Mortar Repointing in Marietta, GA

Mortar Repointing in Marietta, GA

Mortar repointing in Marietta typically costs between $800 and $2,500 depending on how much of the chimney’s mortar joints need work, and most jobs can be completed in one day. Repointing means removing cracked, crumbling, or missing mortar from between the bricks and replacing it with fresh mortar that matches your chimney’s original strength and look. If you’ve noticed sandy grit falling from your chimney or gaps opening between bricks, call Ashby Chimney Marietta at (478) 796-8742 for a written quote before any work starts.

We’ve been repointing chimneys around Marietta since 2002, and we’ve seen what Georgia’s wet winters and hot summers do to mortar over time. Our home base is right here in Marietta, and our technicians live in the same neighborhoods you do. This page is part of our broader Chimney Repair services, and we’ve written it so you know exactly what repointing involves, what it costs, and what we do differently from contractors who treat your chimney like an afterthought.

This work matters more than most people realize. Mortar is the glue that holds your chimney together, and when it fails, water gets in. That water freezes, expands, and pushes bricks loose. Left alone long enough, a chimney with failing mortar becomes a structural problem, not a cosmetic one. In Marietta, where we get those hard winter frosts followed by spring rain, the cycle hits chimneys hard. That’s why Nathan Corliss, owner of Ashby Chimney Marietta, insists on using mortar that’s actually suited to this climate and this chimney’s age, not whatever mix happens to be cheapest.

Key Takeaways:

• Mortar repointing in Marietta usually runs $800 to $2,500, with a written quote before any work begins.
• Cracked or missing mortar lets water into your chimney, and freeze-thaw cycles in Georgia winters make it worse fast.
• We complete most repointing jobs in a single day, often in under six hours.
• Every repointing job includes a written guarantee, and if the repair fails inside the guarantee period, we return and fix it at no charge.
• Phones are answered by a live person 24/7 at (478) 796-8742.

When You Need Mortar Repointing

Here’s the honest answer: if you can see crumbling mortar, you already need repointing. The question isn’t whether it’s happening. It’s how far it’s spread and how much brick you’ll need to reset. These are the signs we tell Marietta homeowners to watch for:

• Sandy grit at the base of your chimney or on the roof. This is dissolved mortar washing down. In older neighborhoods like Whitlock Avenue or around the Square, chimneys from the 1950s and 60s shed mortar like this constantly. Rain hits the chimney, absorbs into the soft mortar, and carries it down as grit.
• Visible cracks running through the mortar joints, especially horizontal ones. Horizontal cracks matter more than vertical hairline stuff. They usually mean the mortar has lost its bond and the bricks are starting to shift. If you spot these from your driveway or backyard, call us before the next hard rain.
• Gaps where mortar used to be. In East Cobb and Sandy Plains, we regularly see chimneys where entire joints have simply disappeared. Birds sometimes nest in the gaps. Water definitely gets in. This is a structural problem now, not a maintenance item.
• White powdery staining on the brick face. That’s efflorescence, and it’s the chimney’s way of telling you water is moving through the masonry. In Marietta’s humid summers, efflorescence shows up fast once water breaches the outer mortar layer.
• Bricks that wiggle or sound hollow when tapped. We don’t expect you to climb up and tap bricks, but if a brick comes loose on the ground or you can see one shifted out of line, the mortar holding it is gone. Call us. We’ll assess the whole chimney, not just the one brick.
• Water stains on interior walls near the fireplace. In homes off Lower Roswell Road and along Powers Ferry, water from a failing chimney cap and deteriorating mortar works its way into the wall cavity. You’ll see brown stains above the mantel or around the firebox. The chimney is the most likely source.

None of these are problems that fix themselves. Mortar doesn’t heal, and Georgia weather doesn’t give chimneys a break. The longer the gaps stay open, the more brick you’ll eventually need to remove and reset. We’d rather repoint a chimney when it needs 30 joints redone than rebuild it three years later because water kept getting in.

Our Mortar Repointing Process

Here’s exactly how we handle repointing, step by step. We don’t hide any part of this process. If you want to watch, you can. If you want photos, we’ll take them.

1. Inspection and written quote. We start by examining the chimney from the roof and the ground. We check mortar condition, brick condition, the crown, the cap, and the flashing. Then we write down a price. That price covers exactly what we’re going to do, and it doesn’t change unless we find something genuinely unexpected and get your approval in writing first. This is the written price promise we’ve made since 2002, and it’s the same promise every job gets.
2. Mortar matching. Old brick chimneys in Marietta were built with lime-based mortar, not modern Portland cement. Portland is too hard and too rigid for those old bricks. When the brick expands and contracts with heat and cold, hard mortar forces the brick to crack instead. We match the mortar to your chimney’s age and brick type. For chimneys from the 1960s and earlier, that usually means a lime-heavy mix that breathes with the brick.
3. Joint preparation. We grind or chisel out the damaged mortar to a depth that’s correct for the joint. For most residential chimneys, that’s between three-quarters and one full inch deep. We’re careful not to undercut the brick, and we don’t leave shallow joints that’ll fail again in two years. This is the slow part of the job, and it’s the part that separates a repointing job that lasts 30 years from one that lasts three.
4. Repointing the joints. We pack fresh mortar into each joint in layers, not one big smear. Packing in lifts lets each layer compact properly so the joint is dense and water-resistant. We tool the surface to match the original joint profile on your chimney, whether that’s a concave, flush, or weathered finish. This matters for looks as much as for water shedding.
5. Cleanup and final check. We wash down the work area, including any mortar smears on the brick face. We walk the whole chimney one more time and check every joint we touched plus the ones around it. If we find anything else that needs attention, we tell you plainly and quote it separately. No surprises on the invoice.
6. Written guarantee. Before we leave, you get a written guarantee covering the repointing work. If a covered repair fails inside the guarantee period, we return and correct it at no charge. That’s the 365-Day Done Right Promise, and it’s the same backing every Ashby Chimney Marietta repair carries.

Mortar Repointing Pricing in Marietta

Most mortar repointing jobs on Marietta homes fall between $800 and $2,500. The spread comes down to three things: how many joints need work, how high the chimney is, and whether we need scaffolding or a lift to reach everything safely.

Here’s a breakdown of what you’re paying for when you get a repointing quote from us:

Scope of Work	Typical Range	What It Includes
Partial repointing (10-20 joints)	$800 – $1,300	Grinding out and repointing a localized section, usually on one side of the chimney. Common for chimneys where one face gets hammered by weather.
Full repointing (single-story chimney)	$1,200 – $1,800	All four sides of a standard above-roof chimney. Includes joint prep, mortar matching, tooling, and cleanup.
Full repointing (two-story or steep roof)	$1,800 – $2,500	Same full repointing work, plus staging or ladder access on a steep pitch. Two-story chimneys in East Cobb homes with high rooflines usually land here.
Crown repair alongside repointing	$400 – $900 additional	Often the crown is cracked too. We’ll quote this separately and only if it’s needed.

What we won’t do is give you a lowball number over the phone and then show up with a higher one. Ever. When you call (478) 796-8742, you’ll talk to a person, and we can usually get someone out to look at your chimney within a day or two. The quote is free, it’s in writing, and it covers the whole job.

A few things that affect your specific price beyond joint count: chimney height, roof steepness, accessibility from the ground, and whether we’re matching a specialty mortar. Older Marietta chimneys built with soft, handmade bricks sometimes need a custom mortar blend, and that adds a little to material cost. We’ll tell you upfront, with the number on the quote you sign before work starts.

Why Repointing Matters More in Marietta

Marietta’s weather punishes chimneys in a specific way. We get cold snaps in January and February where temperatures drop below freezing at night and warm up during the day. Water gets into cracked mortar, freezes overnight, and expands by about 9 percent. That expansion pushes the crack wider. Next rain, more water gets in. Repeat that for three or four winters and you’ve got joints that are completely open and bricks that are loose.

Then there’s the humidity. Marietta summers run hot and wet, and moisture works its way into any opening. Once it’s inside, it drips down the flue, stains the walls, and rots the framing around the chimney chase. We’ve pulled apart chimneys in West Cobb where the interior framing looked like it had been sitting in a creek. All because a few mortar joints were left open.

The fix that lasts is proper repointing with mortar that actually matches the chimney. That’s where a lot of handyman repair jobs go wrong. They use a bag of premixed mortar from the hardware store, trowel it over the old joints, and call it done. It looks fine for a season. Then it fails because the old mortar underneath was never removed, and the new mortar doesn’t bond properly to the soft, aged brick. What you get is the same problem, plus a layer of crust on top that hides it until the damage is worse.

We use mortar matched to the original, removed from the failed joints to the correct depth, and packed in lifts. We also use professional-grade materials from chimney-trade suppliers like Olympia Chimney and Famco when the job calls for them. This isn’t whatever was in the van. It’s the right material for the specific chimney, selected on site.

Repointing vs. Rebuild: What’s the Difference?

Repointing fixes the joints between bricks. A rebuild replaces the bricks themselves. If your chimney has four or five bricks that are cracked, spalling, or loose, repointing can often save the chimney without a full teardown. We’ll reset those bricks in fresh mortar while we’re at it.

But if large sections of brick are crumbling and the chimney leans visibly, repointing won’t fix the underlying problem. In those cases, we’ll tell you plainly that a partial or full rebuild is the right call, and we’ll show you exactly why with photos. We’d rather lose a repointing job than take your money for work that won’t hold. That’s how we’ve operated since 2002, and it’s why Marietta homeowners call us back when they buy a second house or recommend us to neighbors on their street.

When we do recommend repointing, we’re confident the chimney’s structure is sound and the brick is still doing its job. The joints are the issue, and we can fix those. If you’re not sure which situation you’re in, call (478) 796-8742 and we’ll assess it honestly.

What You Should Know Before Hiring Anyone

We know plenty of Marietta homeowners have been burned by chimney companies before. A technician who no-shows, a price that doubles at the door, a repair that fails by spring. That’s exactly who we’re not.

Here’s what to ask any company before you sign a repointing quote, and here’s what you’ll get from us:

• What mortar will you use, and why? The answer should reference the chimney’s age and brick type. If they say “standard mix” without asking about your chimney, walk away. We match mortar to the specific chimney on every job.
• Will the price be in writing before work starts? If they hesitate, that’s your answer. Every Ashby Chimney Marietta job gets a written price before any work begins, and the invoice matches the quote. No exceptions.
• What’s covered if the repair fails? You want a written guarantee, not a handshake. Our repointing work carries a written guarantee, and if a covered repair fails inside the guarantee period, we come back and fix it at no charge. It’s the 365-Day Done Right Promise, and it’s included with every job.
• Who am I letting into my home? Our technicians are background-checked and uniformed on every visit. You’ll know who’s showing up and that they’re actually from Ashby Chimney Marietta.
• Can I reach a person when I call? Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback forms, no waiting until Monday. Call (478) 796-8742 any time and you’ll get a person.

FAQs – Mortar Repointing

How much does mortar repointing cost in Marietta, GA?

Mortar repointing in Marietta typically costs between $800 and $2,500, with partial jobs on one side of a chimney starting around $800 and full repointing on a two-story chimney running up to $2,500. The exact price depends on how many joints need work, chimney height, and roof access. Call (478) 796-8742 for a free written quote on your specific chimney.

Can you repoint a chimney the same day?

Yes, most repointing jobs can be completed in a single day, usually within four to six hours depending on the scope. We come out first to assess the chimney and write a quote, then schedule the work so it’s done cleanly in one visit. Call (478) 796-8742 and we’ll give you a realistic timeline.

Is it cheaper to repoint or rebuild a chimney?

Repointing is significantly cheaper than a rebuild, usually about one-third to one-half the cost. If the brick structure is still sound, repointing fixes the joints and extends the chimney’s life for decades. If large sections of brick are crumbling or the chimney leans, a rebuild is the honest recommendation, and we’ll explain exactly why with photos.

How long does repointing last in the Marietta climate?

Properly done repointing with correctly matched mortar typically lasts 20 to 30 years in the Marietta climate, and sometimes longer with a sound crown and cap. The key is removing old mortar to the correct depth and using a mortar mix that matches the chimney’s age and brick type. Call (478) 796-8742 for an assessment, and we’ll tell you what your chimney specifically needs.

Do I need a chimney inspection before repointing?

We always inspect the chimney before repointing because the joints are only part of the structure. We check the crown, cap, flashing, and flue liner (the clay or steel tube that vents combustion gases out of your home) so we’re not fixing one problem while another one lets water in. The inspection is included when we come out for a repointing quote.

Can you match the original mortar color on my chimney?

Yes, we match the original mortar as closely as possible using pigment tinting and by studying the old mortar’s color, texture, and joint profile. We can’t guarantee a perfect invisible match decades after the original work, but we get it close enough that most homeowners can’t spot the repaired area from the ground. We’ll show you a sample before we start packing joints.

Is water getting in through the mortar really that bad?

Yes, water entering through failed mortar is one of the fastest ways to destroy a chimney. In Marietta, freeze-thaw cycles in winter push cracks wider every year, and humid summers keep moisture moving through the masonry. Water reaching the interior framing causes rot and staining that costs far more to fix than repointing early. Call (478) 796-8742 if you see grit, cracks, or white staining on your chimney.
