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.

Chimney repair in Cumming, GA typically runs $185 to $1,900 depending on the job, and you should know the price before you book, not after the crew arrives. That is how Flint Chimney Sweep has operated since 2002, under the same Garrison Standard every Garrison Partners location follows.

Call (830) 251-4560 and a live person answers, day or night. We put a written price in front of you before any tool comes off the truck.
Why Flint Chimney Sweep Is Cumming’s Preferred Chimney Repair Company
Cumming homeowners call us for the same reason they keep calling us back after the first job: the number on the written estimate is the number on the invoice. No door-to-door upsell, no photo of a mystery crack with a $4,000 cure. Every chimney repair we do in Cumming carries our 365-Day Done Right Promise, a written guarantee valid for one full year from the service date. If a covered repair fails inside that year, we return at no charge. No argument, no re-quoting, no fine print.
Our technicians are background-checked and uniformed, so when someone knocks on your door in Cumming, you know exactly who you are letting in. The phones are answered by a live person 24/7, not a recording that promises to call you back. We dispatch from the Atlanta office, but the crews that serve Cumming work this territory every week, and they know the difference between a 1970s masonry flue in an in-town home and a factory-built pipe in a 2015 Craftsman off Bethelview Road.
Chimney Flashing Repair in Cumming
Chimney flashing repair is one of the most frequent calls we get in Cumming, because the seal where your roof meets the chimney brick fails long before the chimney itself does. Flashing is the metal barrier, usually aluminum or galvanized steel, that keeps water from running down the gap between chimney and roof deck. In Cumming’s newer subdivisions, builder-grade galvanized flashing rusts through in as few as eight years. When that happens, rainwater tracks down the chimney chase and shows up as a brown stain on the ceiling near the fireplace. That stain gets blamed on the chimney, but the fix is the flashing.
We remove the old flashing, cut the mortar joint, install new step and counter flashing, and seal it with a professional-grade urethane sealant. On most Cumming homes, flashing repair runs $350 to $800. You get a written price before we start.
What a Rusted Flashing Repair Looks Like
We cut out the old metal, inspect the mortar joint behind it, and install new flashing tucked into the brick, not just caulked on the surface. Surface-only flashing jobs leak again inside two winters. We do not do surface-only.
Flashing vs. Crown: Which One Is Leaking?
If water shows up after heavy rain and the ceiling stain runs from the chimney toward the room, suspect flashing. If the chimney brick itself is damp or you see cracks in the concrete top, it is the crown. In Cumming we often find both at once on 1990s brick ranches.
Chimney Crown Repair in Cumming
Chimney crown repair in Cumming addresses the concrete cap on top of your masonry chimney, the first line of defense against Georgia rain and hail. The crown is the sloped concrete top that sheds water away from the flue. When it cracks, water seeps into the brick below. Over two or three Cumming winters, that water freezes and expands, popping the brick faces off. The damage is called spalling, and by the time you see brick chips in the yard, the repair has already moved from a $250 crown patch to a $1,200 brick repair.
A standard crown repair in Cumming runs $450 to $900, depending on the size of the crown and how much rebuilding it needs. We do not smear caulk over the crack and call it fixed. We remove the damaged concrete, form and pour a new crown with a proper drip edge, and treat the surrounding brick so water cannot re-enter.
Hail Damage and the Cumming Crown
Cumming gets spring hail storms that knock caps off and pit the crown surface. A pitted crown holds water, and water is what kills chimneys here. If your cap is dented or gone after a spring storm, schedule an inspection before the next rain cycle.
Can a Cracked Crown Wait Until Fall?
A hairline crack can usually wait. A crack you can slide a quarter into cannot. Every month you wait, another rain cycle pushes water deeper into the brick. We will tell you straight if the repair can wait, and we put that in writing too.
Trusted Brands We Service in Cumming
We install and service Chimney Repair materials from brands that hold up in North Georgia weather. For most Cumming flue jobs we specify HeatShield, a ceramic-bonded repair system that restores a cracked clay liner without a full rebuild. For metal chimney parts we use Copperfield caps and dampers, and for factory-built systems we stock Olympia Chimney components. That means when you need a crown repair or a flashing replacement in Cumming, we are not waiting on a distributor in another state. Parts arrive on the truck, the job gets done, and the guarantee is in your hand before we leave the driveway.
Common Chimney Repair Problems We See in Cumming Homes
- Missing caps after spring hail. Cumming’s spring hail storms knock caps off or dent them, letting rain pour straight into the flue. Water in the smoke chamber soaks the brick, and within a season you have spalling and musty odors.
- Rusted flashing on new-build chimneys. Subdivisions around Cumming use builder-grade galvanized flashing where chimney meets brick. It rusts through early, and the leak gets blamed on the chimney when it is really the metal.
- Third-degree creosote inside flue liners. Slow-burning green wood leaves a hard, glazed tar on the flue walls. Brushes cannot remove it, and it is the kind of creosote that fuels chimney fires. This requires chemical treatment or a liner replacement.
- Cracked clay flue tiles in older brick homes. Homes built in Cumming before the mid-1990s often have clay tile liners that crack from cycle after cycle of heating and cooling. Creosote and moisture leak through the cracks into the surrounding mortar.

FAQs About Chimney Repair in Cumming
Every two years, even with light use. The inspection is not about how often you burn; it is about what happens to the chimney when it is sitting idle. In Cumming, water is the bigger threat than fire. A Level 1 inspection catches a cracked crown or missing cap before it becomes a brick repair. If you burn every weekend through the season, inspect annually.
First-degree creosote is a light, flaky soot that a standard sweep removes with a brush. Third-degree creosote is a hard, glazed tar that forms when slow-burning green wood keeps flue temperatures too low to burn it off. Brushes cannot remove third-degree creosote, and it is the fuel that a chimney fire feeds on. In Cumming, we see it most often in fireplaces that burn a lot of pine. A camera inspection tells us which kind you have, and we put the photo in your report.
You get a written price before any work starts, and we never charge by the hour. A standard chimney sweep in Cumming runs $185 to $275. Flashing repair runs $350 to $800. A crown repair runs $450 to $900. That is the price on the invoice, no hourly surprises. Call (830) 251-4560 for an exact quote, and the estimate is free.
It depends on the size of the crack and how far the rust has gone. A hairline crack in the crown can usually wait a few months. A crack you can fit a quarter into cannot, because every rain pushes water deeper into the brick. Rusted flashing that is already showing a ceiling stain means water is inside your home now, and that is not a fall job. The right answer is a camera inspection. Then you decide with the photo in front of you, not on a guess. Call (830) 251-4560 and we will give you a straight answer.
Yes. We carry both rotary and hand brushes on every Cumming truck because the job is not one size fits all. Factory-built metal chimneys get the rotary treatment to clean the pipe without damaging the metal. Masonry flues, especially older ones in Cumming’s brick homes, often need hand-scrubbing to remove first-degree creosote from the tile seams. We service both types, and the photo report shows you which one you have and what we did.
When you are ready for a straight answer and a written price, call Flint Chimney Sweep at (830) 251-4560. A live person answers, we schedule a time that fits your week, and the estimate is free. That is the Garrison Standard, and it applies to every chimney repair we do in Cumming.
