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.

Why Flint Chimney Sweep Is Sonterra’s Preferred Chimney Sweep Company
Sonterra homeowners deal with a specific kind of chimney stock, and we know it well. Most houses here are newer hill-country construction, which means factory-built fireplaces with stainless flue liners and metal chase caps rather than old masonry stacks. Our Chimney Sweep team sees more DuraFlex liners and chase-style caps in one month in Sonterra than most companies see in a year. That matters when a chase cap cracks or a liner warps, because the fix is different from what an all-brick fireplace needs.
Every tech we send into Sonterra is background-checked and uniformed, so you know exactly who is walking through the door. We operate under the Garrison Standard, the same code every Garrison Partners location follows. That means a written price before work starts, every time, no exceptions. Hank Delano leads our crews, and he runs things the way a disciplined tradesperson should: name the problem, show you the problem on camera, and tell you plainly if the work can wait. We don’t upsell, and we don’t invent repairs. If a covered repair fails within 365 days, we come back at no charge.
Chimney Cleaning in Sonterra
Chimney Cleaning in Sonterra is the core of what we do, and it starts with knowing whether you have a masonry flue or a factory-built metal liner. Most Sonterra homes fall into the second camp, which means the work is a brush pass on a stainless liner, often combined with pulling and inspecting the chase cap up top. We also sweep traditional masonry flues in the older pockets around the area. A standard sweep runs $189 – $340, and that price is written down before we start. It covers the brush work, removal of creosote and soot from the flue, and a camera inspection afterward with a photo report you keep.
Creosote and Soot Removal
Creosote is the residue left behind when wood smoke cools and condenses inside the flue. It comes in degrees: first-degree is flaky soot, second-degree is crusty and harder, and third-degree is glazed over. Soot removal is a routine part of the sweep. Creosote removal is the same brush pass but a heavier job when the buildup is second-degree or worse. We tell you what degree you have, show it on camera, and tell you straight if a chemical treatment is worth it or if you can wait a season.
Annual Sweep
Most Sonterra homeowners need an annual sweep if they burn 25 or more fires a season. If you hardly light the fireplace, you might stretch to 18 months, but the inspection is still worth doing yearly. That’s because a cracked chase cap or pulled flashing seal lets rain and rodents in whether or not a fire was ever lit. We recently worked a home off Sonterra Boulevard where the fireplace had been closed for two seasons. The firebox was a factory-built unit with a DuraFlex liner, and the damper had stuck open, so the chase had been drafting cold air and pulling grit down past the smoke chamber. We brushed the liner, freed the damper, and found first-degree creosote throughout. No glazing, no repair needed. We wrote it up as a routine clean and delivered the photo report that afternoon.
Fireplace Cleaning in Sonterra
Fireplace Cleaning in Sonterra covers the firebox, the damper, the glass doors if you have them, and the visible masonry surface around the opening. A lot of homeowners confuse this with the sweep, but they’re two different jobs. The sweep handles the flue. The fireplace cleaning handles everything below it. In Sonterra’s newer construction, the firebox is usually a factory-built metal unit, not brick, so we clean it with brushes and a HEPA vac, not water or chemicals. This runs $129 – $249 depending on the amount of ash, soot staining, and whether the damper needs attention. It’s typically done alongside the sweep on the same visit.
What We Check During a Fireplace Cleaning
We check the damper travel, the firebrick or refractory panels, and the seal around the glass. A stuck-open damper is a common issue in Sonterra because the chase-style caps let cold air pour down when the fireplace sits unused. That keeps the firebox gummy and weakens the draft. A brush clean won’t fix that. We’ll tell you if the damper needs to be freed or if the refractory panels show hairline cracks that should be monitored versus replaced.
How a Fireplace Cleaning Differs From a Sweep
The sweep is about the pathway smoke travels through. The fireplace cleaning is about the box where the fire actually burns. You can book one without the other, but most Sonterra homeowners do both at the same time because the firebox and the flue share the same opening. If we’re already on site and the ladder is up for the chimney, the fireplace cleaning adds an hour or less and gets the whole system squared away in one visit.
Trusted Brands We Service in Sonterra
We work with professional-grade chimney materials that are specified by job, not by margin. In Sonterra, that means a lot of DuraFlex stainless liners and Copperfield and Famco components that come standard on factory-built hillside construction. If your chase cap is cracked or your liner shows warping or spalling on the camera, we can source the replacement part quickly because we stock the common sizes for the flue configurations we see most. We don’t push a brand that isn’t right for your setup. We tell you what’s on the house now, what the options are, and what the written price covers.
Common Chimney Sweep Problems We See in Sonterra Homes
- Skipped inspections because “we didn’t burn much.” A metal chase cap can crack or a flashing seal can pull loose even with zero fires lit. Rain, wind, and critters don’t care how often you use the fireplace. We find this constantly across Sonterra’s newer developments, and it usually means moisture damage that an annual inspection would have caught early.
- Stuck-open dampers paired with chase-style caps. The damper lets cold outdoor air pour down the flue, so the firebox stays gummy and the draft stays weak. A simple cleaning won’t fix this. The damper has to be freed or replaced, and we always verify it on camera before recommending the repair.
- Wire-brushing a factory-built liner when the real issue is structural. A warped or spalled section of stainless liner won’t improve with a brush pass. In Sonterra, where most flues are metal, the camera inspection is the difference between a cheap clean that masks a problem and an honest call on what needs a heat-rated repair.
- Third-degree creosote that looks like first-degree from the firebox. You can’t see the upper flue from the hearth. Only a camera can show whether that flaky buildup at the bottom is matched by glazed creosote further up. Glazed creosote is a chimney fire risk, and it’s why we won’t write up a sweep without showing you the footage.
Pricing for Chimney Sweep in Sonterra, TX

- Standard chimney sweep: $189 – $340. Includes brush work, creosote and soot removal, and camera inspection with photo report.

What moves the price is flue height, creosote degree, and whether the liner is factory-built metal or masonry.

FAQs About Chimney Sweep in Sonterra
If you burn 25 or more fires a season, sweep once a year. If you light the fireplace rarely, you can usually go 18 months between sweeps, but the inspection should still happen annually. That’s because a cracked chase cap or a pulled flashing seal lets rain, wind, and rodents into the flue whether or not a fire was lit. Sonterra’s factory-built construction means the metal components degrade even when the fireplace sits unused. Call (830) 251-4560 and we’ll give you a straight answer on your specific situation based on the camera footage, not a general rule.
No. We book by appointment, and we don’t use scarcity tactics or false urgency. Chimney work in Sonterra is seasonal, and doing it right matters more than doing it fast. When you call, we give you a real scheduling window and we show up inside it. If you need a specific date because you’re listing a home or closing on one, tell us and we’ll work with your timeline as best the schedule allows.
The flat price covers the full sweep, creosote and soot removal, and the camera inspection with a photo report. That report is not an add-on. You see what we see, on a screen or printed out, before you agree to any repair. If the camera shows no glazing and no structural damage, we write that up and you’re done. If it shows something that needs attention, you get a written price for the repair before any additional work starts.
Creosote comes in three degrees. First-degree is flaky soot, normal and removable with a standard brush pass. Second-degree is crusty and darker, a sign you should sweep sooner and maybe burn drier wood. Third-degree is glazed and shiny, and that’s a chimney fire risk that needs chemical treatment or mechanical removal beyond a standard sweep. We show you the degree on camera during the inspection. No one should tell you a flue is dangerous or fine without showing you the footage. Call (830) 251-4560 and we’ll do exactly that.
You can wait if the camera shows first-degree creosote with no glazing, the damper closes fully, and the chase cap is intact with no cracks or animal entry. That’s a routine clean, do it once a season, and you’re fine. You should not wait if the liner shows warping or spalling, the damper is stuck open, or third-degree creosote is present. Those are not optional. We’ll always tell you which camp you’re in, with the footage to back it up. If we say it can wait, we mean it.
