Why Hearthstone Chimney Co. of Chicago Is Mokena’s Preferred Chimney Cap & Crown Company
Our Chimney Cap & Crown team has worked on hundreds of homes in the Lincoln-Way corridor, and Mokena homeowners keep our number because we document what we find. Every inspection ends with photos you can see and a plain-English verdict - no jargon, no scare tactics. We’ve earned strong local reputation in Will County by showing up when we say and standing behind our work with the 90-Day Done Right Promise in writing, no arguing.
Response time to Mokena is typically same-day or next-day for cap and crown issues, especially during the fall rush when homeowners first light their fireplaces and schedule our Fireplace Services in Mokena. We carry replacement chase covers, multi-flue caps, and crown coating materials on our trucks, so most Mokena jobs finish in one visit. Our technicians are background-checked, uniformed, and trained specifically on the prefab fireplace systems that dominate Mokena’s housing stock.
We understand the local building patterns here. When we pull into a Mokena subdivision built between 1985 and 2005, we already know we’re likely looking at a Heatilator, Superior, or Majestic prefab unit with a wood-framed chase and sheet-metal cover. That local knowledge saves time and means we bring the right parts.
Our Chimney Cap & Crown Services in Mokena
Cap Installation
New cap installation in Mokena is almost always for prefab fireplace systems that never had a proper cap, or for homeowners upgrading from a basic builder-grade cover. A correctly sized cap blocks the northwest winds that sweep across Will County’s open terrain, keeping rain, ice, and debris out of your flue. We measure on-site and fabricate custom fits for multi-flue chases, using heavy-gauge materials from Copperfield and Gelco that outlast standard covers.
Cap Replacement
This is our most frequent Chimney Cap & Crown in Mokena service. The sheet-metal chase covers installed on Mokena’s 1985-2005 subdivision homes rust through at seams and corners in 10-15 years, especially in wind-exposed neighborhoods like Fern Lake Estates and Prairie Crossing. We replaced a rusted-through chase cover on a Majestic prefab system off Parker Road in the Estates of Mokena, where the original cover had admitted water for years, rotting the wood chase frame. We installed a heavy-gauge copper multi-flue cap from Copperfield and coated the chase top with Gelco sealant to prevent future corrosion. Cap replacement in Mokena typically runs $280-$480 for standard sizes, with custom copper work ranging higher.
Crown Repair
True masonry crowns are rare in Mokena’s prefab-dominated housing stock, but we do encounter them on older homes near the historic core and on additions that need Chimney Repair in Mokena. When we find cracked or spalling crown concrete, we repair with professional-grade materials and proper slope and overhang to shed water. Most crown repair in Mokena falls in the $350-$550 range, with full rebuilds on larger stacks running higher.
Crown Coating
Crown coating protects existing concrete crowns from freeze-thaw damage, but in Mokena we more often apply this service to the tops of wood-framed chases where the original sealant has failed. The caulk seals between chase cover and chase frame dry out and crack from Will County’s freeze-thaw cycles, letting rain and ice into the enclosure. We strip old sealant, repair any wood damage, and apply flexible crown coating formulated for expansion and contraction. Crown coating in Mokena typically costs $180-$320 and extends the life of your chase structure by years.
Custom Cap
Custom caps solve problems that off-the-shelf covers can’t. In Mokena, we frequently build custom solutions for oversized or oddly configured chases, for multi-flue setups where standard caps don’t seal properly, and for homeowners who want copper or stainless steel that matches their home’s exterior. We fabricate on measurements taken at your Mokena home, not from guesswork. Custom cap work starts around $450 and ranges to $850 or more for complex multi-flue copper installations.
Multi-Flue Cap
Multi-flue caps cover two or more flues with a single protective structure, essential for Mokena homes with fireplace and furnace venting sharing a chase. A properly sized multi-flue cap prevents cross-drafting and ensures each appliance vents safely. We size and install multi-flue caps from Copperfield and Gelco with spark arrestor mesh and proper clearances. Most multi-flue installations in Mokena run $380-$620.

Common Chimney Cap & Crown Problems We See in Mokena Homes
- Sheet-metal chase covers rust through at seams and corners. The factory-built fireplaces in Mokena’s 1985-2005 subdivisions came with galvanized chase covers that simply don’t hold up to 15-20 years of northwest wind exposure. We see this constantly in Fern Lake Estates and Prairie Crossing, where open terrain leaves chimneys fully exposed.
- Caulk seals crack from freeze-thaw cycling. Will County winters stress the flexible sealants between chase cover and wood frame far more than solid masonry would experience. Once the seal fails, water follows the path of least resistance straight into your chase enclosure and onto your firebox.
- Improperly downsized gas-log retrofits leave dangerous venting gaps. Many Mokena homeowners had gas logs installed in the late 1990s and 2000s without resizing the flue to match gas-appliance requirements. The oversized flue opening pulls downdrafts and admits moisture when no cap is present, creating both safety and water-damage issues.
- Missing or damaged spark arrestor mesh. Caps without intact mesh let birds, squirrels, and debris into the flue. In Mokena’s tree-lined subdivisions, this is a recurring problem every spring and fall.

FAQs - Chimney Cap & Crown in Mokena
Most galvanized chase covers on Mokena’s 1985-2005 prefab systems need replacement every 10-15 years, with stainless steel or copper lasting 20-plus years. The northwest wind exposure across Will County’s open terrain accelerates rust at seams and corners, so inspect annually after year 10. Call (888) 289-6055 and we’ll check yours at no charge during a Mokena Chimney Cleaning & Sweep - our $89 special includes full inspection and photos you can see.
Small rust spots can sometimes be addressed with crown coating and sealant, but once rust has penetrated the metal or seams are failing, replacement is the only lasting fix. We’ve patched covers in Mokena only to be called back two seasons later when the rust returned worse. A square deal means telling you when replacement saves money long-term. We’ll show you photos of your cover’s condition and give you both options with exact pricing.
Gas-log retrofits often require smaller flue openings to maintain proper draft and prevent downdrafts, which means the cap must be sized to the reduced flue dimension, not the original opening. Many Mokena homes had gas logs installed in the late 1990s and 2000s without proper flue downsizing, leaving an oversized opening that admits moisture and creates draft problems. We size caps to your actual venting configuration, not your fireplace’s original specs.
A slight surface stain may be cosmetic, but rust stains running down your chase siding almost always indicate seam or corner penetration that will worsen through Will County’s freeze-thaw cycles. We inspect at no charge - if it’s surface-only, we’ll tell you. If water is getting through, we’ll show you exactly where and what replacement costs. Either way, you’ll know where you stand.
Prefab chase covers don’t receive traditional crown coating, but the sealant between cover and wood frame serves the same protective function and needs renewal every 5-8 years in Mokena’s climate. We apply flexible, UV-stable sealant formulated for the temperature swings that crack standard caulk. If your chase top is showing gaps or the cover is lifting, crown coating service for the chase top typically runs $180-$320 and prevents the wood rot that leads to major rebuilds.
