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.

AfterFast, Reliable Chimney Repair Across Marietta
Chimney repair in Marietta typically runs $850-$4,200 depending on whether you’re dealing with repointing on a historic masonry stack or a full prefab firebox replacement in East Cobb, and most jobs start with a camera inspection that same week. We’re the Chimney Repair in Marietta crew that homeowners in the Walton, Pope, and Wheeler zones call when they’ve already had one “sweep” tell them their brick fireplace is masonry and another blame a draft problem on wet wood. Our technicians are background-checked, uniformed, and licensed; you’ll get a text when we’re on the way, a written price before any tool touches your chimney, and a documented photo record when we’re done. Call (470) 480-0885 to book. Dispatch and scheduling run through our Atlanta office, but our crews live and work in Cobb County and know the difference between a Square-district lime-mortar chimney and a Lassiter Road prefab system.
Why Emberly Chimney Cleaners Sandy Springs Is Marietta’s Preferred Chimney Repair Company
We’ve completed more than 38,000 Chimney Cleaning & Sweep in Marietta and inspections since 2009, and a significant share of those have been in Marietta’s split housing market. Our Google reviews from Marietta customers consistently mention the same thing: we showed them the camera footage, named the problem in plain terms, and handed them a written price before asking for a decision.
Response time to Marietta is typically 3-5 business days for non-urgent repairs, though we keep slots open for active water intrusion or suspected liner failure. We know which East Cobb subdivisions built 1982-1994 used HeatShield-compatible firebox designs, and which historic district chimneys around Whitlock Avenue need lime-mortar repointing rather than Portland cement patches that trap moisture. That local specificity matters. A Square-district chimney spalls because freeze-thaw cycles exploit porous 19th-century brick after six humid idle months; an East Cobb prefab rusts because the metal firebox sat unventilated through those same summers. Treating them the same way wastes money and masks the real problem.
Every job is backed by our 365-Day Done Right Promise, stamped under the Haven Standard. If it’s not done right, we make it right. No exceptions.
Our Chimney Repair Services in Marietta
Chimney Rebuilding
Full chimney rebuilding in Marietta runs $3,800-$8,500 and becomes necessary when spalling, settlement, or lightning damage has compromised structural integrity. In the historic districts near Marietta Square, we rebuild with lime mortar matched to the original 1800s mix, not modern Portland that cracks the soft brick. In East Cobb’s larger properties off Shallowford Road or near Kennesaw Mountain, rebuilding often means stripping a brick facade to reveal a failed prefab firebox underneath, then replacing the entire system with a code-compliant insert or rebuilding true masonry from the roofline up. We source materials through Olympia Chimney and Famco to keep turnaround under two weeks on most rebuilds.
Mortar Repointing & Tuckpointing
Repointing in Marietta costs $18-$32 per square foot of joint surface, with most historic chimneys running $1,200-$2,800 for full crown-to-roofline work. The key is matching mortar type: lime-based for pre-1900 brick, Type N for early-20th-century construction, and never a hard overlay that accelerates spalling. We see a lot of cosmetic tuckpointing in Marietta, where a previous contractor smeared new mortar over crumbling joints without grinding out the old. It looks fine for a season, then the trapped moisture blows the face off the brick. Our Chimney Repair team grinds to a 3/4-inch minimum depth, matches the sand and binder, and documents before-and-after photos under Haven Standard Clause 4.
Spalling Brick Repair
Spalling repair in Marietta ranges from $450 for localized brick replacement to $2,200 when the damage extends through multiple courses. The historic chimneys near Church Street and Cherokee Street are particularly vulnerable: soft, porous brick absorbs summer humidity, then the occasional hard freeze in January or February expands the water into flakes and pops. We replace with salvaged or custom-matched brick where possible, and we always investigate the source, whether it’s a failed crown, deteriorated flashing, or missing chimney cap. Surface patching without fixing the water source is a waste we won’t perform.
Chimney Waterproofing
Professional waterproofing in Marietta runs $650-$1,400 depending on chimney height and accessibility, and it’s the single most cost-effective preventive repair for masonry in this climate. We apply vapor-permeable silane/siloxane sealers that let the chimney breathe while blocking liquid water, critical after Marietta’s long idle summers when no drying heat cycles through the flue. For historic chimneys, we specify products compatible with lime mortar; for newer construction near Sandy Plains Road or Davis Road, we may combine waterproofing with crown resurfacing using Gelco’s flexible crown coat. The warranty runs 10 years on materials, and we include a written moisture-readings report.
Flashing Repair
Flashing repair in Marietta typically costs $350-$875 for step-flashing replacement or counterflashing integration, and it’s often the actual source of “spalling” that homeowners attribute to brick failure. The steep-pitched roofs common in East Cobb’s 1980s subdivisions create complex intersections where cricket diverters, saddle flashings, and step flashings all need to work together. We fabricate custom flashing from 26-gauge galvanized or copper, integrate with your roofing underlayment, and photograph the sealed joint for your record.

We stock repair materials from HeatShield, Gelco, Olympia Chimney, and Famco through Haven’s buying network, which means most Marietta jobs don’t wait on shipped parts. HeatShield’s cerfractory flue resurfacing system handles localized liner damage in masonry chimneys without full relining; Gelco caps and crown coats ship same-day from our Atlanta warehouse for Marietta addresses. For prefab firebox replacements in East Cobb, we source direct-fit components from Olympia Chimney and Famco rather than forcing universal adapters that compromise draft and warranty coverage. Having the right part on the truck cuts a second visit and keeps your written price intact.
Common Chimney Repair Problems We See in Marietta Homes
- Hidden prefab failure behind brick facing. In East Cobb’s Walton, Pope, and Wheeler zones, nearly every 1970s-1990s home with brick on the outside hides a factory-built zero-clearance metal firebox. Homeowners treat it as masonry, defer maintenance, and call us when the rusted liner is already drafting carbon monoxide into the living space. The repair isn’t repointing; it’s system replacement.
- Freeze-thaw spalling in historic mortar. Chimneys around Marietta Square built with soft lime mortars wick moisture through six humid idle months, then the occasional teen-degree freeze expands that water into spalled brick and cracked crowns. Cosmetic patching accelerates the damage; proper repointing with matched lime mortar is the only durable fix.
- Multi-flue neglect. Larger Marietta properties with added gas inserts or second fireplaces often get a single annual pass on the original wood-burning flue. The second appliance, its damper, and its liner need separate inspection, and third-degree creosote glaze in the unused flue goes unnoticed until it ignites or blocks ventilation.
- Summer-idle rust in prefab fireboxes. Marietta’s long humid summers leave metal fireboxes unventilated for six-plus months with no drying heat cycling through. Rust accelerates on the flue collar, damper frame, and firebox floor; by fall, the first fire exposes gaps that weren’t visible in spring.

We Also Serve Cities Near Marietta
Our crews work throughout Cobb and north Fulton counties, including Marietta, Kennesaw, Atlanta, Acworth, and Woodstock. The housing stock shifts as you move north: Kennesaw and Acworth have fewer historic masonry chimneys and more 1990s-2000s construction with factory-built systems still within service life. Woodstock’s newer exurban builds rarely need the prefab replacement work that dominates East Cobb. We adjust our inspection focus accordingly, but the Haven Standard, Clause 4 photo documentation, and written upfront pricing apply everywhere we travel.

FAQs - Chimney Repair in Marietta
Not necessarily, and this is the single most expensive assumption we correct in East Cobb. The brick facing on most 1970s-1990s homes in the Walton, Pope, and Wheeler zones is cosmetic; behind it sits a factory-built zero-clearance metal firebox with a rated service life of 20-25 years. Those units are now 30-45 years old. We verify with a camera inspection before quoting any repair. Call (470) 480-0885 to schedule; estimates are free.
Warning signs include rust flakes in the firebox, a warped or stuck damper, drafting problems that worsen over time, and any visible corrosion on the flue collar or chimney cap. The manufacturer date, if visible on the rating plate, is definitive: most prefab systems installed during the East Cobb building boom were rated for 20-25 years. If your home was built 1985-1995 and the fireplace is original, it’s almost certainly past service life regardless of outward appearance. We document condition with camera footage and give you a written replacement quote if needed.
Yes, especially in Marietta’s climate. The six-plus humid months when your chimney sits idle cause more damage than moderate use: moisture-driven mortar deterioration in historic masonry, rust in prefab metal components, and animal nesting in uncapped flues. NFPA 211 recommends annual inspection regardless of use frequency, and our 38,000-plus inspections confirm that the worst damage we find is often in seldom-used chimneys where problems went unnoticed. The inspection includes a camera scan and photo record under Haven Standard Clause 4.
Mild overall, but Marietta gets occasional hard freezes into the teens, and that’s enough. The 19th-century brick around the Square is soft and porous; it absorbs humidity through six idle summer months, then the freeze expands that water into spalls and cracks. Portland cement patches make it worse by trapping moisture. Proper lime-mortar repointing lets the wall breathe and shed water. We’ve rebuilt crowns and repointed multiple chimneys on Cherokee Street and Whitlock Avenue using historically matched materials.
We can inspect and document all flues and appliances in one visit, but repairs may require separate scheduling depending on scope. Multi-flue houses are common in Marietta’s larger East Cobb properties, and each flue, damper, and liner needs individual camera assessment. A gas insert on one flue doesn’t protect the original wood-burning flue from creosote buildup or liner failure. We provide a written scope and price for each component, prioritized by safety, so you can phase work if needed. Call (470) 480-0885 to book a full-system inspection.
