We’ve been working in Lockport for over 42 years. We know the 1840s limestone homes along the I&M Canal corridor, the 1990s subdivisions off Route 7, and the split-level ranches near Lockport Township High School. That dual housing stock means two completely different chimney problems, and we carry materials for both. Our technicians are background-checked, uniformed, and trained to spot the difference between a builder-grade cap that’s simply rusted out and a historic crown that’s been quietly powderizing for decades.
Why Hearthstone Chimney Co. of Chicago Is Lockport’s Preferred Chimney Cap & Crown Company
Lockport homeowners call us back for Lockport Chimney Cleaning & Sweep. Not because we’re the cheapest, but because we document what we find and stand behind what we do. Our Level-2 camera inspections end with photos you can see and a plain-English verdict - no jargon, no scare tactics, just what is actually wrong and what it costs to fix it right.
We replaced a crumbling crown on an 1850s limestone home near the I&M Canal in Lockport’s historic district, where the original lime mortar had turned to dust. After grinding out three inches of deteriorated mortar, we installed a new copper multi-flue cap and applied a Gelco crown coating to seal against canal moisture. The homeowner still calls us for annual inspections. That’s the kind of relationship we build.
Our 90-Day Done Right Promise means if it’s not right, we come back. In writing, no arguing. We’ve honored that standard since 2014, and we plan to be in Will County for decades more. Calls are answered by a live person 24 hours a day, 7 days a week - not a voicemail, not a callback queue. Most jobs are completed in a single visit with upfront pricing: the number on the estimate is the number on the invoice.
Our Chimney Cap & Crown Services in Lockport
Custom Cap Fabrication & Installation
Lockport’s historic district demands our Fireplace Services in Lockport provide caps that fit irregular flue configurations and respect the architecture. Off-the-shelf caps from big-box stores don’t account for the tapered limestone chimneys on canal-era homes or the multi-flue setups common in larger 19th-century residences. We measure on-site, fabricate from stainless steel or copper, and install with proper clearance and fastening. A custom cap for a Lockport historic home typically runs $650-$1,200 depending on metal choice and flue count.
Crown Coating & Restoration
Not every cracked crown needs rebuilding. For Lockport’s 1990s-2000s subdivision homes with poured concrete crowns showing early hairline cracking, a professional-grade coating can add 10-15 years of service life. We use Gelco crown coating, applied after proper surface prep and masking. Crown coating in Lockport costs $350-$600. It’s not a fix for a crown that’s already spalling or separating from the brick - but for the right candidate, it’s a square deal that prevents a bigger bill later.
Multi-Flue Cap Systems
Many Lockport historic homes have two or more flues serving separate fireplaces or a fireplace and a former coal-burning heater. A single cap spanning all flues keeps water out while maintaining proper draft. We fabricate and install multi-flue caps in stainless steel or copper, with mesh screening to block wildlife. These run $580-$950 in the Lockport market. The copper option develops a patina that complements limestone and brick facades common along State Street and the canal corridor.
Crown Repair & Rebuild
When a crown has cracked through, separated from the brick, or lost its slope, coating won’t save it. We grind back to sound concrete or masonry, form and pour a new crown with proper overhang and drip edge, and seal the interface. Crown rebuilds for Chimney Repair in Lockport range from $450-$900 for standard single-flue chimneys; historic homes with larger footprints or difficult access can run higher. We use professional-grade materials from Olympia Chimney and Copperfield - no builder-grade substitutes that’ll fail in five years.

Trusted Brands We Service in Lockport
We stock parts and materials from DuraFlex, Gelco, and Olympia Chimney - brands that hold up to northern Will County’s freeze-thaw cycling and the persistent moisture that rises from the Des Plaines River valley. For Lockport customers, that means faster turnaround. We don’t order parts from a warehouse three states away and make you wait two weeks. Our trucks carry the common cap sizes, crown coating materials, and flashing components needed for most Lockport homes, whether we’re working on a 1990s colonial near Division Street or an 1860s Italianate on the canal.
Common Chimney Cap & Crown Problems We See in Lockport Homes
- Builder-spec prefab caps from 1990s subdivisions corrode at the seams after 20 years. The thin galvanized steel used in original construction on homes near Lockport Township High School and along Farrell Road rusts through at the corners, letting rain and critters enter the flue. We see this weekly. The fix is a proper stainless replacement, not another season of patching.
- Freeze-thaw cycling in the Des Plaines River valley causes hairline cracks in poured concrete crowns. Water enters, freezes, expands, repeats. Each winter the cracks widen. By year three or four, water is wicking into the masonry below. We catch this early with camera inspection; left alone, it becomes a full rebuild.
- Historic lime-mortar crowns in canal-district homes look solid but fail a probe test. This is the Lockport problem that generic chimney companies miss. Standard visual sweeps routinely undersell the tuckpointing scope on any pre-1900 structure in this corridor. We probe before we promise.
- Improperly sloped crowns pool water instead of shedding it. Builder-grade work from the subdivision boom often left flat or reverse-sloped crowns. Standing water accelerates deterioration. We rebuild with proper pitch and overhang - the way it should have been done the first time.

Lockport’s dual housing stock - 1840s lime-mortar homes and 1990s builder-spec chimneys - demands distinct cap and crown strategies that no generic chimney page addresses. Historic homes near the I&M Canal often need crown rebuilds before any cap can be properly seated; subdivision homes more often need cap replacement with crown coating to prevent future cracking. We know which is which because we’ve worked both.

FAQs - Chimney Cap & Crown in Lockport
Lockport’s canal-district homes were built with 19th-century lime mortar that powderizes under Illinois freeze-thaw cycles, a condition far more severe than in nearby suburbs with 20th-century Portland cement masonry. The original mortar simply wasn’t formulated for 150+ years of weathering, and the I&M Canal corridor concentrates ground moisture that accelerates deterioration. We probe every historic crown before recommending repair scope. Call (888) 289-6055 for an inspection - estimates are free.
A cap helps, but it cannot save a crown that’s already structurally compromised. On Lockport’s oldest homes, we often find the crown itself has disintegrated beneath a rusted or missing cap. The proper sequence is: assess and rebuild the crown first, then install a cap sized to protect the new work. Skipping the crown repair is a shortcut we don’t take. Call (888) 289-6055 and we’ll show you photos of what we’re seeing.
Not always. If the poured concrete crown beneath is sound - no through-cracks, no spalling, proper slope - we can replace the cap and apply a Gelco crown coating to extend service life. We determine this with a Level-2 camera inspection, not a guess from the ground. Many 1990s Lockport subdivision homes need only the cap and coating; some need more. The inspection gives you the real answer. Call (888) 289-6055 to schedule.
A custom-fabricated multi-flue cap in stainless steel or copper, sized to your chimney’s exact dimensions with proper mesh screening and minimum 5-inch side height. We measure on-site, account for irregular flue spacing common in 19th-century construction, and install with non-corrosive fasteners. Copper develops a protective patina that complements Lockport limestone and brick. Cost typically runs $580-$950. Call (888) 289-6055 for exact sizing and pricing.
A properly applied Gelco crown coating lasts 10-15 years in Lockport’s climate, including the elevated humidity near the I&M Canal and Des Plaines River valley. Longevity depends on surface preparation at application and whether the crown was structurally sound to begin with. We don’t coat over active cracks or separation - that’s a waste of your money. Done right, and it stands behind it. Call (888) 289-6055 for a free assessment.
