints around downtown Hammond, the alley access behind Hessville homes, and the narrow lots that require roof-based rigging rather than standard ladder setups. That local knowledge saves time and prevents damage to your property.
We also understand the specific failure patterns in Hammond’s housing stock. The 1920s-1940s brick bungalows built for steelworkers weren’t designed for modern gas appliances. Their oversized flues, abandoned secondary vents, and century-old clay tile create problems that a technician from outside the Calumet region simply won’t recognize. We do. We’ve seen them hundreds of times.
Our Chimney Cap & Crown Services in Hammond
Cap Installation
New cap installation in Hammond requires more thought than in newer markets. Many homes in the 46324 and 46327 ZIP codes have dual-flue chimneys originally built for coal. A standard single-flue cap won’t work. We measure every flue, active or abandoned, and specify caps that cover the full chimney top. Our technicians carry Gelco and Copperfield multi-flue caps on their trucks for common configurations. Installation typically takes 1-2 hours, and we finish by sealing the crown base to prevent the freeze-thaw spalling that Hammond’s lake-effect winters accelerate.
Cap Replacement
Caps in Hammond fail faster than in inland communities. The lake-effect snow belt delivers more freeze-thaw cycles per winter, and galvanized caps on homes near the 46320 corridor often rust through in 5-7 years. We replace them with stainless steel or copper options from Olympia Chimney and Copperfield, sized correctly for your flue system. If your old cap was letting water into an abandoned coal-range flue, we’ll address that too. The new cap goes on, the secondary flue gets proper coverage, and you stop worrying about squirrels in your chimney.
Crown Repair
Crown repair is the most common cap-and-crown call we get in Hammond. The combination of original concrete crowns poured in the 1930s-1950s, aggressive freeze-thaw cycling, and acidic condensation from oversized gas flues destroys these surfaces from above and below. We grind out the damaged concrete, apply a bonding layer, and pour a new sloped crown with proper drip edges. For crowns with moderate spalling but sound structure, we offer crown coating with professional-grade materials that seal cracks and restore slope. Either way, we document the before condition with photos and give you a plain-English verdict on whether repair or full replacement makes sense.
Crown Coating
Crown coating is a practical option for Hammond homeowners whose crowns are cracked but not structurally failed. The coating we use is formulated for the thermal cycling and moisture exposure that Hammond chimneys endure. It fills hairline cracks, restores the protective slope, and adds a waterproof barrier. We don’t recommend coating over crowns that are severely spalled or where the underlying concrete is deteriorated. Our camera inspection shows you which category you’re in. A typical crown coating in Hammond runs $280-$450 and adds 10-15 years of service life when the underlying crown is sound.
Custom Cap
Hammond’s non-standard flue configurations demand custom solutions. On older Hessville and Robertsdale streets, we regularly encounter chimneys with one active flue and one abandoned flue offset by several inches, or flues of different diameters side by side. Stock caps won’t fit. We fabricate custom caps from copper or stainless steel, measured to your exact chimney top, with screening sized to keep out animals while allowing proper draft. A custom cap in Hammond typically costs $450-$850 installed, depending on metal choice and complexity. We template on-site and deliver finished caps within 5-7 business days.
Multi-Flue Cap
Multi-flue caps are our standard recommendation for Hammond’s dual-flue chimneys. One cap covers all flues with a single sloped roof, eliminating the gaps between individual caps where water and debris collect. We size multi-flue caps from Copperfield and Gelco to overhang the chimney crown by at least 2 inches on all sides, directing water away from the brickwork. For chimneys with both active and abandoned flues, the multi-flue design ensures nothing gets in anywhere. Installation includes sealing the crown perimeter and verifying that all flues have adequate draft clearance.

Common Chimney Cap & Crown Problems We See in Hammond Homes
- Abandoned secondary flues left uncapped. In Hessville and Robertsdale, many chimneys were built with dual flues for coal furnaces and kitchen ranges. The secondary flue was abandoned decades ago but never properly capped. Rain funnels straight down, mortar joints rot from the inside, and squirrels or raccoons set up residence. We find this on roughly one in three bungalow inspections in Hammond’s 46324 ZIP code.
- Oversized clay-tile flues causing acidic condensation. Flues designed for coal are too large for modern gas appliances. The exhaust cools too quickly, condensation forms on tile walls, and the resulting acidic moisture attacks the crown from underneath while lake-effect weather attacks from above. Crown failure in Hammond is often a two-front problem.
- Freeze-thaw spalling on original concrete crowns. Hammond’s position in the Lake Michigan snow belt means more freeze-thaw cycles than communities just 20 miles inland. Original crowns poured in the 1930s-1950s absorb moisture, freeze, crack, and spall. By the time homeowners notice water in the firebox, the crown is often structurally compromised.
- Improper access damaging property during repairs. Dense housing, alley-load access, and narrow driveways on streets like Olcott Avenue make standard ladder setups impossible or risky. We’ve seen gutters torn off and siding dented by technicians who didn’t plan for Hammond’s physical constraints. Our team works from the roof with custom bracketry when needed.

FAQs - Chimney Cap & Crown in Hammond
They were built for coal. One flue served the basement furnace, the other the kitchen range. When homes converted to gas, the secondary flue was often abandoned but left open. Today those uncapped flues channel water and animals into the chimney structure. We cap both flues, active and abandoned, to protect the masonry. Call (888) 289-6055 and we’ll show you exactly what your chimney has.
Yes, if the tile is structurally sound. We camera-inspect first. Cracked, offset, or missing tile sections need repair before capping, or the cap will trap moisture against damaged surfaces. For Hammond’s century-old clay tile, we often find the upper courses are the most deteriorated. We repair or replace those sections, then install the correct cap. The inspection and estimate are free.
Crown coating works if the underlying concrete is sound and the spalling is superficial. We grind loose material, apply a bonding agent, and coat with a flexible, waterproof material rated for thermal cycling. If the crown is cracked through or the concrete is deteriorated, coating won’t last and we recommend full repair or replacement. We show you the camera photos and give you a straight recommendation. Estimates are free.
Most cap installations and crown coatings do not require a permit in Hammond. Crown replacement or structural masonry repair may need a building permit depending on scope and location. We handle permit research and filing when required, and we build that into our upfront pricing so there are no surprises. Call (888) 289-6055 with your address and we’ll confirm what’s needed.
We work around it. On narrow Hammond lots and alley-load properties, our technicians often stage on the street and carry materials through, or work from the roof with custom bracketry rather than standard ladder setups. We’ve completed cap and crown jobs on Olcott Avenue, throughout Hessville, and on tight Robertsdale lots without damaging gutters, siding, or landscaping. We assess access during the free estimate and plan accordingly.
