Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
The Ashby Chimney Marietta Guarantee
Since 2002, we have built Ashby Chimney Marietta on a simple idea: a chimney company should put its promises in writing before the work starts, not after something goes wrong. When we sweep, inspect, or repair a fireplace in Marietta, GA, you get a written price before we touch a single brick, and a written guarantee on every repair when we finish. If a covered repair fails inside the guarantee period, we come back and fix it at no charge. That is the 365-Day Done Right Promise, and we do not sell it as an add-on. It is included, every time, no exceptions. Nathan Corliss, Owner, put this in place because he got tired of hearing stories about homeowners paying twice for the same repair.
What’s Covered
- Workmanship on every repair. If something we fixed fails because of how we fixed it, we return during the guarantee period and make it right at no charge.
- Parts and materials, handled properly. We source from established chimney-trade suppliers like DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, so repairs use materials made for chimneys, not whatever was in the van.
- Cleanup as part of the job. We lay down drop cloths, run a HEPA-filtered vacuum, and leave your hearth and floors the way we found them. If we forget a dust line, call us and we’ll come back.
- On-time arrival, in a real window. We schedule a window we can actually keep. If we’re running late, a live person calls you from our Marietta office, not a robot text from a call center.
- Honest pricing, in writing, before work starts. The price on your written quote is the price on your invoice. Flat. No surprise line items. No “while we were in there” upsells after the fact.

Our Satisfaction Promise
Here is how it works in Marietta. If you look at the finished job and something is not right, you tell us. We do not argue about whether you should have noticed it sooner. We schedule a return visit, take a look, and make it right. The 365-Day Done Right Promise is our version of a satisfaction guarantee, but it applies to the specific repair we performed, not the general state of a thirty-year-old chimney. We are honest about that distinction because it matters. If tree roots shifted your flue a year after we relined it, that is a new problem, and we will tell you so plainly. But if our repair failed, the fix is on us. Nathan would rather spend a Tuesday afternoon redoing a patch than have a neighbor in East Cobb or Smyrna tell someone Ashby walked away from a problem.
We also make a promise about what we will never do. We will never recommend a repair you cannot verify. Every chimney inspection from Ashby Chimney Marietta includes camera footage of the flue. If we say your flue liner, the clay or steel tube that vents combustion gases out of your home, needs replacement, you will see it with your own eyes. If we can show you a crack or a gap, you understand the cost. If we cannot show it to you, we do not ask you to pay for it.
Licensed & Insured Backing
Paperwork is not exciting, but it is the reason our guarantee means something. Ashby Chimney Marietta is a licensed and insured chimney contractor in Cobb County, which protects you two ways. If a technician is injured on your property, our insurance covers it, not your homeowner’s policy. If an accident damages your home, our insurance handles the claim. We also carry bonding coverage, which matters if a job goes sideways in a way nobody predicted. Anyone can print “guaranteed” on a business card. A written guarantee from a licensed and insured contractor is backed by a company that has to stand in front of a regulator and a claims adjuster if it breaks its word. We have been doing this in Marietta since 2002, and we intend to keep doing it for a long time.
The Kingswell Way
Ashby Chimney Marietta is independently owned and operated under the Kingswell Guarantee. That means we follow five rules on every visit, and we are specific about them. Say the price before any work starts, in writing. Show up inside the window we promised. Leave the home cleaner than we found it. Put every repair guarantee in writing. Come back at no charge if the repair fails inside the guarantee period. The Kingswell Way is not a loyalty program or a marketing slogan. It is a checklist our technicians carry on their clipboards, and the last item on it is the one that matters most.

AfterWhat Happens If a Repair Fails?
You call (478) 796-8742 and tell the live person who answers what you are seeing. We pull up your job record, confirm the repair date and what we did, and schedule a return visit at no charge. There is no deductible, no service fee, no “well, that part of the chimney was already weak” defense. If the repair we performed failed inside the guarantee period, we fix it. Nathan Corliss signs the guarantee on every repair personally because his name is on the line, and in Marietta, a reputation is the only thing that keeps the phone ringing come November.
What the Guarantee Does Not Cover
We are direct about this because vague guarantees make people suspicious. The written guarantee on your repair covers the specific repair we performed. It does not cover pre-existing conditions we documented and told you about, damage from a chimney fire, lightning strike, earthquake, or a tree falling on the cap, or new problems that develop in a different part of the chimney. If your crown cracks two years after we rebuilt the firebox, that is a new repair with a new written price. What it does cover is our workmanship on the repair we did, and we stand behind it with a free second visit if it fails.
Why This Matters in Marietta Specifically
Marietta’s climate is not kind to chimneys. The freeze-thaw cycles in January and February push water into hairline cracks and split them wide by March. The humidity from May through September keeps masonry damp for months. If a chimney company in Marietta will not put its repair guarantee in writing, that is a red flag, because this climate guarantees that bad work will fail within two years. We know. We have been called out to re-do plenty of it since 2002. The 365-Day Done Right Promise exists because Nathan got tired of looking at other contractors’ failed patches and thinking, “Someone charged eighteen hundred dollars for this and never came back.”
Questions Marietta Homeowners Ask Us
How long does the guarantee last?
Every repair from Ashby Chimney Marietta carries a written guarantee that we give you on completion. The specific length depends on the repair type, and it is printed on your paperwork before you sign anything. What does not vary is this: if a covered repair fails inside the guarantee period, we return and fix it at no charge. Call (478) 796-8742 and ask us to walk you through the guarantee terms for your specific chimney before you book. Our estimates are free, and the guarantee is included in the written price.
Do I have to register for the guarantee to apply?
No. The guarantee is included with every repair. There is no registration card, no warranty activation fee, no “premium plan” upgrade. That is the point of putting it in writing on the day of the job. Your copy is your proof. If your paperwork gets lost, call us. We keep job records.
What if I’m not happy with the cleanup?
Then you got a bad visit from us, and we’ll make it right. Cleanup is part of the job, not an optional extra. If we leave dust on your mantel or a footprint in the hallway, call (478) 796-8742 and tell us. We’ll come back and finish the job the way it should have been done the first time. The 365-Day Done Right Promise starts with the basic stuff, not just the structural repair.
What if I need to see proof of insurance before you start?
Ask us for a certificate of insurance. Any reputable chimney company in Marietta will provide one. We do it routinely for condo associations, property managers, and homeowners who have been burned before by uninsured contractors. It takes one phone call. If a company hesitates to show you insurance paperwork, that tells you something.
