Why Hearthstone Chimney Co. of Chicago Is Flossmoor’s Preferred Chimney Cap & Crown Company

We’ve worked on chimneys along Sterling Avenue, Western Avenue, and throughout the Flossmoor Country Club corridor for over four decades. The village’s 1950s-1970s brick housing stock is familiar territory. We know which homes have the original combination flues serving both fireplace and furnace, and we know how those oversized clay liners accelerate crown deterioration.

Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your crown is spalled, we’ll show you the spalling. If your cap is rusted through, you’ll see the hole. Then we give you upfront pricing - the number on the estimate is the number on the invoice.

Calls are answered by a live person 24 hours a day, 7 days a week. Not a callback queue. Not an app. A real person who can dispatch a background-checked, uniformed technician to Flossmoor, usually same-day or next-day. Most jobs are completed in a single visit. Done right - and we stand behind it with the 90-Day Done Right Promise in writing, no arguing.

Our Chimney Cap & Crown Services in Flossmoor

Cap Installation

New cap installation on a Flossmoor home starts around $280-$450 for a standard single-flue stainless unit. We see a lot of first-time caps on the pre-WWII homes near the original village core, where chimneys were built without any crown protection at all. Those unprotected flues take the full force of every freeze-thaw cycle off Vollmer Road. A properly sized cap with an animal screen stops water entry, bird nesting, and the leaf debris that Flossmoor’s dense tree canopy drops year-round.

Cap Replacement

Cap replacement in Flossmoor runs $320-$580, with most falling in the mid-range. The old cap comes off, we inspect the crown surface beneath it, and we install a new cap sized to your flue tile. Here’s the local reality: standard galvanized caps on shaded Flossmoor chimneys rust through in 5-7 years. We install stainless or copper caps from Gelco and Olympia Chimney that handle damp, slow-to-warm flue conditions without corroding. On a Flossmoor Country Club-area colonial, we replaced a rusted-through multi-flue cap with a stainless-steel Olympia unit after years of shaded, damp conditions had eaten the original. The homeowner’s self-reliant attitude meant we pre-ordered the cap and completed the job in a single trip, including recoating the spalled crown with a rubberized sealant.

Crown Repair

Crown repair on a Flossmoor mid-century brick chimney typically costs $450-$720. The original crowns on these homes were poured with a sand-cement mix that cracks and flakes after decades of Chicago south-suburb winters - 30 or more freeze-thaw cycles in a typical season. Water gets in, freezes, pops off surface chunks. We cut out the deteriorated material, form a new crown with proper slope and drip edge, and seal it. Combination flues are especially vulnerable because the oversized clay liners create turbulent exhaust flow that deposits acidic soot on crown surfaces, accelerating mortar erosion.

Crown Coating

Crown coating is our most cost-effective option for Flossmoor homeowners with early-stage crown damage: $280-$420. We clean the existing crown, repair minor cracks, and apply a rubberized elastomeric sealant rated for masonry expansion. This buys you years on a crown that’s sound structurally but porous at the surface. For the shaded chimneys common throughout Flossmoor’s wooded neighborhoods, crown coating is often the right middle path - it seals against the prolonged dampness that characterizes these properties without the cost of full replacement.

Multi-Flue Cap

Multi-flue caps cover the entire chimney top, protecting multiple flues and the crown between them. In Flossmoor, where combination flues are the norm rather than the exception, these are frequently the correct solution. Custom-fabricated multi-flue caps run $580-$890 installed. We measure on-site, spec the cap from Olympia Chimney or Famco, and return to install - though most are completed same-day if measurements are straightforward. The single-piece cover eliminates the gap between individual caps where water and debris collect.

Custom Cap

Unusual flue tile sizes, offset flues, or decorative chimney pots require custom fabrication. Custom caps in Flossmoor start around $650 and range upward depending on metal choice and complexity. We template the flue, spec the cap from our fabrication partners, and install with proper clearances and screen mesh. For homeowners in the Flossmoor Country Club area who want copper or aged bronze to match architectural details, we source and install those finishes.

Trusted Brands We Service in Flossmoor

We work exclusively with professional-grade materials - no builder-grade substitutes that fail in three seasons. For cap and crown work in Flossmoor, we stock and install stainless caps from Gelco and Olympia Chimney, crown repair mixes from HeatShield, and elastomeric coatings from Copperfield. These are the brands specified by chimney professionals who plan to warranty their work. We keep common Flossmoor sizes on our trucks, which means faster turnaround and fewer return trips. When a custom or multi-flue cap is needed, we order direct from the manufacturer and coordinate delivery so your job stays on schedule.

Common Chimney Cap & Crown Problems We See in Flossmoor Homes

• Shaded flues cause prolonged condensation under the cap, leading to rust-through on standard galvanized caps within 5-7 years. Flossmoor’s mature tree canopy keeps chimney tops shaded until late morning, suppressing draft and accelerating glazed creosote buildup on caps and crowns - a problem rarely seen in the less-wooded neighboring suburbs. Stainless or copper caps are the fix.
• Over-sized clay liners in combination flues create turbulent exhaust flow that deposits acidic soot on crown surfaces, accelerating mortar erosion. This is the hidden damage pattern in Flossmoor’s 1950s-1970s homes. The crown looks fine from the ground but is being chemically attacked from above.
• Heavy oak and maple branches overhang chimney tops; without properly screened caps, these drop leaves and twigs that plug the flue and trap moisture against the crown. We clear these blockages regularly on the wooded residential streets throughout the village. A cap with 3/4-inch mesh screen prevents it.
• Spalled crown mortar allows water infiltration into the chimney stack, where freeze-thaw cycling destroys brick faces from the inside out. On uninspected Flossmoor chimneys in the 60422 ZIP code, this is the norm, not the exception. Crown coating or repair stops the cycle before rebuild becomes necessary.
