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 Fresno Guarantee
We started Alcott Chimney Fresno in 2002, and we’ve spent more than two decades learning what Fresno homeowners actually need from a chimney company: a clean, safe fireplace and the peace of mind that comes from knowing exactly who’s in your home and what you’re paying for. Our guarantee puts that in writing before we start. Every chimney sweep, inspection, and gas fireplace repair comes with a written price upfront, a written guarantee on every repair, and a free return visit if that repair fails. You’ll never sign off on work you didn’t agree to. That’s not a marketing line. It’s how Ruben Castellano operates every job, and it’s why we’ve stayed in business in the Central Valley for over two decades.
What’s Covered
Here’s exactly what we stand behind, in plain language, before any work begins.
- Workmanship on every repair. If the repair we make fails within the coverage period stated on your written guarantee, the second visit is free. No diagnostic fee, no labor charge, no argument.
- Parts and materials we install. We use professional trade brands like DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, and we handle warranty claims with manufacturers directly if a part fails. You won’t be shuffled between a supplier and a contractor.
- Cleanup after every job. We lay drop cloths, we vacuum the firebox and hearth, and we haul away the creosote and debris we remove. When we leave, your living room looks like we were never there, except your chimney is clean.
- On-time arrival, communicated clearly. You’ll know your technician’s name and see their photo before we arrive. When they ring the bell, they’ll show a photo ID badge. Every Alcott technician passes a background check and identity verification before they ever step on your property. That’s the Threshold Standard, and it’s not optional.
- Honest pricing with zero surprises. You receive a written price before work starts, every time. No “by the way” additions at the end, no pressure to authorize extras you didn’t see coming. If we find something during an inspection, we show you the camera footage and let you decide.

Our Satisfaction Promise
If something isn’t right, you call us, and we make it right. That’s the whole promise. We don’t bury the process in fine print or route you to a call center that promises a callback in three to five business days. A live person answers our phone around the clock, including at 11 p.m. when something smells like smoke and you’re not sure whether to go back to sleep.
For workmanship issues, the written guarantee on your repair tells you exactly what’s covered and for how long. Within that coverage period, if the repair fails, the second visit is free, full stop. We stand behind our installs for a full year through the 365-Day Done Right Promise, which gives you a full year of accountability on every completed job. If you’re unhappy with how a sweep went, tell us. We’ll come back and make it right. Ruben Castellano has built this company on repeat customers and referrals from neighbors in Fresno, Clovis, and the surrounding foothill communities. A homeowner who feels burned once never calls back, and that’s not a trade we’re willing to make.

AfterLicensed & Insured Backing
Licensing and insurance aren’t paperwork theater. They’re the reason you can hand your house keys to a technician without a knot in your stomach. Alcott Chimney Fresno is fully licensed and insured, and every technician is background-checked and identity-verified before they’re ever dispatched to a Fresno home. If a mistake happens, our insurance is there to cover it, not your homeowner’s policy. We carry the coverage because chimney work happens on ladders, on roofs, and around live fireplaces, and a responsible company doesn’t ask you to absorb that risk. When a technician shows up at your door in Fresno or Clovis, they’re uniformed, they’ve been vetted through the Threshold Standard, and they’ll show you a photo ID badge before they step inside. That’s the real guarantee behind the paperwork: a person you can vet, with a company that’s accountable.
Why This Matters for Fresno Homeowners
Fresno’s climate puts specific strain on chimneys. We get cold winter mornings where the fireplace runs every night for months, and we get long, dry summers where the heat bakes creosote deposits until they harden and glaze. A chimney that worked fine in March can be a fire hazard by November. The guarantee we offer isn’t a sales pitch; it’s the practical reality of maintaining a wood-burning fireplace in the San Joaquin Valley. You should know exactly what a sweep costs (a standard chimney sweep in Fresno typically runs $180 to $340 before any repairs), what your inspection found, and whether the fix is urgent or can safely wait. You should see the creosote, the glazing, the spalling brick, with your own eyes on our camera feed. And when a repair is needed, you should have it in writing what we’re going to do, what it costs, and what happens if it doesn’t hold.
Frequently Asked Questions
The written guarantee applies to our repair workmanship. It states exactly what was repaired, the coverage period, and what happens if the repair fails, which is a free second visit. We install professional trade materials like DuraFlex liners and HeatShield resurfacing, and manufacturer warranties on those materials are handled by us on your behalf. Call (559) 215-1714 and we’ll walk you through the specifics for your job before we begin.
The 365-Day Done Right Promise covers every completed job for a full year from the date of service. If anything we did isn’t right within that year, we come back and make it right. It’s not a re-sweep discount or a pro-rated credit. It’s accountability, in writing, for twelve months. Call (559) 215-1714 for details.
Call us. A live person answers at any hour. We’ll send a supervisor to your home in Fresno to see the issue ourselves, and we’ll make it right. This isn’t a situation where you fill out a web form and hope for the best. Ruben Castellano takes these calls seriously because his name is on the truck.
No. Gas fireplace repair carries the same written guarantee on workmanship and the same 365-Day Done Right Promise as everything else we do. The parts and brands we service, including Olympia Chimney, Famco, and Copperfield components, are handled through the same process: written price first, written guarantee on the repair, free second visit if it fails. Call (559) 215-1714 to talk through your specific gas fireplace.
We’re fully licensed and insured to operate as a chimney service company. We carry coverage because we work on roofs, around gas lines, and inside active flue systems, and if something goes wrong, you shouldn’t have to fight your homeowner’s insurance. Beyond that, every technician is background-checked and identity-verified through the Threshold Standard before they ever knock on a door in Fresno. You’ll see their photo before we arrive, and they’ll show ID at the door.
