Why Hearthstone Chimney Co. of Chicago Is Munster’s Preferred Chimney Cap & Crown Company
We’ve been crossing the state line into Munster for over 42 years, long enough to know which homes on Briarwood Lane were built with coal-era chimneys that never got properly capped, and which subdivisions put up brick ranches in the 1960s with crowns that are just now giving out. Our Chimney Cap & Crown team carries Gelco and Copperfield caps in multiple sizes on every truck, plus the forms and mortar mix for same-day crown pours. That matters in Munster, where a second trip means another day of lake-effect rain or snow getting into your flue.
Munster homeowners call us because we document what we find. Every inspection ends with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your crown only needs a coating, we’ll tell you. If it’s crumbled through to the brick, we’ll show you the photo and give you the full replacement price before we start. Our 90-Day Done Right Promise covers every job in writing - if it’s not right, we come back, no arguing, no paperwork to dig up.
Most of our Munster appointments are completed in a single visit. Our technicians are background-checked, uniformed, and trained to fabricate custom caps on-site when the flue size doesn’t match anything off the shelf. That’s common here.
Our Chimney Cap & Crown Services in Munster
Custom Cap Installation
Munster’s acreage properties are where custom caps prove their worth. Many detached workshops and outbuildings on the larger lots east of Calumet Avenue were built with chimneys sized for coal or fuel-oil equipment - flues that don’t match standard cap dimensions. We measure on-site, fabricate from heavy-gauge stainless or copper, and install the same day. On a recent job in the Briarwood Estates section, our crew installed a custom multi-flue cap from Copperfield on a detached workshop chimney that had no crown at all. We fabricated a heavy-gauge stainless steel cap on-site to match the oversized flue - eliminating years of raccoon intrusion and water damage in one trip. Custom caps in Munster typically run $450-$780.
Crown Repair & Replacement
The crown is the concrete slab that seals the top of your chimney, and in Munster it takes a beating. Lake-effect moisture keeps masonry saturated for months, then freeze-thaw cycles crack the concrete and let water reach the brick below. We see this constantly on the 1950s-1980s colonials near the Centennial Park area and on ranch homes throughout the White Oak Estates neighborhood. Crown coating works for hairline cracks and minor spalling - $280-$420. When the crown has separated from the flue tile or the concrete is crumbling, we remove it to the brick, form and pour a new sloped crown with expansion joints, and seal it - $620-$890. Done right, and we stand behind it.
Cap Replacement
Standard cap replacement is straightforward until it isn’t. Many Munster homeowners discover their “missing” cap was actually never installed - common on chimneys that served oil furnaces or coal stoves where caps weren’t code-required. Others find a cheap galvanized cap from the hardware store has rusted through in three years. We replace with stainless steel or copper caps from Olympia Chimney or Gelco, properly sized and secured. Standard replacements run $180-$340. If your flue is oversized from a coal-era conversion, we’ll spot that during inspection and quote the custom option before we leave.
Multi-Flue Cap Installation
Homes with multiple fireplaces or a fireplace plus a furnace flue need multi-flue caps - one cover that protects several flues with proper clearance and ventilation. We see these on larger Munster properties, especially the two-story colonials near the border with Hammond. Multi-flue caps from Copperfield or Famco run $380-$650 installed, depending on span and material. We measure exact center-to-center flue spacing on-site; an ill-fitting multi-flue cap is worse than none at all.

Trusted Brands We Service in Munster
We stock professional-grade caps and crown materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney on every truck serving Munster. No builder-grade substitutes, no special-order delays. When we pull up to a home on Manor Drive or Ridge Road, we already have the stainless mesh, concrete bonding agents, and custom-fabrication tools to finish that day. Our relationship with Copperfield and Famco means we can source specialty multi-flue covers or copper customs within 48 hours if your job requires something we don’t carry. The brands matter because a cap that fails in five years costs you twice - once for the replacement, once for the water damage it allowed.
Common Chimney Cap & Crown Problems We See in Munster Homes
- Uncapped detached workshop chimneys. Munster’s large-lot acreage properties often include outbuildings with their own chimneys - many originally coal-fired - that were never fitted with caps or crowns. Rainwater and animals enter freely, leading to accelerated freeze-thaw damage and blockages that can back up carbon monoxide into the workshop.
- Crumbling crowns on coal-era chimneys. Original chimneys on Munster’s older acreage homes frequently have crowns eroded by decades of lake-effect moisture. The concrete turns to gravel, exposing the brick courses below to the same saturation-freeze cycle that destroyed the crown.
- Oversized flues causing hidden creosote buildup. Many Munster chimneys were built for coal or fuel-oil appliances and later converted to wood-burning without relining. These oversize flues cool exhaust gas too quickly, depositing glazed creosote at elevated rates. A new cap won’t fix this - we flag it during inspection and recommend relining before capping.
- Raccoon and squirrel intrusion through missing or poorly fitted caps. Munster’s mature tree canopy and proximity to the Little Calumet River corridor means active wildlife. A cap with torn mesh or a flue left completely open becomes a nesting site, leading to blockages, odors, and dead-animal removal calls.

FAQs - Chimney Cap & Crown in Munster
Many detached workshops and outbuildings on Munster’s larger lots have chimneys built for coal or fuel-oil equipment with flue dimensions that don’t match standard cap sizes. We fabricate custom caps on-site to fit these oversized or irregular flues, and we anchor them to withstand the wind exposure that open acreage properties get. Call (888) 289-6055 and we’ll measure yours - estimates are free.
Munster sits close enough to Lake Michigan to receive heavy, sustained winter humidity that keeps masonry saturated for months, followed by repeated freeze-thaw cycles that crack and spall concrete crowns. Crowns that might last twenty years in drier climates often need attention in twelve to fifteen here. Annual inspection catches crown damage before water reaches the brick below.
We can install a cap, but we won’t do it if the flue is oversized for your current appliance - which is common on converted coal chimneys in Munster. An oversize flue cools exhaust too quickly, causing glazed creosote buildup that a cap will hide but not fix. Our Level-2 camera inspection determines flue sizing; if relining is needed, we’ll explain why and quote it together with the cap.
Not necessarily - if the crown beneath is sound, we can replace just the cap. But in Munster we often find that a missing or leaking cap has allowed water to degrade the crown underneath, especially on chimneys that haven’t been inspected in years. We photograph the crown during every cap estimate and show you the condition before you decide.
Most custom cap installations in Munster are completed in two to three hours, including on-site fabrication, fitting, and securing. We bring the sheet metal brake and cutting tools on the truck, so there’s no delay for off-site work. Our goal is one trip, finished, with no follow-up needed.
