Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterHow Much Does Chimney Cleaning Cost in San Antonio?
A standard chimney sweep in San Antonio typically runs $150 to $300, with most single-story homes landing around $185 to $225. If your sweep turns up creosote buildup, a damaged flue liner, or a nest in the cap, expect the visit to move into the $300 to $600 range once the added work is scoped and priced. Every job we run gets a written price before a single tool comes off the truck, so the number you approve is the number you pay.
This guide breaks down what cleaning actually costs in San Antonio right now, why the price moves from one house to the next, and how to avoid the bait-and-switch that too many homeowners run into when a “specials” price turns into a different number at the door. If you want a ballpark for your house specifically, call (830) 251-4560 and a live person will pick up, day or night.
Chimney Cleaning Cost Breakdown (2026)
Here’s what the line items look like in our market this year. Ranges reflect real San Antonio jobs, not national averages pulled from a data table.
| Service | Typical Price Range | Notes |
|---|---|---|
| Standard chimney sweep (single-story) | $150 – $225 | Fireplace flue, one story, standard access |
| Standard chimney sweep (two-story) | $225 – $300 | Rooftop access adds time and safety setup |
| Level 2 inspection (with cleaning) | $275 – $450 | Video scan of the flue, checked at every joint |
| Creosote removal, heavy (Stage 2 or 3) | $350 – $900 | Glazed or hardened buildup needs more than a brush |
| Flue relining (full liner replacement) | $1,800 – $4,500 | Depends on liner type: stainless, cast-in-place, or poured |
| Chimney cap replacement | $175 – $450 | Stock vs. custom sizing and material |
| Animal or nest removal | $200 – $500 | Ranges from a single bird nest to a raccoon family |
| Masonry crown repair | $300 – $800 | Cracked crown lets water into the stack |
Those numbers are what you should see when you get a written estimate. If a company quotes you $79 for a sweep and then hands you a $1,400 invoice for “urgent” liner work you never asked about, the fair price wasn’t the issue. The process was. We hand you the written price first. If the inspection turns something up, we show you the video and price the repair separately, and you decide.

What Affects Chimney Cleaning Pricing in San Antonio
Six things move the number more than anything else. Every San Antonio sweep we do is priced against these.
- Number of stories. A single-story fireplace can be reached from the ground with the right setup. A two-story roof in Stone Oak or Alamo Heights means a ladder, a rooftop safety kit, and more time. That’s the biggest single jump in price, usually $70 to $90.
- How much creosote has built up. Occasional weekend fires leave light, flaky creosote that brushes out fast. A homeowner burning green mesquite or unseasoned oak logs year after year can end up with glazed Stage 3 creosote, which is dense and hard and takes a rotary tool to remove. That’s the difference between a $200 sweep and a $700 one.
- Flue size and shape. A standard rectangular fireplace flue is straightforward. A wood stove with a smaller round flue, or a house with two flues in the same stack, takes longer and costs more to service.
- Access and roof pitch. A steep roof, a low-hanging tree branch over the cap, or a chimney tucked behind a second-story valley all affect how long the job takes and how much safety gear is needed.
- What the inspection finds. A sweep that reveals a cracked tile liner, a missing cap that let water in, or a rusted damper adds a repair line to the visit. That’s not padding; it’s what the video shows you. We walk it through with you before anything gets scheduled.
- When you book it. The busiest window in San Antonio runs from October through January, when the first cold front hits and everyone remembers the fireplace. Spring and summer bookings are easier to schedule and often get the same price with more flexibility on timing.
Here’s a local detail that matters: San Antonio’s mix of live oak, mesquite, and pecan means a lot of homeowners burn wood that isn’t fully seasoned. Mesquite especially burns hot but leaves heavy residue if it hasn’t dried down. We see more Stage 2 creosote here than you’d expect for a mild-winter market, and the price reflects the extra removal time. If you’re burning mesquite, plan on an annual sweep rather than skipping a year.
What’s Included in a Standard Chimney Sweep
A sweep isn’t just running a brush up the flue and calling it done. Here’s what a real one covers:
- Removal of soot, ash, and creosote from the firebox, smoke chamber, and flue
- Cleaning of the damper and smoke shelf area
- A visual check of the firebox, damper, and cap
- A drop cloth and vacuum setup so dust stays in the chimney, not on your rug
- Photos or video of anything that looks off, shown to you before we leave
What’s not included at the base price: a full Level 2 inspection with video scanning, any repair work, and liner replacement. Those are separate line items, and each gets its own written price before we start.
How Often Should You Have Your Chimney Cleaned in San Antonio?
For most San Antonio homes that burn regularly during the cool months, once a year is the right cadence. If you burn more than three cords a year, or you’re burning mesquite or unseasoned wood, book it twice. If you use the fireplace only a handful of times a season, an annual inspection still makes sense, because creosote isn’t the only issue. Water intrusion, cracked crowns, and animal nesting all happen whether you light a fire or not.
The trade standard most sweeps work from is the one-inch rule: if creosote has built up to a quarter-inch or more, it needs to come out. A glazed, shiny, hardened layer is a fire hazard and needs immediate removal.
How to Save on Chimney Cleaning
A few things actually lower the bill, and a few only look like they do.
- Book in the off-season. Spring and early summer are the slowest months in San Antonio. You get the same work with more scheduling room and no scramble for a cold-weather appointment.
- Combine cleaning with your annual inspection. A cleaning plus a Level 2 inspection done on the same visit is almost always cheaper than two separate trips.
- Burn seasoned wood only. Wood that’s been split and dried for at least six months to a year produces less creosote per fire. That’s the cheapest long-term move you can make.
- Fix the cap before the water gets in. A $200 cap replacement beats a $2,000 masonry repair every time. Water damage to a chimney is one of the most expensive problems we see, and the cheapest to prevent.
- Skip the door-to-door specials. If a company can’t give you a written price before the visit, they’re not saving you money; they’re moving the number around. A written, upfront price is the only way to actually compare two bids.
The honest way to compare bids is to ask for the price in writing first. We do that on every job. Call (830) 251-4560 and we’ll walk through what your house needs and what it costs before we schedule a thing.
Repair vs. Replace: When Does Cost Tip One Way?
If the sweep turns up a problem, the first question is always whether to repair or replace. A few rules of thumb:
- A single cracked flue tile or a hairline crack in the crown: repair it. That’s $300 to $800 and solves the problem.
- A liner that’s failed along its length, or a chimney with no liner at all: reline it. A full stainless liner runs $1,800 to $4,500, and it brings the chimney back to safe, usable condition.
- A firebox with cracked firebrick and a liner that’s also shot: this is where we price both options and give you the numbers side by side.
- Chimney in good shape with only cosmetic masonry wear: clean it and leave it. No upsell needed.
We don’t push replacement when repair will do. Every repair we do carries our 365-Day Done Right Promise, which is a written guarantee that the work is covered for a full year. If a covered repair fails inside that window, we come back and fix it at no charge. That’s not a sales line; it’s on the invoice.
Why Homeowners Call Flint Chimney Sweep
Most people who call us have already had one bad experience. A crew that showed up late, or didn’t show up at all. A price that grew between the quote and the invoice. Ash left on the hearth. That’s who we built the process around.
- Written price before any work starts. No exceptions, on every job. You approve it, and that’s the number.
- The 365-Day Done Right Promise. Every repair is covered in writing for a full year. If it fails, we return for free.
- Background-checked, uniformed technicians. You know who’s knocking on your door and why they’re there.
- A live person on the phone 24/7. No voicemail, no callback form, no waiting until Monday morning.
- Professional-grade materials. We spec DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield by the job, not by what’s closest on the shelf.

FAQs – Chimney Cleaning Cost
How much does chimney cleaning cost in San Antonio?
Most San Antonio chimney sweeps run $150 to $300, with a single-story standard cleaning landing around $185 to $225. Two-story homes, heavy creosote, or an added inspection push the total toward $400 and up. Call (830) 251-4560 for an exact written price, free of charge.
Can I clean my chimney myself?
The cleaning itself is not the dangerous part, but the job can’t be done safely from the ground, and climbing a roof without fall protection is a real hazard. Rotating brushes, chimney vacuums, and drop-cloth setups aren’t cheap either, and a homeowner can’t inspect the flue for cracks while cleaning it. Cleaning starts around $150, so the tools and risk usually aren’t worth it. Call (830) 251-4560 and we’ll get it scheduled.
How often do I really need a chimney sweep in San Antonio?
Once a year for most homes, twice if you burn more than three cords or use mesquite heavily. The one-inch rule is the standard: a quarter-inch or more of creosote means it’s time. An annual sweep is far cheaper than a liner replacement, which runs $1,800 to $4,500. Call (830) 251-4560 to book.
Why did one company quote me $79 and another $250?
The $79 quote is almost never the real price. It’s a door-opening price that turns into a much larger number once the technician is in your house. A written price before the visit is the only way to compare bids fairly. Get your written number from us first. Call (830) 251-4560.
Do you charge extra for a two-story chimney?
Yes, usually $70 to $90 more than a single-story sweep, because of the added rooftop access and safety setup. A two-story standard sweep typically runs $225 to $300. Call (830) 251-4560 and we’ll give you the exact written price for your house.
What if the sweep finds a repair you didn’t expect?
We show you the video, explain what we’re seeing, and price the repair separately. Nothing gets done until you approve it in writing. If you decide not to do the repair now, that’s fine; we’ll note it for next time. Call (830) 251-4560 with any questions.
