Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Trusted Chimney Sweep for Alamo Square Homeowners
A chimney sweep in Alamo Square typically costs $180 – $340 for a standard inspection and cleaning of a wood-burning fireplace, and most jobs take 60 – 90 minutes from setup to final vacuum. If you’ve noticed a smokey smell when the fireplace isn’t in use, visible soot falling into the firebox, or it’s simply been more than a year since your last cleaning, the fix usually starts with a thorough sweep and a camera inspection of the flue. Doug Lockhart and the team at Chimney Sweep Alamo Square handle this every day for homeowners across the neighborhood, from the Victorians along Hayes Street to the newer construction near the Panhandle. Call (833) 620-7061 to book an appointment, and we’ll give you a flat-price quote before any work begins.
Chimney Sweep Services
Chimney Sweep Services cover the full scope of flue cleaning, inspection, and maintenance for masonry and prefab chimneys, including wood-burning and gas units. You need this whenever creosote accumulates beyond a thin dusting, which for most Alamo Square homes that burn wood means once a year, or when you’ve moved into a new house and don’t know the chimney’s history. Our Chimney Sweep Maintenance Checklist for Alamo Square Homeowners can help you track when it’s time. Chimney Sweep Alamo Square brings professional-grade equipment and materials from trade brands like DuraFlex and Copperfield, so the work is done to specification, not improvised with whatever’s on the truck. A standard sweep and inspection runs $180 – $340 in this area, with repair findings quoted separately and only after you’ve seen the evidence on camera.
Flue Inspection and Camera Review
Every sweep starts with a camera run through the flue, top to bottom. We look for cracked tiles, deteriorated mortar joints, animal nests, and hidden creosote buildup that brushing alone won’t reveal. You see the footage yourself before we recommend anything.
Creosote and Soot Removal
Rotary brushes and professional vacuums remove the flammable deposits that collect on flue walls. The goal is not a cosmetic shine; it’s removing the fuel that feeds chimney fires. We contain the dust at the fireplace opening so your living room stays as clean as it started.

Chimney Cleaning
Chimney Cleaning is the physical removal of creosote, soot, and debris from the interior flue walls, a job that prevents chimney fires and keeps exhaust moving freely to the outside. Most homeowners schedule this annually in the fall, before the burning season starts, since creosote builds up fastest during regular winter use. Our crews at Chimney Sweep Alamo Square use professional vacuum systems with HEPA filtration and rotary brush heads sized to your flue, whether that’s a rectangular masonry tile liner or a round stainless system. For a standard one-story fireplace in the Alamo Square area, expect $180 – $300; a heavily glazed creosote condition or a second flue adds to the cost.
Rotary Brush Sweeping
The brush does the heavy lifting, but the technique matters. We match the brush diameter and stiffness to the flue dimensions, so we remove deposits without scoring the tile or scratching a metal liner. This is the default method for most residential masonry chimneys in Alamo Square.
HEPA Dust Containment
Sweeping generates fine particulate. Our vacuums run continuously during the process and we seal the firebox opening with a barrier before we start. When we leave, the soot goes with us, not into your carpet or curtains.
Fireplace Cleaning
Fireplace Cleaning addresses the firebox itself, where ash, charred wood, and the acidic residues from combustion sit against brick, stone, or refractory panels. You need it whenever ash builds up beyond an inch or so, when you smell last year’s fires on humid days, or when the firebox shows white staining from moisture mixing with creosote. Chimney Sweep Alamo Square cleans fireboxes as part of a full sweep; we remove old ash, brush down the firebrick, and inspect the mortar joints for cracks that let heat or sparks reach combustible framing. Plan on $180 – $340 for a bundled sweep and firebox cleaning in Alamo Square, with more for refractory panel replacement if that’s needed.
Firebox and Hearth Cleaning
We remove ash and debris from the firebox floor and vacuum the hearth area, including behind the damper where buildup hides. Then we inspect the firebrick for spalling or missing mortar, because that’s where heat can escape in ways you’ll never see from the living room.
Damper and Smoke Shelf Care
The damper and smoke shelf collect creosote and can seize open or shut over time. We clean both during a standard service and verify the damper opens and seals correctly. A stuck damper is a slow heat leak all winter long, and most homeowners never touch it between sweeps.
Chimney Services
Chimney Services is the umbrella term for anything a chimney needs beyond a standalone sweep: crown repair, flashing replacement, liner inspection and resurfacing, cap installation, and masonry pointing. Homeowners reach out to us when a sweep reveals damage, or when water is entering around the chimney, or when a home inspector flags the flue before a purchase. Because Chimney Sweep – Alamo Square has HeatShield certification and stocks DuraFlex liner systems, we can move from diagnosis to repair without referring you to a third contractor. Sweep-and-inspect work runs $180 – $340 in Alamo Square; repairs are quoted per project after a camera review, and nothing gets recommended without footage you can see.
Chimney Repair and Liner Work
HeatShield lets us resurface a deteriorated clay tile liner without tearing down the chimney, and DuraFlex gives us a code-approved flexible liner for full relining jobs. These are professional material lines, not what you’ll find at a hardware store on Divisadero.
Caps and Crown Work
Gelco chimney caps and proper crown sealing keep rain, birds, and debris out of the flue. We’ll tell you plainly if your existing cap is fine and the leak is coming from somewhere else; no one on our crew earns a commission for selling caps you don’t need.
Chimney Sweep Certified
Chimney Sweep Certified means the technician on your roof holds industry-recognized credentials for inspection, cleaning, and safety evaluation, not just a pickup truck and a brush. Certification matters because a missed crack in a flue liner is invisible without the training to look for it, and the stakes go beyond soot: carbon monoxide and fire both follow the path of least resistance. Doug Lockhart holds the certifications that matter for this trade and the company maintains HeatShield application training, which generalist handymen cannot access because the manufacturer restricts it. Certification adds no markup to a standard sweep in Alamo Square; you’re still looking at $180 – $340, but you’re getting an evaluation that catches what an untrained eye misses. If you’re curious what issues to watch for yourself, see our Chimney Sweep Troubleshooting: Common Problems and How to Fix Them.
Why Certification Changes What You’re Told
A certified sweep knows what a flue clearance violation looks like because they’ve logged the training hours and passed the exams. When we tell you a clay tile is cracked at the 14-foot mark, we can show you the camera still. The certification is what taught us where to look.
HeatShield Trained, Not Just Familiar
HeatShield is not a product you buy and apply on a Tuesday; it requires manufacturer-approved training and equipment. Most sweep-only companies in the Bay Area don’t carry it because the investment is real. We did, because our clients ask for a repair path that doesn’t involve rebuilding the chimney.
Gas Fireplace Cleaning
Gas Fireplace Cleaning involves removing dust, pet hair, and mineral residue from the burner, glass, and venting system, and confirming the unit vents carbon monoxide correctly to the outside. Gas fireplaces don’t create creosote the way wood burners do, but they do accumulate fine debris that burns off as odor, and a blocked vent is deadlier because the gas is invisible. Chimney Sweep Alamo Square services direct-vent, B-vent, and vent-free gas units throughout Alamo Square, and our $180 – $340 range for a gas fireplace cleaning includes burner inspection, glass cleaning, and a vent draft test. This is a different skill set from wood flue sweeping, and we treat it as its own discipline.
Burner and Log Set Inspection
We remove the glass, inspect the burner ports for clogs, and verify the log set sits correctly so flames don’t impinge on the thermocouple or glass. Misaligned logs create sooting on the glass that returns within weeks no matter how often you clean it.
Vent Draft and CO Check
A functioning gas fireplace should draft upward and push combustion byproducts out, not into the room. We test draft with a smoke pencil and inspect the termination cap outside. If there’s a blockage, we’ll show you the video and explain the fix before we quote it.
Chimney Maintenance
Chimney Maintenance is the routine, scheduled care that keeps a fireplace safe and efficient between major repairs: annual inspections, small mortar tuck-pointing, cap tightening, damper lubrication, and seasonal checks before and after the burn season. The goal is catching minor wear before it becomes masonry work, and the economics support it; a $250 annual maintenance visit in Alamo Square is a fraction of a $6,000 liner replacement. We recommend an annual visit for wood burners, every two years for gas units, and a same-season follow-up if we see an early problem that just needs watching. The pricing model is simple: maintenance visits run $180 – $340 depending on what the system needs, and we’ll tell you in writing what can wait.
Annual Inspection Protocol
Every maintenance visit includes a camera pass through the flue, an exterior check of the cap and crown, and a firebox inspection. We document findings in a short report you keep, so next year’s visit compares against a baseline instead of starting from memory.
Pre-Season Readiness Check
Before the first fire of the season, we verify the damper opens fully, the flue is clear, the cap is secured, and the smoke shelf is clean. In Alamo Square’s older Victorians, a year of fog and wind can shift a cap or clog a flue with debris no one noticed until the first fire smoked out the living room.
Brands We Service
We service and install chimney systems built on Copperfield, DuraFlex, HeatShield, and Gelco components, which means we’re working with materials specified by professional chimney engineers, not commodity products from a shelf. Copperfield and Olympia Chimney supply trade-only channels, so when we source a cap or a flashing component, it’s the same part a chimney contractor would order, with a manufacturer behind it. DuraFlex liners are a professional-specification flexible liner we stock for full relining projects, and we size the liner to the appliance, not the other way around.
HeatShield is the one that separates repair-capable companies from sweep-only outfits. It requires manufacturer training and a certification to apply, and we use it for resurfacing clay tile liners and sealing joints where a teardown is not necessary. Gelco products handle weatherproofing, from caps to crown sealant systems, and they’re our default when the issue is water, not fire. Whether you have a Copperfield cap on a masonry chimney or a DuraFlex liner in a prefab chase, we can service it correctly.

AfterSigns You Need a Pro Right Now
- Smoke backing up into the room. This is a draft failure or a blockage, and both have immediate causes: a damper that’s not fully open, a flue clogged with a nest or creosote, or negative air pressure in the house. Burning with smoke in the room also puts carbon monoxide where your family breathes.
- A smell like campfire or tar when the fireplace is cold. That’s creosote off-gassing, and it means the buildup is thick enough to be noticeable. Humidity makes it worse, and it’s a warning sign that the flue is carrying fuel on its walls, not just exhaust.
- White or brown staining on the firebox interior. The residue means moisture is mixing with creosote, which accelerates flue deterioration. In Alamo Square’s older masonry chimneys, this is often the first visible sign of a failed cap flashing or a cracked crown.
- Flakes of tile or brick at the bottom of the firebox. If you see fragments that look like they came from inside the chimney, they did. That’s a spalled clay flue tile or deteriorating firebrick, and the flue is no longer containing heat the way it should.
- You bought the house and have never had the chimney inspected. Home inspectors flag what they can see, but they don’t run a camera up the flue. We’ve found cracked tiles, uncapped flues, and unlined chimneys in homes that passed inspection with no chimney notes at all.
Our Process, Step by Step
- 1
Booking and flat-price quote. Call (833) 620-7061, tell us what you have: wood or gas, masonry or prefab, last swept when. We quote a flat price for the sweep and inspection before we schedule the visit, so you know the number before we arrive.
- 2
Setup and containment. We protect the hearth area with drop cloths, seal the firebox opening, and run our HEPA vacuum line before the brush touches anything. The house stays clean; that’s a non-negotiable part of how we work in Alamo Square homes.
- 3
The sweep itself. Rotary brushes sized to your flue remove creosote, soot, and debris from the flue walls, smoke shelf, and damper. For gas fireplaces, we remove the glass, clean the burner and logs, and run the same dust-containment protocol.
- 4
Camera inspection and findings. After the sweep, we run a camera through the flue and show you the footage on the spot. If we see cracks, water damage, or liner gaps, you’ll see them too, and we’ll explain what each one means and what realistically needs to happen next.
- 5
Report and recommendations. You get a written summary of what we found, what we did, and what we recommend, in that order. Nothing is quoted from the roof; every repair estimate comes after the camera review, and you always see the evidence first.
How Much Does Chimney Sweep Cost in Alamo Square?
A typical chimney sweep in Alamo Square runs $180 – $340 for a wood-burning fireplace, including the flue cleaning, firebox cleanup, and a camera inspection. Gas fireplace cleaning falls in the same range but includes different work: burner inspection, glass cleaning, and vent draft testing rather than creosote removal. What moves the price: the flue’s condition (heavy glazed creosote takes longer to remove safely), the height and pitch of the roof, the number of flues, and whether repairs are needed afterward. A straightforward single-story Victorian with a clean flue will land at the low end; a three-story with a steep pitch and a second flue for the furnace will cost more.
The way to avoid overpaying is to ask for a flat price before booking and to insist on seeing camera evidence before agreeing to any repair. We quote the sweep itself as a fixed number and we don’t create repair estimates from the roof. Every recommendation comes with footage and a clear explanation. A free estimate means exactly that: call (833) 620-7061 and we’ll give you a price for the sweep before we schedule, not a vague “it depends” you only hear after we’re in the living room. If we find something that genuinely can’t wait, you’ll see it on the screen and decide from there.

Frequently Asked Questions About Chimney Sweep in Alamo Square
A chimney sweep is the professional cleaning and inspection of a chimney’s interior flue, smoke chamber, damper, and firebox. It removes creosote, soot, and debris that build up from burning wood or gas, and it includes a visual or camera evaluation of the system’s safety. In Alamo Square, a certified sweep typically costs $180 – $340 and takes 60 – 90 minutes.
A standard sweeping of one fireplace takes 60 – 90 minutes from setup to final vacuum. Gas fireplace cleaning runs about the same, though the work is different. If the camera inspection reveals damage that needs a quote, we’ll walk you through it on-site, which may add 15 – 20 minutes. Call (833) 620-7061 and we’ll tell you what to expect for your specific setup.
The standard range is $180 – $340 for one fireplace, with gas units falling in the same band. Price moves based on flue condition, roof access difficulty, and the number of flues. We give a flat quote before scheduling, so you know the number before we show up, and any repair quotes come after a camera review, never before.
Yes, and not just as a user of those brands; we’re certified to apply HeatShield for liner resurfacing and we stock and install DuraFlex liner systems for full relining jobs. These are professional-specification materials, not retail products, so most sweep-only companies can’t work with them. If your system uses these products, we can maintain and repair it correctly.
We do not guarantee same-day or emergency dispatch, and we won’t promise a crew our schedule can’t deliver. What we do offer is a booked appointment, typically within a few business days for Alamo Square addresses, and a flat price before we arrive. If your chimney is actively smoking into the house or you smell gas, stop using the fireplace immediately and call us to discuss the next available appointment.
We stand behind the quality of our sweeps and the materials we install, with manufacturer warranties on products like DuraFlex liners and Gelco caps. Our guarantee is simpler than most: if something we cleaned comes back within the expected interval because we missed it, we’ll come back. Ask Doug Lockhart about this when you book.
Clear the area around the fireplace so our crew has about four feet of workspace, and don’t light a fire for at least 24 hours before the appointment. If you have a gas unit, turn off the pilot. Keep pets in another room during the visit, since the vacuum sounds like a vacuum, and most dogs and cats don’t love it. We handle the rest, including floor protection and dust containment. Call (833) 620-7061 for a free estimate and we’ll walk you through the simple prep list.
