We’ve been driving to Griffith for over 42 years, from our founding in 1984. We know the difference between a bungalow east of Broad Street built in 1952 and a ranch near Wiggs Street from 1967. That matters because the chimneys were built for different fuels, different appliances, and different lives. Our technicians carry the equipment to document what they find with a Level-2 camera inspection, explain it in plain English, and fix it on the spot when possible. Most Griffith jobs finish in one visit.

Crown Repair
Crown repair in Griffith usually costs $280-$450 and addresses the most common failure we see on mid-century bungalows. The original mortar crown, poured decades ago over an oversized flue, cracks under Lake Michigan’s freeze-thaw assault. Water seeps through, freezes, expands, and opens the crown further. We remove the damaged material, form a new sloped crown with proper overhang and drip edge, and seal it with a professional-grade crown coating. Last spring we replaced a cracked, unlined clay crown on a 1954 brick bungalow on East Broad Street; the original coal-era flue was 12×12, far too large for the modern gas furnace, and the crown had spalled from freeze-thaw moisture wicking through the oversized chase. We installed a new poured-in-place mortar crown and a copper multi-flue cap to prevent further water infiltration and improve draft.

Multi-Flue Cap Installation
Multi-flue caps run $340-$580 installed in Griffith and solve a problem specific to this area’s older housing stock. Many bungalows here have two or three flues in a single chimney structure, one for a furnace, one for a water heater, sometimes one for a fireplace. Homeowners often use only one flue regularly, leaving the others open. Birds nest in them. Leaves collect. Rain pours straight down. A multi-flue cap covers the entire chimney top with a single shelter, improving draft on all flues and keeping debris out. We size them precisely and install them with stainless steel or copper options from Gelco and Olympia Chimney.

Crown Coating
Crown coating is $180-$320 in Griffith and buys time when the crown is cracked but structurally sound. We don’t recommend coating over failure, but when caught early, a flexible, breathable sealant from HeatShield can add five to ten years of protection. This is particularly valuable on Griffith’s 1960s ranches where the crown is beginning to show hairline cracks from freeze-thaw but hasn’t yet spalled significantly. We inspect first, document with photos, and give you an honest verdict on whether coating will hold or if replacement is the smarter spend.

Cap Installation & Replacement
Single-flue cap installation in Griffith ranges $140-$260, while replacement of a rusted or damaged cap runs $120-$220. The right cap keeps rain, animals, and debris out while allowing proper venting. On Griffith’s older chimneys, we often find caps that were added as an afterthought, poorly sized, or installed without proper clearance. We measure the flue, check draft requirements, and install caps from DuraFlex and Copperfield that fit correctly and last.

Trusted Brands We Service in Griffith
We work exclusively with professional-grade materials, no builder-grade substitutes. For Griffith’s harsh winters and industrial-housing challenges, we specify DuraFlex stainless steel caps, HeatShield crown repair systems, and Gelco multi-flue shelters. These are the brands that hold up when Lake-effect moisture drives repeated freeze-thaw cycles through your chimney. We stock common sizes and configurations locally, so most Griffith customers don’t wait for special orders. When we find a cracked crown on inspection, we can often repair it same-day rather than scheduling a return trip.
Common Chimney Cap & Crown Problems We See in Griffith Homes
- Oversized flues from coal-to-gas conversions cause condensation and acidic runoff that eats mortar crowns from within. The original 12×12 or 10×10 flues built for coal furnaces were never relined when homeowners switched to gas in the 1970s and 80s. Gas exhaust is cooler and wetter, so it condenses on the oversized clay tiles, runs down, and pools on the crown. The acidic condensate dissolves mortar from the inside out. We find this on almost every inspection east of Broad Street.
- Lake-effect freeze-thaw cycles crack uncoated mortar crowns, letting water into the flue liner and accelerating spalling. Griffith sits roughly 12-15 miles south of Lake Michigan, close enough to catch serious moisture in winter. A crown that looks fine in October can have open gaps by March. Water gets in, freezes, expands, and opens the cracks wider. By the second winter, chunks of crown are falling into the firebox.
- Missing or undersized caps on multi-flue chimneys allow birds and debris to block the oversized openings near Broad Street. We pull nests, leaves, and even dead squirrels from flues that haven’t been capped properly. A blocked flue backs up carbon monoxide into the house. The multi-flue caps we install prevent this entirely.
- Original terra-cotta flue liners crack from thermal shock and acid attack, then the crown above them loses structural support. Once the liner cracks, the crown has nothing solid beneath it. It flexes, cracks, and fails faster. We inspect the liner as part of every crown evaluation because fixing the crown without addressing the liner is temporary at best.

FAQs - Chimney Cap & Crown in Griffith
Patching works only when the crown has minor surface cracking and the underlying structure is sound. Most 1950s bungalows in Griffith have crowns that have already spalled significantly from decades of freeze-thaw and, often, acidic condensate from an oversized gas flue. We inspect with a camera, show you photos, and give an honest verdict. When the crown is crumbling or the flue liner beneath it is cracked, replacement is the only repair that lasts. Call (888) 289-6055 for a free inspection and written estimate.
The unused flues still need protection. Rain, snow, leaves, and animals enter open flues, then cause blockages, moisture damage, and odor problems that affect the entire chimney structure. In Griffith’s older housing stock, multi-flue chimneys are common, and the oversized openings from original coal-era construction make them especially vulnerable. A multi-flue cap covers all flues with a single shelter, improves draft, and prevents the failure pattern we see repeatedly on inspections east of Broad Street. Call (888) 289-6055 to discuss sizing and options.
Yes, and it’s a specific problem in Griffith. Oil furnaces run hotter and draft more aggressively through larger flues. Gas furnaces run cooler and produce wetter exhaust. When the flue wasn’t relined after conversion, the gas exhaust moves too slowly, condenses on the clay tiles, and runs down to the crown. The acidic condensate eats mortar from the inside while Lake-effect moisture attacks from outside. Technicians in Griffith regularly find this exact failure mode. We evaluate the flue size against the appliance output and recommend relining when the mismatch is causing crown damage. Call (888) 289-6055 for an assessment.
Every year, before heating season begins. Griffith’s freeze-thaw cycle is aggressive, a crown that was intact in September can be cracked by February. Annual inspection catches crown damage early, when coating or minor repair still works. Wait two years, and you’re often looking at full replacement. We offer an $89 seasonal tune-up that includes crown inspection, flue evaluation, and a plain-English verdict with photos you can see. Call (888) 289-6055 to schedule.
The crown sits above the flue tiles and doesn’t need to match them visually, but we can preserve the aesthetic of your chimney top. For Griffith’s brick bungalows where curb appeal matters, we form new crowns with clean lines and proper proportions, and we offer copper caps that weather to a classic patina. The clay flue tiles themselves, if exposed, are protected by the cap and crown working together. We document everything with photos so you see exactly how the finished work will look. Call (888) 289-6055 to discuss materials and appearance.
