We’ve inspected more than 38,000 chimneys since 2009, and the cap and crown failures we find through our Chimney Cap & Crown in Kennesaw follow a clear pattern. The freeze-thaw cycles between December and March, combined with the clay-heavy soils around Noonday Creek and north toward Kennesaw Mountain, create lateral shifting that cracks concrete crowns at their weakest points. Water gets in, steel reinforcement rusts and expands, and by spring the homeowner has spalling brick, a leaking flue, or worse - a crown that’s detached entirely and sitting in the firebox. Our NFPA 211 Level 2 inspection with camera documentation catches this before the repair bill doubles. Every job we quote gets a written scope, written price, and written warranty under the Haven Standard. Corrine Halstead built this practice into Clause 1 of the Haven Standard - “Have it in writing” - because a verbal quote that changes once the ladder is up isn’t a quote at all.

What Our Chimney Cap & Crown Service Includes

Cap Installation

A chimney cap is a metal cover that sits over your flue termination, keeping rain, animals, and wind-blown debris out while allowing smoke and combustion gases to escape. In Kennesaw, we install caps on homes that never had one - common in 1980s and 1990s construction around Legacy Park and Barrett Lakes - and on chimneys where the original cap was removed and never replaced. We measure your flue precisely, source from Gelco or Olympia Chimney through our Haven buying network, and install with stainless steel fasteners rated for the wind exposure you get on the ridges above Kennesaw Mountain National Battlefield Park. Your written price includes the cap, hardware, and a photo record of the finished installation under Haven Standard Clause 4.

Cap Replacement

Cap replacement becomes necessary when the existing cap has rusted through, blown off in a storm, or was improperly sized from the start. We see this frequently in the Town Center area, where cheap galvanized caps from big-box stores last three to five years before the salt air from I-75 traffic accelerates corrosion. Our replacement process starts with a camera inspection of the flue interior - Clause 4 requires it - to document any water damage that occurred while the cap was failing. We then match a stainless steel or copper cap from Famco or Copperfield to your flue count and dimensions, with a written price locked before we climb. The old cap comes off, the flue crown gets inspected for hidden cracks, and the new cap gets sealed with a high-temp silicone rated to 500°F.

Crown Repair

The crown is the concrete slab that tops your masonry chimney, sloped to shed water away from the flue. Crown repair addresses cracks, spalling, and deterioration before water reaches the brick below. In Kennesaw’s older neighborhoods like Cherokee Street and around Southern Polytechnic’s original campus, we find crowns poured without proper overhang or expansion joints - design flaws that guarantee premature failure. Our repair process opens each crack to sound concrete, fills with a flexible crown sealant, and applies a waterproofing treatment that maintains vapor permeability so trapped moisture can escape. For crowns with extensive spalling or exposed rebar, we’ll tell you honestly when repair is a Band-Aid and full replacement is the sounder spend. That conversation comes with photos you can see, not a sales pitch.

Crown Coating

Crown coating is a preventive application of elastomeric sealant over structurally sound concrete that hasn’t yet cracked deeply. It’s the most cost-effective cap and crown service we offer in Kennesaw, and we recommend it for crowns showing surface crazing or minor hairlines - the stage before water infiltration accelerates. We use HeatShield CrownCoat or equivalent materials sourced through our Haven network, applied to a dry, clean surface after wire-brushing loose material. The coating cures to a flexible membrane that bridges small cracks as the chimney expands and contracts through Kennesaw’s temperature swings. A typical coating lasts 10-15 years with proper maintenance, and we document the “before” condition with camera footage so you have a dated baseline for comparison at your next inspection.

Multi-Flue Cap

A multi-flue cap is a single metal cover that shelters two or more flue terminals on chimneys serving multiple fireplaces, a fireplace and a furnace, or a fireplace and a wood stove. These are standard on larger homes in Kennesaw’s newer developments - Legacy at Kennesaw, Swift Creek, and the estates along Stilesboro Road - but they’re often undersized or installed without proper clearance to combustibles. Our multi-flue caps from Olympia Chimney are custom-measured to your chimney’s footprint, with screened sides that keep out squirrels and raccoons without restricting draft. We verify adequate combustion air supply and document flue separation with our camera scan, since a cracked partition between flues can allow exhaust gases to cross-contaminate. The written quote specifies cap gauge, mesh size, and fastener type - no surprises.

Custom Cap

Custom caps are fabricated to non-standard dimensions or architectural requirements - copper caps on historic homes, oversized coverage for chimney pots, or designs matching HOA specifications in gated communities. We’ve built custom caps for homes in Kennesaw’s historic district and for properties where the chimney terminates below roofline and needs an extended skirt to shed water properly. Corrine Halstead reviews every custom order personally, verifying measurements against our photo documentation and confirming material specs with the fabricator before production begins. Custom work carries the same written price guarantee and 365-Day Done Right Promise as our standard services, with delivery timelines quoted upfront so you’re not waiting through burning season.

Brands We Service for Chimney Cap & Crown

We source chimney cap and crown materials through the Haven buying network, with direct relationships to manufacturers that keep our prices honest and our lead times short. Gelco caps are our go-to for standard single-flue installations - we’ve fitted thousands of their stainless steel models across Cobb County, and we stock common sizes for same-visit replacement when your cap has failed catastrophically. Their mesh design handles the pine straw and oak tassels that clog cheaper caps every spring in Kennesaw’s tree-canopied neighborhoods.

Olympia Chimney supplies our multi-flue caps and most of our custom-fabricated orders, with a product range that accommodates the complex chimney configurations we see in larger homes around Kennesaw. Famco and Copperfield round out our inventory for specialty applications - copper architectural caps, wind-resistant designs for exposed ridge lines, and extended flue covers for chimneys with draft issues. Whether you have a Gelco cap that needs replacement, an Olympia multi-flue cover that blew loose, or any other make installed by a previous homeowner, we can service it, document its condition, and quote repair or replacement in writing before any work starts.

After

Signs You Need Chimney Cap & Crown Right Now

• Water stains on the ceiling near your fireplace. This means moisture is entering through a failed crown or missing cap, traveling down the flue, and exiting at the nearest penetration. In Kennesaw homes with vaulted ceilings over the firebox, the stain may appear 10-15 feet from the chimney itself. Left unaddressed, the drywall damage is the least of it - the flue liner and smoke chamber behind that wall are getting saturated.
• Rust flakes in your firebox or on the damper. Rust indicates chronic water entry, and the damper is often the first steel component to show it. A damper that won’t open fully or seats unevenly may have warped from rust expansion. We document this with camera footage and measure the flue for liner damage while we’re at it - water and creosote together accelerate corrosion of stainless steel liners.
• Spalling brick or deteriorating mortar on the chimney exterior. Spalling is when the face of the brick pops off from freeze-thaw cycling, and it’s almost always traceable to a crown that isn’t shedding water properly. In Kennesaw, we see this concentrated on the north and west exposures where winter wind drives rain into crown cracks. The repair cascade goes: crown, then brick, then possibly liner - and the sooner we catch it, the shorter that cascade.
• Animal sounds or debris in the flue. Squirrels, raccoons, and chimney swifts don’t need much invitation. A missing cap or one with damaged screening is an open door. We remove nesting material - it’s a fire hazard and it blocks draft - then install properly screened replacement from our stock. Georgia law protects chimney swifts during nesting season; if we find an active nest, we’ll document it and schedule cap installation once the young have fledged.
• Visible cracks in the crown surface, especially at the flue joints. Hairline cracks are normal as concrete cures, but cracks that widen seasonally or run parallel to the flue tile indicate structural movement. We map these with photo documentation and classify them: sealable, repairable, or requiring full crown replacement. Kennesaw’s expansive clay soils make this assessment critical - a crack that’s static in sandy soil may be actively widening here.

Our Chimney Cap & Crown Process - Step by Step

1. 1
   Schedule your NFPA 211 Level 2 inspection. Call (678) 535-2204 and you’ll reach a live person, any time of day. We book appointments across Kennesaw and surrounding areas with a two-hour arrival window, and you’ll get a text when your technician is en route. Your assigned tech is background-checked, uniformed, and their license number is on the paperwork you’ll receive.
2. 2
   Camera-scan documentation of the full system. We run a high-resolution camera from the firebox to the flue termination, recording crown condition, cap attachment, flue liner integrity, and any water damage patterns. This footage becomes your dated record under Haven Standard Clause 4 - not a verbal summary, but video you can review. We also photograph the crown and cap from the roof for exterior documentation.
3. 3
   Written diagnosis and price, delivered before work starts. Your technician reviews the footage with you, explains what was found in plain terms, and presents a written scope with line-item pricing. This is Haven Standard Clause 1: “Have it in writing.” No work begins until you approve the price. If the inspection reveals no immediate need for cap or crown work, we tell you that too - with the documentation to back it up.
4. 4
   Cap or crown work with photo-recorded completion. Approved work proceeds with materials from our Haven network - Gelco, Olympia Chimney, Famco, or Copperfield as specified in your quote. For crown repairs, we photograph each stage: crack prep, sealant application, curing verification. For cap installations, we document proper overhang, fastener torque, and mesh clearance. You see what was done, not just the finished appearance.
5. 5
   Written warranty and 365-Day Done Right Promise. You receive a completed work summary with photos, material specifications, and warranty terms before we leave. The 365-Day Done Right Promise is stamped on every job: if anything isn’t right, we make it right. That includes callbacks for sealant issues, fastener loosening, or any concern about draft performance. Your documentation stays in our archive for future reference - we’ve maintained these records continuously since 2009.
