Fast, Reliable Chimney Cap & Crown Across Frankfort Square
Chimney cap and crown repair in Frankfort Square typically runs $280-$650 for most jobs, and our technicians can usually be on your street within the same day you call.

Our Chimney Cap & Crown Services in Frankfort Square
Cap Replacement
Cap replacement is our most frequent call in Frankfort Square, and there’s a reason. The galvanized or aluminum caps installed on prefab chimneys in the 1980s and 1990s were never meant to survive 25-40 years of Will County freeze-thaw cycling. We’ve replaced hundreds. A typical cap replacement in Frankfort Square runs $280-$420 for a standard single-flue stainless steel unit, including removal of the corroded original and proper sealing. On a cold November morning in the Hickory Creek Estates subdivision, we replaced the rusted-through multi-flue cap on a 1989 Preway prefab fireplace - the seventh identical repair on the same block. The original builder-grade cap had corroded from freeze-thaw cycling, and we installed a heavy-gauge stainless steel replacement with a DuraFlex liner adapter to match the 8-inch flue diameter.
Multi-Flue Cap Installation
Some Frankfort Square homes, particularly the larger two-story colonials built in the early 1990s, have multiple flues sharing a single chase - one for the fireplace, one for the furnace or water heater. A multi-flue cap covers the entire chase top with a single hooded unit, keeping rain and animals out of all flues at once. These run $450-$650 installed in Frankfort Square, depending on chase dimensions and whether the existing chase cover requires reframing. We fabricate to fit; no builder-grade substitutes.
Crown Repair
The crown is the concrete or mortar slab that tops a masonry chimney, but in Frankfort Square’s prefab-dominant housing stock, we more often encounter “crowns” formed from the chase cover itself or from a thin mortar wash over a metal frame. Either way, cracks let water in, and water in a prefab chase destroys the firebox from above. Crown repair here means removing the failed surface, rebuilding with proper slope and overhang, and sealing with a flexible crown coating rated for our temperature swings. Typical crown repair in Frankfort Square: $380-$550.
Crown Coating
For crowns with minor cracking that hasn’t yet compromised the chase structure, we apply a specialized flexible coating - we use HeatShield or Gelco formulations depending on the substrate - that bridges hairline cracks and sheds water. This is preventive maintenance, not a fix for advanced failure. In Frankfort Square’s climate, with sustained sub-zero cold snaps and aggressive freeze-thaw each winter, a coated crown lasts longer than an untreated one, but only if the underlying structure is sound. Crown coating runs $180-$290 here. We’ll tell you honestly if your crown is past coating and needs rebuild.

Trusted Brands We Service in Frankfort Square
We stock parts and specify materials from Copperfield, DuraFlex, and Gelco - brands that hold up in Will County weather, not hardware-store substitutes that corrode in three seasons. For Frankfort Square’s prefab-heavy housing stock, this matters because the wrong cap or liner adapter won’t seat properly on a factory-built flue, and an improper seal invites the moisture problems you’re trying to prevent. Our technicians carry common cap sizes and crown repair materials on the truck, so most Frankfort Square jobs finish in a single visit. No waiting on parts, no return trip, no surprises on the bill.
Common Chimney Cap & Crown Problems We See in Frankfort Square Homes
- Factory-built chase covers corrode in Will County’s freeze-thaw cycles. The galvanized steel or thin aluminum covers on 1980s-1990s prefab chimneys weren’t designed for decades of expansion and contraction. Once the protective coating cracks, rust spreads fast, and water reaches the firebox below.
- Builder-grade mortar caps on prefab zero-clearance chimneys crack within 25-40 years. Many Frankfort Square homes are right in that window now. A cracked cap doesn’t just leak; it lets combustion gases escape into the chase wall, accelerating deterioration of every component downstream.
- Galvanized multi-flue caps rust through at the seams. Common in 1980s-1990s Frankfort Square subdivisions. The seam is the weak point, and once water penetrates, the cap becomes a funnel instead of a shield.
- Missing or improperly sized caps from original construction. Some builders in the Will County expansion cut corners, installing caps that don’t fully cover the flue or omitting them entirely on secondary flues. We’ve found uncapped furnace flues in Frankfort Square homes where birds had nested for years.

What moves the number? Chase height and roof access affect labor time. The condition of the existing chase cover or crown determines whether we’re removing and replacing or building from stripped metal. And the specific prefab model matters - some 1980s units used proprietary flue diameters that require adapter fabrication. We give you the full price before we start. The number on the estimate is the number on the invoice.

FAQs - Chimney Cap & Crown in Frankfort Square
The original caps were builder-grade galvanized steel or thin aluminum, installed during an era when prefab fireplaces were treated as disposable appliances with 15-20 year lifespans. Will County’s sustained sub-zero cold snaps and aggressive freeze-thaw cycling corrode these metals far faster than the builders anticipated. Most Frankfort Square homes in this vintage are now 25-40 years old, squarely in the failure window. Call (888) 289-6055 for a free inspection - estimates are free.
A multi-flue cap is a single hooded unit that covers two or more flues protruding from the same chase, common in larger 1990s colonials here. If your home has both a fireplace flue and a furnace or water heater flue sharing a chase, you need one. It keeps rain and animals out of all flues simultaneously and prevents cross-contamination of combustion gases. Most multi-flue cap installations in Frankfort Square run $450-$650. Call (888) 289-6055 and we’ll measure your chase on the spot.
Yes, we apply a flexible crown coating as the final step of every crown repair, and it is particularly worth it in Frankfort Square’s climate. Will County’s freeze-thaw cycling works water into microscopic cracks, then expands that water into ice that fractures the crown from within. A proper coating sheds water and flexes with temperature swings, extending the repair’s life by years. Crown coating alone runs $180-$290; combined with repair, it’s built into the $380-$550 range. Call (888) 289-6055 to schedule.
Yes. These are among the most common prefab units we encounter in Frankfort Square subdivisions, and we stock or fabricate the adapters and caps that fit their 8-inch and 10-inch flue diameters. Preway and Heatilator chase covers and caps fail predictably in this area; we’ve replaced enough to know the part numbers by sight. Typical replacement: $280-$420. Call (888) 289-6055 - we can usually identify your unit from a photo if you’re unsure of the model.
Not necessarily, but you should have it inspected if your home is 25 years or older. Some caps fail from the underside first - corrosion where combustion moisture collects - while the top still looks presentable. And a cap can be intact but improperly sized, leaving gaps that admit water or animals. Our Level-2 camera inspection includes photos of the cap and crown from above; you’ll see what we see. Inspections run $89 during our seasonal tune-up special. Call (888) 289-6055 to book.
