Why Flint Chimney Co Alpharetta Is Dunwoody’s Preferred Chimney Repair Company
We’ve built our reputation in Dunwoody on doing exactly what the written estimate says, for exactly the price on that estimate. Homeowners around Vermack Road, Womack Road, and Redfield have called us after other companies went quiet, moved the number at the door, or left mortar dust across a finished basement. That doesn’t happen on our watch. Our technicians are background-checked and uniformed, and they run under The Garrison Standard, the same operating code every Garrison Partners location follows. You’ll know who’s walking through the door and what they’ll do before any tool comes off the truck.
Dunwoody’s housing stock works in our favor. We know these chimneys, the 1970s brick colonials off Mount Vernon and the larger stone-front builds in newer subdivisions. That local familiarity means we can often diagnose a draft problem or moisture leak faster, because we’ve repaired the same failure mode three streets over. A live person answers our phone 24 hours a day, seven days a week, so when you call with a chimney emergency in Dunwoody, you’re not leaving a voicemail and hoping.

Chimney Masonry Repair in Dunwoody
Chimney masonry repair in Dunwoody usually means repointing mortar joints, rebuilding a cracked crown, or replacing spalled bricks that have popped loose after years of rain and freeze cycles. Older brick chimneys in Dunwoody, especially those built between 1970 and 1990, hide a problem we see constantly: mortar joints that look intact from the ground but are crumbled an inch deep behind the surface. Water gets in, freezes during a January cold snap, and the face of the brick pops off. A typical repointing job in Dunwoody runs $450 – $1,800 depending on how much of the stack needs work. Full crown rebuilds with proper overhang and a drip edge run $600 – $1,400.
Waterproofing and Flashing Repair
Dunwoody’s heavy tree canopy means pine needles and leaves sit on chimney crowns and behind flashing for months at a time. That trapped moisture is the number one cause of spalling brick and crown cracks in this area. We repair and replace flashing around the roofline, then apply a vapor-permeable waterproofing treatment like Gelco to the masonry so water stays out while the brick can still breathe. A flashing repair with waterproofing on a Dunwoody chimney runs $400 – $1,100.
Full and Partial Rebuilds
When a Dunwoody chimney has deteriorated past the point of patching, we rebuild from the roofline up or from the firebox up, depending on where the failure sits. These are honest conversations. Hank’s rule is simple: if a repair can safely extend the life of the chimney for five to ten years, we say so and quote that. If a rebuild is the only safe option, we show you the photos and the written reasoning, never just a number.
Chimney Cap Installation in Dunwoody
Chimney cap installation in Dunwoody is one of the highest-value repairs we do, particularly for homes on wooded lots where pine needles and oak leaves clog flues within a season. A properly sized stainless cap keeps debris out, stops rain from pouring down an unused flue, and prevents birds and squirrels from nesting in the smoke chamber. We install caps from Olympia Chimney and Famco because they hold up to Atlanta’s humidity and the sun exposure you get on a south-facing roof in Dunwoody. A standard stainless cap installation here runs $250 – $600 installed, including the masonry bolts and a watertight seal at the flue tile.
Multi-Flue Caps for Large Homes
Many Dunwoody homes have two or three flues running side by side, often serving a fireplace, a furnace, and a water heater. A single-flue cap doesn’t solve that problem. We measure the crown and install a full-coverage multi-flue cap that protects all the openings while preserving proper draft for each appliance. This is common on larger colonials around Dunwoody Club Drive and Tilly Mill Road.
When a Cap Won’t Fix the Problem
A cap stops new water and debris from entering, but it can’t reverse damage already inside the flue. If you’ve had a missing or damaged cap for years, we’ll run a camera inspection to check for cracked flue tiles, spalled liner sections, and creosote glaze before quoting any cap work. You’ll see the footage yourself and decide with the facts in front of you.
Trusted Brands We Service in Dunwoody
We don’t install whatever is cheapest on the truck. On Dunwoody jobs we specify and install HeatShield for smoke chamber and flue resurfacing, DuraFlex for stainless steel relining, and Gelco for masonry waterproofing. These are trade-grade products with documented performance histories, which matters on tall chimneys that take the brunt of Atlanta storms. Because Dunwoody is a regular service area for us, we keep common cap sizes, damper parts, and liner components in local stock, so we’re not delaying a repair for a week waiting on a shipment.

AfterCommon Chimney Repair Problems We See in Dunwoody Homes
- Shallow smoke shelves and narrow flues in older colonials. Homes built in the 1970s and 1980s across Dunwoody often have undersized flues and shallow smoke shelves that fill with creosote fast. We see third-degree tar glaze in these chimneys more than anywhere else we work.
- Moisture damage from heavy tree cover. Pine needles and oak leaves pile up on crowns and behind flashing, holding water against the masonry for months. That leads to moss growth, spalling brick, and crown cracks that widen every winter.
- Hidden mortar failure behind intact brick faces. Dunwoody’s humid, wet climate accelerates mortar breakdown behind the surface. A chimney can look structurally fine from the yard and be dangerously soft two inches deep, which is why we recommend a Level 2 camera inspection before most repairs.
- Draft failures from multi-appliance systems. Large Dunwoody homes with multiple fireplaces, a furnace flue, and a water heater flue often have draft imbalance when one appliance is upgraded or one flue is neglected. We diagnose the whole system, not just the fireplace you use most.
Pricing for Chimney Repair in Dunwoody, GA
Chimney repair pricing in Dunwoody starts around $250 for a cap installation and runs to $2,800 for a full flue relining with a stainless steel liner. Most masonry work falls between $450 and $1,800. What moves the number is access, chimney height, and how much of the hidden flue has already failed. A chimney that’s easy to reach off Mount Vernon Road will cost less to work on than a three-story rear chimney that requires staging. We give a written price before any work starts, and that number doesn’t move unless you approve a change order in writing. Call (762) 600-1468 for a free estimate.
We also handle broader Chimney Repair work for homeowners deciding between a targeted fix and a full system rebuild.

FAQs About Chimney Repair in Dunwoody
Every fireplace and flue should be inspected annually, even if you only use one regularly. Homes in Dunwoody with two or three fireplaces plus a furnace flue and water heater flue have multiple systems that can fail independently. Annual inspection catches shallow smoke shelf buildup and moisture intrusion before a repair becomes a rebuild. Call (762) 600-1468 to schedule, and we’ll coordinate all flues in one visit.
You have three realistic paths: a mechanical creosote removal if the buildup is glaze but the flue is intact, a HeatShield resurfacing to smooth and seal a cracked flue, or a full DuraFlex stainless steel relining if the original tile liner has spalled. In older Dunwoody colonials, we often see a combination: shallow smoke shelf plus narrow flue plus cracked liner. We’ll show you camera footage and quote each option in writing before you decide.
Look for spalling brick faces, white efflorescence staining, moss growth on the crown, rust streaks from the flashing, or mortar joints that crumble when you run a key across them. Any of these means water has entered the masonry and is working on it from the inside. In Dunwoody’s wet climate, a small crown crack becomes a structural problem within two or three winters. Call (762) 600-1468 and we’ll put it on paper for you.
Yes, and we do it often in Dunwoody because shallow smoke shelves and narrow flues create exactly the conditions where glaze forms fast. A brush won’t remove third-degree glaze. We use mechanical removal tools to break it down, then camera-inspect the flue for damage underneath. If the liner is cracked, we’ll recommend HeatShield or a DuraFlex liner, with a written quote before any work starts.
If your current cap is cracked, rusted, or missing, yes, and the sooner the better. Pine needles on a Dunwoody lot will pack a flue within a single season and create a chimney fire risk. A stainless cap from Olympia Chimney or Famco installed to your flue tile solves it. If you aren’t sure whether your cap is doing its job, call (762) 600-1468 and we’ll check it during an inspection.
