Hank Delano leads our Alpharetta repair crews, and he’s spent more than two decades learning exactly how North Georgia weather works against masonry and metal. Freeze-thaw cycles in Johns Creek and Roswell crack crowns and Spalling Brick Repair needs arise faster than most homeowners realize. We document everything with photos, give you a flat price on paper, and don’t touch a single tool until you approve it.

Chimney Cap Installation

Chimney Cap Installation means adding a metal cover over the flue opening at the top of your chimney to keep rain, animals, and debris out. Most Alpharetta homes without caps see water damage within three to five years because Georgia storms drive rain almost horizontally. We install stainless steel and copper caps from Gelco and Copperfield, fit them to your exact flue dimensions, and typically charge $350 to $800 for a standard installation with the cap included. The cap is secured with mechanical fasteners and a weatherproof seal, never just set in place.

When Alpharetta homes need a cap

If you hear birds or squirrels inside the chimney, see twigs falling into the fireplace, or notice rust streaks on the chimney crown, you almost certainly need a cap installed. Open flues also let pine needles from Milton and Mountain Park yards into the smoke chamber, which creates a fire hazard we’d rather you avoid.

The Finn Chimney Co approach

We measure the flue opening exactly, then build a quote for the cap, the fasteners, and the labor. Hank Delano’s crews show up with the right cap on the truck, complete the install in under two hours in most Alpharetta neighborhoods, and leave you with a photo report showing what was installed and why. Your written invoice states the guarantee terms line by line.

Chimney Cap Replacement

Chimney Cap Replacement involves removing an old, damaged cap and installing a new one that actually fits and seals the flue. A cap that’s rusted through, blown off in a storm, or sized wrong for the flue is the most common call we get after high winds move through Dunwoody, Duluth, and Norcross. Replacement typically runs $300 to $700 depending on flue size and material. We reuse the existing mounting holes only when they’re sound; if they’re stripped or corroded, we drill new ones and seal the old.

Rust and blow-off failures

Galvanized caps from big-box stores rarely last more than a few Georgia seasons. We replace them with stainless steel or copper caps that hold up to heat, rain, and the acidic residue from wood smoke. A replacement cap from Olympia Chimney or Copperfield comes with a manufacturer’s material warranty plus our one-year workmanship guarantee.

When you can wait versus when to act

A missing cap in July is less urgent than one missing in October, but raccoons don’t check the calendar. If your cap is gone, rainwater is entering the flue every time it storms, and a ten-minute visual check from the ground will tell you whether you need us out this week or can schedule comfortably. Call (762) 600-1468 and describe what you see; we’ll tell you straight if it can wait.

Chimney Liner Installation

Chimney Liner Installation (flue relining, in trade terms) means replacing the inner liner that channels smoke and combustion gases safely out of the house. In Alpharetta we see two main failure types: clay tile liners cracked from decades of heating cycles, and unlined chimneys in older 1970s and 1980s frames that were never built with one. A new liner installation in Alpharetta typically costs $2,000 to $4,500, and we use DuraFlex stainless steel systems because they’re built for continuous wood-burning loads. This is not cosmetic work; a failed liner lets carbon monoxide and heat reach combustible framing.

How we verify a liner has failed

Every liner quote from Flint Chimney Co Alpharetta starts with a camera scan. We run a video probe the full length of the flue and give you the footage, not just a verbal summary. You’ll see exactly what we see: gaping clay joints, missing tile sections, or rusted-through metal. If the liner is intact, we’ll tell you that too, and we won’t sell you a new one.

What the installation involves

We size the DuraFlex liner to your appliance and chimney dimensions, insulate it when required by the Georgia mechanical code for your setup, and connect it to the stove or fireplace with the correct termination. Most installations in Alpharetta, Johns Creek, and Roswell are completed in a single day. The liner is covered by the manufacturer’s warranty plus our written one-year guarantee, with a free return visit if anything we installed fails in that window.

Chimney Flashing Repair

Chimney Flashing Repair fixes the metal strips where your chimney meets the roofline, the place water most often enters an Alpharetta home. Flashing fails because the sealant dries out, the metal lifts in wind, or the original roofers used a single layer instead of the proper step-and-counter flashing system. Repairs in Alpharetta generally run $450 to $1,200 depending on how many sides of the chimney need attention and whether we can work from the roof safely. We inspect the flashing during every roof-adjacent chimney call and show you photos of exactly which joint is compromised.

The leak is rarely where the stain is

Water travels. A ceiling stain in a Sugar Hill or Mountain Park bedroom might trace back to a pinhole at the chimney corner, fifteen feet from where you see the damage. We trace the path with a hose test when needed and repair the actual source, not the symptom. That’s the difference between a $500 flashing repair and a $5,000 interior redo a year later.

Why we insist on step and counter flashing

Roof shingle overlaps and chimney mortar both expand and contract at different rates. A single strip of metal can’t bridge that movement. We install step flashing up the chimney sides, counter flashing cut into the mortar joint, and a soldered saddle on the uphill side when the chimney is wider than thirty inches. The written price covers every layer, and the repair carries the full one-year guarantee.

Chimney Crown Repair

Chimney Crown Repair restores the concrete or mortar slab that caps the chimney’s masonry top and deflects water away from the flue. In Alpharetta we see crowns cracked, spalled, or built wrong from day one, especially on homes where the original crown was made from plain mortar instead of Mortar Repointing with a proper mix. Repair costs in Alpharetta typically run $600 to $1,800 depending on whether we’re patching, resurfacing, or rebuilding the crown entirely. We use a flexible crown coat system that moves with the chimney instead of cracking again in three years.

Why North Georgia winters destroy crowns

Water seeps into hairline cracks, then freezes and expands. One winter with thirty freeze-thaw cycles in Roswell or Milton can turn a hairline into a wide fracture. The damage shows up first as efflorescence, that white chalky powder on the brick below. By the time you see the powder, water has been getting into the masonry for at least a season.

Patch versus full rebuild

We’ll always show you the camera or photo evidence before recommending a full rebuild. A minor surface crack might genuinely need only a trowel-grade fill and crown coat. A crown that’s separated from the flue tile or has loose chunks needs to be re-formed. Hank Delano quotes every crown repair with the exact scope specified so you know which one you’re approving.

Chimney Repair Companies

Chimney Repair Companies in Alpharetta vary widely in what they actually do, how they price it, and whether they stand behind their work. Some run a sweep-only operation and subcontract repairs out. Others pressure you into liner replacements you don’t need. Flint Chimney Co Alpharetta does the repair ourselves, with our own uniformed crews, puts the price in writing before any work starts, and covers every repair with a written one-year guarantee. Our Alpharetta repair work starts around $350 for smaller items like a cap replacement and runs to roughly $4,500 for a full liner installation.

What separates a legitimate shop

Ask any chimney company in Alpharetta, Cumming, or Lawrenceville three questions: Do you carry workers’ compensation for the crew on my roof? Do you provide a written guarantee covering workmanship for a full year? Will you show me camera footage of the defect before asking me to spend money? We answer yes, yes, and yes, and we’ll put all three in the written estimate.

Why the Garrison Standard matters here

Every Garrison Partners location operates under the same code: written price before work, background-checked uniformed techs, documented findings, and a free return visit if a covered repair fails within the guarantee period. You’ll hear it called the Garrison Standard. It’s not marketing language; it’s the operating rules we work under in Alpharetta and every other market we serve.

Chimney Masonry Repair

Chimney Masonry Repair covers the brick, block, and stone work of the chimney itself: repointing crumbling mortar joints, replacing spalled or cracked bricks, rebuilding the smoke chamber, or restoring the firebox. In Alpharetta, the freeze-thaw action on north-facing chimneys in Milton and Johns Creek means mortar starts failing after fifteen to twenty years, sometimes sooner if the original build was sloppy. Masonry repair in Alpharetta typically costs $800 to $2,500 per chimney depending on how many bricks need replacing and where the damage sits. We match mortar composition and brick color so the repair doesn’t look like a patch.

Repointing versus replacement

Repointing (tuckpointing) means grinding out cracked, crumbling mortar and packing fresh mortar into the joints. It fixes water entry and structural looseness without replacing a single brick. We reach for repointing first whenever the bricks themselves are still sound. If a brick face has popped off or the corners are rounded from water erosion, those units get replaced individually with matched stock.

What improper masonry work looks like

We’ve torn out countless previous repairs in Alpharetta, Stone Mountain, and Duluth where someone used Type S or Portland-heavy mortar on old brick, which locks moisture in and blows the brick face off within a few years. Historic and mid-century Alpharetta brick was fired softer and needs a lime-based mortar that breathes. This is the kind of thing that only shows up after five years, which is why our one-year guarantee is just the floor, not the ceiling.

Brands We Service

We install and repair DuraFlex liner systems more than any other product in Alpharetta, because their stainless steel alloy handles continuous wood heat without warping and the component fit is consistent. We’ve run hundreds of DuraFlex installations in homes from Roswell to Norcross, and our crews are factory-trained on their fitting and insulation requirements. When the liner has to be right and the stove runs hot, DuraFlex is what we specify on the written quote.

We also work with HeatShield for resurfacing old clay tile flues when a full liner isn’t warranted, and we stock Gelco, Olympia Chimney, Famco, and Copperfield components for caps, dampers, and terminations. If your chimney has a brand we didn’t name here, that doesn’t matter. The repair is what matters. We’ll source the right parts for your setup, and we’ll name them on the invoice.

Signs You Need a Pro Right Now

• Water staining on the ceiling or walls near the fireplace. This usually means the flashing, crown, or cap has failed and water is running down the chimney chase. By the time you see the stain in Alpharetta, the framing behind it has been wet for a while. Every day of delay invites mold and rot.
• Crumbling mortar or spalling brick on the chimney exterior. Loose mortar joints are open channels for water, and spalled brick faces mean freeze damage is already inside the masonry. You’ll see brick chips on the roof or ground, and white powder on the brick face. A structural mason can stop it before a section of the chimney needs rebuilding.
• A damp, smoky smell coming from the firebox, especially after rain. That’s water pooling in the smoke chamber or mixing with old creosote. The smell gets worse in humid months. It means water entry is active, and the fix is usually at the top of the chimney, not inside the firebox.
• You hear animals, or see nesting material falling into the fireplace. Squirrels, raccoons, and birds enter through an uncapped or badly capped flue. Their nesting material can ignite, and raccoons are now in your chimney, which is a problem that gets more expensive the longer you wait. A proper cap ends it.
• White smoke backing up into the room instead of drawing upward. This signals a draft problem: a blocked flue, a broken damper, or a liner that’s partially collapsed. Any of those is a fire or carbon monoxide risk. Stop using the fireplace and call. We’ll diagnose it with a camera before recommending anything.

Our Process, Step by Step

1. 1
   You call, a live person answers. We don’t route Alpharetta calls through a voicemail tree. A real person picks up 24/7, takes down what you’re seeing, and schedules a window that works. If it sounds urgent, we tell you whether to stop using the fireplace immediately.
2. 2
   We arrive, uniformed, background-checked, on time. Hank Delano’s crew shows up in a marked vehicle with a uniform you can’t fake. They’ll introduce themselves, put down drop cloths before any interior work, and explain what they’re checking before they go on the roof or into the firebox.
3. 3
   We inspect and document with camera and photo evidence. Every repair starts with a visual inspection, and most include a camera scan of the flue interior. You get the photos and footage, not just a verbal summary. If we find multiple issues, we prioritize them by safety, not by price.
4. 4
   You approve a written price, not a verbal ballpark. The quote lists each repair line by line: the materials, the labor, the scope, and the guarantee terms. The number on the invoice at the end is the number you approved before the first tool came off the truck. No change orders, no surprises.
5. 5
   We do the work, clean up, and hand you the guarantee. Repairs are completed the same visit whenever parts and materials allow. We sweep the work area, remove all debris, and give you a written repair report with the one-year guarantee in plain language. If a covered repair fails inside the year, we return at no charge.
