We’ve worked on Prospect Heights chimneys for decades. The housing stock here is specific: late-1960s through 1980s ranches and split-levels, most with original masonry fireplaces that have never been relined. That matters because a crown that was adequate in 1975 is often crumbling now, and a cap that fit a single flue may be completely wrong for a dual-flue configuration. Our Chimney Cap & Crown team knows what to look for.

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

We’ve been answering calls with a live person for over 42 years, and Prospect Heights homeowners have been among them since the 1980s. The city sits just outside Chicago’s urban heat island, which means your chimney crown endures harder freeze-thaw cycles than chimneys in Lincoln Park or the Loop. We account for that in our material choices and our inspection schedule.

Our technicians are background-checked and uniformed, and they complete most jobs in a single visit. We document every inspection with photos and a plain-English verdict - you’ll see what we see, and you’ll understand what needs to happen and why. No arguing, no paperwork games: our 90-Day Done Right Promise is in writing, and if something isn’t right, we come back.

We know the streets here. North Elm, where we replaced a failed crown on a 1970s split-level last fall. Palatine Road, with its mix of ranches and townhomes. The neighborhoods near Willow Road, where alley-load access means we bring the right equipment the first time. We’re not learning Prospect Heights on your dime.

Our no-hassle upfront pricing means the number on the estimate is the number on the invoice. We’ve heard from too many homeowners who got a low opening bid that ballooned once the crew was on the roof. That doesn’t happen here.

Our Chimney Cap & Crown Services in Prospect Heights

Cap Installation

New cap installation in Prospect Heights typically costs $280-$520 for a standard single-flue galvanized or stainless steel cap, and $480-$780 for a custom multi-flue cap on a dual-flue chimney. Most homes in Prospect Heights were built with single flues venting both the fireplace and the furnace, which is a configuration that requires careful sizing. A cap that doesn’t cover both flues completely, or that lacks proper mesh screening, will let debris, squirrels, and water into the system. We size every cap to the specific flue arrangement on your roof, and we use only professional-grade materials from brands like Gelco and Copperfield - no builder-grade substitutes that rust through in three winters.

Cap Replacement

If your existing cap is rusted, blown off in a windstorm, or was never the right size to begin with, replacement is straightforward but critical. In Prospect Heights, we see a lot of original caps that were installed in the 1980s and have simply reached the end of their service life. We also see caps that were replaced by handymen using hardware-store sizes that don’t actually cover the flue properly. A cap replacement from Hearthstone includes removal and disposal of the old unit, inspection of the flue top and crown surface beneath it, and installation of a properly sized replacement. Most cap replacements in Prospect Heights are done in under two hours.

Crown Repair

Crown repair is where Prospect Heights’s housing age really shows. A typical crown repair runs $420-$680 for crack sealing and resurfacing with a professional-grade crown coating, or $780-$1,340 if the crown has spalled badly enough to require partial rebuild. The crowns on 1960s and 1970s ranch homes here were often poured with too little slope or too thin a layer of concrete, and 45-60 years of Cook County freeze-thaw cycles have taken their toll. Spring inspections in Prospect Heights routinely reveal new cracking that wasn’t there the previous fall. We use HeatShield crown resurfacing products where appropriate, or we form and pour a new concrete crown with proper drip edges and slope to shed water away from the masonry.

Crown Coating

For crowns that are structurally sound but showing early surface cracking, a crown coating can add 10-15 years of service life at a fraction of replacement cost. Crown coating in Prospect Heights typically runs $340-$520. We use flexible, breathable coatings that can move slightly with the masonry during freeze-thaw cycles without delaminating. This is particularly valuable in Prospect Heights, where the lack of urban heat-island buffering means more extreme temperature swings than chimneys experience closer to downtown. We won’t sell you a coating if the crown is too far gone - we’ll show you the photos and explain why.

Multi-Flue Cap

Multi-flue caps are essential for many Prospect Heights homes. The defining local configuration is a single chimney structure with two flues - one for the wood-burning fireplace, one for the gas furnace - and a cap that covers both with a single hood and proper mesh screening. Multi-flue cap installation in Prospect Heights runs $480-$890 depending on size and material. We fabricate custom sizes when needed, and we always verify that each flue has adequate draft clearance under the new cap. A poorly designed multi-flue cap can cause one flue to backdraft into the other, which is a serious safety issue we check for during installation.

Custom Cap

When standard sizes won’t work - unusual flue spacing, ornate chimney pots, or specific HOA requirements in Prospect Heights subdivisions - we fabricate custom caps from copper, stainless steel, or black galvanized steel. Custom caps start around $680 and can range to $1,200+ for elaborate copper work. Last fall we replaced a crown cap on a 1970s split-level on North Elm Street. The old crown had spalled from freeze-thaw cycles, and debris had fallen into the dual flue (fireplace + furnace). We installed a custom multi-flue copper cap from Copperfield to vent both flues securely. The homeowner still has the photos we sent from the roof.

Trusted Brands We Service in Prospect Heights

We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. For Prospect Heights homeowners, this means we stock common cap sizes and crown repair materials locally, so we’re not ordering parts and making you wait. A Gelco stainless cap or Copperfield multi-flue unit can usually be on your roof within days, not weeks. We don’t use builder-grade substitutes from big-box stores - the difference shows up in year five, when a cheap cap has rusted through and you’re paying for the job again.

Common Chimney Cap & Crown Problems We See in Prospect Heights Homes

• Crowns spalling from freeze-thaw damage. Prospect Heights sees 20-30 freeze-thaw cycles per winter without Chicago’s urban heat-island buffer, and the concrete crowns on 1960s-70s ranch homes were rarely built to withstand them. By spring, the surface is flaking and cracks have widened enough to let water reach the flue liner below.
• Dual-flue chimneys with failed cap seals. Split-level homes throughout Prospect Heights route fireplace and furnace flues through a single chimney structure. When the cap seal fails or the cap is missing, debris falls into both flues, and creosote from the fireplace can contaminate the furnace flue path. Each flue requires separate inspection.
• Hidden water damage in interior floor cavities. Split-level construction in Prospect Heights frequently runs chimney flues through floor cavities before they exit the roofline. When crown cracks or flashing failures let water in, it travels down these hidden sections and damages framing long before any stain appears on the ceiling. A Level-2 camera inspection finds this.
• Original clay tile liners cracking and spalling. Most Prospect Heights masonry chimneys are now 45-60+ years old, the exact age range at which original clay tile flue liners begin to fail. A cracked liner combined with a failed crown is a fire hazard and a carbon monoxide risk. We check liner condition during every cap and crown evaluation.
