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 Alcott Chimney Marietta Guarantee
We’ve been cleaning and repairing chimneys in Marietta since 2002, and for more than two decades the rule hasn’t changed: if the work isn’t right, we make it right. That’s not marketing language. It’s the only way a chimney company in Cobb County stays in business year after year. Every job we complete, from a standard sweep off Canton Road to a full liner installation near the Square, ends the same way. You get a written price before we start, a written guarantee on every repair, and a full year of accountability through our 365-Day Done Right Promise. If a repair fails during that coverage period, the second visit is free. Full stop. We don’t ask questions, we don’t charge a trip fee, and we don’t make you chase us. Ruben Castellano, our owner, has built Alcott Chimney Marietta around a simple idea: homeowners in Marietta should never have to gamble on whether a chimney company will stand behind its work.
What’s Covered
- Workmanship on every sweep and inspection. If we miss a section of creosote or overlook a problem that a competent chimney professional should have caught, we’ll come back and redo the work at no charge.
- Every repair, backed in writing. From a new damper plate to a full DuraFlex stainless liner installation, you receive a written guarantee before the job starts, and if the repair fails within the coverage period, the second visit is free.
- Parts and materials we install. We use professional trade brands including HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, which means the products themselves carry manufacturer warranties that we handle the paperwork on, so you don’t have to.
- Cleanup and property protection. Drop cloths go down before any work begins, HEPA vacuums stay running during the sweep, and we leave your hearth and floors as clean as we found them. If we don’t, you’ll hear from us with an apology and a fix.
- On-time arrival, or a call. When we schedule a sweep in East Cobb or Kennesaw, we show up in the window we gave you. Traffic on I-75 happens, but silence doesn’t. You’ll get a call if we’re running behind.
- Honest pricing, in advance. The written price we hand you before work begins is the price you pay. No add-ons discovered at the end, no “while we were in there” surprises. If the scope needs to change, we stop, explain, and get your sign-off first.
- The technician at your door. Every Alcott technician is background-checked and identity-verified through the Threshold Standard. You receive the technician’s name and photo before the visit, and they’re required to show a photo ID badge at the door. Every time, no exceptions.

Our Satisfaction Promise
Here’s what happens if you’re not satisfied with any part of the work. You call (229) 350-8952, you tell a live person what’s wrong, and we schedule a return visit. There’s no phone tree, no voicemail queue, and no “we’ll get back to you within 72 hours.” Someone answers, every time. On the return visit, we look at the concern together, we show you what happened, and we fix it. If the issue falls under our repair guarantee, you pay nothing. If it’s something we should have caught during an inspection, you pay nothing. If we made a mess or scratched a hearth brick, we own it and make it right. The 365-Day Done Right Promise covers a full year on every completed job, which is more than long enough to run a full burning season in Marietta, from the first cold snap in October through the mild days of a Georgia spring. And if we’re wrong about something, you’ll hear us say so. That’s the standard Ruben Castellano set when he joined the Threshold Group family of home-service companies, and it’s the standard every Marietta homeowner gets, whether the job is a $200 sweep or a multi-thousand-dollar liner system.

AfterLicensed & Insured Backing
Paperwork matters. Any company can promise to fix its mistakes, but the promise only has teeth if the company is still around to honor it. Alcott Chimney Marietta is licensed and insured & bonded, and that’s the real guarantee sitting behind everything we put in writing. If a technician gets hurt on your property, our insurance covers it, not your homeowner’s policy. If something goes wrong during a job, our bond is there to make you whole. And because Ruben Castellano operates Alcott as an independently owned and operated location within the Threshold Group family, every claim is handled through a structured accountability process, not a handshake. Our technicians are background-checked and identity-verified through the Threshold Standard before they ever set foot on a Marietta property, and they arrive uniformed, announced by name and photo, and prepared to show a photo ID badge at the door. That’s the kind of vetting that gives a guarantee weight. You know who’s in your home, and we know exactly who represents this company.
Common Questions About Our Guarantee
What does the guarantee actually cover?
Every repair we perform carries a written guarantee. If that repair fails during the coverage period, the second visit and the second repair are free. We also stand behind the quality of every sweep and inspection. If we missed creosote buildup that should have been removed, or overlooked an issue a qualified chimney professional should have flagged, we’ll return and make it right at no charge. The specific coverage period is written on your estimate before work begins, which is exactly what the 365-Day Done Right Promise is built around: a full year of accountability on every completed job. Call (229) 350-8952 if you have questions about a current or past job.
How long is the warranty on a new liner or repair?
The exact duration depends on the product and the scope of the installation, and it’s written on your estimate before any work starts. What doesn’t change is this: every repair we touch carries a written guarantee, and if it fails within the coverage period, the second visit is free. We install DuraFlex liner systems, HeatShield resurfacing, and components from Copperfield and Olympia Chimney, which are materials chimney professionals specify specifically because they’re built to last. When we install them, we handle the paperwork and stand behind the installation. For an exact quote on your Marietta home, call (229) 350-8952 and we’ll walk you through it.
What if I find a problem after you leave?
Call the number. A live person answers. You describe the issue, we schedule a return visit, and we’ll show up ready to look at it with you. If it’s covered by our guarantee, you pay nothing. If it’s not a covered repair, we’ll show you exactly what we’re seeing and give you a written price before any additional work begins. No one at Alcott Chimney Marietta is going to tell you a problem exists without showing you the evidence. That’s the whole point of the name-and-photo preview before we arrive: you know who’s coming, and we know we’re accountable to you from the moment we knock on the door.
