Why Hearthstone Chimney Co. of Chicago Is Clarendon Hills’s Preferred Chimney Cap & Crown Company
We’ve been working on Clarendon Hills chimneys since the early 1980s, back when many of these homes were hitting their first major maintenance cycle. The village’s uniform mid-century housing stock means our technicians have replaced and repaired thousands of virtually identical chimney systems - we know what fails, where it fails, and how to fix it without exploratory demolition.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. Homeowners in the 55-75 range, many of whom have been burned by contractors before, tell us this transparency is why they call us back for their liner work.
Calls are answered by a live person 24 hours a day, 7 days a week - not a voicemail, not a callback queue. Our background-checked, uniformed technicians carry professional-grade materials from Copperfield, Gelco, and Olympia Chimney on every truck. Most jobs finish in one visit, with no-hassle upfront pricing: the number on the estimate is the number on the invoice.
Every repair is backed by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we make it right. We’ve operated this way for over 42 years, and we plan to be here for 30 more.
Our Chimney Cap & Crown Services in Clarendon Hills
Custom Cap Installation
Mid-century chimneys in the area were built with standard single-flue caps that rust through after 50-70 years of DuPage County weather - regular Clarendon Hills Chimney Cleaning & Sweep visits help spot this before it worsens. We fabricate and install custom caps sized to your exact flue configuration, including multi-flue setups where original clay tiles have spalled or shifted. A proper custom cap seals against water, debris, and animals while allowing proper draft - critical on these aging systems where liner failure has already compromised airflow.
Multi-Flue Cap Replacement
Many Clarendon Hills homeowners inherit incompatible multi-flue caps from previous owners, installed hastily over deteriorating single-flue systems. These trap moisture against already-compromised clay tiles, accelerating the freeze-thaw damage that defines local chimney failure. We remove these mismatched caps and install correctly sized multi-flue units from Copperfield or Gelco, engineered to vent properly while protecting the crown below.
Crown Repair
The concrete crown atop your chimney is not decorative - it’s the primary water barrier between your flue and the structure below. On a 1965 ranch near the Burlington Northern tracks, we replaced a rusted-through multi-flue cap with a heavy-duty Fabricated Copperfield cap to seal three flues where original clay tiles had spalled from freeze-thaw. The homeowner, a self-reliant third owner, had noticed water stains inside the firebox after heavy rain - the old crown had cracked mortar joints from repeated cycling. We coated the newly rebuilt crown with Crown Coat and installed the custom cap, guaranteeing one-trip completion.
Crown Coating
Crown Coat is a flexible, waterproof membrane we apply to rebuilt or sound existing crowns. In Clarendon Hills, where 30+ freeze-thaw cycles per winter attack concrete crowns with hairline cracks invisible from ground level, this coating is not optional - it’s what keeps water out of your liner system for the next decade. We use professional-grade Crown Coat from HeatShield, applied to a properly prepared surface, not painted over active deterioration.

For Clarendon Hills’s demanding climate, we stock DuraFlex liner components, HeatShield crown coating and refractory products, and caps from Gelco and Olympia Chimney. Copperfield fabricated caps are our go-to for custom multi-flue installations on these aging mid-century systems. These are the same brands specified by chimney engineers for freeze-thaw environments; we keep them on our trucks so your repair doesn’t wait on a parts order.
Common Chimney Cap & Crown Problems We See in Clarendon Hills Homes
- Crowns on 50-70-year-old clay tile chimneys develop hairline cracks from 30+ freeze-thaw cycles per winter, invisible from ground level but allowing water penetration that accelerates liner failure. We find these with our Level-2 camera inspection, document them with photos, and rebuild or coat before the next freeze.
- Original single-flue caps rust through after decades of exposure, often replaced with incompatible multi-flue caps that trap moisture against deteriorating clay tiles. The correct fix is a properly sized cap paired with crown assessment - not another generic replacement.
- Missing or undersized caps on detached workshops and outbuildings allow debris and animals into flues, compounding drafting issues from undisclosed historic liner problems. These structures need heavy-duty caps rated for exposed installation, not the lightweight units sold at hardware stores.
- Homeowners who bought their 1960s ranch in the last decade frequently discover fractured clay flue tiles - the previous long-term owners stopped using the fireplace years ago because of drafting problems caused by liner failure, but that history was never disclosed at sale. The cap and crown look fine from outside; the damage is internal and progressive.

FAQs - Chimney Cap & Crown in Clarendon Hills
You likely need a custom or multi-flue cap, because original single-flue caps on these aging systems rarely seal properly once tiles have spalled or shifted from decades of freeze-thaw. We assess your flue condition with a camera inspection before recommending cap size - a standard cap forced onto a damaged liner will leak and fail prematurely. Call (888) 289-6055 to schedule; estimates are free.
DuPage County experiences 30 or more freeze-thaw cycles each winter, and the concrete crowns on 50-70-year-old chimneys absorb moisture through hairline cracks that expand when frozen, widening each cycle. This is nearly universal in Clarendon Hills’s age-homogeneous housing stock, and invisible from ground level until water stains appear inside. Crown Coat applied after proper repair creates a flexible waterproof barrier that moves with the concrete instead of cracking again.
The crown is likely a contributing factor, but the root cause is probably fractured clay flue tiles from decades of thermal stress and freeze-thaw damage - a pattern we see constantly in Clarendon Hills’s mid-century stock. Water entering through crown cracks accelerates liner deterioration, which causes drafting failure, which leads owners to abandon the fireplace. We diagnose this with Chimney Repair - Clarendon Hills expertise and a Level-2 camera inspection that shows you exactly what failed and why. Call (888) 289-6055 for a free second opinion on any written estimate.
Yes - we install heavy-duty fabricated caps rated for exposed structures, sized to your flue count and dimensions, not the lightweight universal caps sold retail. Workshop chimneys in Clarendon Hills face the same freeze-thaw exposure as main-house systems, often with less maintenance history. We stock custom-fabrication materials for same-day completion on most jobs.
In Clarendon Hills, yes - crown coating is necessary even with a good cap, because no cap seals perfectly against wind-driven rain, and your 50-70-year-old crown already has micro-cracks from decades of freeze-thaw. Crown Coat from HeatShield bridges those cracks and creates a waterproof membrane that protects the concrete itself. We apply it to every crown we repair or rebuild; skipping it would mean returning in two or three years to do the job again. That’s not how we work.
