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 Duncanville’s Preferred Chimney Sweep Company
Duncanville homeowners call us for one reason more than any other: they’ve been quoted work they couldn’t verify. A liner replacement off a driveway glance. A rebuild they didn’t need. We handle it differently. Every sweep and inspection in Duncanville starts with a camera scan and ends with a photo report showing exactly what we found, where it was, and what it means.
Our crews work throughout Duncanville regularly. We know the older masonry chimneys off Camp Wisdom Road, the 1970s builds near Red Bird Lane, and the newer prefab units going up out by Cedar Ridge. That matters because the job scope differs block to block. We don’t run a generic sweep checklist. We run the inspection the house calls for.
Scheduling is coordinated from our Dallas-Fort Worth office, but crews are dispatched locally to Duncanville and carry the Garrison Standard on every call. The phone is answered by a live person 24 hours a day. Technicians are background-checked and uniformed. Every repair gets a written guarantee valid for one full year.
Hank Delano has built this operation on a simple standard: document everything, quote everything, guarantee everything. That’s why our Duncanville customers keep our number saved. Call (830) 251-4560 for a free estimate.
Chimney Cleaning in Duncanville
Chimney Cleaning in Duncanville means removing creosote and soot from the flue, firebox, and smoke chamber, not just running a brush up the middle and calling it done. Creosote is the tar-like residue left behind when wood smoke cools inside the chimney. It builds faster in North Texas because our winters go hot-cold-hot, and that temperature swing makes smoke condense on flue walls instead of venting clean.
A standard chimney cleaning in Duncanville runs $159 – $289. That includes our full sweep process, a camera inspection of the flue, and the photo report. We sweep from the top down with brushes sized to the flue, then clean the firebox and smoke chamber by hand. The work usually takes 45 to 90 minutes.
Creosote Removal
First-degree creosote is flaky and brushes out. Second-degree is tar-like and needs rotary tools. Third-degree is baked-on and glossy, and it is a fire hazard. In Duncanville homes with older masonry flues, we regularly see first and second-degree buildup concentrated in the upper third of the chimney, where the flue cools fastest during short winter fires.
Soot Removal
Soot is fine, black powder, less flammable than creosote but still corrosive to flue liners and dampers. Gas fireplaces in Duncanville primarily produce soot, not creosote. We remove soot from the firebox, damper, and smoke shelf as part of every sweep, then show you the before and after on camera.
Annual Sweep
If you burn wood regularly in Duncanville, an annual sweep is the right cadence. Most of our customers book theirs in September or October, before the first cold snap. If you burn twice a week or less, every other season may be enough. We’ll tell you straight what your flue shows.
Fireplace Cleaning in Duncanville
Fireplace Cleaning in Duncanville is part of every Chimney Sweep we perform, and it includes the firebox, glass doors, damper, and surrounding hearth. We don’t leave a dust line across your mantel or ash smeared on the brick. The work area is protected with drop cloths, and we use HEPA-filtered vacuums to keep the dust out of your living room.
Fireplace cleaning alone, without the flue sweep, runs $109 – $149 in Duncanville. For wood-burning fireplaces, we recommend the full sweep because creosote in the flue won’t show at the firebox level. Gas fireplaces are different: we clean the gas logs, ceramic glass, blower, and pilot assembly, and most Duncanville gas units need this once a year if they’re used seasonally.
Wood-Burning Fireplace Cleaning
The firebox gets hand-brushed and vacuumed. The damper is checked for rust and free movement. We inspect the firebrick for cracking and the lintel bar for sag. If the firebox is sound and the flue is clean, we’ll tell you that and nothing more.
Gas Fireplace Cleaning
Gas units in Duncanville collect soot on the logs and interior glass, and dust builds up in the blower. We clean all of it, test the pilot and thermocouple, and check for gas leaks at the connection. If we find a leak, we shut the valve and tell you before we leave. We don’t leave a safety issue running.
Trusted Brands We Service in Duncanville
We work with professional-grade chimney materials and parts, not whatever is cheapest at the supply house. For Duncanville homes, that means DuraFlex flue liners when a reline is genuinely needed, Olympia Chimney dampers and caps, and HeatShield for crown repairs and flue joint sealing. When we quote repair work in Duncanville, the brand is named on the written estimate, so you can verify the material independently. We stock common parts for faster turnarounds on Duncanville jobs, and we never substitute a knockoff because it carries a better margin.
Common Chimney Sweep Problems We See in Duncanville Homes
- Creosote buildup in older masonry flues: Duncanville’s mid-century ranches often have unlined or clay-tile-lined flues that cool smoke fast, and that means first and second-degree creosote concentrated in the upper flue. Sweeping only the firebox leaves the real fuel load untouched.
- Spalling crowns and washed-out mortar joints: North Texas hail and freeze-thaw cycles tear at chimney crowns and mortar. In Duncanville, a crown with hairline cracks lets water into the smoke chamber, and what starts as a $300 HeatShield repair becomes a rebuild if it goes unaddressed for years.
- Damaged or missing chimney caps in post-storm homes: After a hailstorm rolls through Duncanville, we get calls for water in the firebox. The cause is usually a dented or blown-off cap, not a liner failure. A camera look settles it in ten minutes.
- Partially swept chimneys from previous companies: We regularly follow other companies in Duncanville and find the flue brushed but the smoke chamber never touched. The brush leaves what the fire needs. We sweep the full path, every time, and document it.
Pricing for Chimney Sweep in Duncanville, TX
A standard chimney sweep in Duncanville runs $159 – $289 for a single flue, depending on the flue type and the amount of creosote present. A Level 1 inspection is included with every sweep. A Level 2 inspection, which adds the video scan of the flue interior and the accessible attic and crawlspace areas around the chimney, runs $110 – $180 in Duncanville. Fireplace-only cleaning runs $109 – $149.
What moves your price within those ranges: two-story homes cost more than single-story because of access. Masonry flues with clay tile liners take longer than prefab metal flues. Heavy third-degree creosote needs rotary tooling and adds labor. Your written price is set before we start, after we see the chimney and the flue, and it does not change at the door.

FAQs About Chimney Sweep in Duncanville
If you burn wood more than twice a month during winter, once a year. If you burn occasionally or only on the coldest nights, every other year is usually enough. Gas fireplaces need the blower and logs cleaned annually if used as a primary heat source, but the flue itself rarely needs a sweep. We’ll tell you what your flue actually shows on camera and give you a straight recommendation, even if that recommendation is “you can wait.” Call (830) 251-4560 to schedule a sweep and see for yourself.
A Level 1 inspection checks the accessible portions of the chimney: the flue, damper, firebox, smoke chamber, and exterior. It’s included with every sweep. A Level 2 inspection adds a video camera scan of the flue interior and an assessment of the attic and crawlspace areas around the chimney. In Duncanville, we recommend Level 2 after a hailstorm, after a chimney fire, or when you’re buying a home. The camera evidence is yours to keep, and it’s the difference between a quoted reline and a crown repair that was the actual problem. Call (830) 251-4560 and we’ll talk through which level fits your situation.
Yes. The written price is set before we start, and it is the same number on the invoice. The only reason we confirm the price after seeing the chimney is that flue type and creosote volume affect labor. What we will never do in Duncanville is arrive with a flat number, then add “found more” charges on site. That practice is exactly why our written-price policy exists. Call (830) 251-4560 for a free estimate.
Third-degree creosote is baked-on, glossy, and highly concentrated fuel coating the flue walls. It forms when fires burn cool or when creosote layers are never removed. It’s a chimney fire risk, and it can’t be brushed out with a standard sweep, it needs rotary tooling or chemical removal. In Duncanville, we most often see third-degree in homes where a previous company swept the flue but skipped the smoke chamber, so creosote baked against the upper flue over multiple seasons. Call (830) 251-4560 and we’ll show you on camera exactly what grade is in your flue.
Mostly, it can wait. First and second-degree creosote is a maintenance issue, not an emergency, and you can schedule the sweep around your calendar. What should not wait: a chimney fire, smoke backing into the house, or water pouring through the firebox during a storm. If you’re unsure, call (830) 251-4560 and describe what you’re seeing. We’ll give you a straight answer on urgency and never push a service you don’t need this week.
We ran a Level 2 inspection on a 1950s ranch off Main Street in Duncanville where the homeowner hadn’t had the chimney looked at in eleven years. The firebox was sound, but first-degree creosote had built up through the flue liner, and the chimney crown had hairline cracks letting water into the smoke chamber. We swept it, swapped the damaged damper, and applied a HeatShield crown repair rather than quoting a rebuild, because the mortar joints tested solid and the work could safely wait for the next dry stretch. That’s the job done right: evidence first, repair second, and no rebuild quoted where a repair holds.
Duncanville’s housing stock swings from mid-century ranches near Downtown Duncanville to newer two-story builds out toward Cedar Ridge, and the two fail differently. Older masonry chimneys here tend to show spalling crowns and washed-out mortar joints. Newer prefab units usually just need a flue liner check and a cap that survived the last hailstorm. That split means our sweep and inspection scope in Duncanville is never one-size-fits-all. A 1962 ranch off Wheatland Road gets a different camera path than a 2018 two-story near Cedar Ridge, and we quote accordingly.
