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.

AfterMortar Repointing in Alpharetta, GA
Mortar repointing is the process of removing deteriorated mortar from the joints between chimney bricks and packing fresh mortar back in – restoring the seal that keeps water, cold air, and combustion gases where they belong. In Alpharetta, most chimneys built before 2005 show measurable joint erosion by the time they hit 15 to 20 years old, and our Georgia clay-heavy soil shifts enough through freeze-thaw cycles that even newer masonry isn’t immune. A repointing job done correctly stops that erosion before it turns into spalling brick or a cracked flue liner – repairs that cost three to five times more.
If you’ve noticed white chalky stains on the chimney face (efflorescence), crumbling mortar at the base, or joints that look visibly recessed, those are the signs we look for on every inspection. Emberly Chimney Cleaners Alpharetta has documented those conditions on more than 38,000 chimneys since 2009, always with a camera scan and a written price before anyone touches a tool. We handle mortar repointing as part of our broader Chimney Repair in Alpharetta work, and you can reach a live person at (678) 679-0171 any time – day or night.
When You Need Mortar Repointing
Not every chimney needs repointing right now, but several conditions make it urgent. Here’s what we see in Alpharetta homes on a regular basis:
- Recessed or crumbling mortar joints. When you run a key or screwdriver along the joint and mortar crumbles out easily, the joint has lost its structural integrity. Water enters every time it rains, and Alpharetta averages roughly 56 inches of rain per year – that’s a lot of water cycling through a compromised joint.
- Efflorescence on the chimney face. That white, chalky residue is dissolved mineral salt that water carried out of the masonry as it passed through. It’s a reliable sign that water is moving through joints that should be sealed.
- Spalling brick faces. When mortar joints fail, water migrates behind the brick face. In North Fulton County winters, that water freezes, expands, and pops brick faces off – a process called spalling. Repointing the joints stops the cycle before replacement becomes the only option.
- Staining or moisture inside the firebox. Homeowners in Windward, Crabapple, and Milton Road corridors frequently call us about rust stains or wet spots inside the firebox after heavy rain. Failed mortar joints at or above the roofline are a common cause.
- A chimney that’s never been inspected since purchase. If you bought a home between 2015 and 2025 in Alpharetta and haven’t had a Level 2 inspection with a camera down the flue, there’s a good chance joint erosion has been quietly progressing. Sellers rarely disclose it because most don’t know.
- Visible gaps at the crown-to-brick transition. The mortar crown sits at the top of the chimney and bears the worst of the weather. Cracks at the joint between crown and brick are a separate problem from crown repair, but they accelerate joint erosion on every course below.
Our Mortar Repointing Process
We don’t grout over old mortar. That’s a patch job that fails within two to three seasons. Proper repointing means removing the old material to a specific depth and replacing it with mortar that matches the original in composition and flexibility. Here’s exactly how we do it:
- Level 2 camera inspection first. Before quoting repointing, we run a camera down the flue and document every visible condition – joint depth, brick face integrity, crown condition, flashing seals. This isn’t optional prep work; it’s Clause 4 of the Haven Standard, and it means you get a photo record of exactly what existed before we started. We use NFPA 211 Level 2 protocol on every visit, which is the standard insurers and real estate attorneys actually rely on.
- Written scope and price delivered before work starts. Once we’ve reviewed the camera footage and assessed the extent of joint erosion, we give you a written price with a documented scope – which courses need repointing, the linear footage involved, and the mortar specification we’ll use. Haven Standard Clause 1 requires it: a written price, written scope, and written warranty before anyone starts work. No surprises after we’re already on the scaffold.
- Mechanical removal of deteriorated mortar. We use angle grinders with masonry wheels and, where access is tight, oscillating tools to cut out failed mortar to a minimum depth of 3/4 inch – typically closer to 1 inch on Alpharetta chimneys where clay soil movement has caused repeat cracking. Shallow removal is the number one cause of repointing failure, so we measure as we go.
- Joint cleaning and surface preparation. After mechanical removal, we blow out joint dust and debris with compressed air and wet the joint edges lightly before packing. Dry masonry pulls moisture out of fresh mortar too fast, which weakens the cure. This step gets skipped by a lot of contractors; we don’t skip it.
- Mortar packing and tooling to match the original profile. We match mortar composition to the original mix – lime content, sand grade, and Portland cement ratio – because using a too-hard mortar on older brick causes the brick face to crack instead of the joint, which is the exact opposite of what the joint is designed to do. We tool the joint to match the existing profile (concave, flush, or weathered) so the repair is both functional and visually consistent.
- Final photo documentation and written warranty delivery. When the work is complete, we photograph every repaired section and add it to your job’s documented record. You get that record. The 365-Day Done Right Promise covers every repointing job: if it fails within a year due to workmanship, we make it right at no charge.
BeforeAfterMortar Repointing Pricing in Alpharetta
Mortar repointing in Alpharetta typically runs between $400 and $1,800 depending on the chimney’s height, the number of courses requiring repointing, and whether the scaffold setup is straightforward or complicated by a steep roofline. How Much Does Chimney Repair Cost? (2026 Price Guide) - Alpharetta, GA Here’s a more specific breakdown of what drives cost:
- Spot repointing (2-6 linear feet of joints, one elevation): $400 – $650. Common on chimneys in newer Windward and Avalon-area subdivisions where only the upper courses near the crown show joint erosion.
- Partial repointing (one full chimney face or two elevations): $650 – $1,100. This is the most common scope we quote in Alpharetta on homes built in the 1990s and early 2000s.
- Full repointing (all four elevations, full chimney height): $1,100 – $1,800. Typically needed on chimneys that have been neglected for 20-plus years or where water infiltration has been active long enough to work through all faces.
- Scaffold or lift surcharge: $150 – $300 for chimneys on steep-pitch roofs or those requiring extended reach above 30 feet.
These ranges reflect current Alpharetta market pricing for professional work with proper mortar removal depth and matched mortar composition. Bids that come in significantly below the low end of these ranges almost always involve surface grouting over old mortar – a fix that typically fails within 24 months.
The Level 2 camera inspection that precedes any repointing quote is included as part of the scoping process. You get a written price with a fixed scope before work begins – not a ballpark figure that grows once we’re already on the roof. Call (678) 679-0171 to schedule; estimates are free and written, and we’ll have a named technician assigned before the appointment.
If you have a written quote from another company, bring it to us. We offer a free second opinion on any written estimate – no obligation, just an honest read on whether the scope is right and whether the price is fair for the Alpharetta market.
Why Alpharetta Chimneys Erode Faster Than You’d Expect
This is something we document consistently in our inspection records, so it’s worth explaining clearly. Alpharetta sits in a transition zone where winter temperatures drop below freezing often enough to drive freeze-thaw cycling in masonry – typically 30 to 50 freeze-thaw events per year in a normal North Fulton winter – but rarely cold enough to justify the high-lime mortar formulations common in the Midwest and Northeast. A lot of Alpharetta chimneys built in the 1990s construction boom were mortared with mixes that perform fine in truly cold climates but erode quickly under Georgia’s wet-freeze-thaw-wet pattern.
Add to that the fact that many chimneys in the Crabapple historic district and older sections of downtown Alpharetta used a softer, high-lime mortar appropriate for the era – which is actually correct for those older bricks but fails badly if a contractor replaces it with modern Portland-heavy mix. We see this mistake regularly: a well-intentioned repointing job done with the wrong mortar spec that ends up cracking the brick face rather than the joint. The joint is supposed to be the sacrificial element. When you use mortar that’s harder than the brick, you lose the brick instead.
We source mortar materials through our supply network, which includes Olympia Chimney and Copperfield, specifically because their product lines allow us to dial in the lime-to-Portland ratio for each chimney’s age and original brick type. That specificity is what makes the difference between a repointing job that lasts and one that has to be redone in three years.
Mortar Repointing vs. Chimney Repair: How They Fit Together
Repointing is one piece of our Chimney Repair services. When we inspect a chimney and find joint erosion, we also check the crown for cracking, the flashing for separation at the roof deck, and the flue liner for evidence of water infiltration. Those are separate line items, but they’re related – a failed crown accelerates joint erosion, and failed joints accelerate liner damage.
Our Chimney Repair in Alpharetta page covers the full range of masonry and liner work we do. If repointing is the right scope, we’ll say so and price it clearly. If the inspection shows the chimney needs more, we’ll document exactly what we found – with photos – and let you decide what to address first. That’s the only way to run an honest repair business, and it’s how we’ve operated since we started under the Emberly Chimney Cleaners framework in 2009.

FAQs – Mortar Repointing in Alpharetta
How much does mortar repointing cost in Alpharetta, GA?
Mortar repointing in Alpharetta runs $400 to $1,800 for most residential chimneys, with partial repointing of one or two elevations landing in the $650 to $1,100 range most often. The main cost variables are how many faces need repointing, the chimney’s height, and whether scaffold or extended lift access is required on steep rooflines. Every quote we provide is written and fixed before work starts – call (678) 679-0171 for a free estimate with a specific number, not a range.
How do I know if my chimney needs repointing or full brick replacement?
Repointing is the right repair when the brick faces themselves are structurally sound but the mortar joints are recessed, crumbling, or absent. Replacement becomes necessary when the brick faces are spalling (popping off) deeply enough that the structural integrity of the brick unit itself is compromised. The honest way to make that call is with a camera inspection that lets you see how deep the damage runs – not a visual from the ground or a ladder. We document that finding in writing before recommending any scope of work.
Can I repoint chimney mortar myself?
The mechanical work of repointing – grinding out old mortar and packing new mortar in – is physically demanding but not inherently dangerous the way spring replacement or electrical work is. The real risk is getting the mortar specification wrong. Using a mortar mix that’s harder than your brick will cause the brick faces to crack over the following two to three winters, turning a $600 repair into a $3,000 brick replacement. If you want to tackle spot repointing yourself, match the mortar type to your brick age: pre-1950 brick typically needs a Type O or Type K mix (high lime, low Portland); post-1970 brick can usually accept Type S. For anything above two courses on a roofline, the fall risk alone warrants calling a professional.
How long does mortar repointing last?
A properly done repointing job – correct mortar spec, full removal depth, matched joint profile – should last 20 to 30 years on an Alpharetta chimney. The most common reason repointing fails early is surface grouting over old mortar rather than mechanical removal, or a mortar mix that doesn’t flex with the chimney’s seasonal movement. Our jobs are covered by the 365-Day Done Right Promise, but the workmanship standard we hold ourselves to is designed to hold well past that first year.
