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.

AfterFast, Reliable Chimney Sweep Across Johnson City
A standard chimney sweep in Johnson City typically runs $189 – $289, and most jobs are completed in under two hours. That price covers the full flue cleaning, a basic safety check of the firebox and damper, and a written report of what we found. If you burn wood as real heat through a Johnson City winter, you’re asking more of your chimney than most Tennessee homes ever do. Call (336) 863-3889 and we’ll get you on the schedule before the next cold snap settles into the valley.
Our crews work throughout Johnson City, from the bungalows off Sunset Drive near ETSU to the ranch homes spread across the north and east sides. We know these chimneys. We know the clay-tile liners that have been freezing and thawing for seven decades, the unlined masonry stacks that were never built for modern appliances, and the creosote that builds faster here than in Knoxville or Chattanooga. That local knowledge changes what we look for and what we recommend. Our Chimney Sweep team treats every Johnson City home as its own job, not a stop on a route.
Why Alcott Chimney Sweep Is Johnson City’s Preferred Chimney Sweep Company
Alcott Chimney Sweep has been serving homeowners since 2002 as part of the Threshold Group family of home-service companies. That’s more than two decades of sweeps, inspections, and repairs across northeast Tennessee, and it shows in how we handle a Johnson City chimney. We don’t rush a flue because there’s another job waiting in Bristol. We take the time to run a camera when something looks off, and we show you the footage before we quote a single repair.
Every technician who arrives at a Johnson City home is background-checked, identity-verified, uniformed, and announced to you by name and photo before the visit. That’s the Threshold Standard, and it’s non-negotiable. When you open your door, the person standing there matches the person you were told to expect. For homeowners who are often home alone, parents with young children, or older residents who want certainty about who’s coming, that matters as much as the sweep itself. Ruben Castellano runs Alcott with a simple rule: you should never have to guess who’s walking up your driveway.
We answer the phone with a live person, around the clock. If something smells like smoke at 11 p.m. in Johnson City, you’ll talk to a human being, not a voicemail queue. And every job comes with a written price before any work begins, plus a written guarantee on every repair. If a repair fails within the coverage period, the second visit is free. That’s our 365-Day Done Right Promise, and it applies to every completed job in Johnson City.
Chimney Sweep Certified in Johnson City
A Chimney Sweep Certified job in Johnson City means we’re not just running a brush up the flue and calling it done. It means a full mechanical sweep of the flue and smoke chamber, removal of creosote and soot down to the firebox, a visual check of the damper, cap, and flashing, and a written report of everything we saw. Johnson City homeowners whose fireplaces function as genuine heat sources, not decorative accents, need this level of work every single year.
A standard chimney sweep in Johnson City runs $189 – $289 before any repairs. When we find damage, we show you the camera footage. You never get a reline quote based on our word alone.
Creosote and Soot Removal
Creosote, the tar-like buildup that causes chimney fires, accumulates fast in Johnson City because cold valley winters push homeowners to burn hot, long fires. We remove glaze-stage creosote with rotary tools when a standard brush won’t cut it. Soot is the lighter, dusty layer that comes from incomplete combustion, and we clear it from the firebox, damper, and smoke shelf on every sweep.
Level 1 and Level 2 Inspections
A Level 1 inspection is included with a standard sweep and covers the accessible parts of the chimney. A Level 2 inspection, which runs $249 – $449 in Johnson City, adds a camera scan of the flue interior. That camera is how we find cracked clay tiles, failed mortar joints, or hidden creosote that a visual check would miss. Older homes around ETSU and the historic downtown core should get a Level 2 on their first visit with us.
Gas Fireplace Cleaning in Johnson City
Gas Fireplace Repair - Johnson City service isn’t just about vacuuming the logs. Gas units still collect dust, pet hair, soot, and mineral deposits on the glass and burners, and a dirty burner produces carbon monoxide that can spill into the room. Johnson City homes that use gas fireplaces as a supplement to a heat pump still need the burner assembly cleaned, the glass polished, and the venting checked at least every two years.
A gas fireplace cleaning in Johnson City typically runs $149 – $249. If the unit hasn’t been serviced in years, expect to pay toward the upper end.
Gas Logs and Burner Service
We remove the logs, clean each one, clear the burner ports with compressed air, and check the pilot assembly and thermocouple. A burner that’s partially clogged burns unevenly and produces excess carbon monoxide. After cleaning, we test the unit and check for proper flame color.
Glass and Venting Check
Mineral haze on fireplace glass is normal, but it should be cleaned with the right product so it doesn’t etch. We also check the vent termination outside the home for blockages. Wasp nests, leaves, and even bird debris show up in Johnson City vents regularly, and a blocked vent is a carbon monoxide risk inside the house.
Trusted Brands We Service in Johnson City
We install and service professional trade materials, not box-store substitutes. That includes Olympia Chimney caps and dampers, Famco venting, Copperfield chimney products, and DuraFlex liner systems. For our Chimney Sweep customers in Johnson City, stocking these brands locally means faster turnaround on repairs. When a cap is rusted out or a damper is warped, we’re not waiting on a special order from a warehouse in another state. We carry what these homes need, and if we don’t have it on the truck, we can usually have it within a day or two.
Common Chimney Sweep Problems We See in Johnson City Homes
- Clay-tile flue liners cracking from freeze-thaw. The older craftsman bungalows and brick colonials in Fairview, Sunset Park, and the historic downtown core have original clay tiles that have been through 70-plus years of Johnson City’s hard freeze-thaw cycles. Once those tiles spall, the flue loses its insulation and fire protection.
- Unlined or single-wythe masonry chimneys. Postwar ranch homes on the east and north sides were often built with chimneys that were never meant to vent wood stoves or modern gas appliances. That creates draft problems and spillage, which is a safety issue, not just a nuisance.
- Glaze creosote from valley temperature inversions. Johnson City sits in a valley ringed by Iron Mountain, Holston Mountain, and Buffalo Mountain. When inversions trap cold air, drafts weaken, and homeowners respond by burning hotter fires. Hotter fires build glaze creosote faster than anything else.
- Rental chimneys near ETSU with hidden Stage 3 creosote. Successive student tenants burning cheap or wet firewood can leave flues loaded with third-degree creosote that the current owner doesn’t know exists. A standard sweep alone won’t confirm it’s gone. A Level 2 camera scan will.

FAQs About Chimney Sweep in Johnson City
Once a year, at minimum. Johnson City sits at about 1,650 feet in a valley ringed by Appalachian ridges, and winters here are cold enough that fireplaces and wood stoves run as actual heat sources, not occasional ambience. That heavy seasonal use means creosote builds faster here than in lower-elevation Tennessee cities where fireplaces are lit a handful of times each winter. If you burn every day from November through March, schedule your sweep in late summer or early fall so you’re clean before the first fire. Call (336) 863-3889 and we’ll get you on the calendar.
Yes, with a camera. The only way to know if your 70-plus-year-old clay-tile liner is cracked, spalled, or failing is to run a Level 2 camera scan. We swept a 1940s brick colonial off Sunset Drive near ETSU where the tenant had burned wet wood for two winters against a liner already damaged by freeze-thaw. The camera showed Stage 3 glaze creosote in the smoke chamber. We didn’t quote a reline. We ran a rotary sweep, applied HeatShield to the failed joints, and passed the camera back up the flue so the homeowner could see it clean. If your liner needs work, you’ll see the footage before you see a price. Call (336) 863-3889 for a free estimate.
Third-degree creosote, also called glaze creosote, is a hardened, tar-like coating that forms when flue temperatures are high and the creosote bakes onto the liner. It matters more in Johnson City because our valley-and-ridge topography can create temperature inversions that weaken chimney draft. When draft is weak, people burn hotter fires to compensate. Hotter fires build glaze faster. Knoxville and Chattanooga sit lower, with less inversion activity, so their chimneys rarely see the same rate of glaze buildup. If you’ve got glaze creosote, a standard brush won’t remove it. We use rotary tools, and we’ll confirm the flue is clean with the camera before we leave.
Probably not. Rental homes near the ETSU campus get rebuilt fires on cheap or wet wood by successive tenants, which loads the flue with creosote quickly. The current owner often has no idea what’s in there. We recommend a Level 2 inspection with camera scan on any rental that’s changed hands, even if it’s just to document what’s in the flue. That camera will show whether the chimney is clean, has light creosote, or is carrying third-degree glaze that needs rotary removal. You’ll also get a written report you can keep for your records or share with a prospective buyer. Call (336) 863-3889 to schedule.
Yes. Gas fireplaces produce less creosote than wood, but they still collect dust, pet hair, mineral deposits on the glass, and carbon buildup on the burners. A dirty gas burner can produce carbon monoxide that spills into your living room. We recommend having a gas fireplace cleaned every two years, more often if it’s your main heat source. The job includes pulling the logs, clearing the burner ports, polishing the glass, and checking the vent termination outside. In Johnson City, wasp nests and leaf debris in vent caps are common. Call (336) 863-3889 and we’ll get it done.
