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

We’ve worked in Naperville long enough to remember when Hobson West was still framed houses and mud lots, providing Naperville Chimney Cleaning & Sweep services since 2014. Forty-two years means we’ve seen which builders cut corners on chimney components, which subdivisions share identical prefab units, and where the masonry chimneys hide behind 1970s brick on the older streets near Naper Boulevard.

Our technicians are background-checked, uniformed, and carry the brands that fit Naperville’s specific housing stock: DuraFlex liners for the masonry chimneys in 60540, Gelco and Olympia Chimney caps sized for the multi-flue setups common near downtown, and HeatShield crown coatings for the hairline cracks that Naperville’s freeze-thaw cycles open every winter. Most jobs finish in one visit. The estimate you sign is the invoice you pay.

Our Chimney Cap & Crown Services in Naperville

Crown Repair

Chimney Repair in Naperville often starts with crown repair, our most common call, and it’s almost always on a 1990s prefab chase with a precast concrete crown that’s cracked after twenty-plus winters of freeze-thaw. The repair isn’t cosmetic. A cracked crown funnels water into the chase, rots the firebox wrapper, and turns a $400 repair into a $2,400 replacement. We recently replaced a cracked concrete crown and installed a custom copper cap on a Heat-N-Glo prefab unit in a Hobson West colonial. The homeowner had complained of water pooling on the hearth-our inspection revealed a hairline crown fracture that had redirected runoff into the chase. We cleaned the crack, applied a bonding agent, and finished with a HeatShield crown coating rated for the temperature swings these units see. Done right, and we stand behind it.

Cap Replacement

Stock galvanized caps from the 1990s subdivision cohorts are rusting through at the seams now. We’ve pulled caps off Ashbury homes where the galvanized steel had perforated so completely that squirrels had nested in the chase. Replacement caps for Naperville’s prefab units run $280-$520 installed, depending on flue count and whether the chase cover needs resealing. For masonry chimneys near downtown, we source Gelco stainless caps with lifetime warranties against rust-through. The old cap comes off, the flue gets inspected while we’re up there, and the new cap gets sealed with high-temp silicone. One visit.

Crown Coating

Crown coating is the preventive move we wish more Naperville homeowners made before the crack widens. We apply HeatShield CrownCoat, a flexible refractory compound that bridges hairline cracks and sheds water while the crown underneath still has structural integrity. At $340-$580 for a typical prefab chase crown, it’s roughly half the cost of a full crown rebuild, and it adds years of service life. We recommend it for any Naperville home with a crown showing map cracking but no spalling or separation from the chase walls. Our Level-2 camera inspection documents the condition with photos you can see and a plain-English verdict on whether coating will hold or if we’re past that point.

Multi-Flue Cap Installation

Multi-flue caps cover two or more flues with a single hood, and they’re the right choice for most Naperville masonry chimneys that vent a fireplace and a furnace or water heater, which is why our Fireplace Services in Naperville include proper cap sizing and installation. The caps we install from Olympia Chimney sit high enough to let each flue draft properly while keeping rain and animals out. Poorly fitted multi-flue caps sit too low, trap moisture against the crown, and accelerate the spalling we see on 60540 chimneys every spring. We measure each flue position, specify the correct cap height, and seal the mounting points with refractory mortar. Typical installed cost: $680-$1,240.

Custom Cap Fabrication

Custom copper caps are what we recommend for older masonry chimneys near downtown Naperville, especially the 1950s-1970s brick colonials where standard sizes don’t fit or where the homeowner wants a cap that matches the architectural detail. We measure on-site, fabricate to the flue configuration, and install with soldered seams and brass fasteners that won’t corrode. A custom copper cap runs $1,200-$1,850 installed, and it’ll outlast the house. We also fabricate black galvanized or stainless custom caps for homeowners who want the fit without the copper premium.

Trusted Brands We Service in Naperville

We don’t use builder-grade substitutes. For Naperville’s mix of prefab and masonry chimneys, we stock DuraFlex liner components for chase relining, HeatShield crown and flue coatings for crack repair and resurfacing, and Gelco and Olympia Chimney caps in the sizes that fit local housing stock. Having the right parts on the truck means most Naperville jobs finish in a single visit. No waiting two weeks for a special-order cap that doesn’t quite fit. No improvising with hardware-store aluminum that’ll be rusted through in three winters.

Common Chimney Cap & Crown Problems We See in Naperville Homes

• Hairline crown cracks on 1990s prefab chases. Builder-grade precast crowns on Naperville’s subdivision fireplaces develop fractures after repeated freeze-thaw cycling. Water enters, freezes, widens the crack, and eventually rots the firebox wrapper. We catch these with camera inspection before the damage spreads.
• Rusted-through stock caps in Ashbury and Hobson West. The galvanized caps installed by original builders in these subdivisions are hitting 25-30 years of service. Seams corrode, mesh screens detach, and the flue becomes an open door for rain, leaves, and raccoons.
• Low-sitting multi-flue caps trapping moisture on 60540 masonry. Older Naperville homes near downtown often have multi-flue caps installed too close to the flue tiles. Condensation collects, freezes overnight, and spalls the crown surface by spring. We raise or replace with properly spec’d caps.
• Chase cover separation on Route 59 corridor prefabs. The metal chase tops on 1980s-1990s zero-clearance units pull away from the framing as caulking ages. Water runs down the chase interior, stains the fireplace surround, and rusts the damper mechanism. Crown repair plus new cap usually solves it.
