Our Chimney Cap & Crown Services in Frankfort
Cap Installation
New cap installation in Frankfort runs $340-$620 for standard single-flue models, $580-$940 for multi-flue systems. On the prefabricated fireplaces common in Prestwick and the surrounding golf communities, we often see caps that were selected for roof-line aesthetics rather than functional protection. A cap that looks right but lets wind-driven rain into the chase is worse than no cap at all. We measure your flue or chase top, account for Frankfort’s exposure to northwest winter winds, and install a cap that actually sheds water and debris. Most installations take under two hours.

Cap Replacement
Cap replacement in Frankfort typically costs $280-$520. The custom copper caps original to many 2000s-era prefab fireplaces in Frankfort’s upscale subdivisions are a particular specialty of ours. Those caps corrode prematurely from acidic wood smoke condensation - the copper looks fine from the ground, but pinholes develop underneath where you can’t see. We recently serviced a home on Lakeview Drive in Prestwick where a custom copper cap, original to the circa-2002 prefab fireplace, had developed pinhole leaks from freeze-thaw cycling. The chase interior showed rust staining, and we replaced the cap with a Famco multi-flue heavy-duty model, properly sealing the crown with Gelco coating to prevent further moisture intrusion.

Crown Repair
Crown repair on Frankfort’s historic masonry chimneys, particularly the legacy brickwork near Kansas Street downtown, runs $420-$780. Decades of aggressive freeze-thaw cycling in Will County spall the concrete crown surface and open mortar joints. Old paint layers often hide the damage until a Level-2 camera inspection reveals the truth. We remove deteriorated material, reform the crown with proper slope and drip edge, and seal with professional-grade compounds. Done right, a rebuilt crown should outlast the next generation of owners.

Crown Coating
Crown coating is our most cost-effective preventive service for Frankfort homeowners: $280-$450 for most chimneys. We apply Gelco CrownSeal, a flexible waterproof membrane that bridges hairline cracks and stops water penetration before freeze-thaw can open them wider. For the masonry chimneys in Frankfort’s older neighborhoods, this is often the difference between a $400 coating and a $2,000+ rebuild five years later. We recommend crown coating every 8-10 years in Frankfort’s climate, sooner if you see efflorescence or flaking on the crown surface.

Multi-Flue Cap
Multi-flue caps for Frankfort’s larger custom homes, particularly in the golf-course communities, range from $620-$1,180 installed. These systems cover multiple flues or an entire chase top with a single protective shell. We fabricate and install multi-flue caps with proper clearance, ventilation, and wind resistance for Frankfort’s open terrain. Improperly sealed multi-flue crowns on newer custom homes allow water to wick into the chase, causing metal firebox rust and flue liner degradation undetected for years. Our installations use Famco and Olympia Chimney components with welded seams and stainless-steel construction.

Custom Cap
Custom caps for Frankfort’s architecturally distinctive homes - matching copper gutters, specific roof pitches, HOA requirements in Prestwick or similar communities - run $740-$1,340. We fabricate to specification using professional-grade materials, not builder-grade substitutes. If your original custom cap has failed, we can replicate the look with functional improvements: heavier gauge metal, better internal bracing, and proper sealant integration with the crown. Photos of your existing cap and a quick field measurement get us started.

Common Chimney Cap & Crown Problems We See in Frankfort Homes
- Custom copper caps on Prestwick-area homes corrode prematurely from acidic wood smoke condensation, requiring replacement before the 20-year prefab fireplace itself wears out. The copper develops pinholes underneath where inspection from the ground won’t catch them.
- Legacy masonry crowns on Kansas Street historic homes spall due to decades of aggressive freeze-thaw, often hidden by old paint layers until chimney sweeps inspect. We find this almost every winter on calls from the historic core.
- Improperly sealed multi-flue crowns on newer custom homes allow water to wick into the chase, causing metal firebox rust and flue liner degradation undetected for years. The fireplace still “works” - until it doesn’t, and the repair becomes a full system replacement.
- Decorative caps installed without functional wind or rain protection on 1990s-2000s prefab systems in Frankfort’s golf-course subdivisions. They matched the roof line beautifully. They just didn’t keep water out.

Custom fabrication adds material and shop time.

No surprises on the bill. Estimates are free. Call (888) 289-6055.

FAQs - Chimney Cap & Crown in Frankfort
Yes. The cap’s condition is independent of whether the fireplace lights. In Prestwick and similar Frankfort golf communities, we regularly find decorative copper caps that have developed pinhole corrosion while the fireplace still operates. Water enters the chase, rusts the metal firebox, and degrades the flue liner - all hidden from view until failure. We recommend annual inspection with photo documentation. Call (888) 289-6055 for a free estimate.
Look for efflorescence (white mineral staining) on the brick below the crown, pieces of concrete on the ground, or interior water stains near the chimney breast. On Frankfort’s historic masonry chimneys, decades of freeze-thaw cycling spall the crown surface, and old paint often conceals the damage. A Level-2 camera inspection with photos reveals what the eye cannot. If you’re unsure, we’ll inspect and show you exactly what we find - no charge for the estimate.
We can. Custom cap fabrication runs $740-$1,340 in Frankfort, and we replicate existing profiles while upgrading the functional protection. We use heavier gauge material and proper internal bracing so the new cap outperforms the original. Bring us photos of your current cap and gutter line, or we’ll measure in person. Most custom jobs finish in two weeks from measurement to installation.
Yes. Infrequent use does not protect against Frankfort’s primary threat: moisture intrusion from rain, snow, and freeze-thaw cycling. In fact, occasional fires produce more acidic condensation in a cold flue than regular use, accelerating cap corrosion. We recommend inspection every 12 months regardless of burn frequency, with crown coating every 8-10 years for masonry chimneys. The $89 seasonal tune-up covers cap condition, crown assessment, and basic cleaning.
We install Famco multi-flue caps and Gelco coating systems for prefab chases, with Olympia Chimney components for specialized applications. These are professional-grade materials, not builder-grade substitutes, rated for the thermal cycling and wind exposure specific to northern Illinois. We stock the common sizes on our trucks for same-day completion. Call (888) 289-6055 and we’ll confirm fit for your specific chase dimensions.
