Frequently Asked Questions - Chimney Cleaning in San Antonio, TX
Straight answers to the questions San Antonio homeowners ask us most, from pricing to what actually happens during a sweep. If you don't see your question here, call (903) 515-5079 and we'll talk it through.
Pricing & Cost FAQs
A standard chimney cleaning in San Antonio runs $169 to $289 for a single flue with an accessible roofline, while two-story homes and chimneys with heavy creosote buildup typically land between $250 and $400. The biggest variables are roof pitch, fireplace type, and whether animals have nested inside. We put every price in writing before any work starts, so there's no surprise line item. Call (903) 515-5079 and we'll give you a firm range for your specific setup before we book anything.
The difference almost always comes down to what's included. A lowball price often means a rush job: no camera inspection, no smoke guard, no cap check, no photo report afterward. Our pricing reflects the full service: a top-down cleaning, a camera scan of the flue, a written condition report with photos, and the brand's guarantee. You're paying for documentation, not just the brushing. In neighborhoods like Alamo Heights and Terrell Hills, multi-story rooflines also add legitimate labor time.
No. The cap, flashing, and accessible damper are included in the sweep inspection. If we spot a failing liner or rusted cap during the camera pass, we'll show you the footage and give you a separate written quote for the repair. You approve or decline, and there's no pressure either way. We'd rather you see the flue with your own eyes than take anyone's word on a five-thousand-dollar liner replacement.
Sometimes. Summer is our slower season in San Antonio because fireplaces sit dormant, so you'll occasionally find modest seasonal pricing or more flexible scheduling windows. But don't let price alone drive the decision. A discounted sweep that skips the camera inspection leaves you blind to the crack that starts this winter. Call (903) 515-5079 for current pricing and we'll tell you honestly whether waiting saves you anything meaningful.
Yes. We provide a free written estimate before any work begins, and on many standard single-story homes we can quote a firm price over the phone once we know your fireplace type and roof access. For unusual setups, like a chimney on a steep Boerne hillside lot or a zero-clearance fireplace with a factory pipe, we may need to see it in person first. Call (903) 515-5079 and describe what you've got.
Service & Process FAQs
We run brushes down the full length of the flue to knock creosote and soot off the walls, then collect everything at the fireplace opening, keeping your home clean. After the brushing, we run a camera through the flue to check for cracks, gaps in the mortar, or rust. You get a written report with photos and our recommendation. The whole process is built around one idea: nothing gets recommended unless we can show you the evidence on screen or in a photo.
Most cleanings take 60 to 90 minutes from setting up drop cloths to the final walkthrough. Heavier creosote buildup, bird nests, or a chimney that hasn't been cleaned in years can push that to two hours. We keep your floors covered, your furniture protected, and we clean up everything before we leave. If you're scheduling around work, plan for a two-hour window so no one feels rushed.
The National Fire Protection Association recommends cleaning whenever creosote deposits reach 1/8 inch or thicker, which for most San Antonio homeowners who burn regularly means once a year. If you only light a handful of fires per season, every two years may be enough, but the only way to know is to look. Our camera inspection tells you exactly how much buildup is in there, so you're not cleaning on a calendar guess. We'll tell you plainly when you can safely wait.
Creosote is the tar-like residue that condenses inside the flue when wood smoke cools before it exits the chimney. In San Antonio's humid climate, fires often burn cooler, especially during mild winter days when you're only lighting a fire for atmosphere, not heat. Those low, slow burns produce more creosote than a hot, roaring fire. Creosote is what makes chimney fires so dangerous: it's fuel, and it builds up in layers until there's enough to ignite.
Probably yes, at least once. Infrequent use doesn't prevent creosote; in San Antonio, occasional fires often burn cooler because people aren't managing a full fire cycle, and that produces more residue per burn. There's also the animal question: chimneys that sit unused become popular nesting spots for birds and squirrels. A cleaning plus camera inspection tells you both things at once. When it's been more than two years, give us a call at (903) 515-5079.
Yes. Our team works on San Antonio's tougher rooflines regularly: steep pitches in Boerne, older masonry chimneys in Alamo Heights, and second-story fireplaces in Terrell Hills. Roof pitch adds time and care to the job, and we price that honestly rather than pretending every chimney is the same. If your roofline gives you pause, call and describe it; we'll tell you what's involved before anyone climbs up there.
A zero-clearance fireplace is a factory-built metal firebox designed to sit close to framing, common in newer homes across Cibolo, Schertz, and Converse. Yes, we clean these, but they require a different approach than a masonry chimney: smaller brushes, careful handling of the factory flue pipe, and attention to the manufacturer's clearance requirements. We'll identify what you have and clean it appropriately, with the same camera inspection and photo report.
Brands & Parts FAQs
We install and repair liners from manufacturers we trust, including Copperfield and DuraFlex, both of which make stainless steel liners built for the long haul. When a liner needs repair rather than replacement, we also work with HeatShield, a cerfractory sealant system that can restore a damaged flue without tearing out the old one. We'll walk you through the options and the honest cost differences so you can choose with confidence.
We do. Famco makes rugged galvanized and stainless steel caps and dampers that hold up well in San Antonio's sun and humidity. The cap is your first defense against rain, animals, and downdrafts, so we inspect it on every visit and show you what condition it's in. If it's rusted through or missing, we'll give you a written price for a replacement before we do anything.
It depends on the condition of the existing flue. If the clay liner has minor gaps or cracks, HeatShield can often seal it for less than a full replacement. If the flue is severely deteriorated, a stainless liner from Copperfield or DuraFlex is the sturdier long-term fix. We'll show you camera footage of your flue and explain both options with pricing, so you're deciding based on evidence, not a sales pitch.
Licensing & Insurance FAQs
Every professional working under the Alcott name is required to hold the license and insurance their state mandates, and our San Antonio team operates under the brand's verification standards. You're welcome to ask about credentials when you book. What you won't have to ask about is who's coming to your door: we send the technician's name and photo before the visit, and they arrive in a clean, marked uniform with a photo ID badge.
It's called the Threshold Standard, and it's the reason the brand exists. Every technician is background-checked and identity-verified. We send you their name and photo before the appointment. They show a photo ID badge at the door, every time. They arrive in a clean, marked uniform. And the price goes in writing before any work starts. If someone shows up who you weren't told to expect, that visit is on us and we make it right.
Because you'll know who they are before they ever ring the bell. Opening the door to a stranger is a genuine worry, especially if you're home alone or managing young kids. The Threshold Standard was built for exactly that: you get the technician's name and photo in advance, they present a photo badge at the door, and they arrive in a marked uniform. It's not a courtesy gesture; it's the promise the entire brand is built on.
Emergency & Response FAQs
Get everyone out of the house and call 911 immediately. Do not try to put it out yourself, and do not climb onto the roof. After the fire department clears the scene, call us at (903) 515-5079 to schedule a full inspection before you use the fireplace again. A chimney fire can crack the flue liner in ways you can't see from the firebox, and the next fire could be the dangerous one.
We're open Monday through Friday from 7:00 AM to 7:00 PM and Sunday from 7:00 AM to 7:00 PM, closed Saturdays. If you've had a chimney fire or suspect damage, we'll get you scheduled during our open hours and make the inspection a priority. For active fires or carbon monoxide alarms, call 911 or your gas utility first, then reach us to handle the chimney itself.
Our schedule doesn't support same-day booking, but during the milder months we can often get you on the calendar within a few days. Burning season fills up faster, so if you're thinking about a cleaning before winter, call (903) 515-5079 early. We'll find you a time that works, and you'll know exactly who's coming and when.
Warranty & Guarantees FAQs
The brand's promise is the Threshold Verified guarantee: every technician you meet has been background-checked, identity-verified, photo-badged, and sent to you by name and photo before the visit. If anyone arrives who you were not told to expect, that visit is on us and we make it right. For the work itself, we stand behind the cleaning and the inspection findings, and we'll walk you through exactly what's covered in writing before we begin.
Tell us. We'd rather hear about it while we're still in your driveway than read about it later. If the cleaning isn't what you expected, we'll come back and make it right. That's not a scripted line; it's how a local San Antonio business keeps its reputation intact. Call (903) 515-5079 and talk to us directly about what went wrong.
A stainless steel liner from a manufacturer like Copperfield or DuraFlex typically carries a lifetime warranty from the manufacturer, and with proper cleaning and annual inspections, the liner itself can outlast the house. The key is the installation. A liner that's sized wrong or poorly connected fails early, which is why the camera inspection and a written condition report are part of every job we do.
The inspection is documentation, not a guess. You get photos and a written report of what we find, and we keep a copy so we can compare next year's condition to this year's. If we say a liner is cracked, you'll see the crack in the footage. If we say the flue is clean, you'll see that too. That's the whole point: evidence you can hold onto, and a record that makes next year's inspection meaningful.
Yes, and we'll be direct about it. After the cleaning and camera inspection, if your flue has only light soot and no structural concerns, we'll tell you it can wait. If there's a crack, a failing cap, or heavy creosote, we'll show you and explain why it shouldn't wait. The goal isn't to sell you a repair; it's to make sure you're using your fireplace safely in San Antonio's burning season. Call (903) 515-5079 and book an inspection, and you'll have your answer with evidence to back it.
