Why Hearthstone Chimney Co. of Chicago Is Des Plaines’s Preferred Chimney Cap & Crown Company
We’ve been driving to Des Plaines since 2014, back when the tollway was still I-90 and most of these chimneys were only twenty years old. Now they’re fifty to seventy-five years old, and we know what that means for mortar, crowns, and flue sizing in this specific market.
Our technicians are background-checked and uniformed, and they arrive with professional-grade materials from Olympia Chimney, DuraFlex, and Gelco already on the truck. Most Des Plaines jobs finish in one visit because we’ve seen the patterns before - the abandoned furnace flues, the vibration cracks, the river-corridor moisture wicking up from the base. We document every inspection with photos you can see and a plain-English verdict. No jargon, no scare tactics.
The 90-Day Done Right Promise governs every job: Krafted right, Every time, Your home first, Standing behind it. In writing, no arguing. If it’s not right, we come back. That’s been our standard for over 42 years, and it’s why Des Plaines homeowners who’ve been burned by contractors before tend to stick with us.
Our Chimney Cap & Crown Services in Des Plaines
Custom Cap Installation
Stock caps from the hardware store don’t fit the reality of many Des Plaines homes. In the east-side neighborhood off Oakton, a homeowner with a 1960s combination chimney - abandoned furnace flue, now oversized for fireplace only - had chronic downdraft and heavy creosote condensation. We installed a custom Olympia multi-flue cap to seal the unused opening, sized a DuraFlex liner to match fireplace output, and tuckpointed the crown using a flexible coating to resist freeze-thaw and vibration. Custom caps are fabricated to your flue count, your roof pitch, and your exposure to ice load. Typical custom cap installation in Des Plaines runs $450-$780.

Cap Replacement
When the existing cap is rusted through, wind-damaged, or simply the wrong size for a converted flue, replacement is straightforward if you measure correctly. We don’t. We come to your home in Des Plaines - whether you’re off Golf Road, near Algonquin and Wolf, or back in the 60018 zip - and measure on-site. Most replacements use Gelco or Famco galvanized or stainless steel caps with proper screening to keep out raccoons and squirrels, both of which are active along the Des Plaines River corridor. Standard cap replacement in Des Plaines is usually $280-$420 installed.

Crown Repair
The concrete crown at the top of your chimney is the first line of defense against water intrusion. In Des Plaines, it’s also the first casualty of O’Hare’s constant jet vibration. We’ve rebuilt crowns on homes near Touhy and River, near Central and Lee, and throughout the 60016 zip where the flight path noise is a daily fact of life. Crown repair involves removing loose material, forming a proper slope for drainage, and pouring new concrete or applying a specialized crown coating. Crown repair in Des Plaines typically costs $380-$650.

Crown Coating
For crowns with minor cracking that hasn’t yet compromised the structural slab, a flexible crown coating can add years of service without full rebuild. This is particularly valuable in Des Plaines, where the freeze-thaw cycle is severe and the Des Plaines River corridor adds localized ground moisture that wicks into chimney bases. We use professional-grade flexible coatings - not the bucket-grade sealers from the big-box store - that move with the masonry as it expands and contracts. Crown coating in Des Plaines runs $320-$480 and is often paired with cap replacement for a complete weatherproofing system.

Multi-Flue Cap
Homes with multiple fireplaces or combination chimneys need multi-flue caps that cover the entire chimney top with proper clearance and independent screening for each flue. This is essential for the many 1960s-70s Des Plaines homes built with combination chimneys serving both gas furnace and fireplace. After furnace upgrades to high-efficiency sidewall venting, the abandoned flue creates draft problems that a standard single-flue cap worsens. Multi-flue caps in Des Plaines range from $520-$890 depending on size and material.

Trusted Brands We Service in Des Plaines
We work exclusively with professional-grade materials - no builder-grade substitutes that fail in year three. For Des Plaines homes, we stock Olympia Chimney multi-flue caps, DuraFlex flexible liners, and Gelco custom-fabricated caps on our service vehicles. This means when we’re called to a home off Rand Road or near Maine East, we don’t order parts and return in two weeks. We measure, fabricate if needed, and install. The brands we use - HeatShield for crown coatings, Famco for standard replacements - are the same ones specified by chimney professionals nationwide because they survive Midwest winters and, in Des Plaines’s case, the added stress of airport-adjacent vibration.
Common Chimney Cap & Crown Problems We See in Des Plaines Homes
- Crown cracking from O’Hare vibration. The constant low-frequency rumble from jet aircraft accelerates mortar joint deterioration in brick masonry chimneys. A crown that might last decades in Park Ridge or Niles can show accelerated spalling and loose joints here, letting water into the chimney stack and accelerating freeze-thaw damage.
- Oversized flue openings from abandoned furnace vents. Many Des Plaines homeowners upgraded to high-efficiency furnaces venting through PVC sidewall pipes, leaving the original furnace flue abandoned. The chimney is now oversized for fireplace-only use, causing chronic downdraft, heavy creosote condensation, and liner deterioration - problems a standard cap can’t fix.
- Stock caps too light for heavy ice buildup. Des Plaines acreage properties and homes with exposed rooflines see significant ice accumulation. Lightweight hardware-store caps dent, dislodge, or tear off. Heavy-duty custom caps with reinforced mounting are necessary for properties near the river corridor or on larger lots with unobstructed wind exposure.
- River-corridor moisture wicking into chimney bases. The Des Plaines River and its tributaries create localized soil moisture conditions that differ from drier suburbs to the west. This moisture travels up through the masonry and exploits any micro-cracks in aging mortar, making crown integrity even more critical for long-term chimney health.

FAQs - Chimney Cap & Crown in Des Plaines
Des Plaines chimneys need more frequent crown repair because constant low-frequency vibration from O’Hare International Airport accelerates mortar joint deterioration and micro-cracking in concrete crowns. This vibration, combined with the severe Chicago freeze-thaw cycle and river-corridor moisture, creates a failure rate we don’t see at the same pace in Park Ridge or Mount Prospect. Annual inspection is more critical here than in quieter suburbs. Call (888) 289-6055 to schedule - estimates are free.
An oversized flue causes chronic downdraft and poor draft because the volume of air moving through the fireplace cannot properly fill the now-oversized chimney chamber. A standard single-flue cap makes this worse by trapping cold air and forcing smoke back into the home. We typically recommend a custom multi-flue cap that seals the abandoned flue opening while properly sizing the active fireplace flue, often paired with a DuraFlex liner to restore correct draft dynamics. Call (888) 289-6055 and we’ll assess your specific flue configuration.
Heavy-gauge stainless steel or copper custom caps with reinforced mounting brackets and extended skirt coverage work best for properties with significant ice and snow load. Standard galvanized caps dent and dislodge. We fabricate custom caps with proper slope and structural ribs that shed ice rather than collecting it, using materials from Gelco or Olympia Chimney rated for extreme weather exposure. For Des Plaines acreage lots near the river or on exposed ridges, this is not the place to save money. Call (888) 289-6055 for a measurement and exact quote.
Yes, we carry extended ladders, roof-access equipment, and safety rigging for steep-pitch or multi-story chimneys common on larger Des Plaines properties. Our technicians are trained for height work and arrive prepared so we don’t need a second trip. Most jobs are completed in a single visit, including those on tall chimneys serving walkout basements or second-floor fireplaces. Call (888) 289-6055 to discuss access - we’ll confirm we can handle it before we dispatch.
The Des Plaines River corridor creates localized soil moisture that wicks upward through masonry chimney bases, keeping the lower chimney structure damper than in suburbs with better drainage. This moisture migrates upward and exploits any micro-cracks in the crown, accelerating freeze-thaw spalling from the inside out. A properly sealed crown with flexible coating and correct overhang is essential to interrupt this moisture path and protect the chimney structure. Call (888) 289-6055 for an inspection - we’ll document crown condition with photos you can see.
