Fast, Reliable Chimney Cap & Crown Across Lilburn
If your chimney cap is rusted through or your crown has hairline cracks spreading like a web, water is already getting in. In Lilburn’s 55-inch annual rainfall, that means damaged fireboxes, rotted framing, and repairs that multiply by the season. We answer calls from Lilburn homeowners with a live person, day or night, and our technicians are usually on site within 24 hours. Call (844) 803-1545 for a free estimate.
We’ve been driving the same Gwinnett County roads since 1984. We know the difference between a 1978 brick ranch off Lawrenceville Highway and a 1992 traditional near Killian Hill Road, and we know which one likely has a rusted sheet-metal chase cover held on by corroded screws. That local knowledge saves you time and money.
Why Hearthstone Chimney Co. Is Lilburn’s Preferred Chimney Cap & Crown Company
Lilburn homeowners don’t want a hard sell. They want someone who shows up when promised, explains what they found, and fixes it without surprises. We’ve earned that reputation here over four decades, one chimney at a time.
Our Lilburn customers tell us the same thing: the last company gave a verbal quote that doubled on the invoice. We don’t do that. Our upfront pricing means the number on your estimate is the number on your bill. Period.
Response time matters when water is pouring through a cracked crown. From our dispatch, we typically reach Lilburn properties in under 45 minutes during business hours. Emergency calls get same-day scheduling, and most cap and crown jobs finish in a single visit.
We also understand the local housing stock. The prefabricated fireplace systems common throughout 30047 and 30048 weren’t built to last 40 years, yet many are still in service. When we inspect your cap or crown, we’re also checking whether the chase cover, refractory panels, and firebox liner are failing. That thoroughness prevents the callback.
Our Chimney Cap & Crown Services in Lilburn
Chimney Cap Installation
New cap installation in Lilburn typically serves homeowners with missing caps or builder-grade spark arrestors that have rusted away. We measure your flue or chase opening precisely and fabricate a cap that fits, not a universal size that gaps or blows off in Georgia wind. Our Chimney Cap & Crown team uses stainless steel and copper options from Famco and Copperfield, sized for single-flue masonry or multi-flue prefab chases common in Lilburn’s 1980s subdivisions.
Chimney Cap Replacement
Replacement is our most frequent cap call in Lilburn. The sheet-metal chase covers on prefab units installed during the Gwinnett County building boom were galvanized steel with a 15-20 year lifespan. Thirty years later, they’re perforated with rust holes that let rain straight onto the firebox. We remove the old cap, inspect the chase top for rot, and install a proper replacement that sheds water correctly. Most replacements run $280-$450 in the Lilburn market.
Crown Repair
True masonry crowns are rare in Lilburn’s prefab-heavy housing stock, but they do exist on older homes near Old Town and along Main Street. When we find a cracked concrete crown, we don’t slap caulk on it. We grind out the crack, apply a bonding agent, and rebuild with proper crown mix sloped to drain. For minor cracking, crown coating with HeatShield provides a waterproof membrane that flexes with temperature swings. Crown repair in Lilburn typically costs $350-$650 depending on accessibility and damage extent.
Crown Coating
Crown coating buys time for masonry crowns with surface cracking but sound structure. In Lilburn’s climate, where freeze-thaw cycles are mild but relentless moisture is the real enemy, a proper coating prevents the crack from becoming spalling concrete and exposed rebar. We apply professional-grade crown sealant in two coats, with a cure time that accounts for Georgia humidity. This is preventive work, and we tell you honestly when coating isn’t enough and rebuild is the only lasting fix.
Multi-Flue Cap
Homes with multiple fireplaces or a boiler flue plus fireplace need multi-flue caps that cover the entire chimney top with proper clearance. We’ve installed these on larger Lilburn homes near Tribble Mill Park and in the Parkview school district, where 1990s builds sometimes feature dual flues. A single multi-flue cap eliminates the gap between separate caps where leaves and water collect.
Custom Cap
Oversized flues, decorative chimney pots, or historic homes near Lilburn’s original downtown sometimes require custom fabrication. We measure, sketch, and order from Copperfield or fabricate locally in stainless or copper. Custom work runs $600-$1,200 in Lilburn depending on metal choice and complexity.

Common Chimney Cap & Crown Problems We See in Lilburn Homes
- Rusted-through chase covers on prefab fireplaces. The galvanized steel covers installed in Lilburn’s 1970s-1990s housing boom have exceeded their design life by a decade or more. We regularly find covers with holes large enough to drop a pencil through, letting rainwater soak the firebox and rust the damper.
- Cracked refractory panels behind “working” fireplaces. Homeowners on Lawrenceville Highway and throughout the Parkview district tell us their fireplace still lights, so it must be fine. But fractured refractory panels allow combustion heat to reach combustible framing inches away. The cap and crown inspection often reveals this hidden danger.
- Improperly flashed chimney chases. Builder-grade flashing on Lilburn’s rapid-construction homes separated from siding years ago. Water runs behind the chase siding, rots the OSB, and exits inside the home. We see this on two-story traditional homes near Killian Hill Road and in subdivisions off Five Forks Trickum Road.
- Missing or damaged spark arrestors. Georgia’s humid summers and sporadic winter burns mean creosote builds up in arrestor screens, which then corrode or get removed by homeowners who don’t understand their fire-safety function. A proper cap with integrated arrestor replaces both problems.
