Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterTrusted Chimney Cap & Crown for Marietta Homeowners
A properly fitted chimney cap and intact crown in Marietta typically costs between $285 and $1,450, as detailed in our Chimney Cap & Crown cost guide, depending on whether you’re adding a new cap, replacing a rusted unit, or rebuilding a cracked crown. Most cap installations and crown repairs are completed in a single visit once we’ve done a camera-scan inspection to confirm flue size and crown condition. Call (470) 288-2763 and we’ll book a time that works for your schedule.
We’ve been inspecting chimneys in Marietta since 2009, and we’ve documented more than 38,000 of them under the Haven Standard. The cap and crown are the only components standing between your flue liner and Cobb County’s weather, which is why we won’t quote either one without putting a camera down the flue first. Clause 4 of the Haven Standard requires that photo record, and we’ve delivered it on every single job since we opened.
Marietta’s freeze-thaw cycles hit harder than most homeowners expect. Water that seeps into hairline crown cracks in October expands through winter, and by March you’ve got spalling concrete, exposed rebar, and water running down into your smoke chamber. The east side of Marietta, particularly around Whitlock Avenue and the historic district, sees this pattern repeatedly in homes built between 1960 and 1995. We’ve also found that newer construction in West Cobb, around Kennesaw Mountain’s drainage patterns, often has crown pitch issues that pool water rather than shed it. See our Chimney Cap & Crown in Kennesaw service page for more on local conditions.
Our technicians are background-checked, uniformed, and licensed. You’ll get a text when yours is on the way, a written price before any work starts, and a documented photo record when it’s done. That’s Haven Standard Clause 1 and Clause 4, and it’s been our practice since day one.
What Our Chimney Cap & Crown Service Includes
Cap Installation
Cap installation is the process of fitting a protective cover over a previously uncapped flue to block rain, animals, and debris while allowing smoke and gases to vent freely. You need this if your chimney has never had a cap, if you’ve just had a new flue liner installed, or if inspection reveals that sparks from your fireplace have been landing on your roof. In Marietta, we measure the flue tile or liner opening with a digital caliper, check for proper clearance to combustibles per NFPA 211, and source the cap through our Haven buying network from Gelco or Olympia Chimney to keep your price honest.
Cap Replacement
Cap replacement removes a deteriorated, incorrectly sized, or storm-damaged cap and installs a unit that actually fits your flue. You’ll know you need this when you see rust streaks on the chimney breast, hear animals in the flue, or find the existing cap has blown off during one of Marietta’s spring thunderstorms. We see this constantly in neighborhoods near Sope Creek and the Chattahoochee River corridor, where wind exposure is higher. We remove the old cap, inspect the flue tile for cracks the old cap may have hidden, and install the replacement with stainless steel fasteners rated for Georgia’s humidity.
Crown Repair
Crown repair addresses cracked, spalled, or improperly sloped concrete crowns without tearing off the entire top of your chimney. You need this when you can see visible cracks in the crown surface, when water is entering the firebox, or when our camera inspection shows moisture damage in the upper smoke chamber. In East Cobb and the historic Marietta Square area, we’ve repaired dozens of crowns on masonry chimneys where the original builder used mortar mix instead of proper crown concrete, which lacks the air-entrainment that lets the crown expand and contract. We cut back to sound concrete, form a proper pitch, and pour a new crown that sheds water toward all four sides.
Crown Coating
Crown coating applies a specialized flexible membrane over minor crown cracks and porous concrete to seal out water without full reconstruction. This is appropriate when cracks are hairline to 1/8 inch, the crown structure is sound, and the primary issue is water absorption rather than structural failure. We don’t recommend coating over crowns with active spalling or exposed rebar, and we’ll show you the camera footage so you can see why. For qualifying crowns in Marietta, we use HeatShield CrownCoat or similar materials sourced through our network, applied after wire-brushing and priming so the bond actually lasts through our summer heat and winter freezes.
Multi-Flue Cap
A multi-flue cap is a single protective cover spanning two or more flue openings on a chimney with multiple fireplaces, appliances, or a combination of both. You need this when you have two or more flues terminating on the same chimney top and individual caps would leave gaps, or when a previous installer put on caps that don’t cover the full crown footprint. Marietta has thousands of these setups, especially in the 1970s and 1980s ranch homes around Powers Ferry Road and the subdivisions off Sandy Plains Road. We measure the full crown dimensions, account for clearances between flues, and fabricate or source a cap that protects the entire surface while maintaining proper draft for each appliance.
Custom Cap
Custom cap fabrication is required when standard catalog caps won’t fit your flue configuration, when you’re matching a historic aesthetic, or when you need special features like integrated dampers or spark arrestors for specific insurance requirements. We’ve built custom caps for homeowners in Marietta’s Whitlock Historic District where the architectural review board has material and profile requirements, and for properties near Kennesaw Mountain National Battlefield Park where copper patina was specified to match existing roofing. Our custom work is measured on-site, fabricated from stainless steel or copper through Famco or Olympia Chimney supply channels, and installed with the same written price and warranty as our standard caps.

Brands We Service for Chimney Cap & Crown
We’ve installed and serviced thousands of Gelco caps across Marietta and Cobb County since 2009. Gelco’s stainless steel line holds up particularly well in Georgia’s humidity, and their mesh sizing options let us match spark arrestor requirements to your specific appliance, whether that’s a wood-burning fireplace in East Cobb or a gas insert in West Cobb. We stock common Gelco sizes and can source specials through our Haven buying network without the markup you’d see ordering direct.
Olympia Chimney supplies both standard and custom caps we’ve used extensively for multi-flue applications and oversized flue liners. Their engineering documentation is thorough, which matters when we’re specifying a cap for a converted fireplace with a new stainless steel liner and the original flue tile is still in place. We’ve also worked with Famco for custom copper and specialized damper-integrated caps, particularly for historic properties and high-wind exposures around Sope Creek and the river corridor. Whether you have Gelco, Olympia Chimney, Famco, or any other make, we can inspect it, repair it, replace it, or fabricate something that fits.
BeforeAfterSigns You Need Chimney Cap & Crown Right Now
- Water in your firebox or rust stains on the damper. This means water is getting past your cap or crown and running down the flue. In Marietta, we see this most often after the first hard rains of spring, when homeowners light what they think is a final fire and smell wet ash. Left unaddressed, this moisture degrades your flue liner and rusts the damper assembly, turning a $400 cap replacement into a $2,000 liner job.
- Visible cracks or flaking on the crown surface. Spalling concrete on the crown is not a cosmetic issue. It’s structural failure that exposes the chimney’s interior to freeze-thaw damage. Marietta’s temperature swings, particularly in January and February when we drop below freezing overnight and hit 50 by afternoon, accelerate this damage exponentially. We’ve rebuilt crowns where the homeowner watched cracks grow for three seasons, and the repair cost tripled.
- Animals, nesting debris, or insects in the flue. Squirrels, raccoons, and chimney swifts are active year-round in Marietta’s mature tree canopy. A missing or damaged cap is an open invitation. We pulled a full squirrel nest from a flue off Canton Road last October, and the homeowner had no idea until their home inspection flagged it for sale. The odor alone can make a house unshowable.
- The cap is missing, visibly rusted, or improperly sized. A rusted galvanized cap will fail structurally and stain your chimney breast with iron oxide streaks that don’t clean off. An oversized cap creates a wind tunnel that blows out pilot lights; an undersized one doesn’t cover the flue tile properly and lets water run down the outside. We measure with digital calipers, not eyeball estimates, because half-inch errors cause full-season problems.
- White efflorescence or green algae on the chimney exterior. These are signs of chronic moisture saturation, often from a crown that isn’t shedding water or a cap that’s funneling it back toward the flue. In shaded lots common in Marietta’s older neighborhoods, algae growth accelerates the masonry deterioration. The cap and crown are your first line of defense, and when they fail, everything below them is compromised.
Our Chimney Cap & Crown Process - Step by Step
- 1
Schedule and confirm. Call (470) 288-2763 and you’ll reach a live person, not a voicemail tree. We book a two-hour arrival window that works for your calendar, and you’ll get a text when your technician is en route with name, photo, and license number. That’s Haven Standard Clause 3: verified crews, arriving on schedule.
- 2
NFPA 211 Level 2 inspection with camera scan. Before we quote any cap or crown work, we put a camera down the flue. We document flue liner condition, smoke chamber integrity, and any moisture damage that would make a cap installation pointless without addressing the underlying issue. You see what we see. Clause 4 of the Haven Standard requires this photo record, and we’ve delivered it on every job since 2009.
- 3
Written price, written scope, written warranty. We don’t start work until you’ve approved a document that specifies exactly what we’re doing, what materials we’re using, what it costs, and what our 365-Day Done Right Promise covers. Haven Standard Clause 1: have it in writing. No verbal quotes, no “we’ll figure it out when we get up there,” no surprises when the invoice arrives.
- 4
Cap or crown work with ongoing documentation. For crown repairs, we form, pour, and tool the new surface with proper pitch and drip edges. For cap installations, we verify fit with a smoke test and check draft performance. For coatings, we apply per manufacturer spec with recorded mil thickness. We photograph before, during, and after. If we’re on your roof, you’re getting documentation of what we found and what we did.
- 5
Final walkthrough and archived record. Your technician reviews the photo record with you, explains any findings that affect future maintenance, and emails you the complete documentation package within 24 hours. This archive is yours permanently. If you sell your home, if your insurance asks, if you need warranty service, it’s all there. We’ve had Marietta homeowners call us five years later for a copy, and we pull it in minutes.
How Much Does Chimney Cap & Crown Cost in Marietta?
A standard single-flue stainless steel cap installation in Marietta typically runs $285-$495, depending on flue size, accessibility, and whether we need to remove an existing damaged cap. Crown coating for a sound crown with minor cracking usually falls between $425 and $675. Full crown repair or reconstruction ranges from $850 to $1,450, with the upper end covering larger chimneys, difficult access, or the need to rebuild after significant spalling. Custom caps and multi-flue units start around $650 and scale based on material, complexity, and fabrication time.
Several factors move these numbers. Roof pitch and height affect labor time and safety equipment needs; we won’t quote a three-story steep-pitch job without seeing it. Crown size and the number of flues obviously scale material costs. Hidden damage that our camera inspection reveals, such as a cracked flue tile beneath a rusted cap, may need to be addressed before the new cap goes on, and we’ll show you that footage before adding anything to the scope.
To avoid overpaying, get any competitor’s written estimate in hand and bring it to us. Our Free Second Opinion policy means we’ll review their scope and pricing against what we find, and we’ll explain where the differences are. We’ve seen Marietta homeowners quoted for full crown rebuilds when crown coating was appropriate, and quoted for standard caps when the flue configuration required a custom solution. The camera footage doesn’t lie, and we don’t quote what we can’t document.
Every free estimate includes the NFPA 211 Level 2 inspection, camera scan, and photo record. There’s no separate trip charge, no inspection fee that gets waived if you buy. The price we write is the price you pay, and it’s delivered before any work starts.

Frequently Asked Questions - Chimney Cap & Crown in Marietta
Chimney cap and crown service covers the installation, repair, and replacement of the protective components at the top of your chimney. The cap is a metal cover that keeps rain, animals, and debris out of your flue while allowing smoke to escape; the crown is the concrete or mortar surface that sheds water away from the flue opening and protects the chimney’s structural masonry. In Marietta’s climate, both components take a beating from UV exposure, thermal cycling, and wind-driven rain, which is why we inspect them with a camera scan before quoting any Chimney Cap & Crown in Marietta work.
Most cap installations and replacements are completed in 1-2 hours once we’re on site. Crown coating takes 2-3 hours including surface prep and cure time before we can apply the final layer. Full crown repair or reconstruction typically requires 4-6 hours and may need a return visit if weather doesn’t cooperate with curing conditions. We’ll give you a specific time estimate in your written scope before work starts, and we’ll call (470) 288-2763 if anything we find during inspection changes that timeline.
A standard cap installation in Marietta runs $285-$495, crown coating is $425-$675, and full crown repair ranges $850-$1,450 depending on size and access difficulty. Custom caps and multi-flue installations start around $650. The exact price depends on what our camera inspection reveals about your flue condition and crown integrity. Call (470) 288-2763 for a free estimate with written pricing before any work begins.

We stock common sizes and source specials through our Haven buying network, which means we don’t mark up materials the way retail distributors do. If you have a different brand, or you’re not sure what brand you have, we’ll identify it during inspection and quote accordingly.
Active water intrusion into your firebox or living space should be addressed promptly to prevent flue liner damage, smoke chamber deterioration, and interior water damage to framing and drywall. We don’t use scare tactics, but we will show you the camera footage of what water is already doing inside your chimney. Call (470) 288-2763 and we’ll prioritize your appointment based on the severity of what we see. Our live phone support runs 24 hours a day, 7 days a week.
Every job is backed by our 365-Day Done Right Promise: if it’s not done right, we make it right. This covers installation quality, material defects, and workmanship issues. Manufacturer warranties on caps vary by product line, and we’ll specify what’s covered in your written scope. Haven Standard Clause 5 requires that warranty documentation be delivered with your final photo record, so you have it in writing if you ever need it.
Clear a path to your fireplace so our technician can access it for the camera inspection, and make sure we can reach your roof safely, which means clearing patio furniture or obstacles from the work area and securing pets indoors. You don’t need to clean the fireplace or move anything heavy. We’ll bring drop cloths, shoe covers, and our own equipment. If you have a competitor’s written estimate you’d like us to review, bring that too, our Free Second Opinion is always available.
