Why Hearthstone Chimney Co. of Chicago Is Westmont’s Preferred Chimney Cap & Crown Company
Westmont homeowners stay with us because we document what we find. Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. In a village where the median home age pushes 60 years, that transparency matters.
We’ve earned strong word-of-mouth in Westmont over four decades. Homeowners near Cass Avenue and in the Gregg Park area call us back because our 90-Day Done Right Promise is in writing with no arguing. If it’s not right, we come back. No paperwork shuffle.
Response time to Westmont averages under an hour. Our technicians are background-checked, uniformed, and carry the parts to finish most jobs in one visit. That matters when your crown is cracked and rain is forecast.
We also understand the local building context. Westmont’s 1955-1975 ranch and bi-level construction used clay-tile flue liners sized for coal-converted or early natural-gas furnaces, not today’s efficient appliances. When we inspect a cap or crown for Chimney Repair in Westmont, we’re checking whether the underlying system can handle what it’s being asked to do now. That’s local knowledge you don’t get from a dispatch operator reading a script.
Our Chimney Cap & Crown Services in Westmont
Cap Installation
New cap installation in Westmont runs $280-$450 for standard galvanized or stainless steel models on a single-flue chimney. For the village’s many double-flue stacks, we typically recommend a multi-flue cap that covers both flues with one integrated unit. Westmont’s mature tree canopy near Ty Warner Park and Veterans Memorial Park means debris and squirrel intrusion are real problems. A properly sized cap with mesh screening stops both. We measure on site, fabricate to fit, and install same-day in most cases.
Cap Replacement
Cap replacement is our most common call in Westmont. The original sheet-metal caps installed in the 1960s and 1970s have rusted through. On a 1960s ranch on Linden Avenue, we found the original clay-tile crown completely spalled from 30 freeze-thaw cycles. The homeowner’s cap was a rusted sheet metal square that had trapped moisture. We installed a custom copper multi-flue cap from Copperfield and tuck-pointed the crown with a crown coating to seal cracks. Replacement caps in Westmont typically cost $320-$580 installed, depending on flue count and access.
Crown Repair
Crown repair addresses the concrete or mortar wash that tops your masonry chimney. In Westmont, crowns built in the 1950s-1970s were often poured too thin or without proper overhang and drip edge. After 25-35 freeze-thaw cycles each winter, they crack and spall. We remove loose material, re-pour with proper slope and thickness, and seal the interface with the flue tile. Crown repair in Westmont ranges from $450-$750 for standard rebuilds. For double-flue crowns where the saddle between flues has failed, we rebuild the entire crown structure.
Crown Coating
Crown coating is a flexible, waterproof membrane we apply over sound but weathered crown concrete. It’s not a fix for structural failure, but for Westmont chimneys with minor cracking and surface deterioration, it’s a cost-effective alternative to full rebuild. Crown coating runs $280-$420 in Westmont and carries a 10-year material warranty. We use professional-grade formulations from HeatShield that remain flexible through our brutal freeze-thaw cycles. The coating buys time on a crown that’s not yet failed, and it prevents the small cracks from becoming the big ones that require rebuild.
Multi-Flue Cap
Multi-flue caps are essential for our Fireplace Services in Westmont, where one flue serves the furnace and another serves the fireplace. A single cap covering both flues eliminates the saddle gap where water pools and freezes. Custom multi-flue caps in Westmont range from $650-$1,200 for stainless steel and $850-$1,400 for copper. We measure your chimney footprint, account for flue height variation, and fabricate a cap that sheds water properly. For Westmont’s 1960s ranch neighborhoods with original steel prefab fireplace inserts inside masonry surrounds, the multi-flue cap also helps manage draft dynamics when both appliances run.
Custom Cap
Custom caps solve problems that off-the-shelf units can’t. Odd flue spacing, oversized footprints, or architectural requirements on Westmont homes near the historic district or custom builds off 55th Street demand fabricated solutions. We work with copper and stainless steel from Copperfield and Olympia Chimney, with custom caps starting at $750 and ranging to $1,600 for complex multi-flue copper designs. Every custom cap is measured, sketched, and approved before fabrication.

Common Chimney Cap & Crown Problems We See in Westmont Homes
- Original clay-tile crowns spalling after decades of freeze-thaw. Westmont’s 25-35 annual freeze-thaw cycles destroy the porous concrete crowns poured in the 1960s. The surface flakes, cracks widen, and water reaches the brick below. Annual inspection catches this before the repair becomes a rebuild.
- Sheet-metal caps from the 1960s rusted through. Common in the Linden Avenue area and throughout Westmont’s ranch neighborhoods. These caps trap moisture against the crown, accelerating decay, and their rusted mesh no longer keeps squirrels out. We’ve pulled nests from flues where the cap was more hole than metal.
- Multi-flue crowns cracking at the saddle between flues. Westmont’s double-flue chimneys, standard in DuPage County tract development, fail at the low point between flue tiles. Water collects, freezes, and splits the crown. Both flues then share the damage. A multi-flue cap and saddle rebuild fixes this permanently.
- Crown overhang missing or inadequate. Original Westmont crowns often lacked the 2-inch overhang and drip edge that protect the brick below. Water runs straight down the chimney face, saturating mortar joints and causing spalling brick. We rebuild with proper overhang as standard practice.

FAQs - Chimney Cap & Crown in Westmont
Yes, a multi-flue cap is the correct solution for your double-flue chimney. Westmont’s 1955-1975 tract homes commonly used one masonry stack to serve both furnace and fireplace, with flues separated by a concrete saddle. Individual caps leave that saddle exposed to water and freeze damage. A multi-flue cap covers the entire crown, sheds water past the brick, and eliminates the gap where squirrels nest. We measure your flue spacing and chimney footprint, then fabricate a cap that fits. Most installations run $650-$1,200 for stainless steel. Call (888) 289-6055 for an exact quote - estimates are free.
Crown coating is a flexible, waterproof membrane applied over a sound but cracked or weathered crown surface. It is not structural repair. For Westmont chimneys with minor surface cracking and intact concrete, crown coating at $280-$420 prevents water intrusion and extends crown life by years. If your crown is spalling, thin, or structurally compromised, coating won’t help and we recommend rebuild. We inspect with a camera to determine which path is appropriate. Call (888) 289-6055 and we’ll give you a plain-English verdict.
No. On Westmont’s 50-70-year-old chimneys, the cap and crown have aged together. A new cap on a failed crown traps moisture and accelerates decay. We’ve removed caps to find the crown beneath completely spalled, with water damage extending to the brick and flue tile. Our inspection includes crown condition, flue tile integrity, and mortar joint assessment. The cap is the last step, not the only step. We document everything with photos you can see. Call (888) 289-6055 for a full inspection - the estimate is free.
A custom copper multi-flue cap for a typical Westmont ranch runs $850-$1,400 installed. Price depends on chimney footprint, flue height variation, and roof access. Copper develops a protective patina and outlasts galvanized steel by decades, which matters on a 60-year-old chimney you plan to maintain rather than rebuild. We measure, sketch, and get your approval before fabricating. Most custom caps install within two weeks of measurement. Call (888) 289-6055 for exact pricing on your chimney.
Westmont’s specific combination of aging housing stock and severe freeze-thaw exposure drives higher crown failure rates. The village’s 1950s-1970s ranches were built with clay-tile crowns sized for coal-to-gas conversion appliances, not modern high-efficiency furnaces. Those crowns were poured thin, without proper overhang, using concrete mixes less resistant to freeze-thaw than today’s standards. Add 25-35 annual freeze-thaw cycles, and the concrete spalls while the clay tile beneath it cracks from thermal shock. Newer suburbs with 1990s construction see this pattern far less. In Westmont, annual inspection isn’t cautious, it’s necessary. Call (888) 289-6055 to schedule yours.
