Chimney cap and crown repair in Schererville typically runs $280-$890 depending on whether you need a galvanized chase cover replacement, custom cap fabrication, or mortar crown coating on a masonry chimney.

We’ve been driving to Schererville since the mid-1980s, back when the big buildout along US-30 was still fresh and those ranch and split-level homes were new. We know the Hawthorne Hills subdivisions, the streets off Kennedy Avenue, and the pockets near Oak Ridge Prairie County Forest Preserve where the same generation of builder-grade prefab fireplaces is now hitting 30 to 50 years of age. If your chimney cap is dripping rust down the siding or your crown has developed hairline cracks after another hard Lake County winter, call us at (888) 289-6055.

Our Chimney Cap & Crown Services in Schererville
Cap Installation
New cap installation in Schererville is almost always for prefabricated fireplaces that were built without a proper weather cap, or where the original builder-grade cap blew off years ago. We measure your chase opening on-site and fabricate a cap that fits precisely, with proper clearance for draft and spark arrestor mesh where code requires it. For homes near the Oak Ridge Prairie area where wind exposure is higher, we use heavier-gauge materials and reinforced attachment methods.
Cap Replacement
This is our most common call in Schererville. In the 1975-1995 tract-built ranches and split-levels that fill this town, the prefabricated metal fireplaces were fitted with galvanized chase covers that rust through in 5-7 years under lake-effect moisture, far faster than in dry suburbs. So cap replacement here is almost always a full metal chase cover replacement, not just patching a mortar crown. We stock and fabricate replacements in galvanized steel, stainless steel, and copper, with fast turnaround so your chase isn’t open to another rain.
Crown Repair
The few full masonry chimneys in Schererville, mostly in older pockets near the original town center or custom builds off Kennedy Avenue, take a beating from Lake County’s sharp freeze-thaw cycles. Water seeps into hairline cracks, expands overnight when temperatures drop below 20 degrees, and opens those cracks into channels that funnel water straight to the flue liner and firebox. We grind out damaged crown material, apply proper bonding agents, and pour new crown concrete with the correct slope and overhang to shed water away from the brickwork.
Crown Coating
For masonry crowns with minor cracking that hasn’t yet compromised the structural integrity, crown coating extends service life without the cost of full replacement. We use professional-grade flexible coatings that bridge small cracks and create a waterproof membrane while allowing the crown to breathe. In Schererville’s climate, we see this as a smart preventive measure for masonry chimneys that are structurally sound but showing early weathering from lake-effect moisture and repeated freezing.
Custom Cap Fabrication
Standard chase covers don’t fit every prefab system, especially on older units where the original manufacturer is out of business or the chase dimensions were non-standard from the factory. We measure, cut, and form custom caps on-site or in our shop, with proper drip edges, cross-breaking to prevent ponding, and welded seams that outlast snap-together alternatives. For homeowners in Schererville who want to solve this problem once, we often recommend upgrading from galvanized to stainless steel or copper.
Multi-Flue Cap Systems
Some Schererville homes, particularly larger split-levels with basement fireplaces or additions with second flues for furnaces or water heaters, need a single cap system covering multiple flue terminations. We fabricate and install multi-flue caps with proper height differentials and separation to prevent downdraft and cross-contamination between flues.

Trusted Brands We Service in Schererville
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney, no builder-grade substitutes. For Schererville’s prefab fireplace stock, we regularly source DuraFlex chase covers and Gelco cap assemblies that match factory specifications for the metal fireplace brands installed during the 1980s and 1990s buildout. We keep common sizes in stock, which means most Schererville homeowners aren’t waiting two weeks for a special order while lake-effect rain continues dripping into their chase. When we recommend a material, we tell you why, and we show you the difference before you decide.
Common Chimney Cap & Crown Problems We See in Schererville Homes
- Rusted-through galvanized chase covers on 1980s prefab fireplaces. The lake-effect moisture that rolls down from Lake Michigan, roughly 20 miles north, saturates these thin metal covers year after year. Freeze-thaw cycling opens seams and accelerates rust. By the time a homeowner notices water stains on the ceiling near the fireplace, the chase cover is often completely perforated and the surrounding wood framing is compromised.
- Cracked or heaved mortar crowns on full masonry chimneys. The minority of Schererville homes with traditional brick chimneys face sharper freeze-thaw cycles than communities farther from the lake. Crown concrete that was poured without proper slope or control joints cracks within a few seasons, creating direct water paths into the flue system.
- Corroded damper assemblies and firebox components in aging zero-clearance fireplaces. When caps fail or were never installed, rain enters the chase and pools in the firebox or rusts the damper mechanism. In Schererville’s high-humidity environment, this corrosion progresses faster than homeowners expect, and the first symptom is often a damper that won’t open or a firebox with visible rust scaling.
- Improperly flashed or sealed crown-to-chase transitions. On prefab systems, the joint where the chase cover meets the wood or metal chase siding is a common leak point. Builder-grade caulking fails in 2-3 years under UV and thermal cycling. We see this repeatedly in Schererville’s 1990s-era split-levels where the original sealant has long since hardened and cracked.
Pricing for Chimney Cap & Crown in Schererville, IL
Here is what chimney cap and crown work costs in the Schererville market. These are honest ranges based on jobs we’ve completed in the 46375 ZIP code. Your exact estimate depends on chase dimensions, material choice, and access conditions, but these figures give you a solid starting point.

|---|---|

What moves the number? Chase height and roof pitch affect labor time. Custom fabrication for obsolete prefab models costs more than standard sizes. And if we open the chase and find rotted framing from years of undetected leakage, that repair is additional and we’ll show you photos before proceeding. We provide no-hassle upfront pricing, the number on the estimate is the number on the invoice. Call (888) 289-6055 for a free estimate at your Schererville home.

FAQs - Chimney Cap & Crown in Schererville
Galvanized chase covers on 1980s and 1990s prefab fireplaces rust through in 5-7 years in Schererville because lake-effect moisture from Lake Michigan, roughly 20 miles north, creates sustained high humidity and aggressive freeze-thaw cycling that thin galvanized steel simply cannot withstand. In drier Midwest suburbs farther from the lake, these same covers last 12-15 years. If your chase cover is showing orange streaks on the siding, it’s already perforated. Call (888) 289-6055 for a free inspection, estimates are free.
Prefabricated metal fireplaces do not have masonry crowns; they have chase covers, which are metal caps that seal the top of the chase. Your 1988 unit almost certainly needs a chase cover replacement, not crown work. We inspect the chase, the firebox, and the damper assembly to determine whether rust has spread beyond the cap. Most 1980s units in Schererville show multiple corroded components by now. Call (888) 289-6055 and we’ll show you exactly what you’re dealing with.
Yes, we can measure and fabricate a chase cover for prefab fireplaces that were built without a cap or where the original was lost years ago. Adding a proper cap stops the direct water intrusion that ruins dampers and rots chase framing. For Schererville homes near Oak Ridge Prairie where wind exposure is higher, we use reinforced attachment and heavier gauge material. The estimate is free, call (888) 289-6055.
Crown coating is a flexible waterproof membrane applied over a structurally sound crown with minor surface cracking, it extends service life 5-10 years at roughly half the cost of replacement. Full crown replacement involves removing the damaged concrete, inspecting the brick beneath, and pouring a new sloped crown with proper overhang and control joints. In Schererville’s freeze-thaw climate, coating is appropriate for early-stage cracking; once the crown is spalling or separating from the brick, replacement is the only lasting fix. We’ll show you photos and give you a straight recommendation.
Yes, we fabricate and install multi-flue cap systems for Schererville homes with multiple flue terminations on a single chase or chimney structure. These are common on larger split-levels with basement fireplaces or homes where the furnace and fireplace share a chase. Proper multi-flue design requires height differentials between flue outlets and adequate separation to prevent downdraft. We measure on-site and fabricate to fit. Call (888) 289-6055 to schedule.
We replaced a rusted-through DuraFlex chase cover on a 1985 split-level off US-30 in the Hawthorne Hills subdivision. The homeowner’s “working fine” fireplace had been channeling lake-effect rain into the chase for years, rotting the adjacent framing. We installed a custom copper cap and sealed the crown flashing, stopping the moisture intrusion that no chimney sweep had caught.
